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 are the steps to use the rotary evaporator?

After adjusting the position of the rotary evaporator and the bath, turn on the vacuum. The material can be sucked into the rotating bottle with a hose on the feeding port. Turn on the low-temperature coolant circulation pump. The water bath must be energized after adding the medium. Turn on the control switch and adjust the knob to the optimal speed to recover the solvent. Turn off the vacuum pump, turn on the switch to deflate, and take out the dissolved coal in the collection bottle.

4. What are the precautions when using the rotary evaporator?

When the set temperature of the low-temperature cooling circulation pump is lower than 0 degrees, the cooling medium cannot use water. Contact our technicians to replace the appropriate medium (such as glycol), and inject 1/2 volume of the medium into the heating pot to ensure that it is submerged 1/2 of the evaporating flask is enough.

5. How to choose a cryopump for rotary evaporator?

We recommend choosing a low-temperature coolant circulating pump, which has the advantages of energy saving, water saving, anti-fouling and anti-scaling. According to your needs, we can provide various types of circulating water vacuum pumps.

6. What is the power supply of the rotary evaporator?

The power supply of our rotary evaporator is generally 220V50HZ and 110V60HZ
