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.

• 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

  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 and 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

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.

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.

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.

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.
