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.
