[0025] The working principle of this utility model is as follows:

[0026] In use, the experimenter first pushes the push rod 5 to rotate the moving wheel 2, moving the base 1 and the evaporator to the designated location in the laboratory. Then, the moving wheel 2 is locked in place. According to the experimenter's height, the fastening screw 17 is loosened, and the support wood 19 is moved up and down to adjust the height of the evaporator. The solvent to be evaporated is filled into the rotating flask 14, and the rotating flask 14 is clamped onto the power end of the rotary evaporator 13. At the same time, the rotating flask 14 is placed inside the heating water bath 15. The operation panel 3 is pressed to control the heating water bath 15 to heat and control the rotary evaporator 13 to drive the rotating flask 14 to rotate, achieving constant temperature rotary evaporation of the solvent. The evaporator enters the condenser 10, and the evaporated liquid is cooled and condensed by the coolant flowing through the condenser tube 11. The liquid falls into the collection bottle 18 for collection, realizing the effective evaporation and use of the evaporator.
