A Rotary evaporator is a distillation unit that incorporates an efficient condenser with a rotating sample flask. As the flask containing the solvent is rotated, it continually transfers a thin layer of liquid over the entire inner surface. This gives a very large surface area for evaporation, the sample or Florentine flask can additionally be heated by an accessory bath to accelerate the process. The entire system has been designed to be vacuum tight, an accessory vacuum pump can be connected to reduce the overall pressure and hence the boiling point of your sample.

Each unit is also provided with an easy to use vacuum release and a continuous feed system, which allows more solvent to be drawn into the rotating Florentine flask without the need to stop the operation.

There is also a plastic coated version available, providing additional safety when using the glassware under vacuum. The plastic coating ensures, that operator injury is less likely, should any glass component fail while under vacuum. The added security of a plastic coated also gives the operator sufficient time to transfer any potentially dangerous chemicals to a suitable vessel without spillage.

The RE402 rotary evaporator comes with a vertically orientated, cold finger glass condenser for use with ice or dry ice for volatile or low boiling solvents. Providing a cooling solution without the necessity for a constant supply of cooling water.
