Описание: evergoodlocks.com Mechanical locks are the backbone of your security system. There are three types of tumbler locks: pin-tumbler, disk-tumbler, and lever-tumbler. Pin-tumbler locks are the most common. The tumblers in this type of lock are small pins. The modern door lock is a compact pin-tumbler cylinder lock of the type developed (1860) by the American inventor Linus Yale. Most high-security locks have pin tumblers. Disk-tumbler locks are often used in desks and file cabinets. Lever-tumbler locks employ a series of different-sized levers resting on a bolt pin to prevent the bolt from moving. When the proper key is inserted, all the levers are raised to the same height, enabling the bolt pin to release the bolt. Lever-tumbler locks are often used in briefcases, safe-deposit boxes, and lockers. Pin-tumbler locks can be keyed to your existing key, master keyed and re-keyed over and over. They come in many architectural styles and finishes to suit your taste and building style.Deadbolts can be keyed on one side with a turn knob on the other, keyed on both sides, Keyed or turn knob on one side only. Your bolt should extend at least 1 inch from the edge of the door. Many older deadbolts have a much shorter "throw" and it is not enough to prevent the door from being pried open. Deadbolt strength is dependent upon the strength of the JAM, or what the bolt goes into. Jams can be reinforced with many products to make it much more difficult for intruder to bypass the lock. Latch locks refer to locks that have a beveled, spring loaded bolt that slides past the jam edge and drops into the hole. These locks keep the door shut when closed, generally give you a knob or lever to pull or push the door open/closed and provide some degree of security. But not nearly the security of a deadbolt lock. The newer latches have a pin which, when properly installed does not allow the latch to be pushed back by a credit card or other means when the door is closed and locked. Proper installation is the key here. These kinds of mechanical locks can be used for many places, for example they can be used as Drawer Lock, Cam Lock, Glass Door Lock, Cabinet Lock and Wardrobe Lock. Even with an alarm and an armoured door, if you haven't got a good quality lock, a burglar could easily force it and enter the house undisturbed. Crime data regularly compiled by the Home Office show that most burglars (almost 70%) force the front door. About 20% come in through the window and the rest don't actually break in: they gain entrance because the homeowners have forgotten to lock the door.Home security begins with the front door, lock and cylinder that you choose. But with so many options to choose from, how do you go about finding the lock that best meets your needs? Locks aren't something you buy every day: they are usually purchased when building a new home or renovating your existing one. We often don't have a say in the matter and are not fully aware of the choice made.If you ever have to buy or replace a lock, remember to bear in mind a couple of variables such as the type of door/window you are going to install it on, the quality of the structure it is going into and the level of security you want. Basically, no single lock can satisfy all needs. For instance, the lock you choose for an armoured door will be different from that for a wooden or aluminium door. Or, if the structure of the door is weak or damaged, it will inevitably be less secure, regardless of the type of lock you install. Even the best lock in the world is useless if installed on a weak door. For example, some garage doors in apartment buildings are made of sheet metal that is so thin, it can easily be cut and manipulated, without even having to touch the lock.And if you always forget your keys for the lock, aDigital Lock or Smart Locks like Fingerprint Lock and Password Lock are also great choice.

Описание: delinpump.com One of the first pieces of powered machinery to be invented at the dawn of the industrial age was a crude form of pump. The pump has since evolved into an endless variety of types, sizes, and applications. A functional understanding of pumps, their use, and application, is essential to understand how most processes are handled in process plants today. Pump is a machine or mechanical equipment which is required to lift liquid from low level to high level or to flow liquid from low pressure area to high pressure area or as a booster in a piping network system. Principally, pump converts mechanical energy of motor into fluid flow energy.Pump also can be used in process operations that requires a high hydraulic pressure. This can be seen in heavy duty equipment’s. Often heavy duty equipment’s requires a high discharge pressure and a low suction pressure. Due to low pressure at suction side of pump, fluid will lift from certain depth, whereas due to high pressure at discharge side of pump, it will push fluid to lift until reach desired height. Pumps may be classified on the basis of the applications they serve, the materials from which they are constructed, the liquids they handle, and even their orientation in space. All such classifications, however, are limited in scope and tend to substantially overlap each other. A more basic system of pump classification is based on the principle by which energy is added to the fluid. Under this system, all pump types generally fall into two main categories: Dynamic (Centrifugal) Pumps – Energy is continuously added to increase the fluid velocities within the machine.Positive Displacement Pumps – Energy is periodically added by application of force to one or more movable boundaries of enclosed, fluid-containing volumes.These are further divided into many forms. For simplification of article we will discuss these many forms separately in separate articles. A pump is any device meant to facilitate the motion of a fluid. Pumps displace fluids, causing it to move down or out of a pipe. Most pumps use some sort of compressional action to displace the fluid. This compressional action sometimes necessitates a motor that acts to put pressure on the fluid in order to displace it. This motor can be powered by a variety of fuels, as long as it has the necessary power to displace the fluid. Most pumps are either positive displacement or rotodynamic. Positive displacement pumps function by trapping and displacing amounts of a fluid. This causes the fluid to be displaced and move along the length of the pump and through its discharge. The fluid must be continually displaced in order for fluid to keep being discharged from the pump.Rotodynamic pumps use motion to generate more energy in a fluid and then cause the fluid to move along a pipe. Pumps such as these generally use a motor to turn a device that will increase pressure on a fluid or will increase the flow rate of the fluid using centrifugal force. Different pumps can be used for different places and usages, for example, there are Slurry Pump, Dredge Pump, Gravel Pump, Froth Pump, Sump Pump and so on. And they are always equipped with other Pump Parts to get a expected effect.

