Desiccant is used in specially-designed, sealable canisters or cabinets to absorb moisture. Once the moisture-sensitive object is placed inside the canister with the desiccant, it will remain dry. These canisters or cabinets are sometimes referred to as desiccant dryers or desiccant dehumidifiers. We offer both vacuum desiccators and nonvacuum desiccators. Vacuum desiccators usually have a built-in stopcock which allows the internal air to be evacuated to achieve lower humidity levels using a separate vacuum pump.
