rotateEvaporatorIntroduction

Rotary evaporator（Rotary evaporator）Mainly used for continuous distillation of large amounts of volatile solvents under reduced pressure conditions. Especially for the concentration of extraction liquid and distillation of the receiving liquid during chromatographic separation, reaction products can be separated and purified.Rotary evaporatorThe basic principle is vacuum distillation, which means that under reduced pressure, when the solvent is distilled, the distillation flask rotates continuously. Structure: The distillation flask is a pear shaped or round bottom flask with a standard ground mouth interface, connected to a pressure reducing pump through a highly reflux serpentine condenser tube, and the other opening of the reflux condenser tube is connected to a receiving flask with a ground mouth, used to receive the evaporated organic solvent. There is a three-way piston between the condenser tube and the pressure reducing pump. When the system is connected to the atmosphere, the distillation flask and the liquid receiving flask can be removed to transfer the solvent. When the system is connected to the pressure reducing pump, it should be in a reduced pressure state. When using, the pressure should be reduced first, and then the electric motor should be turned on to rotate the distillation flask. At the end, the distillation flask should be stopped first and then vented to prevent it from falling off during rotation. As a heat source for distillation, it is often equipped with a corresponding constant temperature water bath.