Описание: ctri-eng.com Threaded fasteners are often used in conjunction with a threaded insert to join two or more objects. Also known as threaded bushings, they provided female threaded to support the use of a fastener with male threading, such as a screw or bolt. The threaded insert is embedded inside an object, after which a screw or bolt can be driven into it. There are many different types of threading inserts like Threading Inserts for Oil and Gas Pipes and Indexable Standard Threading Inserts. All threaded inserts are designed with female threading to support the use of a fastener with male threading, but there are several different types of threaded inserts, each of which features a unique design. Helical threaded inserts, for example, are characterized by a coiled design, typically consisting of steel or bronze. The respective metal is coiled up in the precise size and shape to support the threaded fastener. There are also captive nut inserts, which consist of a nut wrapped around female threading. Also known as cage nuts, they feature “wings” on the top that dig into the object when a threaded fastener is driven into them. Captive nuts have been around for over a half-century, with the first patent being granted in 1946. Since then, they’ve become a common tool used for wall-mounting applications. Externally threaded inserts, as the name suggests, feature threading on the exterior. They still have internal threading, but they also have external threading. So, what’s the purpose of this external threading? With external threading, they can be driven into pre-drilled holes with greater ease. Threaded inserts are typically used when the object in which a threaded fastener is being installed is made of a soft material. For hard materials, a screw or bolt can be often driven into the object without the need for a threaded insert. For soft materials, however, driving a screw or bolt directly into the object can damage it. A simple solution is to use a threaded insert. The threaded insert is placed inside the object, after which the threaded fastener is driven into the insert.Another instance in which threaded fasteners are used is when an existing threaded hole is stripped. If the ridges of a threaded hole have degraded to the point where they no longer support or hold a threaded fastener, a threaded insert can be used. Finally, threaded inserts can be used when an object is too thin to support the full length of a threaded fastener. Some of the threaded insert may protrude out the back of the object, but a screw or bolt can still be driven all the way into it.Except for threading inserts, there are other tools may be used for drilling and other industory production, such as Deep Hole Drilling Tools including Profile Cutters and Cermet forming Inserts, Cermet Profile Cutting Tools, Special Profile Inserts, Ultral Hard Cutting Tools and Cutting Tools for Tubes.

Описание: corrugatedplasticproduct.com Corrugated plastic sheets has become one of the most sought after products in the industries worldwide. Corrugated plastic sheets also known as Corrugated Plastic Cardboard, Coroplast sheets , Waterproof Cardboard, Corrugated Stratocore sheets. This is mainly because of the various usage corrugated plastic sheets hold on different platforms and workplace. From factory sheds to sign boards, street directions to roofing alternatives, there is a host of alternatives corrugated sheets can address. Corrugated plastic sheets are very strong due to the combination of two layers held by a ribbon center in between. This structure makes them known as twinwall plastic sheet. The dynamic value of corrugated sheets hold significance in its usage because of the property of polypropylene and polyethylene which are versatile thermoplastics. Polypropylene is resistant to many chemicals at normal temperatures and can provide extra resistance from UV, harsh weather, static load and fire. Its propensity to adhere to climatic changes and unforeseen hardships is indeed an advantage. Many warehousing industries have been using PVC corrugated plastics reinforced with chopped glass fiber for their storage cabins. ASA, PVC and polycarbonates have become synonymous with longevity. One can find them commonly being used in the roof construction also. There are different types of corrugated plastic sheet made of different materials like PP Corrugated Plastic Sheet and PE Corrugated Plastic Sheet. Uses of Corrugated Plastic sheet:The use of Corrugated plastic sheet has significantly firmed up its holding to the industrial sector. Let's discuss some of the clear uses that can be derived from corrugated plastic sheets and know how they hold true dynamism in today's era: Building architecture: Corrugated plastic sheets give ideal protection against storms and heavy winds because they can withstand air pressures almost 200 times stronger than glass and they are easily installable because they are 5 times lighter than plywood. There is no repainting required and the material does not soil or rot. Dust cover: Newer building constructions are covered to contain dust and fumes emanating from debris arising from house revamping. Large corrugated boards work as excellent trapdoors to contain the grits from falling to the neighbor's premises. They also work as a security fence to avoid unrestricted entry. Roofing structure: Clear polycarbonate corrugated sheet is an excellent source of translucent roofing sunrooms which relay sunlight to the room during the day. Corrugated sheets are rigid and also lightweight. They have good insulating properties. They are also extensively used in greenhouse applications and small structures requiring a sturdy construct. Packaging: Corrugated plastic sheets are favorable to make into a perfect packaging material. Henceforth their strength, durability and soil resistance makes them an easy alternative to paperboards and wooden package material. Comparatively, they are cheap to afford and don't tear off but can be easily cut through a knife. Many grocery stores, book sellers, distillers, gift sellers use corrugated boxes for packing different materials. What's more, corrugated plastic can be used not only as corrugated plastic sheet, but many other products like Plastic Pad, Plastic Protection Sheet, Plastic Sign, Corrugated Plastic Box, Corrugated Plastic Packing Box, Corrugated Plastic Tray, Corrugated Plastic Bin, etc.

Описание: chinacapmachine.com Bottle Cap Machines can be manufactured in several different ways to handle the cap and bottle combination to be used on a packaging line. Of course, almost any capping machine can be built to run production semi-automatically or automatically. But different machines will also be built to handle different types of caps, from screw caps to snap on caps and ROPP caps. The operation of each type of Cap Compression Machine will differ as to the method used to tighten or seal the closures. The Auxiliary Equipment like spindle capper is probably the most popular automatic capping machine for screw type caps. This capper receives bottles with caps already set in place and then automatically tightens the caps using several sets of matched spinning disks, or spindle wheels. The capping process will run continuously without bottles stopping for indexing, cap placement or any other reason. Of course, in order to remain consistent and reliable, the spindle capper must stabilize the bottle as it passes through the disks that will spin down the screw cap. Gripper side belts and cap stabilizers hold the caps and bottles in place as they move through the capping machine. The gripper belts will be used on the side of the bottle to keep it upright and in position during the capping process. Some applications will require a capping machine with double gripper belts to keep tall or odd shaped bottles stabilized. The cap stabilizer will keep pressure on the top of the cap from placement on the bottle to (at least) the point where the bottle and cap are introduced to the spindle wheels. Most spindle cappers will use three or four sets of spindle wheels to tighten down the caps. The last set of spindles will normally include clutches that allow for just the right amount of torque to create a dependable seal on the bottle. As noted above, the bottles run continuously through the capping machine. This is made possible on the automatic machine through the use of a sorting elevator or sorting bowl that will automatically deliver Plastic Caps to the capping machine. The automatic cap delivery system means that the operator of the capping machine or packaging line need only replenish bulk caps on occasion. Changeover on the capping machine will normally consist of simple hand adjustments to the cap chute, the height and width of the spindle wheels and gripper belts and some adjustment to the elevator or bowl. In some cases, where a wide variety of caps are being run on one machine, some tool based changes may be necessary, such as changing out a stabilizer or adding a second gripper belt.The spindle capping machine will work with numerous types of screw caps as well. From simple flat caps to sports caps to trigger sprayers and other unique screw type caps, this capping machine offers both versatility and efficiency for a wide range of industries

Описание: allsuspensions.com 4WD'S are among the most modified vehicles due to their flexibility and wide range of uses. From roll cages for those who use their 4WD'S to take part in races, to front bull bars that protect the radiator and the engine from high impact, there are dozens of modifications and accessories you can add to your all-terrain vehicle. One particular and popular modification to an 4WD is the add on of suspension lift kits. In this article we will focus on the suspension lift kit and its benefits. And the Lift Kits can be devided into different types according to different parts they may used for, such as Leveling Kits, Body Lift Kits, Lowering Kits and so on. The suspension lift kit is a modification done to an 4WD to raise the overall height and obtain extra inches of ground clearance. This helps the vehicle's off-road performance by avoiding the obstacles that can be found on the ground. Other advantages include a steeper approach and the possibility to accommodate larger wheels and tyres. A Lift kit is practically a kit that contains the parts needed to lift a specific vehicle model, and instructions on how to do so as well. The contents of the package depend on the model – some kits only contain parts that are difficult to obtain otherwise (generic hardware can be used to complete the lift), while others include a variety of parts, like new suspension, drivetrain parts, drive shafts, etc. Except for lift kit, there are other tools important for a vehicle. Shock absorber is definititely one of them. A shock absorber or damper is a mechanical or hydraulic device used to absorb and damp shock impulses. This is done by converting the kinetic energy of the shock into another form of energy (typically heat), which is then dissipated. Most shock absorbers are some sort of dashpot (a damper that resists motion by viscous friction). Along with smoothening out bumps and vibrations, the key role of the shock absorber is to ensure that the vehicle’s tyres remain in contact with the road surface at all times, which ensures the safest control and braking response from your car. Shock absorbers essentially do two things. Shock absorbers not only control the movement of springs and suspension but also keep your tires in contact with the ground at all times. At rest or in motion, the bottom of your tires is the only part of your vehicle that comes into contact with the road. Any time that a tyre's contact with the ground is broken or reduced, your ability to drive, steer and brake is severely compromised. The shock absorbers dampen the movement of the springs by converting the spring's kinetic energy into thermal (heat) energy. Shock absorbers are oil-filled cylinders. When your vehicle's suspension moves, a piston moves up and down through the oil-filled cylinder. And besides, there are many other tools may be used like Wheel Spacers, Suspension Arms, Performance Control Arm, Subframe Braces, etc.

