A 12 inch wide vacuum desiccator and hand pump allows you to create various vacuum jar experiments.
The economical hand operated air/vacuum pump is easy to operate. Each squeeze of the pump delivers approximately 15ml, and can be used to create vacuum of 15 mm Hg, or air pressure of about 2 atm (standard atmosphere). Pump features a gauge along with a removable cap and elastic valve to provide quick vacuum release without dismantling the pump from the line. Recommended for general laboratory use for applications that do not require high or precise vacuums.
Vacuum, White Base, PP/PC These autoclavable desiccators are made of polypropylene (PP) and polycarbonate (PC) and can hold a vacuum up to 740 mm Hg for 24 hours without any greasing. Autoclavable at 121°C for 15 minutes.
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 PP and includes a perforated PP desiccator plate. An internal groove on the flange holds the silicon rubber O-ring.
The PP stopcock accepts ¼" I.D. tubing and has a self-lubricating PTFE plug. Use the three-way plug to create a vacuum, release a vacuum, or for shut-off.
