What is a desiccator used for in the laboratory?
Desiccators are sealable enclosures containing desiccants used for preserving moisture-sensitive items such as cobalt chloride paper for another use. A common use for desiccators is to protect chemicals which are hygroscopic or which react with water from humidity.
What is vacuum desiccator?
Vacuum desiccators remove air and moisture with the use of an in-house laboratory vacuum or vacuum pump and can be brought back to vacuum easily after opening. Vacuum desiccators can also be used for degassing techniques.
What is desiccator cabinet?
A desiccator cabinet provides clean, dry storage to protect your sensitive materials from moisture exposure, ESD damage, and particle contamination. Portable desiccators, available in desiccant and gas-purge models, provide a compact storage solution that can be easily carried or stacked.
How do you make a desiccator?
A simple home desiccator can be made from an airtight resealable plastic bag and a hygroscopic drying agent like sodium hydroxide. Simply get a plastic container and fill it up with sodium hydroxide, then place it inside the bag along with a container of the chemical you intend to dry. Seal it up and wait.
How long does it take for a desiccator to work?

What is the difference between desiccator and desiccant?
is that desiccant is a substance (such as calcium oxide or silica gel) that is used as a drying agent because of its high affinity to water while desiccator is a closed glass vessel containing a desiccant (such as silica gel) used in laboratories for drying materials or for keeping them dry.
What is Super Dry desiccant used for?

What is drierite desiccant?
DRIERITE DESICCANTS DRIERITE is an all purpose drying agent for the efficient and rapid drying of air, industrial gases, refrigerants, organic liquids and solids.
How do you calibrate a desiccator?
To calibrate: Compare hygrometer to a known accurate hygrometer. Use a small screwdriver and turn the screw located on the back of the hygrometer dial until the display matches the accurate hygrometer. The calibration should be within ±6% RH of the accurate hygrometer.
