Explanation of the principle and usage of the rotary evaporator product

The main content of this video is to introduce the product features and functions of the Xiande rotary evaporator, as well as the working principle of the rotary evaporator and the functions of the accessories configured in the experiment.

Firstly, the rotary evaporator is mainly used for concentration and extraction experiments conducted in the laboratoryBy electronic control, the flask is rotated at a constant speed at a suitable speed to increase the evaporation area. Use a vacuum pump to keep the evaporation flask under negative pressure. The evaporation flask is heated at a constant temperature in a water bath while rotating, and the solution inside the flask is heated, diffused, and evaporated under negative pressure in the rotating flask. Heat the solvent in the distillation flask with a heating bath at a temperature close to the boiling point of the solvent; At the same time, it can also rotate to form a thin film of solvent, increasing the evaporation area. In addition, under the action of an efficient cooler, hot steam can be rapidly liquefied, accelerating the evaporation rate.
