Back to product list
Detailed introduction

Milli-Q® Reference 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.

Milli-Q® water • Optimized purification

To obtain Milli-Q® ultrapure water quality, the purification sequence has been fully optimized. 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. A range of purification cartridges and Application Paks is available for you to select according to your applications.

Made only for Milli-Q® systems, Jetpore® virgin ion-exchange resin is used in all Milli-Q® purification cartridges. Selected for its exceptional performance, it can capture even the most weakly charged ions due to its kinetic capabilities. Both Q-Gard® and Quantum® cartridges also incorporate RFID technology. This provides instant visibility on cartridge parameters and also ensures a safe & optimal performance of your system, giving you full traceability.

Convenience • Simple dispensing & easy maintenance

Using the Milli-Q® Reference dispenser, 

·         Save time thanks to the volumetric function. It will automatically deliver the water volume that you requested. 

·         Effortlessly prepare solutions with the detachable, easy-to-handle dispenser. Its design has been conceived to fit the height and shape of all laboratory glassware.

These values (validated with Elix® feed water) are typical and may vary depending on the nature and concentration of contaminants in the feed water.

A report on conformity of Milli-Q® Reference water quality to Type 1 water quality as described by ASTM®, ISO® 3696 and CLSI® norms, and to Purified Water as described in USP and EP is available upon request.

Feed water
