Mar 02, 2016 We often get asked: What temperature should I set my rotary evaporator to? A good general guideline to follow is the Rule of 20. This rule states that your bath temperature should be 20C hotter than the boiling point or vapor temperature you are trying to achieve, and the coolant temperature should be at least 20C cooler than the vapor temperature.

Mar 02, 2020 Rotary evaporation means that the evaporation is completed by rotary process. Under the low temperature and negative pressure, the evaporation flask is rotated by a motor in a thermostat water bath, which makes liquid form a thin film across the interior of the flask so as to increase the evaporation area.

Rotary evaporation: Solvent is removed at reduced pressure by mechanically rotating a flask in a controlled temperature water bath. Condensed solvent is collected in a separate flask: Volatile compounds are typically lost. Recovery of less volatile material may be lower than expected due to entrainment of the analyte the solvent vapor.
