Sterlitech stirrers and vacuum pumps are among the highest quality microbiology supplies of their kind. All of our vacuum filtration pumps you see here are piston-powered and oil-free and are available in a variety of ranges, including 110 and 220V, and PTFE.
While the Rocker series of vacuum pumps are not chemically resistant, the Chemker vacuum pumps are acid, alkali, and organic solution resistant and can be used for a wider variety of microbiology testing applications. The Gast continuous vacuum filtration pump can be used as both a continuous vacuum for filtration and as a positive pressure filtration pump.
