Laboratory Ultra-Pure Water Machine

The Xinrui Laboratory Ultrapure Water System is a water purification equipment for laboratory use, which removes all solid impurities, salt ions, bacteria, viruses, etc., from water through methods such as filtration, reverse osmosis, electrodialyzer, ion exchanger, and UV sterilization. It is a water treatment device.

Laboratory ultrapure water equipment is widely used in industries such as pharmaceuticals, electronics, chemical engineering, and biological and chemical laboratories. Laboratory ultrapure water systems typically produce both pure water and ultrapure water.

Product Features of Xinrui Laboratory Ultrapure Water System

1. Equipped with a complete purification unit, it uses tap water as the feed water and produces pure water and ultrapure water as output. It produces water of different standards to meet various laboratory water needs.

2. The new laboratory ultrapure water system produces 40 times more ultrapure water per unit than similar imported products, with a water production cost one-fiftieth of other products.

3. If the feed water quality is less than 2000 μs and hardness ≦450 ppm, the produced water quality can be stably maintained below 5 μs/cm, and the feed water utilization rate can reach 60%-80%.

4. Users can also quantitatively draw pure water and ultrapure water. Once the water volume is set, the ultrapure water system will automatically produce the appropriate amount of water. The water volume can be freely set from 10 milliliters to 200 liters, with quantitative accuracy up to ±2 ml.

5. Users can store and query data in real-time through the fully intelligent monitoring system, enabling trend analysis. The fully intelligent monitoring system supports multiple languages and multiple users, with separate data recording.

6. True-color LCD touch screen with a graphical human-machine interface ensures one-step operation and online information query. All monitoring data of the entire system are collected in real-time and can be viewed online without the need for external computer storage. Data storage capacity can exceed one year.

7. The reasonable placement of consumables in the purification unit and the plug-and-play design of components make calibration, maintenance, cleaning, disinfection, and sampling during system validation easier to perform.

The principle and steps for preparing ultrapure water with an ultrapure water system are generally as follows:

1. Feed water: Tap water, ordinary distilled water, or ordinary deionized water can be used as feed water.

2. Mechanical filtration: Removes mechanical impurities such as rust and other suspended solids through sand core filter plates and fiber columns.

3. Activated carbon filtration: Activated carbon is a broad-spectrum adsorbent that can adsorb gas components, such as residual chlorine in water, as well as bacteria and certain transition metals that can damage the reverse osmosis membrane, so they should be thoroughly removed.

4. Reverse osmosis membrane filtration: Filters out over 95% of electrolytes and macromolecular compounds, including colloidal particles and viruses. The removal of most ions significantly extends the lifespan of the ion exchange column.

5. UV digestion: Uses short-wave (180nm-254nm) ultraviolet radiation to decompose small organic compounds that are not easily adsorbed by activated carbon, such as methanol and ethanol, converting them into CO2 and water to reduce the TOC level.

6. Ion exchange unit: Mixed ion exchange beds are known to be the decisive means of removing ions from water. Obtaining ultrapure water through multi-stage mixed beds is not difficult. However, the TOC level of water mainly comes from the resin bed. Therefore, high-quality ion exchange resin becomes the key to success. High-quality resin refers to resin with excellent chemical stability, no decomposition, and free of oligomers, monomers, and additives. So-called "nuclear-grade resin" likely falls into this category. The higher the quality of the resin, the better.

7. 0.2μm membrane filtration removes particles in the water to less than 1 per milliliter (smaller than 0.2μm). The water produced after the above steps is ultrapure water, which should meet the requirements of various instrumental analyses, high-purity analyses, and measurements.
