Why Rotary Evaporation Is More Efficient Than Standard Distillation

Why Rotary Evaporation Is More Efficient Than Standard Distillation

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.
