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.

Automatic features are available to sense the vapor pressure of the solvent and use that as a set point. Then there are foam sensors, which detect the foam inside the evaporating flask and aerate the system slightly to make sure that the foam collapses. The foam sensor allows automatic, unattended distillation of foaming samples.

Jun 26, 2017 This is normally caused by heating too quick or applying too strong of a vacuum. The chances of it causing damage and splashes into the rotovap are increased if your evaporation flask is more than half full. Go slow, start with little vacuum and visually inspect your sample while decreasing the pressure so that bumping doesn’t occur.

Sep 10, 2021 By automatically breaking the vacuum, foam formation is prevented. If you ignore the foam, the foam will eventually spread sample all over the glassware of the rotary evaporator and enter the condenser. At this point, you will have to clean the entire system, a task that is certainly tedious and better left avoided.
