These autoclavable desiccators are made of clear polycarbonate on top and can hold a vacuum up to 740mm Hg for 24 hours without any greasing. The top dome is molded in rigid, clear polycarbonate, giving a crystal-clear view of the sample. The knurled knob on the top provides easy handling of the dome. 94321 to 94324 have a transparent polycarbonate bottom providing increased viewing clarity. 94325 to 94328 have a white polypropylene bottom. An internal groove on the flange holds the silicon rubber O-ring. The desiccators also include a perforated polypropylene plate. The polypropylene stopcock has a self-lubricating PTFE plug, which opens to create a vacuum, closes to hold the vacuum, and opens again to release the vacuum.
