The working principle of the laboratory rotary evaporator is based on the principles of evaporation and condensation in physics. Under the combined action of heating and rotation, the solvent inside the evaporation bottle gradually heats up and evaporates into steam. The steam is cooled and re condensed into liquid in the condenser, and then flows into the collection bottle. At the same time, the vacuum system continuously extracts air from the system, reducing the pressure inside the system, allowing the solvent to reach its boiling point and evaporate rapidly at lower temperatures.

Rotary evaporator, also known as rotary evaporator, is a widely used evaporation instrument in laboratories, consisting of a motor, distillation flask, heating pot, condenser tube, and other parts. Rotary evaporator is an efficient, energy-saving, and easy to operate laboratory evaporation equipment that plays an important role in multiple fields.
