Jul 19, 2018 Water takes a lot of energy to heat, and heating a bath from room temperature (usually 20 - 25C) to, for example, 80C, will take a lot more time than heating it from room temperature to 30C (a common target vapor temperature for rotary evaporation). Oil baths may take even longer to heat, as they can go as high as 180C.

The benefit to using a rotovap over a simple distillation system is that the rotation of the evaporating flask, combined with a heated water bath, increases the surface area of the product. This makes the distillation go faster and keeps the mixture evenly mixed and heated, to promote a stable and even evaporation.
