China rotavapor 2L rotary evaporator practice test under vacuum condition, through equipped with vacuum pump, low temperature circulating device, vacuum controller.
When rota evaporator system vacuum is well controlled bu vacuum controller, solvent boiling point will decrease, heating evaporation or cooling receiving also could be efficiency going to max.
Let's see how receiving rate reach to 99% by TOPTION "2L rotary evaporator sets":

- The data is collected in test of 1-2L TOPTION Rotary Evaporator. Condition: RT22℃, Rotation flask 1000ml, Charging volume 500ml.
- To get max vaporization speed, heating temperature shall be 40℃ higher than that of boiling temperature of solvent.
