The BÜCHI vacuum Pumps are chemically resistant PTFE diaphragm pumps, designed for use with all gases and vapours typically associated with the lab. The pumps are optimally suited for work with laboratory and industrial rotary evaporators as well as other typical laboratory instruments like drying ovens, vacuum centrifuges and for filtration purposes. The diaphragm pumps are positive displacement pumps, using a combination of the reciprocating action of a PTFE diaphragm and non-return check valves. The vacuum pumps can easily be upgraded to a regulated vacuum source by adding a vacuum controller. A secondary condenser on the exhaust side of the pumps can be added to reach a perfect solvent recovery.
