[0002] The mobile phase waste liquid cylinder is a container for collecting the waste mobile phase generated during the liquid chromatography experiment. Since the mobile phase may contain various chemical substances, such as organic solvents, acids and alkalis, the waste liquid cylinder needs to have good corrosion resistance to prevent erosion and damage, ensure that the waste liquid does not leak, and avoid pollution and harm to the laboratory environment. In actual use, it is necessary to regularly inspect and clean the waste liquid cylinder to ensure its normal use and safety. At the same time, the collected waste liquid should be properly handled in accordance with regulations and cannot be discarded at will. For example, waste liquid cylinders made of acid and alkali resistant plastic or glass materials can be used, and different colors or labels can be used to distinguish different mobile phase types.

[0003] During chemical experiments, toxic and harmful gases such as methanol, ethanol, isopropanol, and n-hexane are often produced. Harmful gases will evaporate into the indoor air from the gaps in the bottle caps, making the indoor solvent smell strong, causing environmental pollution, and ventilation often cannot completely exhaust these gases. If they are not purified, they will cause safety hazards to experimenters. Utility Model Content
