experimental chemistry - Chemistry Stack Exchange

Apr 07, 2015 A rotovap typically uses a cold condenser to condense the solvent into a collection flask. But the distillation is typically done under weak vacuum as well. So the solvent sitting in the collection flask seem susceptible to re-vaporizing and getting sucked into the vacuum pump.

Home Environmental Health Safety UCI

Connect the bump trap to the rotovap and secure with the metal clip or a keck clip depending on the model of rotovap (pictured below). The bump trap should be kept clean, it provides a receptacle in case the solution splashes or boils beyond the flask. A clean bump trap can allow for recovery of any solution that “bumps”.
