Rotary evaporator is a laboratory instrument used for distillation, separation, and concentration of liquid mixtures. It consists of a rotating flask that is heated by a water or oil bath, and a condenser that cools the vapors back to a liquid state. The rotary evaporator is a popular tool for chemistry, pharmaceuticals, and biochemistry laboratories due to its efficiency and versatility.

Mini rotary evaporators and small rotary evaporators are variations of the standard rotary evaporator that are designed to take up less space and be more portable. They are commonly used in small-scale experiments and in situations where laboratory space is limited.
