How to use Pass-through Desiccators hood?

Among different laboratory equipments, storage equipments or furniture are considered as important or crucial for the laboratory. If you are searching for the high quality storage equipments, the pass through desiccators can be your choice. They are poised with excellent and safe storage in offering to various laboratory equipments and materials. In laboratories, different chemicals as well as instruments need storage in dry environment. For such storage solution, pass through desiccators are required. Using pass through desiccators has a lot of benefits in offering. Those benefits will be discussed below. Nevertheless, users must know how to use the Pass-through Desiccators. A complete guide for them in this regard has been provided.

Low Humidity Containers

Pass through desiccators are known as low humidity or no humidity containers. Many chemicals become waste when exposed to the humid conditions. Many laboratory apparatus or equipments can easily be damaged due to the humidity in atmosphere. Humid condition can cause rust formation on the iron based equipments or tools. Nevertheless, humidity can cause errors in experiments. Another notable point is that humidity can destroy the biological samples. In order to preserve those samples with perfection, low humidity containers are needed.

Different Types of Laboratory Desiccators

In laboratories, different kinds of desiccators can be found. For example, the commonest type of desiccators that were used in past is known as desiccant based desiccators. That means, a container which is considered as storage unit will be made humidity free with the help of desiccants. Generally, nitrogen gas is used as desiccants. However, many other desiccants are there. In modern days, vacuum desiccators have replaced the primitive ones. With the help of the vacuum desiccators, it is easier to make the environment inside desiccators completely humid free.

For different kinds of Desiccator Cabinet, different using manual has to be followed. These desiccators need proper maintenance as well. For maintenance, cleaning the containers is not just enough. There are a few more things that one needs to perform. To keep the container air tight, silicone grease has been used. This grease has to be applied on regular basis, though over application of the grease is not needed. It should be applied on regular interval with enough time gaps.

Maintenance and Safety for Desiccators

Proper maintenance and safety are important aspects of the modern desiccators. Safety is essential for many reasons. First of all, it is important for the safety of the chemicals, samples and equipments that have been stored inside the desiccators. Safety is crucial for overall safety of the laboratory equipments and the laboratory hall.

When you are using the pass through desiccators, you need to be careful on these crucial aspects. These desiccators are design to provide humid free environment to crucial laboratory equipments and materials. So, you need to have more than one desiccator for your laboratory for storage purpose. You should opt for high quality desiccators which come with excellent storage solution for you with perfection. Investing into high quality desiccators will make storage in laboratories simplified and convenient.

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.
