The rotary evaporator
is a common laboratory equipment, consisting of a rotary motor, distillation flask, recovery flask, heating pot, condenser tube and other parts. It is mainly used for continuous distillation of volatile solvents under reduced pressure conditions, and is widely used for large-scale concentration, drying, extraction and recovery of samples. It is the ideal equipment for scientific research experiments and industrial mass production in chemical, pharmaceutical, food, environmental protection and university fields. -

The rotary evaporator
continuously distills a large number of volatile solvents under reduced pressure conditions, and the concentration of the extraction solution and the distillation of the receiving solution can separate and purify the reaction products. The large-capacity rotary evaporation flask is used to increase the evaporation area, which is placed in a reduced-pressure water bath and heated while rotating to make the solution evaporate by diffusion efficiently. -

How to use the rotary evaporator
1. Turn on the low-temperature coolant circulation pump.
2. Open the water pump circulating water.
3. Turn on the vacuum pump, to have a certain vacuum and then start to rotate.
4. Adjust the height of the distillation flask and rotation speed, and set the appropriate water bath temperature.
5. Steam first stops the rotation, then pass the atmosphere, and then stops the pump, and then finally removes the distillation flask.

When using the rotary evaporator
, each joint needs to be coated with a layer of vacuum grease before installation to ensure the vacuum level of the reaction process. If the vacuum level is too low, pay attention to checking the gas tightness of each joint, vacuum tube, and glass bottle. If the sample viscosity is very large, the rotation speed should be slowed down, slow rotation, the formation of the liquid surface is conducive to solvent evaporation.As a supplier of rotary evaporators
