Product Introduction for 2L Rotary Evaporator
The 2L rotary evaporator is a compact laboratory device used for solvent evaporation, purification, and concentration, especially for heat-sensitive materials. It operates by forming a thin film on the rotating flask under reduced pressure, enabling efficient and gentle evaporation. With a temperature-regulated water or oil bath and a multi-layer condenser, it ensures stable condensation and solvent recovery. This equipment is well-suited for chemical research, pharmaceutical development, academic experiments, and small-scale extraction tasks requiring controlled and reliable evaporation performance.
