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.

Apr 07, 2022 A rotary evaporator is essentially a reduced pressure distillation: a solution in a round bottomed flask is placed in the water bath of the apparatus (Figure 5.66a), and rotated while the system is partially evacuated (by a water aspirator or vacuum pump). The reduced pressure in the apparatus causes the solvent to boil at a lower temperature ...

What is the purpose of the water bath in a rotary evaporator?

View Larger Image. A rotary evaporator is often used with a water bath. A rotary evaporator works by reducing the pressure over a solution using a vacuum pump, thereby reducing the boiling point of the liquid. As the liquid evaporates quickly, it pulls heat from the solution. That heat needs to be replaced so the evaporation does not stop.
