Rotary evaporator is the use of stepless speed control glass rotating bottle constant speed rotation, the material in the bottle wall to form a large area uniform film, and then by the intelligent constant temperature water bath on the rotating bottle of uniform heating, vacuum conditions, high-speed evaporation, Efficient glass condenser cooling, recovery in the collection bottle.



1. Using PTFE + fluorine rubber seal cover, to maintain a high vacuum degree. Gas-liquid separation, no reflow .

2. USES the main and secondary efficient double condenser to ensure high recovery rate.

3. Rotating bottle with nut connection, it is easy to load and unload.

4. There is tap valve under the collection bottle mouth, recycled solvent is very fast.

5. Feeding continuously.

6. Vacuum gauge is to make sure the best work vacuum degree can be adjusted for the low boiling point materials.

7. Water bath with digital and continuous temperature controlling.

8. Reasonable structure, special materials . The mechanical structure mainly use stainless steel and aluminum alloy parts, glass pieces are all made of high temperature resistant and high boron glass. Imported Electrical key-module. Rubber seal is easy to adopt the new international, making it easy for users to purchase and update.
