Chemistry Pumping Units VARIO® select

The combination of speed controlled VARIO® chemistry diaphragm pumps and the new VACUU·SELECT vacuum controller makes the VARIO® select chemistry pumps the ideal solution for chemical processes that require precise vacuum, such as rotary evaporation, vacuum drying or vacuum concentration.

  • High chemical resistance and therefore ideally suited for pumping aggressive gases and vapours.
  • Short process times and smooth running due to optimal setting of the pressure via the VACUU·SELECT controller.
  • The VARIO® technology controls the vacuum precisely and efficiently via motor speed.
  • Power consumption, maintenance and noise are exceptionally low.
  • The outlet catchpot and solvent condenser combine to prevent solvent vapor emissions into the lab, allowing for nearly full recovery of solvents.


Country-specific power cord versions available on request.
