Rotary evaporators are mostly used in laboratories for the effective removal of solvents from the samples by the process of evaporation under a vacuum. In simple terms, rotary evaporators are used for the methods of purification and liquid separation. Some of the main functions of the rotary evaporator is crystallisation or recrystallization, chemical synthesis, solvent distillation and recycling and concentration of solutions and suspensions.

Consisting of a heating bath with a rotating flask, vacuum pump, evaporation flask, snakelike condenser pipe, motor and the receiving flask, the rotary evaporator is also called rotovap or rotavap. The heating bath with the rotating flask is the portion where the liquid is distributed so that it can evaporate easily. Now, the rate of evaporation is regulated by the size of the flask, the temperature of the heating bath, the distillation pressure, the temperature of the coolant and the speed at which the evaporation flask rotates.

Applications of the rotary evaporator

From chemical laboratories, food and beverage industries to the production of medical products, the application of rotary evaporators are widespread. Below are few uses of the rotovap:

  • The rotary evaporators are commonly used in the chemical laboratories. From evaporation, separation, crystallization, to drying and solvent recovery processes, rotovaps are essential for all industries that deal with solvents.
  • Over the years, the use of rotovap has increased in the culinary industry for molecular cooking. Molecular gastronomy refers to the section of science which uses chemical principles in cooking. In molecular gastronomy, rotary evaporators are used to prepare extracts and distillates. Rotary evaporators help to retain the aroma of the cuisine, which otherwise get lost in the process of heating. An ideal amalgamation between experimental and modern-day cooking, rotary evaporators have gained prominence in the cooking industry.
  • In educational institutions, rotary evaporators are widely used to conduct experiments in laboratories.
