The Millipore Milli-Q Gradient is a reliable Water Purification system ideally suited for a number of lab applications including analytical chemistry, Mass Spectrometry and Ion Chromatography applications. This simple and easy to use Type 1 Water Purification system incorporates a seamless purification process, featuring a built-in TOC monitor along with water quality monitor alerting the user of when to change out filter packs.  The installed Quantum cartridge removes oxidation by-products and trace ions.  Lastly the purified water then passes through an Ultrafiltration module, that acts as a barrier to organic molecules, colloids and particles 5000 Daltons or greater. Located at point of use, the 3-way valve of this water purification system lets you direct the ultrapure water through a final filter that removes any remaining bacteria and particles greater than 0.22 µm in size, and prevents system contamination at point of use. The resulting ultrapure water helps data reproducibility, reduces fouling and baseline noise, giving you accurate research results.

This water purification system comes with a Quantum EX cartridge installed and has been fully refurbished to manufacturer’s factory specification.  Users may also purchase additional cartridges from Millipore, based on their applications needs.  Such cartridges available for this Water Purification system include Q-Gard and a series of Quantum cartridges which reduce particulates in water feed down to trace levels.  This water purification system has a number of modes accessible through the key pad, or are operated automatically by the microprocessor including system maintenance, TOC monitoring and alarm displays.
