How Long Can The Pure Water And Ultrapure Water Produced by The Ultrapure Water Machine Be Preserved?

How long can the pure water and ultrapure water produced by the ultrapure water machine be preserved? Due to the much higher production speed and efficiency of ultrapure water machines compared to traditional standards, they have become one of the essential equipment for laboratory pure water preparation. Different ultrapure water machines can produce different quality of pure water. Although laboratory ultrapure water machines have many brands and models, most of them are the same. So how long can the pure water and ultrapure water produced by pure water machines be preserved?

The production speed of ultrapure water machines is much higher than traditional pure water production equipment, and they have become one of the laboratory water production equipment in various water use industries. Although the water quality of ultrapure water extracted by different ultrapure water mechanisms varies, the maintenance of water quality is basically the same. So, how long can half of the water extracted from ultrapure water machines be maintained? Let's talk about it in detail below.

Generally speaking, water with higher purity in the laboratory is less likely to be stored for too long. For ultrapure water of 18.2 M Ω. cm, the longer it is left, the more severe the decrease. Generally, ultrapure water left for 1 hour can reduce its electrical resistivity to 4 M Ω. cm, and its pH drops to around 5.7. At the same time, due to environmental factors, microorganisms in the water can quickly breed.

Therefore, in general, ultrapure water should not be left for a long time after extraction, and should follow the concept of using it immediately after removal. At the same time, in order to ensure the quality of pure and ultra pure water, we should pay attention to the following points when taking water:

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

2. If it is not suitable for a long time, it is necessary to drain all the water in the pure water machine and water tank.

3. When using an ultrapure water machine to extract water, the initial pure water and ultrapure water should be discharged, and the water can only be extracted after the water quality stabilizes.

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

The above is the storage time that the ultra pure water mechanism can store after water extraction. Users need to have a certain understanding of it in order to better use the equipment and not waste the purified water produced
