High Purity DI Loop

As scientific and industrial technologies have advanced the requirements for high-purity water have increased. A water purification system combining pretreatment, polishing deionization and filtration is often required to produce ultrapure water. Type I reagent grade water must also be free of organics and bacteria with a resistivity rating of 18.3 megohms at 25° C (77° F).

The ARIES High-Purity D.I. Loop produces up to 4 liters (1.1 gal) of ultrapure water per minute by circulating feed water through three disposable cartridges. The first cartridge typically removes chlorine and organics (OR-1, Organic Removal Cartridge), while the remaining two cartridges typically remove ionizable contaminants (MR-1, Ultrapure Cartridge). A 0.2 micron final filter then removes bacteria and particles from the water.

The ARIES is an attractive, compact unit, designed to be mounted on a wall or set free-standing on a laboratory counter. A continuous-duty pump recirculates water through the cartridges to ensure constant water purity. A temperature-compensated resistivity cell with LED readout meter indicates water quality and when to change cartridges.

ARIES disposable cartridges provide long life, ease of installation and versatility. A complete cartridge change-out typically takes less than one minute.

The ARIES High Purity Loop can be used for a variety of applications including Pharmaceutical, Semiconductor and other analytical processes. Additionally, most cartridges can be returned to ResinTech for recycling. For further information on the ARIES High Purity Loop, or pre-treatment and post-treatment accessories, call ResinTech for your local Aries distributor.
