The VACUUBRAND MD 1C VARIO® chemistry pumping unit is an advanced, oil-free vacuum system designed for automatic vacuum control in demanding laboratory applications, particularly rotary evaporation and high boiling solvents.
Using VARIO® technology, the pump continuously adjusts motor speed to precisely match vacuum demand, ensuring optimal process conditions while reducing energy consumption and wear. The integrated CVC 3000 vacuum controller enables fully automated operation, including automatic vapour pressure detection and vacuum adjustment.
This system delivers stable, hysteresis-free vacuum control, preventing superheating and foaming, and ensuring maximum protection of sensitive samples.
