  • How does the rotary evaporator work? - Lab

    2020-3-6 · A rotary evaporator is an expensive laboratory apparatus that is used for gentle and efficient removal of solvents from various samples by means of evaporation. This process necessitates the removal of extra solvents from less volatile samples. Rotary evaporators are very important and are found in every organic laboratory because of their efficiency in performing this task.

  • How Does a Rotary Evaporator Work - USA Lab

    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.
