12 Support the flask with your hand while you vent the rotary evaporator by turning the stopcock at the top of the rotary evaporator. If your flask contains a fine solid, you should vent slowly to prevent the solid from being sprayed around the flask (or indeed the whole rotary evaporator). 13 Turn off the rotation and remove the flask.

Why Rotary Evaporation Is More Efficient Than Standard Distillation

Jul 19, 2018 An increase in temperature will increase the vapor pressure, leading to evaporation. However, whether you’re using increased temperature in a rotary evaporation or standard distillation setup, it takes time and energy to heat a bath. This reduces the efficiency of using increased temperature to evaporate the solvent.
