Desiccators cabinets or canisters are sealed to absorb moisture. Once a moisture-sensitive object is placed inside the desiccator with the desiccant (or drying agent), the object 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 in order to achieve lower humidity levels using a separate vacuum pump.
