摘要: In a centrifugal evaporator for evaporating mixture of liquids having different volatilities and specific gravities, the being contained in test tube (14) pivotally mounted on rotatable support arm (12) sealable vacuum chamber (16), is rotated up to speed order 2000 rpm before evaporation more volatile component occurs, only then progressively evacuated. The motor preferably three-phase induction connected electric supply frequency convertor.
