Designed for analytical and research labs requiring Type I (up to 18.2 megohm-cm) water having total organic carbon (TOC) levels <5 ppb

Automatic continuous recirculation through the polishing loop maintains water quality, minimizes bacterial growth, and reduces rinse-up time. A TOC flush valve allows a small portion of the purified water to drain during automatic recirculation so a low TOC level is maintained. In-line dual UV reactor (185nm and 254nm wavelengths) reduces bacteria and organic chemicals. Stations include a power switch, LED water purity level display, and timed control dispensing valve which offers delivery up to 1.8L per minute. Steel cabinets measure 79.1Wx19.6Dx21.9Hcm (31¹/₈x7³/₄x8⁵/₈"). The overall height with bowls attached is 73.3cm (28⁷/₈").

Models 26301-855 and 26301-676 have a dispensing valve. Models 26301-856 and 26301-854 have the dispensing valve and a hand-held dispensing gun with 0.91m (3') recirculating line. Models 30181-412 and -414 dispense only HPLC water from the valve and only ultra-filtered (pyrogen-free) water from the gun. Dispensing module(s) are incorporated within the polishing station — no separate module is required.

Stations include pure polypropylene bowls for one activated carbon cartridge, two deionization cartridges, and one organic adsorption cartridge (not included). Required polishing kit 30181-398 includes one cartridge for each bowl.
