[0002] At present, high-purity liquid medicine or organic liquid is required in the chromatographic degradation production process. Therefore, it is necessary to prevent external impurities from mixing into the liquid medicine or organic liquid during the normal storage process of the high-purity liquid medicine or organic liquid. In one prior art, the device for storing liquid medicine or organic liquid is a sampling bottle. The sampling bottle is provided with several sampling ports. The sampling ports are relatively large. The liquid medicine is extracted from the sampling ports by a syringe and then transferred. Because the sampling ports of this sampling bottle are relatively large, external impurities will also enter the sampling bottle; furthermore, the liquid medicine in the sampling bottle will be splashed out during the process of moving the sampling bottle; in addition, when moving the sampling bottle, the mover will hold the sampling bottle with his hand and move it. This way of moving will inadvertently splash the liquid medicine in the sampling bottle onto the mover's hand. Summary of the Invention
