Milli-Q® Direct

An ultrapure water system directly from tap producing RiOs™ and Milli-Q® water


In a single device, both RO (Type 3) water and ultrapure (Type 1) water are produced directly from potable water

Milli-Q® Direct at a glance

To obtain ultrapure water quality, tap water is purified to RiOs™ (Type 3) water: First, the Progard® cartridge provides a comprehensive pretreatment to extend the lifetime of the Reverse Osmosis (RO) membrane. Intelligent RO ensures the optimization of the water consumption, quality and a constant flow rate. Water is then irradiated by the optional bactericidal UV lamp. Depending on daily volume needs, different production flow rates are available (8 & 16 L/h).

The RO water is stored in a polyethylene tank designed to minimize risks of contamination during water storage. The vent filter provides effective protection against airborne contaminants

. The ASM, Automatic Sanitization Module, prevents biofilm formation

. Water can be either sourced through the tank front valve or sent by a distribution pump to feed instruments such as a glassware washing machine.

Water then passes through a long-life dual wavelength UV lamp, which ensures organic molecule degradation by photooxidation . Next, it is processed through the QPAK® purification cartridge to reach a resistivity of 18.2 MΩ•cm (25°C) and a TOC value below 5 ppb. Finally, it 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.
Selected for its exceptional performance, Jetpore® virgin ion-exchange resin is used in all Milli-Q® purification cartridges. Jetpore® is made only for Milli-Q®systems.Both Progard® and QPAK® cartridges 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® Direct 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.

Its graphic screen displays water quality and system status information to ensure your system is properly operating, providing the best working conditions for your experiments. A Quick Reference Guide located in the door of the Milli-Q® Direct system provides additional support for retrieving information. Easily replaceable cartridges, a long-lasting UV lamp coupled with timely service alerts, allows your system to run smoothly all year long. Millitrack® e-Solutions provide enhanced data management control, remote access capabilities to the system dashboard, and long-term electronic archiving for your Milli-Q® Direct. In addition, a complete range of Services, including Validation support, is provided by certified Field Service Engineers using calibrated equipment and Qualification Workbooks.

Quality certificates

For full confidence in your Milli-Q® Direct system, it is delivered with a Certificate of Calibration for the built-in temperature and resistivity meters, and aCertificate of Conformity ensuring that it has been built and tested fully assembled following internal Standard Operating Procedures. In addition all Milli-Q®consumables are delivered with their Certificate of Quality. The manufacturing site is ISO® 9001 v.2000 and ISO® 140001 certified.
