Analysis of the maintenance time of pure water obtained by ultrapure water mechanism

      Ultra-pure water machines are mainly used for the purification of laboratory water, which can remove impurities, salt ions, bacteria, viruses, etc. After the ultrapure water mechanism takes pure water, how long can pure water last? Let's talk about it in detail.

1. Please do not connect the hose after the terminal filter, and use the method of direct water intake to obtain ultrapure water with high purity.

2. When preparing high-purity chemical experiments, try not to store ultra-pure water in the bucket, because the bucket is used for a long time, and it is easy to breed bacteria and impurities, causing pollution to the ultra-pure water.

3. When taking water, let the ultrapure water flow into the container along the wall of the container, try not to generate air bubbles, which can reduce the pollution of air to the ultrapure water.

4. Drain all the RO water in the barrel to prevent pollution if the water is not used for a long time.

5. When the ultrapure water machine is not used for a long time, the pure water produced at the initial stage should be discharged to ensure the water quality.

6. The ultrapure water machine should be run through the water at least once every 7-10 days to ensure the water quality.

7. Do not place the water storage bucket in direct sunlight, the rise of water temperature will easily cause microbial reproduction, especially the translucent water storage bucket, which will cause algae reproduction due to the penetration of sunlight.

8. The purer the laboratory water, the less suitable it is to keep it for a long time. Because for the ultrapure water of 18.2MΩ.cm, after being placed for 1 hour, the resistivity will drop to 4MΩ.cm, and the PH will drop to about 5.7. Not to mention the pollution caused by the water environment and containers (such as dust in the air, leachables from contact with containers, and microbial contamination of water storage tanks).

The above is the time that the pure water obtained by the ultrapure water mechanism can be maintained. I hope it can help you make better use of this equipment for pure water production.
