Rotary evaporation: Solvent is removed at reduced pressure by mechanically rotating a flask in a controlled temperature water bath. Condensed solvent is collected in a separate flask: Volatile compounds are typically lost. Recovery of less volatile material may be lower than expected due to entrainment of the analyte the solvent vapor.

A rotary evaporator works by the general assumption that at each given time, the boiling point of the solvent in question is much lower than the boiling point of the liquid surrounding it. As the boiling point of liquids slowly reduces when you decrease their pressure, it allows the solvent to be vaporized at lower temperatures than their standard boiling point at normal pressure.
