Rotovap features a specially designed motor and worm gear, which provides constant rotation at speeds from 10 to 180 rpm.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, which is caused by the gentle heating from the water bath.
