Diaphragm Vacuum Pumps LABOPORT® SD
KNF Neuberger

  • Integrated KNF self-drying system ensures that condensate is quickly removed from the pump heads without the vacuum being altered. This significantly reduces process time and preserves the pump heads.
  • Chemically resistant and thus ideal for use with extremely aggressive / corrosive gases and vapours.
  • Pump head: PTFE.
  • Diaphragm: PTFE-coated.
  • Valves: FFPM.

Rotary evaporation, distillation, vacuum oven, centrifugal concentration.

Specifically designed for the use with ovens or wet gases. Devices are equipped with a solenoid valve to purge out possible solvent remains from the pump head. This ensures a stable vacuum and an optimised life time for the diaphragms.
