THE ONLY SYSTEM THAT DELIVERS REAGENT GRADE WATER,WITHOUT WATERED-DOWN SERVICE. Milli-Q™ From Millipore. When you buy one, you get more than reagent grade water that exceeds standard purity specifications, you get support and service that exceed what the competition can offer. Because other systems are mainly sold through distributors; and distributors simply don't have the staff, the expertise, and often the motivation to help in your application. In contrast, Milli-Q is sold to you direct. And the service you receive from the staff at our network of support centers is total. From the very beginning, you'll have on-site
technical assistance, plus help in planning future costs for upkeep. But more about the Milli-Q itself. The system takes water that's been pretreated (deionization, distillation or reverse osmosis) and processes it through an activated carbon cartridge to remove dissolved organics; then through two strong acid/ strong base mixed-bed ion-exchange cartridges to remove dissolved inorganics; and finally, through a Twin-90 membrane filter to remove all microorganisms and particles larger than 0.22 microns. The result is the purest water available. And a resistivity meter that comes with the
system makes it easier to see that it stays that way. The cartridges and filter units are disposable. And can be replaced in a couple of minutes without the use of tools.
