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