The role of a pass through desiccator is very important in cleanrooms and labs. In fact in any laboratory where humidity and air pressure matters in production and environment control, there pass through desiccators must be used.

And they are common too. Two commonly used makes of pass-through desiccators are PVC made and Stainless Steel Desiccator Cabinets made.

Before you go for testing the performance of pass-through desiccators

Time to time testing of pass-through desiccators is important. If the instruments channelizing transfers between two rooms or compartments in a cleanroom does not gets tested for their ideal conditions, then items transferred may have altered humidity, or air leaking with them may alter environment of the compartment in cleanroom. To test the pass-throughs, you must first therefore know what exactly the instruments is supposed to help you at.

Why test pass-through desiccators

The role of the pass through Plastic Desiccator Cabinets is to give passage or channel between two different rooms or chambers, so that the air pressure, hygiene, and humidity levels of the controlled room stays the same and does not get altered due to multiple numbers of transfer of items inside and outside the room. There are two doors on either side of the instrument. When one door is opened to place an item inside the shelves of the storage box, then another door stay auto shut and can’t be opened. And when this door is closed, then only the door on the other side can be opened to take out the item. This functionality ensures total control in retaining the controlled settings of the cleanroom.
Therefore, if the pass-through desiccators has to be tested for right performance, then:

• The humidity of the item being transferred must be checked after transfer, and the humidity of the air inside the pass-through storage box must be checked.
• The doors must not open together. Hence the door lock must be checked. When one door stays open another should stay auto locked. No force should be able to open the another closed door in any way.
• There are gaskets on the doors to seal the doors air tight. From time to time these gaskets also need to be checked for their tightness.
• The SDPVC coating or portion of the door panels must be checked that they are intact. These panels reduce the threat and chances of electrostatic
• Look for any signs of corrosion or rust in a stainless steel pass-through desiccator.

When you check these things you actually check for the performance of the pass-through desiccator. However, you may need professional assistance in making all these checks.

Getting professional help

If you believe, you would need professional assistance to test the performance of any kind of pass-through desiccator you have, then you may call for testing professionals. They would come to the lab, test it, and give detailed report and certify it for being okay, or suggest needed repairs or replacements. This way also you may pass on the responsibility of testing to experts and stay sure that you are maintaining the optimum conditions in your cleanroom.

Important Equipments That You Must Store in Your Laboratory

A laboratory is such a place where important experiments are conducted. This is the reason why the place needs to be perfectly organized. There should various apparatus, elements, books and many other things. In a basic chemistry laboratory, we generally find a few equipments quite commonly. In the following section, a guide to those equipments will be provided. It is important to know about different accessories as well as equipments carefully. To create a perfect ambiance in the laboratory for working, it is important to get all the essential equipments at the right place. So, here are those laboratory equipments at a glance.

 

Safety Goggles

When you are working in laboratory, safety should be utmost priority, and there should not be any compromise on this regard. When it comes to safety equipments, we commonly go for the gloves for the hands, fire extinguisher, smoke detector and other safety gadgets. One of the most safety accessories that we generally miss out is the safety goggle. It is important to find good quality goggles for safety of the eyes. In chemistry laboratory, different kinds of researches or experiments are carried out with high reactive elements. These elements and gases can lead to permanent damages to the eyes. For example, ammonia in gaseous form can be dangerous for eyes. High concentrated acid splashes on the eyes can cause permanent damages.

Different Flasks for Storing Chemical Liquids

In order to store chemical liquids, flasks are used quite commonly. If you ask what are laboratory equipment and their uses, you should know about different flasks and their uses. For example, conical flasks are used for storing acidic substance. On the other hand, you shall find Florence flasks, which are also known as boiling flasks. This type of flask can be heated and the glass that is used for making the flasks comes with the power to deal with heating. It is to be noted that some flasks comes with caps. They should not be heated when the caps are closed. If they are required to be heated, only when the caps are open.

Funnels

For pouring liquids from one jar to another jar, you need funnels. This is basic laboratory equipment that you should have in store in your laboratory. Using funnels is important for two basic reasons. The first thing is that it gives convenience in pouring liquid from one jar to another jar. As a result, there is little loss of the chemical from the jar. The second important thing is that it does not cause any accidents. When pouring reactive chemical liquids, accidents may happen. That can be minimized by using funnels for the purpose of pouring liquid.

Thermometer

It is important to keep a thermometer for measuring temperature at the laboratory. This is a vital equipment or apparatus that you must keep in your laboratory. Using good quality thermometer is required, as sometimes measuring temperature of substances or liquids can be important for the purpose of research or experiment.

Apart from these crucial things, a few more apparatus or equipment’s such as Plastic Desiccator Cabinets, Glove boxes, flow hoods and many more are there. You should make a list of the equipments and keep them in store in your laboratory.
