Innovative Technologies Lead to a Comprehensive Upgrade of Laboratory Pure Water System Technology

Advanced Process Technology

Pretreatment System: Employs a pretreatment and testing device for ultrapure water production, using a composite-encapsulated preprocessor similar to that used in laboratory pure water systems.

Reverse Osmosis Purification System: Utilizes reverse osmosis technology. The RO membrane achieves a removal rate of over 99% for high-valence ions, colloids, bacteria, and organic matter with a molecular weight greater than 300 Dalton. It removes low-valence ions (Na+, K+) at a rate of 90-95%. The conductivity of the RO pure water used in the reverse osmosis pure water system is typically ≤5μS/cm, meeting the national laboratory Class III water standard. This is the most economical method for effectively removing 90-99% of impurities and is also the best pretreatment method for ultrapure water systems. Patented for its water discharge exceeding standards device.

Post-treatment Ultrapurification System: Utilizes a patented new laboratory pure water system technology, employing a dual-wavelength ultraviolet digester to comprehensively eliminate and rapidly decompose residual organic matter in the water.

Laboratory Pure Water System Features

Operating Interface

1. Fully Chinese menu LCD display, membrane touch switch, fully realizing human-machine interaction;

2. Saves water intake history through dedicated software, monitors product water quality in real time, and can output RS232 for direct printing, meeting GLP requirements;

3. Produces two types of water in one machine: Grade 1 and Grade 3 laboratory water, enabling differentiated water quality in the laboratory;

4. PLC fully automatic control, low water pressure alarm, automatic shutdown protection in case of water outage/power failure/tank full;

5. Reservation function. 

6. Water dispensing functions, including timed and quantitative dispensing, save time and reduce waiting time.

7. Simultaneous online monitoring of RO pure water conductivity and UP ultrapure water resistivity/water temperature.

8. Fixed-quality water dispensing function (1-18.25MΩ.cm) ensures consistent water quality for each test, avoiding experimental errors caused by water quality; it also prevents the loss of large amounts of pure water due to substandard water quality, saving water resources and reducing operating costs.

9. The main unit automatically reminds you when water quality deteriorates and consumables need replacement.

RO pure water conductivity and UP ultrapure water resistivity/water temperature online monitoring ... Reliable Quality

1. UPU ultrapure water systems feature a zoned design for water/electrical circuits and high/low voltage circuits, facilitating maintenance and providing a high level of safety protection.

2. Major components are original imports, and materials meet US NSF and Water Quality Association standards.

3. Certified by ISO9001:2000 international quality system, the factory employs strict quality control processes, ensuring reliable and stable product quality.

4. In addition to major components, the PE pipes and quick-connect fittings used in UPU ultrapure water systems are all original imported products of the same brand (DM), ensuring reliable quality, preventing leaks, and avoiding secondary contamination of the pure water.

5. All internal standard parts in UPU ultrapure water systems are made of stainless steel, ensuring that they will not rust and affect water quality and service life even in humid environments.

6. UPU's dedicated testing laboratory ensures that every UPU ultrapure water machine undergoes simulated testing in a water quality environment similar to that of the customer's laboratory before leaving the factory, making the equipment more suitable for the customer's operating environment;

7. After-sales service outlets are located in major provinces and cities nationwide, providing customers with installation and commissioning services, regular after-sales maintenance, and consumable replacement services. 24-hour on-site service is available in central cities, and 48-hour service is available in county-level cities.

Cost Savings

1. Automatic flushing of the internal RO and UF systems extends the lifespan of consumables;

2. For customers with high water consumption, a floor-standing design is adopted. The floor-standing ultrapure water machine features a purification tank where customers can replace the resin themselves, replacing the disposable purification column of traditional benchtop machines, saving 60%-70% on annual consumable costs.

3. UPU's dual-stage reverse osmosis system design can directly produce pure water with a resistivity of 0.5-1 MΩ·cm from tap water, with user water treatment costs of only 0.05 yuan/liter.

4. For high-salinity areas such as Shanghai and northwestern China, UPU employs an enhanced pretreatment system (or fully automatic water softener) for deep pretreatment desalination, effectively reducing the desalination burden on subsequent treatment processes and lowering consumable costs by 50%.

According to market research reports, UPU's market share is second only to Millipore in the US, ranking first among domestic brands of laboratory water purifiers. With its philosophy of providing high-quality products and benefiting users, UPU has won the recognition of a wide range of customers.
