Non vacuum desiccator cabinets are a common inclusion in most laboratories. The non-vacuum dry cabinets, as the name suggests are cabinets for desiccating, but are designed to be full of a gas or air, and not designed to be vacuum. Therefore all such cabinets which makes use of gaseous drying instead of vacuum drying are non-vacuum desiccator cabinets. The most common example in this are the nitrogen desiccator cabinets, which come in various designs, sizes, shapes, and builds.
Nitrogen desiccator cabinets
Nitrogen desiccator cabinets are the so called non-vacuum dry cabinets. Their purpose is to act as a desiccant. Desiccating is the process of keeping something dry by keeping moisture or water off the thing. These cabinets are designed such that they can maintain air inside or gas inside at a constant humidity without letting it get contaminated by outside air or moisture.
This way once nitrogen is inserted or clean dry air is inserted in these cabinets, they stay the same, clean and moisture free inside too, while keeping all items stored inside the cabinet dry too. That is how the process of desiccation is completed and maintained inside these cabinets. Thus the name desiccator cabinets or non-vacuum dry cabinets.
Why non-vacuum dry cabinets are used?
Non-vacuum dry cabinets are simply used to keep items store inside them dry. The purpose is to keep items, chemicals, and important things dry. There are many items that are used in a cleanroom under controlled conditions. Controlled pressure, temperature, moisture and many such things are maintained and observed in many important experiments and procedures. For these some items must be stored in extremely dry conditions, and no moisture can be allowed to react with them or affect them. Therefore if you have to maintain things with dryness for later use, you need a nitrogen purged desiccator cabinet.
Timely check for the non-vacuum dry cabinets
These dry cabinets need time to time care and cleaning. That’s why they get checked with all other lab equipments at regular intervals by professional engineers and technicians for their condition. Certified instruments and equipments in the lab can be used again and again, and can pass audits. That’s why such cabinets must get through evaluation checks at intervals to make sure for you that that are in the perfectly operable conditions to deliver accurate results in maintaining dryness of stored items.
The designs of the non-vacuum dry cabinets
Non-vacuum dry cabinets are made in various sizes and design. Some are designed with fixed shelves inside, while some don’t have shelves, and some have removable shelves. The shelves in most of the cases are perforated to allow the nitrogen or clean dry air to reach all parts of the interiors of the cabinet through those perforations. Glass, stainless steel, and acrylic are commonly used for making of these cabinets. To reduce chances of electrostatic charge growing inside due to extreme dryness, a preventive coating is applied inside the cabinet walls and door. Most cabinets have a transparent glass fitted door to help look inside clearly.
