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.

Jul 21, 2017 If you use an oil vacuum pump with a rotovap, the pump oil will turn black and start to smell like ethanol. That’s because the vapors are getting trapped in the oil case and contaminating the inside of the pump. This dramatically decreases the lifespan of the pump and forces you to change oil too frequently.
