May 17, 2017 The volume of solvent to be evaporated on the rotovap is often underestimated and too small of a round bottom evaporation flask is used for it. Instead of changing to a larger evaporation flask it is often more tempting to fill the flask as full as possible. This is not a good idea because the fuller your flask the more likely you are to ...

Pour the mixture of solvent and desired compound in a round bottom flask. Best results are achieved when the flask is filled less than half full of the solution. Fill the rotovap cold traps with dry ice. Attach a glass “bump trap” which prevents any solution from entering the main part of the rotovap. Secure with a Keck clip.

• A rotary evaporator (“rotovap”) is used to remove solvent from a sample in a round bottom flask or vial by boiling off the solvent under reduced pressure. Heating the rotovap’s water bath above room temperature can hasten the removal of higher-boiling solvents, if necessary. This SOP is written for a standard Heidolph rotary evaporator