What Happens If I Put Raw Gas in a Chainsaw?
Описание: What Happens If I Put Raw Gas in a Chainsaw? Chainsaw engines require a premixed fuel to keep them running at the proper temperatures. The oil that's added to the fuel lubricates the piston and crankshaft, but it also keeps the engine cool enough to keep running. Without this oil in the gasoline, the piston will seize and the engine will be ruined. With the regular mixed fuel, the oil keeps the piston lubricated inside the cylinder. The piston moves up and down at incredibly high rates of speed. The crankshaft also turns at these same speeds. This high rate of speed causes enormous friction to build and heat up these engine parts. The oil, however, keeps these parts just cool enough to keep running. If no oil is present in the gas, the fuel will still ignite and power the piston and crankcase. However, the fuel will burn at higher temperatures, resulting in piston failure. Without the oil to keep the fuel from burning at a high temperature, the piston will seize up. The metal on the cylinder and the piston will heat and expand to the point where the piston no longer fluidly moves up and down inside the cylinder. This will cause friction inside the cylinder, eventually causing the piston to freeze up or stop moving completely. This will also cause the crankcase to stop turning underneath the piston. When the crankcase stops moving, all other systems shut down instantly. Most often, if straight gas is burned inside the engine, the engine is ruined. Little, if nothing, can be done to fix this error. The seized piston can't move, and the crankcase can't turn. While the piston and cylinder may be able to be removed and replaced, it is usually unlikely, as the metal will have heated up and burned out all other parts within the piston and crankcase. These systems are difficult to reach and costly to fix. Often, a new chainsaw will cost less than trying to fix the seized piston, which may not even guarantee it will work again. If you've put straight gas in the fuel tank, don't start the engine. If straight gas is used, it can damage and ruin the piston and crankcase within a minute, as the gas doesn't take long to burn out these sensitive parts. Drain the tank immediately into a separate fuel container. Pour approximately 1 tsp. of clean water into the tank, swirl it around and dump it out. Change the fuel lines and, if possible, remove the carburetor and clean it to prevent any unmixed gas from entering the cylinder. The Best Mini Chainsaws for Landscaping and Lawn Care Mini chainsaws are great for powering through light-duty lumberjacking projects, like pruning branches and cutting small logs. Their rugged design and powerful motors pack a serious amount of cutting power into a small package, and offer a durability that users typically won’t find in other power saws. They’re not great for precision cuts, but if you’re looking for a tool to quickly and effectively chew through wood, one of these tools will have you covered. Chainsaws—regardless of their size—require substantial control by the user to be operated safely, so if this is your first chainsaw, take the time to thoroughly review the instruction manual. When choosing a mini chainsaw, take the time to consider what you’ll be using it for. Most importantly, are you going to be pruning trees or bushes that would otherwise require you to get on a ladder to reach? In that case, we would definitely recommend opting for one of the options that include a pole attachment, allowing you to reach high branches while remaining safely on the ground. If you don’t want to worry about wrangling extension cords or hunting for outlets while you work, you’ll probably want to opt for a battery-powered option. If you’re short on storage space, you may want to go for an extra-compact, one-handed model. We have years of experience using a variety of chainsaws, large and small, through our time spent as a landscaper as well as for at-home projects. This experience, combined with extensive online research, helped us curate this list of mini chainsaw options. Most users will probably only need their chainsaw for occasional projects, but for those who plan on using their saw more frequently, and for heavier-duty jobs, we made sure to include a commercial-grade option as well. We also did our best to include a range of styles and sizes, from tiny 4-inch blades, to larger 10-inch options. Can You Efficiently Strim (and Cut) Wet Grass and Should You Be Doing it at All? The rain keeps pouring seemingly without end and your lawn is now soaked. For the first time in days, however, the sun makes its way through the crowd of clouds. This is your opportunity – you’re about to mow the tall neglected grass in your yard… But should you? So, if you: Need to mow your lawn during or right after a rainy period; Are wondering if it’s safe; Want to know how to do it properly, Then read on! This article will help you. Strimming after rain may become tricky because of the soggy grass, so you start asking yourself questions. Will the damp lawn be kind to your string trimmer? What about mower blades, will they be as efficient this time around? Is it safe to cut the grass when wet at all if you own electrical equipment? Let us explain. When the grass is wet, it will become heavy and sticky. The blades (or lines) of your tool of choice should either be freshly sharpened or brand new. Otherwise, they will have troubles with cutting an even lawn level. There are a few situations when you can (and should) strim wet grass: Only strim a wet lawn if the rainy weather doesn’t allow it to completely dry out. When working, frequently check if the tool is clogged. There’s a chance that your strimmer will chew up, knock over or even miss the taller wet grass blades altogether. When the ground dries out afterwards, the bent over sod will straighten up. To avoid an uneven lawn cut trim repeatedly. Consider this: You will lose the benefit of evenly spread fresh grass mulch. Wet clippings will stick together forming clumps. These clumps, if not raked, may damage some of the grass patches by suffocating them and depriving them of sunlight. What is the difference between a hedge trimmer and a hedge cutter? Well-rounded gardeners should be familiar with both hedge trimmers and hedge cutters. If your space has any kind of hedge-type plant, you’ll be using one of those tools to keep them tamed and manicured. However, a lot of people are unaware of the distinction between the two. Most people, even many gardeners, think that hedge trimmers and cutters are one and the same. While they may seem like they can do similar tasks, trimmers and cutters have their own strengths and weaknesses when it comes to maintaining the look that you want for your hedges. Whether you’ve already got a green thumb or you’re just getting into gardening, it’s handy to know this type of thing. If you didn’t know there was a difference between hedge cutters and trimmers before and want to get informed on what separates the two, you’ve come to the right place. Hedges can be used for many things, such as plant art, as perfectly-coiffed sentries marking a path or as a sort of plant-fence. Hedges are a perfect way to mark off the edges of your space without ruining the aura of your garden with an ugly wooden fence. Not to mention that hedges help to keep little critters out of your precious plot. While hedge cutters and trimmers are two different tools, they do share some things in common. Both cutters and trimmers can come with a variety of power sources. The three most common are described in detail below: Electric – These kinds of trimmers and cutters are a great way to ease up the tension on your shear-wielding hand. You will have to do a lot less work than if you were going manual but they can usually only cut through quarter- to half-inch thick hedges. While they’re much lighter than gas cutters which makes them easier to work with, their lack of power also means that they don’t bother with as many safety features either. Gas – Cutters and trimmers powered by gas are much more powerful than their electric-powered counterparts. Most gas-powered cutters can cut through three-quarter-inch thick hedges, and sometimes even branches that are a full inch thick. They also offer more strokes per minute and they have much better blade gaps that allow you to get the job done faster and more efficiently. If you’ve got a hefty amount of work to do on a large property, gas-powered cutters are usually the smart bet. While they are heavier and more powerful than electric cutters, which makes them a bit more dangerous, they also often come with a tip guard. The tip guard protects the tip of the saw from touching any body parts, greatly reducing the injury risk. Cordless (Battery-powered) – These are probably the overall safest type of hedge cutter and trimmer but they’re usually not a whole lot better than going at it manually. These are often the cheaper option and they give you the added bonus of avoiding all the wiring that comes with the other two options. They simply take longer to do the job and they require full charges before doing any significant work

Tools Your Print Provider Should Be Using
