Large capacity rotary evaporator (20L)

A large capacity rotary evaporator (20L) is a commonly used separation and concentration equipment, mainly used for the separation, solvent recovery, and concentration of liquid mixtures. By using the liquid inside the rotating bottle to form a thin film under heating, the solvent quickly evaporates, thereby achieving the separation and concentration of substances. It usually consists of components such as a heating bath, rotating bottle, vacuum system, condenser, and collection bottle. The heating bath provides heat, the rotating bottle contains the liquid mixture to be processed, the vacuum system is used to reduce system pressure, the condenser is used to condense the evaporated solvent, and the collection bottle is used to collect the concentrated solution.

　Large capacity rotary evaporator (20L)The working process:

-The liquid mixture is added to a rotating bottle.

-The rotating bottle is placed in a heating bath, which provides heat to rapidly raise the temperature of the liquid mixture.

-At the same time, the vacuum system is activated to reduce system pressure and promote rapid evaporation of the solvent.

-The solvent vapor condenses into a liquid through a condenser and is collected in a collection bottle.

-The concentrated solution remains in the rotary flask, completing the concentration and separation process.
