How long can the water drawn by the ultrapure water machine be stored?

Release time：2021-06-10

The production speed of the ultrapure water machine is much higher than that of the traditional pure water production equipment, and it has become one of the indispensable laboratory water production equipment in various water industries. Although the ultrapure water produced by different ultrapure water mechanisms The water quality is different, but the maintenance of water quality is basically the same, so how long can half of the water from the ultrapure water machine be maintained? Let's talk about it in detail.

Generally speaking, water with higher laboratory purity is less likely to be stored for a long time. For ultrapure water of 18.2MΩ.cm, the longer it is placed, the more serious the decline will be. Usually, ultrapure water placed for 1 hour Its resistivity is reduced to 4MΩ.cm, and the PH is reduced to about 5.7. At the same time, due to the influence of the environment, the microorganisms in the water will grow rapidly.

Therefore, under normal circumstances, ultrapure water should not be stored for a long time after it is extracted, and should follow the use concept of instant use. At the same time, in order to ensure the quality of pure water and ultrapure water, we should pay attention to the following points when taking water:

1. The ultra-pure water machine should be flushed once every 7-10 days to prevent bacterial growth.

2. In the case of long-term inapplicability, it is necessary to drain all the water in the pure water machine and the water tank.

3. When the ultrapure water machine takes water, the initial pure water and ultrapure water should be discharged, and the water can be taken after the water quality is stable.

4. Do not place the water purifier and water storage tank in direct sunlight to prevent the growth of bacteria.

The above is the time that the ultrapure water mechanism can store after taking water. Users need to have a certain understanding of it in order to use the equipment better without wasting the pure water produced.
