Type II reagent grade water is defined by ASTM as water that has greater than 1 megohm-cm resistivity. CAP and NCCLS define Type II water as having greater than 2 megohm-cm resistivity.
Type II water is routinely used to wash and rinse glassware, either manually or in the final rinse cycle of an automatic glassware washer. All PREMIER CHEMICAL Type II Water Purification Systems produce purified water that exceeds ASTM, CAP and NCCLS specifications for Type II reagent grade water.
