Consist of an evaporating Flask rotated by a non-sparking induction Motor in a heating water Bath. Vacuum Distillation of solvent at high and low Temperature is achieved quickly and efficiently by use of speed controller provided. It prevents foaming an vacuum and bumping of the liquid. Other application include vacuum drying of powders and slides. Low Temper ature Vacuum distillation of heat sensitive compounds. The introduction tube permits continuous feed of the liquids into evaporating flask and also distillation under Controlled atmosphere.