Описание: Tools Your Print Provider Should Be Using The printing industry has radically changed over the years. In order to continue to produce high quality projects there are certain tools that are invaluable to a printer. Here at Hackworth, we utilize these tools to help businesses with professional level print work. Here are five tools of the printing industry that provide the best possible results for clients. The digital printer is a fast and productive tool that also prints great quality. It is the most common type of printer in the printing industry. Unlike traditional printers, the digital printer does not have plates that you need to swap out, and it can function much more independently and precisely at the same time. It has also proliferated capabilities such as print-on-demand, short turnaround time, image modification and allowed the use of different designs across the same print job. While many printing jobs utilize a standard letter or a legal size, and sometimes even smaller, other projects require larger output. For jobs such as posters, flyers, banners, wallpapers and vehicle wraps a printer that can handle large rolls of paper is necessary. The wide format printer does that job. This printer most commonly uses some variant of inkjet or toner-based technology to produce a printed image. It is more economical compared to other printing methods such as screen printing. Without a wide format printer, it would be impractical to create large banners, posters, signs, etc. However, with these machines, you can print these types of projects very easily. Also, you have the option of printing them in sections to assemble them later. Flatbed printer, typically used for commercial purposes, is characterized by a flat surface where a material is placed on top to be printed on. It is capable of printing on a wide variety of materials such as photographic paper, film, cloth, plastic, acrylic, glass, ceramic, metal, wood, leather, and many more. A flatbed printer uses UV curable inks that are made of acrylic monomers which will then be exposed to strong UV-light to cure them. In that way, printing on wood or canvas carpet, tile, and even glass is made possible. The flatbed printer, although limited only to flat materials, is a versatile tool that could produce the most creative and unique materials. These tools, perhaps, are the most overlooked part of the printing businesses. With all the technology now available, computers are updated and upgraded so often that a 1-month old computer can become obsolete! However, when the correct technology is purchased this problem can be avoided. Another requirement is high quality HD monitor to see every aspect of the graphics and images on screen. This is necessary to avoid wasted material on test prints, color proofing, resolution and sharpness. Another thing to consider is computer software. In our company, we make use of the Adobe Suite such as the Adobe Illustrator, Adobe Photoshop, and Adobe InDesign, which are industry standards. They produce the best results with their complex yet very detailed tools that make designing and printing projects possible. Flexo vs. digital printing: Which technology is better for your brand’s labels?There isn’t a clear-cut answer to this question. In fact, “versus” is the wrong word to use when comparing digital and flexographic label printing; neither technology is inherently better or worse than the other. Which press technology makes the most sense for a particular job will depend on a host of brand-specific factors, including run size, promotional opportunities, lead time, design complexity and more. And because there are so many factors to consider, there’s no quick rule of thumb you can reference: “If X, then digital is the best technology for your brand. But if Y, then flexo is the better choice.” So, with no simple answer to this question, how do brands choose? Well, it requires a conversation with a label converter. And not just any label converter — one that has experience printing millions of labels on both digital and flexo presses. Converters with the capability to print with either technology will give you an unbiased take on which is best suited for your brand’s unique needs. And while there’s no substitute for a conversation with your converter, in this article, we’ll walk you through the basics of each technology, and certain scenarios in which each might be “better” for your brand. How To Start Paper Bag Making Business With the rising toxicity and pollution levels in the environment, eco-friendly products have become the need of the hour. The governments and various companies across the world are finally discouraging the use of plastics which causes disastrous environmental issues. This has paved way for paper bag making businesses. Paper bags are in great demand nowadays for their recyclable and sustainable features in nearly every commences activity. Gift packaging Market potential and opportunitiesPaper has no real competing product. Plastic bags, once regarded as a substitute for paper bags have lost their market over time. Moreover, the establishment of consumer stores and shopping malls has further increased the demand for paper bags. Hence, the paper bag making business is a booming opportunity for new and aspiring entrepreneurs. As paper bag making is generally a small-scale business, it will require minimal investment. The main areas of investment will be the cost of machinery, labor, and land. Maintenance, transportation, and marketing will contribute to variable investments. The price of one fully automatic paper bag making machine is around 5 – 8 Lakhs INR. The price is dependent on the production capacity of the machine. One fully automatic machine can produce 15000 pieces/hour. Researching and proper planning as to where to spend and the choice of suppliers will also reduce your cost to a significant extent. How are Plastic Bags Made? We use a lot of plastic bags in the world today. In fact, nearly 1 trillion of them are created every single year. Plastic bags can be found in many different places and have a versatile mix of uses, from carrying books to separating items to carrying groceries and all in between. Plastic bags are popular for a number of reasons and can be customized for any company or product. Some are very cheap and can be used for so many different purposes. And, despite what many people think, plastic bags can also be recycled and reused a number of times. Creating polyethylene bags can be a simple process, which is one of the reasons that they are so popular. Of course the process of creating the plastic bags is one that must be completed in a shop that has the right equipment, however, despite this fact, the bags are easy to make. To create a plastic bag, the process is similar to the process for creating a book. Both are very easy to create, but the plastic bag is far easier to create than a book. A company must have special equipment to create the bag, however, there are just two steps required to make the bags.A process called extrusion is the first step in making a plastic bag. An extruder is used to heat the polyethylene plastic to a temperature of about 500 degrees F. This temperature will melt the pellets, at which time the molten plastic is pushed into the machine and a die that determines the thickness that the bag will have. After this happens, the plastic film is pushed into a bubble by the outside air and through a cooling process. Next, the film is cut into the appropriate size and then placed onto a spindle. Once the plastic bag is placed onto the spindle, it is sent to what is known as a conversion department. This team unwraps the film roll and cuts it with a heated knife that also seals each of the sides of the bags together. Once this is completed, the conversion also adds all of the special characters of the bag. Next, handles are cut out using a heat process, and logos, designs and text is added to the bag. Creating Plastic bags As you can see from the information above, creating plastic bags is a fairly simple and easy process that a company can do quickly and without a lot of trouble. Thousands of bags can be produced in only a minute of time, and since the process is so easy, it keeps the cost of the plastic bags down to an affordable price. The Bottom Line Plastic bags are very easy to create and they have so many different purposes that make them handy in our everyday lives. Now that you know how the bags are created you can feel so much better about using them! It is a process like none other. How Pouch Filling Machines Work Across the world and across industries, pouch filling machines are becoming more and more popular for industrial packaging. Pouches are flexible, lightweight bags that offer many advantages over traditional packaging such as metal cans or glass bottles.Pouch filling machines are usually of two types: vertical form fill seal (VFFS) and horizontal form fill seal (HFFS), with VFFS being the more preferred technology. Let’s see how VFFS packaging machines work. A vertical form fill seal machine is a kind of pouch making and filling machine with a vertical structure. It’s mainly used for industrial packaging and processing and provides a more convenient and effective way of automatic packaging, saving time, material wastage and cost. Understanding the main components of the VFFS pouch filling machine will explain how these machines work: Film Pulling System: This system consists of an unwinding roller and tensioner. A rollstock of film (usually laminated PE, PET, aluminium foil) is placed on the unwinding roller, usually situated at the rear of the machine. Using servo motors and the tensioner, the film is firmly and precisely unwound and pulled into the system. Printer (Optional): The film passes by the printer where the date, production batch code etc will be printed on the film. Pouch Former: After printing, the film moves to bag forming. The process overlaps the edges of the film to shape a pouch. Vertical and bottom sealing is done by sealing jaws. Filling & Sealing Machine: Filling is accomplished by connecting the bagging machine to multi-head scale or other filling machine, such as an auger or volumetric filler. Those two machines are synced electronically, so that as soon as the bag is ready, the product is dropped in automatically. Once the product has dropped into the bag, the top is sealed. The sealing jaws press the 2 parts of the overlapping material and weld them, often with heating, to create a side or centre seal. Pouch Cut: The filled and sealed bag is cut away. That top seal on the first bag becomes the bottom of the next bag, and the process repeats. The cut pouch falls to a collection system, typically a belt conveyor that brings the pouch to the next packaging step. Control Cabinet: On the side of the vertical form fill seal machine, is a control cabinet. It contains all the electrical parts inside. PLC, contactor, servo motors, pneumatic cylinder, solenoid valves, PLC expand mode, low-pressure electrical parts. HMI makes operating and controlling the machine easier. There are many pouch filling machine manufacturers offering multiple machines for diverse applications. Whether you are looking for an oil pouch packaging machine or searching for a reliable milk pouch packing machine manufacturer; whether you wish to package powder, liquid, viscous or granular products into flexible pouches – Nichrome is your best bet.

