Bel-Art Space Saver Polycarbonate Vacuum Desiccator 420220000, 0.20 Cu. Ft., Clear Bottom, 1/PK

Space Saver Desiccators will hold a full vacuum (29.9" Hg 75.9cm) at room temperature for 24 hours and remain airtight even if not under vacuum. A polypropylene stopcock with PTFE plug accepts 6.4mm (1/4") I.D. tubing and allows a controlled entrance of air preventing unnecessary turbulence. The flat-top dome maximizes interior space while a neoprene O-ring assures a tight seal down to 0°C without the need for grease (ring will not be harmed if grease is used.) All models include a 0.32 cm (1/8") thick perforated plate.
