Do you know the specific preparation process of laboratory ultrapure water?

      In various biological experiments, both laboratory water and experimental water must be ultrapure water without any impurities and conductive media. Because some cells cannot provide correct data to the experimenter once they are polluted by water, it will have a certain impact on the experimental results. It can be said that in biological experiments, as long as water is used, it must be ultrapure water with no pollution, no impurities and no conductive medium. The laboratory ultrapure water device can well prepare ultrapure water. Let's talk about its specific preparation process.

The preparation process of laboratory ultrapure water device:

1. Pretreatment system→reverse osmosis system→intermediate water tank→coarse mixed bed→fine mixed bed→pure water tank→pure water pump→ultraviolet sterilizer→polishing mixed bed→precision filter→ Water Objects (≥18MΩ.CM) (Traditional Craft)

2. Pretreatment → reverse osmosis → intermediate water tank → water pump → EDI device → purified water tank → pure water pump → ultraviolet sterilizer → polishing mixed bed → Water Objects (≥18MΩ.CM) (New Craft)

3. Pretreatment →first-stage reverse osmosis→dosing machine (PH adjustment)→intermediate water tank→secondary reverse osmosis (positive charge reverse osmosis membrane)→pure water tank→pure water pump→EDI device&rarr ;Ultraviolet Sterilizer →0.2 or 0.5μm Precision Filter →Water Objects (≥17MΩ.CM) (New Process)

4. Pretreatment → reverse osmosis → intermediate water tank → water pump → EDI device → pure water tank → pure water pump → ultraviolet sterilizer → 0.2 or 0.5μm precision filter → ;15MΩ.CM) (new process)

5. Pretreatment system → reverse osmosis system → intermediate water tank → pure water pump → coarse mixed bed → fine mixed bed → ultraviolet sterilizer → precision filter → water objects (≥15MΩ.CM) (Traditional crafts)

The above is the specific preparation process of the laboratory ultrapure water device. I hope it can help you better understand the preparation process of ultrapure water in biological experiments and make better use of the equipment.
