How to use a Rotary Evaporator

How to use a Rotary Evaporator

Apr 01, 2010 The flask with the solution is placed on the rotary evaporator. The use of a bump trap prevents the solution from accidentally splashing into the condenser (and being contaminated). It is highly advisable to start with a clean bump bulb in case something bumps over after all! This would allow the experimenter to recover the solution or solid. 3.

Applying Rotary Evaporator To Cannabis distillation

Applying Rotary Evaporator To Cannabis distillation

As the pressure is reduced using a vacuum pump in the rotary evaporator, the boiling point of the solvent, ethanol in this case, is lowered. Typically, the distilling flask (A) is filled to 50% volume. The water bath (B) is heated to 30-40C. The condenser temperature (F), controlled by a recirculating chiller, is set to -10C to 0C.
