VACUUM PUMPS

Vacuum pumps are used to create and maintain a vacuum in a closed system; in order to handle samples, generate controlled experimental conditions, or to facilitate filtration, distillation and drying processes in the laboratory. Chemically resistant diaphragm pumps are oil-, maintenance- and contamination-free pumps providing quiet, clean operation in a wide range of applications, e.g., filtration, rotary evaporators, desiccators, degassing, solid phase extraction (SPE), suction of liquids in biochemistry, microbiology and tissue culture, drying of electrophoresis gels and vacuum ovens. They are often used instead of a water jet pump and therefore help save water and protect the environment. Rotary vane pumps are used whenever a negative pressure of up to 10-3 mbar is required, such as vacuum lines (Schlenk lines), glove boxes or freeze-drying.
