Description

Technical Field

[0001] The utility model relates to the technical field of rotary evaporators, in particular to a rotary evaporator with adjustable height. Background Art

[0002] A rotary evaporator is a chemical laboratory equipment, which is mainly used to study compounds in organic solvents and realize the functions of material separation and concentration. A rotary evaporator is usually composed of three main parts: a distillation flask, a rotary motor and a vacuum pump. The rotary motor is used to drive the distillation flask to rotate, so that the solvent in the distillation flask forms a thin film on the inner wall of the distillation flask to increase the evaporation area. The vacuum pump is used for vacuum suction operation to promote the internal vacuum environment. After the pressure is reduced, the boiling point of the substance will also be reduced accordingly, making the evaporation process easier.

[0003] At present, when using the rotary evaporator on the market, although it can slide up and down along the corresponding rod body to achieve the height adjustment operation, the operation process is performed manually. After manual adjustment, it is necessary to continue to tighten and fix it with the fastening bolts. The manual operation is relatively troublesome and brings inconvenience to the user. In view of this, we propose a height-adjustable rotary evaporator. Utility Model Content
