Desiccators, Space Saver Vacuum Desiccator

Great Alternative to Heavy Glass Desiccators
The unique shape offers maximum interior clearances for more or larger contents without further crowding the benchtop. The thick walls ensure a rugged shatter resistant unit that simply stores a vacuum or stays sealed even if not under vacuum. The included polypropylene stopcock has a vivid, red handle to immediately determine its orientation and a port that accepts 1/4" (6.4mm) I.D. vacuum tubing. The top section can be lifted off using the large ribbed knob at the top center. A Neoprene O-ring offers a secure seal, which does not require grease, but is unaffected if grease is applied. A rigid, perforated polypropylene plate, 3.2 mm (1/8") thick supports the contents and leaves space underneath for desiccant backup if desired. The plate is removable and can be replaced with High Heat Desiccator Plates (see Options below) to support hot crucibles. Replacement parts are available. Per each size.

• Lighter and less costly than similarly sized glass models; does not chip like glass
• Holds a full vacuum (29.9 inch Hg) at room temperature for 24 hours
• Tapered polypropylene stopcock with PTFE plug accepts tubing with ¼ to ?” I.D. and allows a controlled entrance of air preventing unnecessary turbulence
• 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)
• Flat Dome clear polycarbonate top with large ribbed knob maximizes interior clearances and provides an average of 13% greater interior volume over standard hemispherical domes
• Clear polycarbonate bottom models also offer increased viewing visibility from more angles
• All models include a 0.32cm (?") thick perforated plate; disposable or reusable desiccant can be placed on or under this plate
• White polypropylene bottom models can support incandescent crucibles on Minerit HD High Heat Ceramic Desiccator Plates
