Laboratory  equipment Rotary evaporator is mainly used for continuous distillation of a large number of volatile solvents under reduced pressure conditions. In particular, the reaction product can be separated and purified by the concentration of the extract and the distillation of the liquid at the time of chromatographic separation. The basic principle of the rotary evaporator is vacuum distillation, that is, in the case of reduced pressure, when the solvent is distilled, the distillation flask is continuously rotated.
