How Does a Rotovap Work?

Zhengzhou Elab Instrument Co., Ltd. focus on manufacturing products like Reactors, Rotovap, Temperature Control Equipment and Vacuum Pumps.We produces many kind Rotovap,such as Rotovap, Rotary evaporator,Lab Rotary Evaporators,Rotovap distillation. Every component used for our products is of premium material and has been tested to guarantee longer service life.

1. Decompression: The rotary evaporator operates under vacuum, thereby reducing the boiling point of the solvent. This allows the solvent to evaporate at temperatures lower than atmospheric pressure, which is very useful for heat-sensitive compounds.

2. Heating: Place the sample in a round-bottomed flask and partially immerse it in a temperature-controlled water bath. The heat helps to evaporate the solvent.

3. Rotation: The flask rotates during evaporation. This increases the effective surface area of the liquid, exposing more solvent at one time to reduced pressure, resulting in significantly higher evaporation rates.

4. Condensation: The evaporated solvent goes into a condenser, usually a glass coil or container, where it cools and is converted back into a liquid.

5. Collection: Collect the condensed solvent in a separate flask for reuse or proper disposal.

6. Prevent boiling: The rotation of the flask helps to prevent "boiling", that is, when a large amount of solvent vapor rapidly forms and replaces the surrounding liquid. This can be a problem during stationary evaporation, but rotation helps disperse the solvent into a film, thereby reducing this risk.

7. Control vacuum: The degree of vacuum can be controlled, which is important for samples that are sensitive to pressure changes. Some rotary evaporators sold have additional traps to prevent solvents from entering the vacuum pump, which is especially important when using a membrane pump as a vacuum source.

8. Temperature control: the water bath temperature should not exceed the boiling point of the solvent. For small amounts of common solvents, bath heaters may not be needed, and heat from the room is sufficient.

9. Safety and maintenance: It is important to use distilled water in the heating bath to minimize scale buildup and to clean the condenser regularly to maintain efficiency.

The laboratory rotary evaporator is a versatile tool that can be used for a variety of applications, including solvent removal and concentration, drug discovery, essential oil extraction, and polymer research.
