losed storage: Sealed containers are an ideal choice for storing ultrapure water as they prevent particles and gases from entering the water. Glass bottles are usually considered the best choice as they do not release any impurities into the water, but care should be taken when using them to avoid collisions and breakage. Polyethylene (PE) bottles are also a common choice, but it is important to ensure their quality is satisfactory to avoid releasing impurities.

2. Nitrogen protection: Nitrogen is a harmless and chemically stable gas that can be used to replace oxygen in the air. By injecting nitrogen, the impact of oxygen on ultrapure water can be reduced, preventing oxidation and other chemical reactions from occurring. Normally, nitrogen gas is pushed into the bottom of the container and air is expelled through the top of the container to ensure that a nitrogen atmosphere is maintained inside the container.

3. Avoid light: Ultra pure water is sensitive to light, which can cause some chemical reactions to occur, thereby affecting the purity of water. Therefore, ultrapure water should be stored in opaque containers to reduce the entry of light. Avoid exposing the container to direct sunlight and store it in a dark or dark box as much as possible.

4. Keep clean: It is very important to keep the operating environment and tools clean to reduce impurities in the air entering ultrapure water. When operating ultrapure water, it is recommended to operate in a dust-free room or environment to minimize the presence of particulate matter. Regularly clean the operating table, containers, and tools, and use cleaning agents and purified water to ensure a dust-free and impurity free environment.
