When vacuum degree is not appropriate, the reagent will boil up and can not be fully recovered. When an automatic vacuum controller is connected with rotary evaporators, ideal vacuum level can be obtained inside the rotary evaporator. Especially for the concentration of volatile reagent, the optimal recovery rate can be obtained. During vacuum distillation, operator controls rotary knob to regulate vacuum degree, and then reagent is extracted step by step, which makes the experiment more convenient and simple. It can also be used with vacuum drying ovens and reactors.
