Abstract
Spinning band fractionating column apparatus is disclosed having a spinning band formed with a magnet embedded in its bottom end in the manner of a magnetic stirring vane for rotation by a rotating external magnetic field at the bottom of the apparatus. Reflux is controlled by an angled drip edge on a rotatable condenser column that passes a portion of dripped condensate to a collecting spout with the portion varying as rotation of the condenser column brings the drip from said edge closer or further from center opposition with the spout.
