## Description - Strong, shatterproof units provide dry storage and protection for sensitive products - Lighter and less costly than similarly sized glass models; do not chip like glass - Hold a full vacuum (29.9 in. Hg) at room temperature for 24 hours - Tapered polypropylene stopcock with PTFE plug accepts tubing with 1/4 in. to 3/8 in. 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 - All models include a 1/8 in. (0.32cm) thick perforated plate; disposable or reusable desiccant can be placed on or under this plate - Clear polycarbonate bottom models offer increased viewing visibility from more angles - Models with white polypropylene bottoms can support incandescent crucibles on Minerit HD High Heat Ceramic Desiccator Plates (available separately, F42038 series) - Models with clear polycarbonate bottoms offer increased visibility from more angles ## Specifications ||| | ------------ | ------------ | |Color|White| |Diameter (English) Plate|9.05 in.| |Diameter (Metric) Plate|23cm| |Material|Polypropylene bottom, Polycarbonate upper section| |Diameter (English) Inner|9.43 in.| |Height (English)|12.12 in.| |Diameter (English) Outer Flange|10.75 in.| |Diameter (Metric) Outer Flange|27.3cm| |Includes|Upper and lower sections, neoprene O-Ring, stopcock, 0.32cm thickness polypropylene perforated sample plate, tapered polypropylene stopcock with PTFE plug and red handle, flat dome clear polycarbonate top with large ribbed knob| |Product Type|Vacuum Desiccator| |Diameter (Metric) Inner|24cm| |Height (Metric)|31cm|