Why an electric tricycle for adults
Описание: Why an electric tricycle for adults An electric tricycle is an electric bike with three wheels that is equipped with an electric motor, also known as pedal support. A traditional tricycle has two parallel wheels at the back of the bicycle, but these can also be mounted at the front. The degree of (pedal) support can be chosen from different levels. This can help a person who can’t cycle that far without support. At Van Raam, we think that people who can stay mobile for a longer time are happier. We work every day to give people their mobility (back) and to enable them to cycle again, for example with an electric bicycle for adults or electric tricycles for kids. Read more about this in the article 'An adapted e tricycle from Van Raam'. Electric Van Raam bikes with the original Van Raam pedal support system can cycle backwards. In this way, the user doesn’t have to get off the bike, the bike can easily be taken out of the parking position and because you don’t have to walk backwards with the bike, you can’t hurt yourself by the wheels either. You can also find out how the lighting works via the Van Raam electrical system in our article 'Lighting via the Van Raam electrical system'. With the backwards cycling function it is possible to just turn around or park the bike easily. This makes the bike more agile and also safer. An electric tricycle has several advantages for the cyclist. With the help of the electric motor (or in other words the electric bike) you can withstand greater height differences or stronger headwinds, even though you are physically unable to move well or are less stable. Walking and cycling is healthy and is the least harmful to the environment compared to other means of transport. Especially for the elderly, cycling is often the most important way to go to sports, go shopping and see family and friends in every day life. Why cycling is healthy is explained in our article ‘10 reasons why cycling is healthy’ Besides the fact that cycling is healthy, it is also environmentally friendly and cheaper than the car or public transport. What’s more, you'll be on the road shorter and faster at your final destination. Cycling up to a distance of 5 kilometres is considered to be the fastest means of transport and in the city even up to 10 kilometres.We’ve written about the latest in cargo bikes, electric bikes, and artsy bikes created for design shows. But this electric walking bike made us do a double take. The Lopifit bike, by Dutch designer Bruin Bergmeester, is essentially a treadmill on a bike. A 350W Samsung lithium-Ion battery turns the treadmill while you walk, and the treadmill sits on a bike base that’s longer than usual. There’s also no seat—this is a walking-only affair. Bergmeester invented the bike four years ago; it recently began distribution in the U.S., Mexico, and the Caribbean. The battery generates enough power to get you 30-50 miles, a distance on par with many electric bikes used for commuting. And like a regular bike, riders choose the gear or speed they want, ranging from four to 17 miles per hour. According to Lopifit, this means that a person walking on the Lopifit will have speeds equal to or greater the other bike riders on the path. The design of the bike is striking, with multiple color options on a powder-coated-steel frame. A display on the handlebars shows you the status of your battery, and you can use the back rack for storage. Though we haven’t yet tested the Lopifit, a potential downside is its weight: It comes in at a hefty 125 pounds. There’s also the question of why exactly someone would prefer a treadmill-like walking bike over a regular bike—or simply walking. With a price of $2,495, it’s doubtful that the niche Lopifit will become a common sight on city streets. But, hey, for anyone who’s been dreaming of an electric walking bike—and you’re undoubtedly out there somewhere—this one’s for you. What's the Difference Between Lithium and Lithium-ion (Li-ion) Batteries? Batteries are an incredible resource of the modern-day, they power everything from cell phones, to wireless automatic vacuum cleaners, to all different types of cameras. There are numerous different varieties of battery which serve many different purposes, but two we hear about more than any are lithium and lithium-ion batteries. You might have had to make a decision in the past regarding these two different battery types, but do you really know what they are? To get the most out of your batteries, it’s a good idea to have some knowledge about Lithium and Lithium-ion batteries which come in all shapes and sizes like 95Wh batteries and 190Wh batteries. We’ll explain everything you need to know about Lithium batteries and their Lithium-ion cousins, including how they work, what they’re made from, and even how to recycle your old used batteries. Then, we’ll lay out the important differences between Lithium and Lithium-ion batteries, so you can make an informed decision about which to use. To understand the similarities and differences between Lithium and Lithium-ion batteries, you need a basic understanding of what constitutes a battery, and how they work. All batteries are made up of the same three basic components; the anode (negative - side), the cathode (positive + side), and some sort of electrolyte. When the cathode and anode of a battery are connected to an electrical circuit, a chemical reaction occurs between the anode and electrolyte. Electrons flow through the circuit from the anode, and then enter back through the cathode and prompt another chemical reaction. These reactions continue until the materials are consumed, at which point no more electricity is produced by the battery. Both Lithium and Lithium-ion batteries produce portable electricity in this manner and can be used to power all sorts of different devices and electrical circuits. Batteries are incredibly useful components that allow us all sorts of luxuries, without them we would have to start cars by hand, and phones would still all be attached to the wall. Lead-acid