Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical testing technology, specifically a distillation apparatus for pharmaceutical testing. Background Technology

[0002] In the process of drug testing, it is often necessary to separate and purify drugs to obtain purer samples for analysis. Rotary evaporators form a thin film by rotating the bottle, increasing the evaporation area. At the same time, the pressure inside the system is reduced by the action of a vacuum pump, thereby lowering the boiling point of the solution and making the evaporation process faster and more efficient. This efficient evaporation and purification method helps to remove impurities from drugs, improve the purity of the sample, and thus ensure the accuracy of drug testing.

[0003] During the operation of the rotary evaporator, the collection bottle is used to receive the evaporated organic solvent.

[0004] However, when the collection bottle is connected to the condenser only by a clamp, its bottom lacks a stable support structure, which makes the collection bottle prone to losing balance when subjected to external forces or changes in internal pressure. Once the collection bottle falls off, it will not only waste solvent, but may also cause pollution and harm to the experimental environment and operators.

[0005] Therefore, we propose a distillation apparatus for drug testing. Utility Model Content
