Description

Technical Field

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

[0002] Rotary evaporators are mainly used for concentration, crystallization, drying, separation and solvent recovery in the pharmaceutical, chemical and biopharmaceutical industries. The principle is to heat the evaporating flask at a constant speed under vacuum conditions, so that the material forms a large-area film on the flask wall and evaporates efficiently. The solvent vapor is cooled by an efficient glass condenser and recovered in the collecting flask, which greatly improves the evaporation efficiency. It is particularly suitable for the concentration and purification of biological products that are easily decomposed and denatured at high temperatures.

[0003] However, the prior art still has the following problems:

[0004] Firstly, the structure of the existing laboratory evaporator is relatively simple. The evaporating flask in the evaporator is generally fixed and does not have a mechanism for rotating the evaporating flask back and forth. Since the contact surface between the heating pot and the evaporating flask is limited, the bottom solvent in the evaporating flask is heated faster and the upper solvent is heated slower. The lack of a rotating mechanism makes it difficult for the evaporator to heat the solvent evenly, thereby reducing the evaporation effect of the evaporator.

[0005] Secondly, the existing evaporator does not have a lifting mechanism. When the evaporating flask is heated by the heating pot, the distance between the evaporating flask and the heating pot also affects the evaporation effect of the evaporator. The height of the evaporating flask must be adjusted according to the amount of solvent in the evaporating flask. The lack of a lifting mechanism makes it inconvenient to adjust the height of the evaporating flask, which reduces the convenience of using the evaporator.

[0006] In view of the above problems, the inventor proposes a rotary evaporator with uniform heating to solve the above problems. Utility Model Content
