Vacuum Desiccators
Above: 8-inch plastic vacuum desiccator
Vacuum Desiccator with stopcock, internal gasket, and perforated floor. Desiccant such as CaCl2 goes in the bottom, then polypropylene disc is put in place and containers to be dried are set on it. (Not intended for very hot containers).
Plastic desiccators are safer than glass for drawing vacuum, but they should still be used behind shielding in case of accidental implosion. At the very least, it's good lab practice to put a criss-cross of electrical tape strips on your desiccator.
Diameter of body approx. 8 inches, assembled height approx. 10 inches including knob. Diameter of perforated plate is about 7 1/2 inches (190 mm).
Features:
• Autoclavable!
• 3-way stopcock with self-lubricating PTFE plug
• Polypropylene body, Polycarbonate lid
• Can hold 740 mm vacuum (20 mm Hg absolute) for 24 hours. That's a vacuum of about 29.1 inches Hg (negative gauge).
$59.95 each
Never bump or move a vacuum desiccator when it's under vacuum pressure.
