Description

Technical Field

[0002] Rotary evaporator, also known as rotary evaporator, is an evaporation instrument widely used in laboratories. It is composed of a motor, a distillation flask, a heating pot, a condenser and other parts. It is mainly used for continuous distillation of volatile solvents under reduced pressure conditions. It is used in chemistry, chemical industry, biomedicine and other fields. When producing covalent organic framework materials, a rotary evaporator is usually required.

[0003] In the process of using a rotary evaporator, it is usually necessary to use a rotating device to rotate the rotary bottle, but the height of the rotary bottle is difficult to adjust, which leads to high limitations of the rotary bottle and cannot be adjusted according to the water level inside the water bath, affecting its use. At the same time, when the water level of the water bath is low, it is necessary to add water to the water bath, but the existing water adding method is partly through a pumping mechanism and an output pipe to add water, but the height of the output pipe cannot be adjusted, which leads to a high gap between the outlet of the output pipe and the water level, which easily causes water from the water bath to splash out, affecting normal use and being unfavorable for the use of the rotary evaporator.
