Milli-Q^® SR 240XL Purification System

To learn how Milli-Q® SQ 2Series water systems work and read a full overview, visit our dedicated page.
The Milli-Q^® SR 240XL water purification system delivers pure reverse osmosis (RO) water to one mobile SQ Switch 3.5 L tank and one SQ 50 L tank. The 3.5 L 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, the water system adapts to any lab configuration: the RO water production unit can be placed next to a potable water source, while unlimited ultrapure dispensing units 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. The SQ 50 L tank has a high-flow valve to directly feed lab equipment with pure RO water. It is useful in laboratories that require both pure and ultrapure water in substantial amounts.

This Milli-Q^® SR 240XL production station is part of 1 of 6 preset configurations (Milli-Q^® SQ 240XL) 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 pure RO water at up to 6 L/h directly from the SQ Switch tank base
• A direct feed for lab equipment: 50 L tank has a high-flow Gravity valve to dispense pure RO water at up to 12 L/h
• 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
• 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
• Individual Twist & Lock cartridge replacement, for each exhausted purification step, 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 the lab, thanks to the mobile SQ Switch tank
