United Scientific Plastic Vacuum Desiccators - 55204
These autoclavable desiccators are made of polypropylene (PP) and polycarbonate (PC) and can hold a vacuum up to 740mm Hg for 24 hours without any greasing. Autoclavable at 120°C for 15 minutes.
The PP stopcock accepts ¼" ID tubing and has a self-lubricating PTFE plug. The three-way plug opens to create a vacuum, closes to hold a vacuum, and opens again to release a vacuum.
The top dome, molded in rigid and transparent PC, gives a crystal-clear view of the sample. The knurled knob on the top provides easy handling of the dome.
The lower part is made of opaque PP or transparent PC and includes a perforated PP desiccator plate. An internal groove on the flange holds the silicon rubber O-ring.
