RPM Regulated Vacuum Pumps

Category Heidolph Rotary Evaporator Accessories
Manufacturer Heidolph

RPM regulated pumps adjust their speed individually and come to a complete stop when the required vacuum level is reached

Your Advantages:

  • Speed adjustment stops completely if vacuum is reached and runs intermittently at very low speed to hold vacuum constant
  • Increased diaphragm performance life due to periods of non-operation
  • Low energy consumption due to intermittent operation
  • Significant noise and vibration reduction due to periods of non-operation
  • Operates without vacuum valve
  • Most precise vacuum level at all times

Rotavac Vario Pumping Unit - Fully controllable stand-alone pumping unit including vacuum controller

  • Three-stage diaphragm pump is made from chemical-resistant material
  • High suction capacity of 1.7 m³/h for fastest evacuation
  • Achieves an ultimate vacuum of 5 mbar
  • Precise vacuum control avoids bumping and eliminates foaming of your evaporation solution
  • Due to automatic vacuum supply to the process parameters you have more time for important laboratory activities
  • Can be combined with a condenser
  • Power input: 160 W
  • Weight: 6.0 kg
  • Dimensions (without condenser): L263/W193/H299 mm

Rotavac Vario Control

  • Three-stage diaphragm pump is made from chemical-resistant material
  • High suction capacity of 1.7 m³/h for fastest evacuation
  • Achieves an ultimate vacuum of 2 mbar
  • 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
  • Can be combined with a condenser
  • Power input: 160 W
  • Weight: 5.4 kg
  • Dimensions (without condenser): L167/W236/H196 mm

Rotavac Vario Tec

  • Two-stage diaphragm pump is made from chemical-resistant material
  • Suction capacity of 1.0 m³/h
  • Achieves an ultimate vacuum of 12 mbar
  • Recommended for solvents with low or medium boiling points
  • Can be combined with a condenser
  • Power input: 160 W
  • Weight: 4.3 kg
  • Dimensions (without condenser): L156/W236/H196 mm
