The rotary evaporator increases the evaporation area and improves evaporation efficiency by rotating, while using a vacuum system to reduce system pressure and minimize energy loss. Modern rotary evaporators are usually equipped with functions such as digital control of vacuum pumps and digital display of heating temperatures, making operation more convenient and efficient. Rotary evaporators are widely used in fields such as chemistry, chemical engineering, and biomedicine, and can be used for recovering, evaporating organic solvents, and concentrating liquid samples.
