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.
