Vacuubrand MZ 2C Diaphragm Vacuum Pump (Refurbished)

The Vacuubrand MZ 2C is a two-stage chemistry diaphragm pump engineered for laboratories requiring dependable, oil-free vacuum for processes involving corrosive gases and solvents. Designed with a chemically resistant flow path—constructed entirely from fluoroplastics—and durable PTFE sandwich diaphragms, the pump delivers long operating life and high resistance to aggressive vapors.

Thanks to its two-stage configuration, the MZ 2C achieves both strong pumping speed (2 m³/h) and a deep ultimate vacuum of 7 mbar, making it a versatile choice for routine and intensive tasks such as rotary evaporation, vacuum drying, solvent concentration, and vacuum ovens. The integrated gas ballast valve enhances vapor handling, maintaining stable performance even under high solvent loads.

Quiet operation, minimal vibration, and a maintenance-free drive system ensure smooth daily operation in busy research or production environments.
