Learn about the general characteristics of a rotary evaporator:


1. What are the advantages of the rotary evaporator?

The rotary evaporator has the advantages of compact structure, compact and efficient operation, intuitive operation and no metal ion pollution. Suitable for laboratory, production pilot and extraction of valuable materials. Its sealing performance is comparable to that of foreign machines.

2. What type of vacuum pump is used for the rotary evaporator?

A water circulation pump is recommended, which has the advantage of being resistant to various solvent corrosion and can be evacuated to -0.095 MPa (to meet the requirements of use). The vacuum pump can be selected according to the size of the evaporator, and can be supplied with various types of vacuum pumps.

3. What are the factors that affect the efficiency of the rotary evaporator?

For the same specification machine, there are mainly: steam temperature, vacuum degree and cooling water temperature are restricted by the heat resistance of some materials. It is impossible to increase the steam temperature infinitely during work, so high vacuum and low cooling water temperature are the two to improve efficiency. The main factor (optional cryopump, lower water temperature).

4. What is the difference between a vertical condenser and a diagonal condenser?

There is no obvious difference in essence. Vertical condensers are gaining popularity due to their small footprint. Large-capacity evaporators generally use a vertical condenser.
