An easy concept to remember for solvent removal by a rotary evaporation is the 20/40/60 Rule. 20/40/60 Rule. The vacuum is adjusted properly for each solvent with an operating bath temperature of 40℃ which is subsequently condensed at 20ºC. The rule can be applied to lower bath temperatures too, e.g.: Cooling water: 0ºC; Vapor: 20ºC; Bath: 40ºC.
