About Bel-Art Products 420250000 Bel-Art 42025 Plastic
Large interior volume -- the space saving design of the Desiccator dome provides maximum interior clearances. They provide an average of 13 percent 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" 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" (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") thick with 3.2mm (1/8") 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. Deep vacuum Desiccator features a polypropylene bottom and polycarbonate lid high crowned lid provides maximum interior clearance. Desiccator holds 29" Hg for 24 hours.
