In chemical synthesis experiments, rotary evaporators are often used for solvent recovery and product concentration treatment. By setting appropriate parameters such as rotation speed, heating temperature, and vacuum degree, excess solvents in the reaction system can be efficiently removed and high-purity products can be obtained. In the field of biomedicine, rotary evaporators are commonly used for solvent removal and sample concentration during drug purification and refining processes.

Rotary evaporators are mainly used for continuous distillation of volatile solvents under reduced pressure conditions and are commonly used experimental equipment in fields such as chemistry, chemical engineering, and biomedicine. Including the host (including heater and rotating shaft), evaporator, condenser, vacuum pump, etc. The heater in the host is used to control the temperature, and the rotating shaft drives the evaporator bottle to rotate; Evaporative bottles are used to hold liquid samples; The condenser is used to cool steam and collect liquids; Vacuum pumps are used to reduce the pressure inside the system and improve evaporation efficiency.