vs. Lithium Battery ComparisonLead-acid batteries cost less up front, but they have a shorter lifespan and require regular maintenance to keep them running properly. Lithium batteries are much more expensive up front, but they are maintenance-free and have a longer lifespan to match their higher price tag. This article offers a side-by-side comparison of both options. Welcome to our Solar 101 series! This article goes over a choice you’ll need to make if you buy a battery-based solar system, either to move off the grid or to add energy storage to your grid-connected home.Specifically, we’re going to look at lead-acid vs. lithium-ion batteries — the two main battery types used for solar. Here’s the summary: Lead-acid is a tried-and-true technology that costs less, but requires regular maintenance and doesn’t last as long. Lithium is a premium battery technology with a longer lifespan and higher efficiency, but you’ll pay more money for the boost in performance.Let’s go over the pros and cons of each option in more detail, and explain why you might choose one over the other for your system. Lead-acid vs. Lithium Solar Batteries: The Basics When you build a solar system, you have three main battery options: Flooded Lead-Acid (FLA) The distinguishing feature of FLA batteries is that the plates are submerged in water. These must be checked regularly and refilled every 1-3 months to keep them working properly. Falling behind on upkeep can shorten the life of the batteries and void the warranty. FLA batteries also need to be installed in a ventilated enclosure to allow battery gases to escape. Sealed Lead-Acid (SLA) SLA batteries come in two types, AGM (Absorbent Glass Mat) and Gel, which have many similar properties. They require little to no maintenance and are spill-proof. The key difference in AGM vs. gel batteries is that gel batteries tend to have lower charge rates and output. Gel batteries generally can’t handle as much charge current, which means they take longer to recharge and output less power. Benefits Of An Electric Motorbike Anyone who has been keeping up with the automobile industry knows that electric motorcycles are the way forward. Nearly all manufacturers are tinkering away at models that will create waves when launched. That doesn’t mean there aren’t already some worthy contenders on the market. One of the leading brands is Zero Motorcycles with a number of different models designed for different riding needs. We at Crossroads Powersports are your local electric motorcycle dealer in Upper Darby, PA and we know what are the many advantages of owning one of these machines! Read on to learn more and when you want to check out electric motorcycles for sale in Philadelphia, PA or Wilmington, DE, get in touch with us to see our wide inventory! 1. Environmentally-Friendly One of the main advantages of electric motorcycles is the fact that they use limited non-renewable fuel and don’t pump out a lot of harmful emissions. These bikes are designed to go easier on the environment and reduce your carbon footprint. Newer models will have recyclable batteries and the option to charge from a renewable power source, like the solar power source in your home. 2. Less Expenditure Currently, electric motorcycles have higher sticker prices than their gas counterparts but they are more cost-effective in the long run. You’ll obviously save a lot of money by not needing fuel fill-ups. Apart from this, some governments are working to provide special incentive programs on their purchase price and taxes. If you have a renewable source of power, your savings will be even higher. 3. Easy Daily Commuting These bikes are often more lightweight and easier to ride, so you reach your destination feeling upbeat instead of being tired and sweaty. It’s also much easier to park these sleek beasts and zip through traffic instead of waiting around. Electric motorcycles are designed with regenerative braking, which means they’ll recharge the battery while you drive around to your heart’s content. 4. Less Noise Some riders will talk about how much they love the roar of their bikes, but you have to admit that it can increase noise pollution and even end up annoying your neighbors and fellow commuters. If you like to listen to soft music as your ride, you can’t do that with a traditional model. Electric motorcycles are so quiet that some manufacturers actually add artificial sound to them just so others can hear you coming. 5. Low Maintenance Another awesome benefit of electric motorcycles is that they do away with components like air filters, spark plugs, oil, and sometimes even gearboxes and clutches. With fewer parts to repair and maintain, you spend less time and money on service and repairs. Even the brake pads on electric motorbikes last longer because the machine does a lot of the braking. That means you get more fun and less hassle from your new bike. 6. Instant Torque Electric vehicles are engineered to be fast. They hold the Pikes Peak hill climb record, not only for bikes, but also for cars! This is because of the instant 100% torque that provides rapid acceleration. The power delivery is so smooth and even that you don’t even get the surge feeling that you get when you accelerate on traditional bikes. 7. Good Health And Lifestyle When you ride an electric motorcycle, you have the option of switching between using the motor and pedaling. This is a good exercise and can help you stay in shape. You can pedal when you like and switch to the motor when you get tired. Running errands on electric bikes is cheaper, easier and faster than using your motorcycle or car. These are just some of the advantages of owning one of these vehicles. As manufacturers keep competing to outdo each other, this list is sure to grow! To find out more or to check out electric motorcycles for sale (including Zero motorcycles) in Upper Darby, PA, contact Crossroads Powersports and one of our friendly staff will gladly help you out. We’re proud to be the preferred electric motorcycle dealer for Philadelphia, PA and Wilmington, DE!

