Teflon® Vacuum Pumps
@

  • Resistant to corrosive chemical vapors

  • Will not consume or pollute drinking water

  • Ideal for rotary evaporation and gel drying

Designed for pumping corrosive gases such as acetone, acetic acid, benzene, methanol, or nitrogen oxides, without the need for cold traps, drinking water, or pump oil. Teflon® heads and Kalrez® wetted parts typically pure. Multi-port valves resist damage from liquids-no more inlet traps. Oil-free operation eliminates the need to contaminated oil. The heads are easily dissembled for cleaning with only a screwdriver.

Model 20975C includes a brass vacuum gauge, a fine thumbwheel control and a brass bleeder valve to allow instant and precise adjustment of the desired vacuum.
