What Is Rotovap -

Distillation is a physical method of assorting mixtures depending upon the difference in the boiling point of the component substances. In simple words, the working principle of distillation is to heat a mixture at a specific temperature, collect the hot vapors, and condense to separate the component substance.

May 08, 2020 In general, your bath temperature should be 20C higher than the boiling point of the substance you want to evaporate. And your coolant should be 20C or more lower than the vapor temperature. For example, if the boiling point of your substance is 40C, a bath temperature of 60C and coolant temperature of 20C should provide an optimal setup.