RABS versus Isolators
Описание: RABS versus Isolators Barrier Technology in Pharmaceutical Processing A major source of pollution in aseptic manufacturing is personal handling. Therefore, the reduction of human interventions in the critical zone leads to higher purity in the products. For aseptic manufacturing in pharmaceutical processing, Restricted Access Barrier Systems (RABS technology) as well as isolators offer improved sterility assurance for the product and an efficient protection of the staff against risks caused by hazardous substances. These aseptic barrier systems fulfill many applications in pharmaceutical production lines, such as finish manufacturing and packaging. Isolators include an automated bio-decontamination system and are suitable for long-lasting campaigns. A RABS, on the other hand, is an appealing solution for cleanrooms and guaranties the quality needs for applications which require more flexibility. If necessary, a RABS can be opened to allow for process intervention, while the Isolators must be kept closed during the entire operation. A major advantage of isolator technology over conventional cleanroom technology in aseptic environments is the high security level of protection of the product which is still not achievable with other methods working with aseptic products. A RABS provides separation by the barrier on the basis of a closed system for processing, which reduces the risk of contamination of the product because of reduced contact surfaces in comparison with handling in a normal cleanroom. In other words: It contains a barrier system with HEPA-filtered air flow, which allows a faster start and handling of processes compared with isolators and more flexible changes. Also, remodelling and renovations are cheaper. RABS air handling units operate similar to laminar flow fume hoods in a way that they get clean air from fan units through HEPA filters and the air vents from the unit into the RABS (overpressure airflow). Air exits through openings into the environment at a low level on the equipment. During operation, there should be no reason to open the RABS doors. If there is a severe cause to open the doors, the laminar air flow system and other elements must be able to prevent a collapse of the ISO 5 conditions. Each opening of the doors will be considered as a serious intervention and must be documented. An open RABS enables measurements and monitoring. RABS can – similar to an isolator – be driven as doors close system, with a very low risk of contamination. But a RABS contains not only a clean air maintenance system, it also includes an air lock zone, a well-designed equipment, laminar air flow, ISO 5 conditions in the critical zone, a quality system in place, SIP (sterilization in place), standard opterating procedures for interventions, disinfection plans and a documentation of all processes. An isolator is a closed system which has to perform two functions. It is a key control measure in preventing staff-exposure to cytotoxic substances, some of which may be carcinogens. It also has to protect the product from microbiological contamination during drug fabrication. Overpressured or underpressured isolators are enclosed units which rely on a steady flow of filtered air during use supplying ISO 5 conditions. Air entering and leaving the isolator will do so through HEPA filters. Access to an isolator is performed through glove ports and sterile transfer systems. Isolators can work in an ISO 5 to ISO 8 environment. Cleaning can be done manually or automated. Bio-decontamination of the isolator occurs through an automated cycle with H2O2 decontamination. Should there be a leak of the isolator, the system is not airtight. For an overpressure system, the leak will allow air, which might be contaminated with cytotoxic substances, to enter the workplace. For a negative pressure system, air that may contain bacteria could enter the isolator and contaminate the preparation. A good leak detection system should therefore be in place in order to ensure that the leak is identified by once. It is included in an environmental monitoring system with built-in sampling ports. Understanding Closed-System Transfer Devices: Why They Are Important and How to Select an Appropriate System CLOSED-SYSTEM TRANSFER DEVICES, OR CSTDS, are defined by the National Institute for Occupational Safety and Health (NIOSH) as, “A drug transfer device that mechanically prohibits the transfer of environmental contaminants into the system and the escape of hazardous drug or vapor concentrations outside the system.” These systems are important in protecting health care professionals from exposure to potentially cytotoxic and teratogenic medications both during product preparation and administration.1The Importance of CSTDs in Protecting Health Care Professionals CSTDs help protect health care professionals from hazardous drugs, including pharmacists preparing medications and nurses administering medication. It has been estimated that 8 million health care professionals are exposed to hazardous drugs each year, increasing the risk of chromosomal abnormalities, teratogenicity, and cancer. More than 100 studies substantiate the increased risk, and more than 50 studies have documented harm to health care workers as a result of exposure.2-4 In a 1999 study published in the Journal of Occupational and Environmental Medicine, Valanis and colleagues analyzed pregnancy outcomes in nearly 3000 nurses, pharmacists, and pharmacy technicians and compared those outcomes with those in more than 4000 women who were not health care workers. In health care workers, spontaneous abortion or stillbirth was 40% more likely (OR 1.4; 95% CI, 1.2-1.7) to occur in individuals who reported handling hazardous drugs.5 In 2010, McDiarmid and colleagues published a study in the Journal of Occupational and Environmental Medicine identifying a higher rate of chromosome 5 and 7 abnormalities among health care workers frequently handling antineoplastic medications than in health care workers who handled such medications less frequently. Researchers collected blood samples from more than 100 health care workers and analyzed the likelihood of chromosomal abnormalities related to the frequency of hazardous drug handling in each individual. Findings indicated significantly higher rates of structural chromosomal abnormalities in a high-exposure subset of health care workers than in a low-exposure group (0.18/person vs 0.02/person, respectively; P = .04). Significant outcomes included a 24% greater risk of chromosome 5 abnormalities (P = .01) and a 20% greater risk of chromosome 5 or 7 abnormalities (P = .01) in high-exposure individuals.6 These studies are not merely an academic exercise. Exposure to hazardous drugs has real-world consequences. Before she died of pancreatic cancer, pharmacist and hazardous drug compounding advocate Sue Crump reported, “One of my friends after another was coming down with either some very rare, exotic, bizarre disease; brain tumors; sarcoidosis; arrhythmias; or cancer.” When Sue developed pancreatic cancer at the age of 55 after a 23-year career in oncology pharmacy practice, she turned to the media and drew attention to the issue of inadequate protective controls in hazardous drug compounding.7 Sue’s case did not occur in isolation. Pharmacist Bruce Harrison, veterinarian Brett Cordes, and nurse Sally Giles all eventually developed cancer or precancerous conditions in their fourth or fifth decade of life after being exposed to the occupational risk of hazardous drug handling. Sadly, Bruce Harrison, who had a key role in developing hazardous drug handling guidelines, died at the age of 59. Sally Giles died of bile duct cancer in 1992. Brett Cordes has since recovered from cancer, but