analytical chemistry - Does a rotary evaporator need a draft chamber and a vacuum pump ...

May 14, 2013 While I agree that a vacuum pump can be of use, I do not require my solvent to boil, therefore I do not need vacuum. As for the draft chamber, I completely fail to see its implication. I believe that since the rotary evaporator is a completely closed system, there is no way DCM vapor could leak, rendering the draft chamber useless.
