how rotary evaporator works?

How Rotary Evaporator Works - The process of using a rotary evaporator to remove volatile solvents from a sample is called rotary evaporation. The sample is placed in a round-bottomed flask and heated. As the sample heats up, the solvents begin to evaporate. The evaporating vapors are then drawn through a condenser, where they are cooled and collected.
