Rotary evaporator / parallel evaporator

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
