Base: polypropylene. Cover: transparent polycarbonate. Will hold a vacuum of 740 mm Hg for 24 hours, with loss not exceeding 20 mm Hg. The cover seals onto a neoprene O-ring set into the flange of the base to ensure a positive seal. Non-return valve (polycarbonate) and vacuum release tap (polyethylene) assembly included; a specially grooved stopper in this assembly allows air to be re-admitted very slowly to avoid disturbing the contents. A little grease spread on the O-ring will assist in establishing initial vacuum. The dessicator includes a removable pan for holding calcium chloride or other drying agents.
