Ultrapure Water System

The UltraPure series ultrapure water system is an efficient, convenient and high quality ultrapure water system, With 5.0 inch touch screen system, 3 way water quality sensor, 2 way flow sensor for quantified dispensing, single stage RO system and 2 pumps, The “RU” models are superior choice of ultrapure water for high grade experiments. With tap water inlet, its output ranges from 10 to 60 liters/hour. It can produce single stage RO water and ultrapure water. The single stage RO water´s ion rejection rate is more than 97%, and the ultrapure water´s resistivity absolutely reaches to 18.2MΩ.cm. It completely meets the highest grade I standard of ASTM, CAP, CLSI, EP and USP.

The “2RU” models adopt pretreatment and two-stage reverse osmosis configuration to product lab type III water quality, combined with the ultra-purification module to obtain ultrapure water with resistivity 18.2MΩ.cm. The perfect process and system performance is suitable to a variety of complex water sources, and the produced water can meet various experimental requirements. It is the best choice for high-end laboratory users.

Features and advantanges
  • ABS integrated molding engineering plastics are used to eliminate corrosion and rust.
  • The 5-inch large touch screen operation interface displays the real-time operation status and water quality is fully monitored. It has a USB interface, which supports data copy, download, printing and storage. It automatically record water quality data for five years to help laboratory data statistics.
  • Online 3-channel water quality monitoring, real-time monitoring of raw water/RO water, RO water/EDI pure water, UP ultrapure water quality, and can also detect water temperature, TOC value, water tank level and other data.
  • Fully automatic RO membrane anti-scale rinsing procedure to prolong the service life of RO membrane.
  • The ultrapure water circulating system can be started and shut down freely, maintaining a low level of bacterial contamination in the system.
  • Two-levels passwords to factory and users, system settings are protected by passwords to prevent unauthorized changes.
  • The lifetime of pretreatment, RO membrane, UV lamp and ultra-purification column can be set, showing the used and remaining time of consumables, and automatic reminders when consumables are due to be replaced to avoid water quality degradation.
  • Metered water intake function (timing: 1~60 Liters).
  • Pretreatment, RO membrane, and ultra-purification components adopt a modular independent structure, which makes system maintenance and filter element replacement more convenient, and conforms to GLP specifications, Using DOW original imported RO membrane and DOW ultra-purification resin, the combination of long life of RO membrance and high-quality water quality is realized.
  • Dual-wavelength (185&254nm) UV lamp assembly (imported lamp) can effectively sterilize, reduce TOC, and enhance the scope of application of the system.
  • (0.45+0.1)um imported PES polyethersulfone composite membrane terminal sterilization filter to ensure water quality sterility.
  • 5000DUF ultrafiltration assembly (original imported), effectively remove pyrogen (cndotoxin), can be used for precision cell cultrue and IVF.
  • The patented water tank is integrally molded with sanitary non-transparent plastic, top air filter, three-stage liquid level control and ultraviolet sterilization of the water tank to strictly control growth of bacteria in the water tank.
