When preparing ultrapure water, the following points should be noted:

1. To produce ultra pure water, it should be prepared and used as needed to ensure the best water quality, as the water quality will deteriorate and be contaminated if left for too long after production.

2. Whether it is manual or automatic equipment, when producing pure water, we should pay attention to adjusting the valve, controlling the water flow, and avoiding splashing.

3. When using pure water, containers with relatively small openings should be used to minimize air entry into the bottle and reduce pollution.

4. Before using pure water, the container should be rinsed at least 3 times with pure water to prevent some pollutants from contaminating the pure water.

The above is an introduction to the precautions we need to pay when producing ultrapure water. Therefore, to ensure the quality of purified water, it is not only necessary to choose appropriate purified water equipment, but also to strictly regulate the operating procedures.
