Barnstead NanoPure Diamond ultrapurifier

Designed to provide high resistivity, reagent grade water that exceeds ASTM Type I, CAP and NCCLS Type I standards. It uses a four-stage deionization process and a 0.2 micron filter to polish suitable feed water (distilled, deionized, or reverse osmosis) to produce water with a resistivity of up to 18.2 megohm-cm. Water resistivity is continuously monitored by a resistivity cell and displayed on a digital display.
