Milli-Q^® SQ 2Series Water Purification Systems

Description

Milli-Q® SQ 2Series systems provide a flexible solution for delivering ultrapure water directly to laboratory benches. The core unit produces water with a resistivity of 18.2 MΩ·cm at 25°C. It features a mobile 3.5-liter 'Switch' tank that can be filled with reverse osmosis (RO) water at a make-up flow rate of up to 42 L/h, allowing for rapid refills. Ultrapure water is dispensed from a handset at a flow rate of up to 1.6 L/min, while RO water can be distributed via a gravity valve at up to 6 L/min. The system's compact design, with a footprint of approximately 22 x 27 cm per unit, requires only an electrical connection for operation, eliminating the need for a dedicated water feed at the point of use. Configurations vary by model (SQ 240, SQ 240L, SQ 240XL, SQ 240C, SQ 240CV, SQ 200P), supporting maximum daily usage from 10 to 100 liters. Key components include user-replaceable SQPAK™ polishing cartridges for ion removal and optional cartridges for reducing organic content. Operating weights range from 7 kg to 21 kg, and the system accepts 100-240 V AC, 50-60 Hz power.
