A rotary evaporator is a device used in chemical laboratories for the efficient, gentle removal of solvents from samples by evaporation. Rotary evaporator is most often used to separate solvents with low boiling points, such as n-hexane or ethyl acetate, from compounds which are solid at room temperature and pressure. However, careful application also allows removal of a solvent from a sample containing a liquid compound, if there is minimal co-evaporation (azeotropic behavior), and a sufficient different in boiling points at the chosen temperature and reduced pressure.
