Description

Rotary evaporator with enhanced heat preservation effect

Technical Field

The utility model belongs to the technical field of chemical equipment, and particularly relates to a rotary evaporator capable of enhancing heat preservation effect.

Background

The rotary evaporator is a pharmaceutical experimental instrument which keeps a flask containing reactants and solvents to rotate continuously under the condition of decompression, so that the wall of the flask is heated uniformly, and a layer of solution film is attached to the wall of the flask, thereby increasing the evaporation area, accelerating the evaporation rate and evaporating the solvents which are easy to volatilize rapidly. However, during the continuous rotation of the flask, nearly half of the sphere always contacts air. In addition, leakage is also a common problem with rotary evaporators. Therefore, in the case of low-temperature weather, when rotary evaporation at a low rotation speed is performed, for example, when the evaporation amount is large, the flask contacts with cold air, and thus the constant temperature of the liquid film is affected to some extent. Therefore, the spherical surface of the flask, which is contacted with air, can be insulated, so that the constant temperature effect on the liquid film is improved.
