Vacuum Pumps Rotavac Vario Control / Heidolph Scientific

Suitable for Rotary evaporators Hei-VAP series. Controllable vacuum pumps for digital regulation of the vacuum via operation panel or directly at the unit.

• High distillation rates and reduced process time by 30 %.
• Solvent recovery up to 99 %.
• Pump stops automatically as soon as the set vacuum is reached and reliably holds the vacuum constant
• Increased diaphragm performance life due to periods of non-operation
• Low energy consumption
• Significant noise and vibration reduction
• The pumps can be combined with a condenser

-3-stage diaphragm pump
-High suction capacity for fastest evacuation
-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
