Bel-Art 42020 Plastic Vacuum Desiccator, 190 mm Plate Size

Large interior volume -- The space saving design of the desiccator dome provides maximum interior clearances. They provide an average of 13% greater interior volume than standard hemispherical domes. Extra heavy walls -- Clear polycarbonate top and choice of white polypropylene or polycarbonate bottom. This strong, shatterproof desiccator will hold a full vacuum (29.9 (in) Hg [759mm]) at room temperature for 24 hours and will remain air tight even if not under vacuum. Featuring A polypropylene stopcock with a PTFE® TFR plug which turns, allowing a slow, gentle entrance of air preventing unnecessary turbulence and crucible damage. The stopcock handle is a highly visible red and has a port which accepts 1/4 (in) (6.4mm) I.D. tubing. A large ribbed knob at the top center for easy lifting. A Neoprene O-ring seal which does not require grease, but is not harmed if grease is used. A polypropylene plate 3.2 mm (1/8 (in)) thick with 3.2mm (1/8 (in)) diameter perforations for air transfer. The plate rests on the retaining ledge of the bottom section and has a center hole for easy removal. Choice of Bottom Section: Polypropylene provides excellent chemical resistance and permits the use of incandescent crucibles with standard size procelain plates. All clear Polycarbonate bottoms are available in the same sizes.
