1L-100L Rotary Film Evaporator is the most commonly used evaporator in the laboratory for concentration, alcohol recovery,and solvent removal.
Due to its economical price, the rotary evaporator is very popular among customers.
Although its evaporation efficiency is not as high as that of the rising film or wiped film evaporator, the rotary evaporator also has many ways to improve efficiency, such as:
These methods can improve the evaporation and recovery efficiency of rotary evaporator.

XINCHEN Rotary evaporator capacity has 1L,2L, 5L, 10L, 20L, 30L, 50L,100L.
