The rotary evaporator is developed using the principle of constant temperature
heating and thin film evaporation under vacuum negative pressure conditions.
The rotary evaporator uses stepless speed regulating motor to make the rotary
flask rotate at a constant speed. The material forms a large and uniform film on
the inner wall, and then the rotary flask is uniformly heated by an intelligent
constant temperature water bath. It evaporates at high speed under vacuum
conditions. Then the solvent vapor is cooled by glass condenser and recycled
into a collection flask, greatly improving evaporation efficiency
