ABSTRACT:
A rotary evaporator for laboratory scale solvent evaporative procedures is described. A magnetically driven fluorocarbon coated rotor, operating within a container for solvents, creates a thin film for rapid solvent evaporation without the usual requirement for rotating the entire solvent container assembly. Rotary seals are eliminated, increased control over bubbling and foaming at higher vacuum is obtained, and continuous solvent addition is simplified.
