Reliably pure water for results reproducibility & lab productivity

Milli-Q IX

Milli-Q® IX

For full confidence that water is not influencing your analyses, the Milli-Q® IX water purification system provides a reliable source of high-quality Type 2 pure water to feed your lab’s needs.

The Milli-Q® IX water purification system supports the needs of labs in regulated environments, where compliance, accuracy and efficiency are paramount (e.g. food & beverage, environmental and industrial testing labs; clinical labs; pharma industry). It also supports research and innovation laboratories to discover and develop the next big thing—faster (e.g. academia, research institutes, pharmaceutical research, biotech).

Watch the video below to see how the Milli-Q® IX pure water system delivers consistent-quality pure water, protection from contamination, and greater lab efficiency.

Consistent and Reliable Type 2 Pure Water Quality

Complementary and sustainable purification technologies—including our self-regenerating Elix® EDI module and mercury-free ech2o® UV lamps—ensure consistently high-quality pure water is always on hand. Final filters and polishers let you further match water quality to your specific application needs. Plus, with accurate and continuous resistivity monitoring directly on the dispenser’s touchscreen, you’ll always have full confidence in your pure water quality.

  • High-efficiency IPAK Gard® pre-treatment cartridge removes colloids, particles, free chlorine and minerals from tap water for protection of the reverse osmosis (RO) membrane to improved system performance
  • Advanced RO removes 95–99% of contaminants including ions, particles, bacteria and large organics. Its water recovery loop reduces water consumption and it adapts to your feed water temperature or conductivity to ensure a constant production flow rate
  • Our Elix® electrodeionization (EDI) module removes remaining ions for consistently superior quality pure water. The module continuously self-regenerates its ion-exchange resins via a small electrical field, eliminating the need for chemical regeneration procedures, reducing maintenance, and ensuring low and predictable running costs.

  • Mercury-free ech2o® UV lamps – Highest efficiency bacterial inactivation is achieved by mercury-free UVC LED technology emitting at 265 nm. These lamps are placed in the system's automatic recirculation loop and within the pure water storage tank for multi-targeted prevention of bacterial contamination.

Intelligent Pure Water Storage Tank

Discover our best-ever protection of stored pure water. This intelligent pure water storage solution provides multi-targeted protection from bacterial, particulate and CO2 contamination to safeguard water purity better than ever before:

  • Prior to water production, automatic rinsing of the RO membrane and the Elix® EDI module ensures that only the highest quality pure water enters the tank
  • A seamlessly integrated vent filter provides improved protection against airborne contaminants
  • The Automatic Sanitization Module (ASM) prevents bacterial growth and biofilm formation by regularly irradiating stored water and tank walls
  • An overflow sensor replaces the hydraulic overflow connection to a drain, eliminating this source of retro-contamination
  • Automatic recirculation of stored water through a bactericidal UV lamp preserves water quality in the tank and ensures that high-quality Type 2 water is always on hand and ready to use

Improved Sustainability Through Technology & Design


Innovative purification technologies and design features minimize the environmental impact of the Milli-Q® IX water purification system. Key sustainability features include:

  • The self-regenerating Elix® EDI module eliminates the need for chemical regeneration, avoiding chemical waste and associated waste shipment and disposal fees
  • Advanced RO recycles reject water, reducing water waste and overall water consumption
  • “Lab Close” mode minimizes water and energy consumption when your lab is closed for long weekends and vacation periods
  • Bactericidal ech2o® UV lamps are mercury-free
  • Less plastic has been used for manufacturing, packaging and shipping thanks to the more compact size of the system, tank and consumables

Simple and Intuitive Use that Supports Daily Lab Efficiency

You’ll always have convenient and easy access to fresh, pure water with our ergonomic and innovative E-POD® pure water dispenser:

  • Twist the dispense wheel or tap the touchscreen—even with gloves on—to adjust flow rate or set the volume.
  • Use the touchscreen to choose a dispense option, monitor water quality parameters, rapidly retrieve data, or control essential system functions.
  • Try Volumetric Dispense mode to automatically fill glassware to your set volume. Just push the button, screen or foot pedal (optional) to repeat.

Carefree Maintenance

Smart design features make the system easy to use and carefree to maintain:

  • Automated self-upkeep features include RO flushing and rinsing, EDI rinsing, recirculation loop, and tank UV sanitization
  • Automated alerts notify when consumables need replacing to avoid risk of impacting major components
  • Onscreen wizards guide you to perform simple maintenance and troubleshooting procedures in-house
  • Twist & Lock cartridge replacements can be confidently performed by anyone in the lab in a few minutes
  • Coordinated, once-a-year consumable replacements minimize hassle

Space-saving and Fexible Installation Options

The Milli-Q® IX system is designed to save valuable space with only the slim E-POD® dispenser on the bench. The compact purification unit and tank can be integrated under the bench, on the wall, or a combination of both to suit your requirements. A range of production flow rates (3, 5, 10, 15 L/h) and tank size (25, 50, 100 L) options are available to ensure your lab's needs are fully met. Two dispensers can be supplied by one system, with up to 5 m between the PODs. This way, scientists at distant benches—or even another lab—have access to purified water.

Advanced, Effortless Data Management

Simplified data management capabilities of the Milli-Q® IX system will move your lab notebook and user manual to the digital age. In a few clicks of the touchscreen you can download an individual Dispense Report, determine water quality over a specified time frame, allocate costs for shared resources, or create a customized report. Traceability is also ensured through the e-Sure tags on all consumables.
