Rotary evaporator vs short path distillation

Rotary evaporator and short path distillation are both the equipment to extract or concentrate substances, which are widely used in many fields and high-efficiency. Rotary evaporator and short path distillation have the same function, but rotary evaporator can only process one single material while short path distillation can process two or three materials. Besides that, there are still some comparisons and they are as follows:

  1. In the short path distillation equipment, there is a short path transferring extracted materials from the evaporation flask to the condensing part, which may cause the extracted materials left at the short path easily. In this way, on the one hand, users need to clean the short path very often to guarantee the quality of experiment, which costs much time and money. On the other hand, the left extracted materials caused the waste of resource. In the rotary evaporator equipment, the extracted materials are transferred into condensing part directly with no distance, which prevents the waste of resource.

  2. Because the cleaning requirements of laboratory glassware, users should clean them very frequently, in order to guarantee the quality of experiments. Therefore, the glassware in rotary evaporator equipment and short path distillation equipment should all be cleaned frequently.
  3. Rotary evaporator and short path distillation are both used for the extraction of heat-sensitive substances. And they both are widely used in many fields, including people’s daily life at home, chemical, biochemical, make up and perfume, industrial and other fields.
