General description

Milli-Q® Reference system with TOC indicator delivers Type 1 water customized to fit a broad range of research areas and makes ultrapure water conveniently available in any laboratory. It is designed to be fed from a pretreated water source (Elix®, RiOs, distilled or DI water).
In the Milli-Q® Reference system water purification sequence, the water is processed through Q-Gard® and Quantum® purification cartridges to reach a resistivity of 18.2 MΩ.cm (at 25°C) and a TOC value below 5 ppb. It then recirculates through a loop to the dispenser, where an Application Pak removes specific contaminants critical for your experiments.  
The system′s built-in Photooxidation UV lamp reduces the levels of organics for critical applications.  Further, a range of purification cartridges and Application Paks are available for you to remove specific contaminants such as bacteria, particulates, pyrogen, nucleases, endocrine disruptors, or volatile organic compounds (VOCs) to suit your applications.
The Milli-Q® Reference system graphic screen displays water quality and system status information to ensure that the system is properly operating, providing the best working conditions for your experiments.

Don′t forget to compare with our new Milli-Q® EQ 7000 system (ZEQ7000T0 and ZEQ7000TR), also available to meet your ultrapure water requirements.


Ultrapure water produced by the Milli-Q® Reference system is suitable for sensitive analytical applications such as chromatography (HPLC, IC) and elemental analysis (AAS, ICP); buffer and cell culture media preparation; molecular biology and biochemistry.
