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 accessible, innovative and completely scalable so that you can focus on your science.
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 and configure (available in Western European countries, USA, Australia, India and Singapore) the set up that best fits your space and user requirements, then easily expand with more modules as your lab expands.
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
