• 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
