Vacuum requirements for rotary evaporators can vary greatly depending upon the solvent and evaporating temperature. This is the reason why a modern vacuum system includes built-in vacuum regulation to help you reach optimum evaporating rates. This significantly shortens the process duration and minimizes environmental and laboratory air pollution.

Process requirements
* medium to high vacuum requirements
* fast and highly sensitive vacuum control with samples that tend to super heat or foam
* vacuum control for short process times and high reproducibility
* optimum condensation in the cooler of the rotary evaporator
* recovery of residual solvent vapors after the pump

Pump requirements
* excellent chemical and condensate compatibility
* effective gas ballast system to prevent condensation in the pump
* very good ultimate vacuum even with gas ballast operation for continuous evaporation
* low ultimate vacuum required for low evaporation temperatures or high boiling solvents
* emission condenser for solvent recovery and to minimize environmental and laboratory air pollution
* for applications with large amounts of inflammable solvents: pumps and gauges with ATEX approval
