Vacuum Systems

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.

The Vacuum Pump V-300 is a chemically resistant PTFE diaphragm pump. The speed-controlled operation results in economical operation and very low noise emission. Thanks to the transparent front panel, contaminants are easily visible. It is optimally suited to work with the I-300 / I-300 Pro and R-300.

For industrial evaporation, there is the even more powerful Vacuum Pump V-600 available. More info
