Rotary evaporators are essential laboratory equipment for process of evaporation, concentration, drying, separation, and solvent recovery.  They are are mainly used for continuous distillation of large amounts of volatile solvents by reducing the pressure to lower the solvent boiling point, rotating the sample to increase the effective surface area and heating the solution in the bath. Then the evaporated solvent condenses in a cooled glass condenser.

This rotary evaporator RE200-Pro comes with a 20L volume evaporating flask and 10L volume receiving flask and vertical condenser as standard.  Other glassware assembly configurations (large flasks, diagonal and dry ice condensers or different sizes of evaporating flasks etc.) are available upon request.  See details in the accessories document attached.
