How to adjust the rotational speed of the rotary evaporator? How much is appropriate? This is a problem that many rotary evaporator customers are confused about.The rotary evaporator is mainly used for vacuum distillation. It is best to have a large boiling point difference between the two materials, and the boiling point is not easy to separate;At present, it is mainly used for separation, solvent recovery, crystallization, and drying in the pharmaceutical, chemical, and biopharmaceutical industries, and its application is becoming more and more extensive.
How much the rotary evaporator speed is adjusted, which is related to the solvent to be evaporated in the rotating bottle, the heating temperature and the degree of vacuum.Why is it closely related to these? The higher the boiling point of the solvent, the less the steam is evaporating. When the heating is started, the rotation speed can be adjusted slowly. As the temperature increases, the rotation speed can be appropriately adjusted.

If the temperature is high, the solvent that is easy to be bumped can be adjusted slowly when the speed is adjusted.

There is a principle for the speed regulation of the speed. No matter what kind of solvent, it should not be too fast at the beginning. It can be adjusted slowly with the demand of the experiment. The low boiling point can be adjusted slightly faster, and the boiling point can be adjusted to a high point. This can be determined on a case-by-case basis.

ZZKD is specialized in rotary vacuum evaporator,The most popular ones are 2L rotary evaporator, 5L rotary evaporator, 20L rotary evaporator, 50L rotary evaporator.
