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. A water bath below the rotating flask provides that heat.
