How to choose a rotary evaporator when doing distillation .

The rotary evaporator is an experimental equipment for rectification and purification in the laboratory. It is heated by constant temperature and rotated under reduced pressure (negative pressure) to form a film to continuously evaporate a large amount of volatile solvent, evaporate efficiently, and then condense and recover the solvent. The effect of purifying the separation, that is, under .
