Description

Technical Field

[0001] The utility model relates to the field of design and use of a rotary evaporator, in particular to a rotary evaporator. Background Art

[0002] The rotary evaporator is electronically controlled. At the appropriate temperature of the flask, it rotates at a constant speed to increase the evaporation area. Through the coordination of various components, the evaporation is finally collected in the collection bottle through condensation.

[0003] At present, the main method for adjusting the height of the evaporation structure is to fix the evaporation structure on several sets of fixed rods and then change the height by adjusting the sliding seat. The speed is relatively slow, and if the hands slip and fall without good control, the collecting bottle and rotating bottle below may be damaged and broken. Therefore, the electronic control method will be more stable and safer.

[0004] In addition, the existing methods of heating the rotating bottle basically rely on the water bath at the bottom. Due to the inclined setting, the water bath cannot fully cover the rotating bottle, and the part not in the water will naturally cool down, so there is uneven heating. If the experimental environment temperature is low, the cooling will be faster. The rotating bottle can be showered with warm water from above, which can alleviate this problem to a certain extent and relatively increase the evaporation rate. Utility Model Content

[0007] Furthermore, the balanced heater includes a mounting seat, a mounting column, a mounting frame and a spray assembly, the mounting seat is mounted on the base, the mounting column is mounted on the mounting seat, the mounting frame is mounted on the mounting column, and the spray assembly is mounted on the mounting column and the mounting frame.

[0008] Furthermore, the spray assembly includes a fixing seat, a pump body and a spray head, the fixing seat is arranged on the mounting column, the pump body is installed on the fixing seat, and the spray head is penetrated and arranged on the mounting frame.

[0009] Furthermore, a thermometer is slidably provided on the mounting frame.
