General description

Milli-Q® EQ 7000 water purification system delivers up to 300 L of ultrapure water per day on demand from purified water, such as from a Milli-Q® IX pure water system (e.g.ZIX7003T0C) stored in any Milli-Q® storage tank (e.g.TANKA050), or delivered by a pressurized loop fed by a centralized pure water system such as a Milli-Q® HX system (e.g. ZLXL51040).

A range of intelligent design features and technological innovations make the system easy to use and reduce its environmental footprint compared to the previous generation Milli-Q® Reference system.

The purification system works in combination with:
  • A large, 7-inch (~18 cm) touchscreen interface that allows intuitive system control, rapid data access, and at-a-glance quality monitoring.
  • The ergonomic Q-POD® dispenser that provides 3 flow rates, ‘Check & Dispense’ lights, and final polishing adapted to specific application needs.


This high-quality Milli-Q® ultrapure water system is flexible, intuitive, and reliable. Ultrapure water produced by this system is used for sensitive analytical techniques including HPLC, UHPLC, IC, and other types of chromatography, as well as for elemental analysis techniques such as AAS and ICP-MS.

It is also recommended for use in life science areas such as cell biology, molecular biology, biochemistry and innovative detection methods.

Features and Benefits

  • Delivers ultrapure water from a pure water source.
  • IPAK Meta® and IPAK Quanta® polishing cartridges remove ions from pure water down to trace level.
  • The Q-POD® dispenser offers agile delivery of water at 3 manually adjustable flow rates (< 2 L/min).
  • ‘Check & Dispense’ lights on the Q-POD® arm ensure system readiness and an optimal dispense.
  • One-touch volumetric dispensing, from 100 mL to 25 L, in 100 mL increments.
  • Delivers consistent low total organic carbon (TOC = 5 ppb) ultrapure water.
  • A user-friendly, intuitive HMI touchscreen simplifies system use and data access.
  • At-a-glance quality monitoring gives essential water quality information (resistivity, temperature, TOC indication, and water circulation status) on the touchscreen interface.
  • The inline TOC indicator measures TOC at the point of use. The measure appears on the display 90 seconds after each dispense.
  • e-Sure tags present on all system consumables including Application POD-Paks give full data traceability.
  • Flexible, space-saving installation options: on or under the bench, or wall mount.
  • A convenient hands-free dispensing foot pedal option reduces the risk of contamination.
  • Lab Close mode minimizes water and energy consumption when the system is not used for extended periods.
  • Easy and carefree maintenance: Automatic alerts notify the need for cartridge replacement.
  • Manufactured in an ISO 9001 and ISO 14001 certified production site.
  • Select from a full range of services, including time-saving MyMilli-Q Digital Services.


  • A specific country box with the user manual in the local language and a power cord adapted to the local electrical network needs to be ordered in addition to this catalog number.
  • The indicated price currently corresponds to the above catalog number only; it is subject to change at any time without notice.
  • This catalog number contains the water purification unit and the HMI touchscreen.
  • This catalog number does not include the ultrapure water Q-POD® dispenser, consumables, accessories, and other services that may be required for the installation and the correct operation of the water purification unit over time.
  • Because our customers each have specific purified water needs, we recommend that you have your purchase validated by one of our specialists. We remain at your disposal to advise you, do not hesitate to Contact Us!
