Rotary evaporators: A rotary evaporator is used to remove a solvent fr om a flask without having to heat that flask to the boiling point of the solvent at one atmosphere. This has the advantage that it is quicker and is less likely to cause thermal decomposition to the sample. All the rotary evaporators are connected to a source of vacuum.
