1. What is the working principle of the rotary evaporator?

It is heated under constant temperature and rotated under negative pressure to form a film, and at the same time, the solvent is evaporated and condensed for recovery.It is especially suitable for concentration, crystallization, separation and recovery of heat-sensitive materials.

2. What are the uses of the rotary evaporator?

It is generally used for separation, crystallization, drying, purification and other operations in biopharmaceutical, pharmaceutical, chemical and chemical industries.

3. What is the difference between the explosion-proof rotary evaporator and the ordinary type?

The explosion-proof rotary evaporator adopts an AC generator, stepless speed regulation (frequency conversion speed regulation), brushless, and no spark. The manual control switch adopts two-way control, the current is less than 3mA, and the explosion-proof function is good.

4. What are the characteristics of the rotary evaporator compared with other evaporators?

All rotary evaporators have a built-in lifting motor, which can automatically lift the flask to the top of the heating pot when the power is off. The material rotates under vacuum conditions to form a layer of liquid film in the evaporating flask, which has a larger heating area. The rotation effectively suppresses the boiling of the material. In view of its characteristics and convenience, the rotary evaporator can be used for rapid distillation and extraction, even for operators without operating experience.

5. How to choose the supporting equipment of the rotary evaporator?

We recommend choosing a low-temperature coolant circulating pump, a circulating water vacuum pump, you can also contact us, and we will make suggestions according to your needs.
