Buchi 20/40/60 rule for Rotary Evaporators

Buchi 20/40/60 rule for Rotary Evaporators Optimal Distillation parameters for a rotary evaporator vary according to solvent in use: 1. Set water bath temperature to 60oC – It does not need to be higher! 2. The cooling water temperature should be below 20oC. 3. Adjust the needed vacuum for a solvent boiling point of 40oC according to list below.
