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