EVAPORATORS - ROTARY

  • Rotavapors Buchi

    Since its introduction in the fifties, the Buchi Rotavapor has become an essential instrument in the modern laboratory and pilot plant. As acknowledged world leaders in the field of rotary evaporators, Buchi products have set enviable standards of performance and reliability. The new models listed in the following pages continue the Buchi traditions and show unsurpassed levels of innovative design, ergonomics and functional efficiency.

    Operating principle

    The Rotavapor is essentially a distillation unit incorporating a rotating evaporation flask. The Rotavapor will evaporate solvent at a much faster rate than systems using stationary evaporation flasks.

    The rotation transfers a thin film of the liquid sample to the whole of the inner surface of the flask, markedly increasing evaporation rate and assisting heat transfer from the heating bath. The rotating flask and vapour duct have a sealing system which allows operation under vacuum, further accelerating the evaporation process because of the reduction in boiling point of the solvent and efficient removal of the vapour phase. Vacuum operation also permits heat-labile materials to be successfully concentrated without degradation.

    The evaporators can be evacuated down to 1 mbar if the vacuum seals are maintained in good condition. A high level of operational safety is ensured when working under reduced pressure by the provision of 'Plastic + Glas' safety-coated glassware and a new polycarbonate safety screen which is available as an option for all bench-scale models.

    A continuous feed facility considerably increases the capacity of the units and distillate withdrawal facilities on some units allows uninterrupted operation.

  • Model Range

    There is a range of models covering an evaporation flask capacity from 30ml to 100 litres. The majority of these models may be used on the laboratory bench; the two largest models, one of which is Ex-Proof. are free-standing units desiqned for use in pilot plants etc.

    A comprehensive range of accessories is available.

    The range consists of:
