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 reaction is the rotary evaporator generally used for?

Solid-liquid separation, strong acid or weak base reaction. Can not carry out strong alkali reaction, liquid-liquid separation, no azeotrope.

4. How to choose the capacity of D-R-1010 D-R-1020 D-R-1050?

D-R-1010 rotating bottle is 10L, receiving bottle is 5L

D-R-1010 rotating bottle is 20L, receiving bottle is 10L
