Milli-Q® SR 240 Water Purification System
General Description
To learn how Milli-Q® SQ 2Series water systems work and read a full overview, visit our dedicated page.
The Milli-Q® SR 240 water purification system delivers pure reverse osmosis (RO) water to a mobile SQ Switch 3.5 L tank. This tank is easily transferred to the Milli-Q® SQ 200 Purification System to produce fresh ultrapure water anywhere in the lab. Thanks to the mobile SQ Switch tank, this water system adapts to any lab configuration: the RO water production unit is placed next to a potable water source, while unlimited ultrapure dispensing modules can be positioned anywhere in the lab or building with an electrical outlet. This allows for a flexible installation that can be easily adapted and scaled according to changing lab requirements.

Features and Benefits
The Milli-Q® SR 240 production station is part of 1 of 6 preset configurations (Milli-Q® SQ 240) available for the Milli-Q® SQ 2Series, which provides full autonomy to users and is adaptable to lab requirements and evolutions. This RO water production station provides:
- Fast (as little as 6 min) refilling of the mobile SQ Switch tank with freshly produced pure RO water thanks to the high-flow RO cartridge (up to 42 L/h); RO water recovery loop saves 50% of the rejected water; High performance maintained by automatic rinsing of RO membrane.
- Gravity Valve (optional) lets you dispense RO water directly at up to 6 L/h from the SQ Switch tank base.
- Compact setup and self-guided installation manual and videos let you plug the system wherever is convenient for your lab activity and move it later if needed.
- Unlimited scalability with one pure RO water production station able to feed multiple autonomous Milli-Q® SQ 200 ultrapure dispensing modules. This supports lab activity expansion while limiting budget investment.
- Individual Twist & Lock cartridge replacement simplifies maintenance and limits running cost.
- Compact size plus water and energy savings support lab sustainability efforts.
When combined with the autonomous Milli-Q® SQ 200 ultrapure water dispensing module, labs benefit from:
- Simple, manual handset dispensing that allows any new or untrained user to deliver ultrapure water at variable flow rate, from up to 1.6 L/min to drop by drop.
- Reliable 18.2 MΩ·cm resistivity ultrapure (Type 1) water quality, indicated at a glance by a colored LED, and TOC is reduced by an integrated photo-oxidation UV lamp.
- Freshly dispensed ultrapure water available anywhere, in or out of the lab, thanks to the mobile SQ Switch tank.
