Mar 02, 2016 · For instance: if you were trying to boil off a substance that has a boiling point of 70°C, you would want to set the bath temperature to 90°C and have the coolant in the condenser be 50°C or less. If you'll be applying a vacuum, don't forget to check how the reduced pressure will effect your solvent's boiling point!

Rotary evaporator, or rotovap, is an instrument used to distill a solvent. (Everyone calls it a “rotovap” even though rotovap is a brand name). The purpose of distillation is to separate a given mixture into its components based on their respective volatilities, through the process of evaporation and condensation (liquid-gas-liquid).
