Product Description

BrandTech VACUUBRAND MD1C+AK+EK Oil-Free Diaphragm Vacuum Pump is a dual voltage pump 100-115V/200-230V 50-60Hz, 120V 60Hz. Supplied with a US power cord.

MD 1C chemistry diaphragm pump with separator at the inlet and exhaust vapor condenser

This chemistry vacuum system has a wide range of applications like evacuation, evaporation and pumping of gases and vapors. This system is usable for increased vacuum requirements with high boiling solvents and often replaces rotary vane pumps. Typical applications are rotary evaporators and vacuum drying ovens. The separator at the inlet (AK), made of glass with a protective coating, retains particles and liquid droplets. The waste vapor condenser at the outlet (EK) is highly efficient and compact. The condenser enables near-100-percent solvent recovery, efficient recycling and active protection of the environment.

Performance Features:

  • Outstanding chemical resistance and superior vapor tolerance
  • Exceptionally high performance even at low vacuum
  • Excellent ultimate vacuum even with gas ballast
  • Whisper quiet and low vibration
  • Excellent environmental friendliness due to efficient solvent recovery
