Abstract: A rotary evaporator is described utilizing a magnetically driven fluorocarbon cylinder, operating within a solvent container, to create a thin solvent film for rapid evaporation without the usual requirement for rotating the entire solvent container assembly. Infra-red heating is employed for efficient evaporation rates. Solvent heating is controlled during evaporation by a single temperature probe, turning the infra-red heater on and off on demand of the probe. Over heating of the product is prevented by maintaining a solvent residue at or near the conclusion of an evaporation.
