Milli-Q SQ 2Series

Every lab bench in need can now easily access freshly purified ultrapure water—even distant benches without feed tap water. New Milli-Q® SQ 2Series water purification systems are simple, robust, innovative and completely scalable so that you can focus on your science.

Category: Tag:

A choice of configurations combined with its modular design makes the system adaptable and scalable to nearly any lab or building set up. Simply select the set up that best fits your space and user requirements, then easily expand with more modules as your lab evolves.

Features common to nearly all Milli-Q® SQ 2Series system configurations include:

  • – Rapid pure reverse osmosis (RO) water production at a rate of up to 42 L/h, filling the 3.5 L Switch tank in as few as 6 min
  • – Ergonomic dispensing of ultrapure water, from 1.6 L/min to drop by drop
  • – Easily expand capabilities by adding autonomous ultrapure water dispensing modules

How Milli-Q® SQ 2Series Purification Systems Work: 

Thanks to its completely scalable design, any lab bench with an electrical outlet can easily access fresh purified 18.2 MΩ∙cm ultrapure water.

  1. Rapidly fill the 3.5 L Switch tank with reverse osmosis (RO) water in as few as 6 minutes.
  2. Easily carry the Switch tank to your science.
  3. Dispense freshly polished 18.2 MΩ∙cm ultrapure water at any bench.
  4. Repeat as needed.

Unique Innovations

The system has patents pending for 8 technical and design IP filings, including:

  • – Mechanical intelligence that allows for intuitive filling with just the push or pull of your thumb
  • – Two-way multi-lumen tubing that recirculates water to secure the quality of ultrapure water
  • – Exceptionally high-flow RO membrane (up to 42 L/h) refills the Switch tank in as few as 6 min
Ultimate Simplicity

The system is easy and intuitive to install, operate and maintain for any user.

  • – Proven, do-it-yourself self-installation (~30 min)
  • – Universal interface
  • – Ergonomic dispensing
  • – Mobile, transparent tank
  • – Twist & Lock cartridge changes
  • – No need to replace the UV lamp
Ultra Compact

The uniquely small size leaves space for your science at any lab bench.

  • – System units have the same footprint as a sheet of paper: 22×27 cm/unit.
  • – Only an electrical outlet (and no water inlet) is needed to dispense ultrapure water.
Unlimited Scalability

Select the configuration that best fits your space and user requirements, then easily expand with unlimited ultrapure water dispensing modules as your lab evolves.

Reliable Quality

Proven Milli-Q® water purification technologies mean you can trust your system is always ready to dispense consistent quality 18.2 MΩ∙cm @25 oC ultrapure water.

  • – High efficiency removal of ions down to trace levels with SQPAK™ Quanta polishing cartridge
  • – For organic-sensitive applications, SQPAK™ TOC Quanta cartridge contains activated carbon
  • – Pure RO water quality is maintained by regular rinsing of the RO membrane
  • – Choice of final filters can match your specific application needs

A Greener Alternative

Milli-Q® SQ 2Series systems are developed to deliver high-quality ultrapure water at multiple locations with a reduced environmental footprint compared to previous generations of water puirification systems.

  • Consumes less electricity thanks to simplified design, minimized electronics, and optimized stand-by mode (where most energy is consumed)
  • Consumes less water during manufacturing and use
  • Limited material requirements if 2 or more dispensing locations thanks to a modular design
  • Packaging consists of 100% recycled cardboard with sustainable forestry certification, and protective inserts made of PE with 50% recycled content
