Chemglass CG-4812-30 PTFE Diaphragm Vacuum Pump

The Chemglass series of all PTFE vacuum pumps are an excellent source of vacuum in the laboratory. They eliminate the concern about chemical attack to the pump or contamination of your pumped medium. Solid PTFE heads do not blister or peel, and advanced Kalrez® valves along with our unique PTFE coated, molded structure diaphragm provides the longest possible lifetime when pumping corrosive gases. They are perfect for use in rotary evaporation, vacuum distillation, vacuum filtration, gel drying or the transfer of corrosive gases. Using no house air or water for its operation, it conserves valuable resources and helps protect the environment by eliminating the disposal of solvent contaminated waste water or oil.
