Confidence in Consistency

with Milli-Q® Lab Water Systems and Services


Consistent Lab Water Quality with Milli-Q® Water Purification Systems

Why do labs need consistent water quality? Because results accuracy and lab productivity depend on it. For this reason, Milli-Q® water purification systems and consumables are intelligently designed, quality manufactured and serviced throughout their lifetime to deliver confidence to your lab’s reliable output and uninterrupted operations.


Purification technologies produce & protect superior lab water quality

Our patented innovations ensure you always dispense water that is of consistent quality, and also aim to reduce the environmental footprint of water purification in the lab.

The quality and reliability of your analyses are assured by Milli-Q® lab water innovations

  • Elix® electrodeionization (EDI) module produces constant-quality pure (Type 2) water with no need for hazardous chemical regeneration procedures. This reduces maintenance and ensures low and predictable running costs.
  • E.R.A.® technology (Evolutive Reject Adjustment) in our high-flow systems optimizes water recovery from the reverse osmosis (RO) membrane, reducing water use by up to 50% vs. our previous generation of RO systems.
  • Intelligent tank design delivers multi-targeted protection from bacterial, particulate and CO2 contamination, safeguarding stored water purity better than ever before. Features include an airtight lid with a seamlessly integrated vent filter, overflow and level sensors, and an Automatic Sanitization Module (ASM) with a mercury-free UV LED lamp.
  • Mercury-free ech2o® UV lamps provide high-efficiency bacterial control and photo-oxidation of organic contaminants while eliminating mercury handling and associated regulated disposal management.
  • Lab Close mode effectively ‘hibernates’ your system when your lab is closed for extended periods, minimizing water and energy consumption while protecting water quality.

The Elix® electrodeionization (EDI) module produces constant-quality pure water. The graph demonstrates the superiority of Elix® EDI technology over systems using ion-exchange resin packs. When resin packs are exhausted, resistivity drops dramatically.

Always in Spec: Guarantee lab water purity with genuine Milli-Q® consumables

All Milli-Q® consumables have been validated to consistently produce the water quality expected and are delivered with Certificates of Quality.

Watch these videos to learn how powerful and patented purification media work together in our consumables to deliver and protect consistent water quality, and ensure the long lifetime of your water system:

To further ensure your water quality remains within specifications, we offer services and design features to support you to change consumables on time.

  • e-Sure tags: RFID technology on each consumable allows your system to monitor the status and lifetime of all on-board consumables. You’ll be alerted when cartridges need to be replaced and be assured of data traceability. Consumables’ status can also be monitored online via MyMilli-Q™ Digital Services.
  • Consumables Supply Agreements: With only 1 purchase order, receive automated deliveries of your required consumables throughout the year. You’ll save time and money and will be fully confident in always having the right consumables at the right time.
  • Easy, guided consumable changes: Onscreen wizards and ‘How to’ tutorials on YouTube provide visual step-by-step instructions to ensure any maintenance procedure is correctly performed.

Assured 24/7 monitoring, traceability & performance

It’s essential to know that your water purification system is continuously able to meet the specifications for your lab’s water quality needs. Milli-Q® systems and services provide you with 24/7 confidence in your water quality, at the moment of dispense, throughout the day, and even when you’re on vacation.

Water quality monitoring at dispense

Easily keep an eye on water quality parameters as you dispense. Product water resistivity and total organic carbon (TOC) can be monitored at a glance, directly on the dispenser touchscreen. These values are continuously monitored by our systems, so you can focus on your work at hand.

  • Resistivity monitoring: Our newest ultrapure (Type 1) systems contain precise in-line resistivity cells that accurately and continuously measure product water resistivity. The resistivity meter is built following ASTM recommendations and is able to pass the USP suitability test for resistivity meters. Certificates of calibration for the resistivity meter are delivered with our water systems.
  • TOC monitoring: Rapid and highly accurate TOC measurements are achieved by Milli-Q® IQ 7 series systems which contain our best-in-class online A10® monitor. This monitor is mercury free and its range (0.5–999.9) and precision pass USP and European Pharmacopeia suitability tests.

Online system & water quality monitoring

MyMilli-Q™ Remote Care online monitoring and service capability gives you 24/7 assurance that your water system is functioning correctly, and water quality is within specifications.
