Degas liquids quickly and easily in the laboratory or classroom with this small plastic vacuum desiccator. These strong, shatterproof units provide dry storage and protection for sensitive products. Lighter and less costly than similarly sized glass models they will not chip like glass and hold a full vacuum (29.9" Hg) at room temperature for 24 hours.
The tapered polypropylene stopcock with PTFE plug accepts tubing with ¼ to ?” I.D. and allows a controlled entrance of air preventing unnecessary turbulence. 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 units have a ‘Flat Dome,’ clear polycarbonate top with large ribbed knob that maximizes interior clearances and provides an average of 13% greater interior volume over standard hemispherical domes. They include a 0.32 cm (?") thick perforated plate under which disposable or reusable desiccant can be placed on or under. White polypropylene bottom models can support incandescent crucibles on Scienceware® High Heat Minerit HD Desiccator Plates. Clear polycarbonate bottom models offer increased viewing visibility from more angles.
