Vacuum requirements for rotary evaporators can vary greatly depending upon the solvent and evaporating temperature. This is 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 to minimize the impact on environmental and laboratory air
