Laboratory Desiccator

Desiccators are small enclosures which are used in laboratories to store the chemical substances in a dried environment preventing any reaction with moisture or humidity present in the air. It is made of heavy glass / polycarbonate and has two compartments in it. The lower one has a desiccant, which withdraws the moisture out of the air and keeps the desiccator dry. These desiccants could be anhydrous calcium chloride pellets or silica gel. The upper compartment keeps the substance which needs to be protected. A lid at the top closes the desiccator. Some enclosures use an additional vacuum stopcock for further evacuation of air. These are called vacuum desiccators.
