Rotary evaporator, also known as rotary evaporator used for sale or rotary evaporator, is an experimental instrument commonly used in chemical laboratories, mainly used for continuous distillation of a large number of volatile solvents under negative pressure conditions. In particular, the concentration of the extract and the distillation of the receiving liquid during chromatographic separation can separate and purify the reaction product. As the evaporator is evacuated, the boiling point of the solvent to be distilled is lowered. Usually, the components distilled from the sample are the target components in chemical research, such as extracting a natural component from organic synthetic samples. rotary evaporators under vacuum are mostly used to separate low-boiling components such as hexane and ethyl acetate, which are liquid at room temperature and pressure. In addition, through standardized operations, it is also possible to remove certain components contained in the sample.
 

The maximum capacity of the RE-2002 rotary evaporator is 2000ml, the speed is 5-120r.p.m, and the motor power is 25W. RE-2002 rotary evaporator realizes the ascending or descending of the main unit manually, the vertical high-efficiency condenser, and the interlayer has an ice container, which can quickly achieve the condensation effect. The rotary evaporator used for sale can rotate under constant temperature heating and negative pressure to form a thin film, evaporate efficiently, and then recover the solvent after cooling.

Product application scenarios：

Rotary evaporators under vacuum are mainly used for concentration, crystallization, drying, separation and solvent recovery in the pharmaceutical, chemical and biopharmaceutical industries. The principle is that under vacuum conditions, constant temperature heating makes the rotating bottle rotate at a constant speed, and the material forms a large-area film on the bottle wall, which evaporates efficiently. The solvent vapor is cooled by a high-efficiency glass condenser and recovered in the collection bottle, which greatly improves the evaporation efficiency. It is especially suitable for the concentration and purification of biological products that are easily decomposed and denatured at high temperatures.
