A rotary evaporator (rotovap) is a fast and effective method of removing solvent from a flask. A rotovap removes solvent by reducing the pressure within the flask using a vacuum, rotating the sample to increase its effective surface area, and heating the solution. Pre-weight a round bottom flask; fill it less than halfway with the solution

• 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
