The Direct-Q system is designed specifically for users with low water consumption, and can directly prepare pure water and ultrapure water from tap water to meet the different application needs of laboratories. Ultra pure water can be used for chromatographic separation of mobile phases, preparation of blank and standard solutions for spectrophotometry, spectroscopic or other analytical techniques, and preparation of biochemical experimental buffers. Pure water can be used for washing and rinsing conventional glassware. The Direct-Q 3 UV system is specifically equipped with an 185/245nm dual wavelength UV lamp to produce ultrapure water below TOC levels, especially suitable for applications sensitive to organic matter. The innovative small volume remote water dispenser makes it more convenient for you to fetch water.

Easy to install, no special installation program required, you can install it yourself. Compact design, easy to place on the laboratory bench and hang on the wall

Convenient water intake: The system height and shape have been specially designed to be suitable for various sizes of universal glass containers for water intake in the laboratory. Automatic circulation: When not taking water, the system can automatically circulate the ultrapure water inside to ensure stable water quality.

Information acquisition: The color graphic display is clear and bright, displaying all key information, including various system parameters, operating functions, and water quality status The system consumables are only "integrated" purification columns and terminal refiners, which are easy to maintain

High precision resistivity detector: adopting a unique sleeve design, low electrode constant (0.02cm-1), temperature sensitivity of 0.1 ℃, designed to meet the adaptability requirements of USP<645>, and displayed in both temperature compensation and non temperature compensation modes.

Ultra low organic matter: The system has a built-in dual wavelength (254/185nm) ultraviolet lamp that can reduce the TOC of the produced water to below 5ppb, to meet the experimental needs sensitive to organic matter, such as HPLC, LC, GC, or TOC analysis. The system outlet can be equipped with different terminal refiners to further purify your ultra pure water quality, thus meeting your different application needs.

Water quality indicators:
Ultra pure water (Grade I) production water quality*

Pure water (Grade III water) production water quality*

*Under normal operating conditions
**Use Millipak Express20 (0.22 μ m) membrane filter or Biopak ultrafiltration column as the terminal filter
***Using Biopak ultrafiltration column as the terminal filter
****Using EDS Pak filter column as the terminal filter

System parameters:

*If necessary, the system can be connected to another Millipore dedicated water tank
