Desiccators are sealable enclosures containing desiccants used for preserving moisture-sensitive items. Most common desiccators are circular and made of heavy glass. The lower compartment of the desiccator contains lumps of moisture absorbing material, such as silica gel. The substance needing desiccation is put in the upper compartment, usually on a glazed, perforated ceramic plate. The ground-glass rim of the desiccator lid must be greased with a thin layer of vacuum grease, petroleum jelly or other lubricant to ensure an airtight seal. A stopcock may be included to permit the desiccator to be evacuated. Such models are usually known as vacuum desiccators.
