Heidolph Hei-VAC Vario Control RPM-regulated vacuum pump
Chemically resistant membrane pump for Hei-VAP Expert Control and Hei-VAP Ultimate Control devices. The vacuum can be controlled by changing the speed of the pump, enabling constant distillation conditions and shorter operation times.
• Even if the gas ballast valve is open an excellent ultimate vacuum is reached when working with easily condensable vapors. This makes distilling high boiling point solvents such as DMF or DMSO possible at low bath temperatures.
• Condenser is not in scope of delivery
