The working principle of a rotary evaporator.
Add the liquid containing solute into the cylinder.
Activate the rotating device to start the cylinder rotating.
At the same time, turn on the heating system to transfer heat to the inner wall of the cylinder.
The liquid forms a uniform thin film during rotation and rapidly evaporates under heating.
The evaporated solvent vapor condenses into a liquid through the condenser.
The condensed liquid is collected through a condenser to obtain a pure solvent.