has left private practice to advocate for improved compounding safety standards.7 Use of CSTDs can help protect health care workers from exposure to hazardous medications. However, when considering a CSTD, it is important to understand that this set of products have very different design characteristics and, with regard to protective efficacy, some products have been studied extensively with high-quality trials—and others have not. What exactly is the difference between Sterilisation and Disinfection? At Sychem, we are specialists in Disinfection, Sterilisation and decontamination, and operate in a wide range of industries. Despite many people using the terms Sterilisation and Disinfection interchangeably, there are significant differences between both types of high-level cleaning. What exactly is the difference between Sterilisation and Disinfection? Cleaning & Disinfection: A process that removes dirt, dust, large numbers of microorganisms and organic matter, killing most, but not all viable organisms.Sterilisation: This is a process of removing or killing all viable organisms including spores. Dead microorganisms and toxins (pyrogens) may remain. Decontamination: A process that destroys or removes all microbial contamination to render an item or the environment completely safe. The process of Disinfection is used to reduce the number of viable micro-organisms on a device, but it is not guaranteed to inactivate them all. Disinfection can be used to reduce the number of viable micro-organisms down to a level that ensures the device is fit for its intended purpose. A reduction in the number of viable micro-organisms to the most minute number via cleaning and Disinfection makes a device sterile. In comparison, sterilisation is a process designed to kill all types of micro-organisms, including viruses, bacteria, and resistant bacterial spores, but is not necessarily effective against prions. This is because it is simply not possible to detect all organisms on a device. The term sterile can be used when the potential bio-burden (the number of organisms on a device) has been reduced such that there is less than one in a million chance of any surviving. How To Compare Different Types Of Gloves In Terms Of Thickness, Quality And Strength However, when comparing all the different types of hand protection, it can be hard to tell the difference and find the best fit for your purpose. Furthermore, most hand protection companies don’t explain all the complex variables that go into the creation of a glove. They use industry jargon and expect you to know what they are talking about. The Glove Company wants to clear the air around gloves and hand protection. We will explain the industry jargon and provide you with a helpful guide to remember when trying to find the best gloves for your needs. Every situation and glove is different though, so if you have the smallest amount of doubt that the glove you are using is not suited to your use, then please reach out to our Glove Experts, who are specially trained to find the best fit for every situation. Our hands can end up in all sorts of weird and hazardous situations throughout our lifetime. This means a glove that may suit your needs for one job will not provide adequate protection for another task.Furthermore, every company’s spec sheets and chemical-resistant sheets have different information on them, making it very hard to physically compare two different gloves. Generally speaking, in the safety industry, everyone automatically associates thickness with quality and strength. However, when it comes to gloves, especially disposable gloves, this is just not the case. Thickness can be an indicator but is not the principle driver.The thickness of a glove is not a reliable indicator of strength, quality, or puncture and chemical resistance. For disposable gloves in particular, it is easy to make a glove ‘thick’ however, if it’s made cheaply, or by someone who does not understand the complexities of glove manufacturing, the ‘thick’ glove will still easily snap or snag, when pulled or punctured. The only way to tell if a glove is of higher quality is to talk directly to a glove specialist and physically compare / trial the gloves. The best thing to do is call and have a chat to a Glove Expert, they will more than likely figure out which glove is the best for you, and then they will find the best way for you to trial the gloves. Most glove manufacturers are understanding of the fact that the best way for you to find the best protection is to talk to a specialist and trial the gloves, as every work, task or job is different. Once you get your hands on the gloves, put them to the test, and it will quickly become apparent, which is the better glove. Physically comparing and testing gloves is the best way to find the perfect fit for you. However, sometimes, you may need to compare gloves using technical specs and /or certifications. If you do, there are a few glove expert insider tips and tricks that will enable you to make an accurate comparison. You can measure thickness in a variety of different ways. In America, they use mils (A “mil” is a unit of thickness equal to one-thousandth of an inch (.001 inch)). For the rest of the world, we use Micro Meters (Microns). A unit of length equal to one-millionth of a metre. It is important to note when measuring the thickness of a glove, that depending on which part of the glove is measured, there can be completely different results. For example, a thickness measurement taken from the fingertips will always be a lot thicker than a measurement taken on the palm of the glove. Best practice in the glove industry is to take the measurement from the palm of the glove. However, not everyone does, and this reason is partly why comparing gloves using only spec sheets does not work. You need to get your hands physically on the gloves and feel the difference for yourself. Membrane Filtration Method for Sterility Testing The Membrane Filtration Sterility Test is the method of choice for pharmaceutical products. An appropriate use of this test is for devices that contain a preservative and are bacteriostatic and fungistatic under the direct transfer method. With membrane filtration, the concept is that the microorganisms will collect onto the surface of a sub-micron pore size filter. This filter is segmented and transferred to appropriate media. The test media are fluid thioglycollate medium (FTM) and soybean casein digest medium (SCDM). FTM is selected based upon its ability to support the growth of anaerobic and aerobic microorganisms. SCDM is selected based upon its ability to support a wide range of aerobic bacteria and fungi (i.e., yeasts and molds). Incubation time is 14 days. This method is the method of choice for medical devices because the device is in direct contact with test media throughout the incubation period. Viable microorganisms that may remain in or on a product after sterilization have an ideal environment within which to grow and proliferate. This is especially true with damaged microorganisms where the damage is due to a sub-lethal sterilization process. All microorganisms have biological repair mechanisms that can take advantage of environmental conditions conducive to growth. The direct transfer method benefits these damaged microorganisms. The entire product should be immersed in test fluid. With large devices, patient contact areas should be immersed. Nova understands that appropriate modifications are required due to the size and shape of test samples. The method requires that the product be transferred to separate containers of both FTM and SCDM. The product is aseptically cut, or transferred whole, into the media containers. After being transferred, the samples are incubated for 14 days.
