A desiccator is an enclosed device that can be sealed and has desiccants to protect compounds from moisture. A laboratory vacuum desiccator cabinet has a desiccant or a substance that absorbs moisture, filling the space below the storage platform. A stopcock is included to allow the desiccator to be evacuated. A desiccator can be used for various purposes such as cooling heated substances in the desiccator to disallow moisture from gathering. The interior is dry because of the desiccating compound at the bottom. Chemicals that absorb moisture easily are stored in a desiccator, so their life is long. It is used for vacuum testing and degassing as well as defoaming.
A laboratory vacuum desiccator cabinet has a tight enclosure where gases are removed through a vacuum pump. This leads to a vacuum. A vacuum desiccator cabinet is also used for degassing, through which gases from compounds inside the cabinet are removed. Vacuum removes bulk and absorbed water from a substance. Heat along with vacuum can be effective as a drying method.
The features of a laboratory desiccator cabinet are:
• Two vacuum valves on for purging with nitrogen before vacuum is applied. This is only for vacuum desiccators;
• Perforated acrylic shelves for storing compounds;
• Vacuum gasket on the door for a tight seal for a vacuum desiccator;
• Removable cover (removable lid) to easily insert or take out samples; or
• The front hinged door can be opened to add or remove substances;
• Usually constructed with 1-inch thick and clear acrylic material.
Maintenance of the laboratory Stainless Steel Desiccator Cabinets
In order to maintain a laboratory Stainless Steel Desiccator Cabinets, regular checks and tests have to be carried out. These tests determine if the desiccator is performing its job well or not.
In case of vacuum desiccators, things like vacuum pumps and the vacuum valves will have to be checked to confirm if they are able to create a vacuum inside the cabinet. If they don’t work, then a drying agent will have to be added. The vacuum gasket is important for maintaining vacuum inside the cabinet to protect the compounds stored inside. A regular check that it’s working properly is necessary as well.
The most important element in a desiccator cabinet is
