Large Direct-Pure Water System, EDI

The Large Direct-Pure EDI lab water system produces Type II water from tap water directly. Resistivity of product water is above 5 MΩ·cm (25 ℃), which meets or exceeds Type Ⅱ water quality standard defined by ASTM, CAP, CLSI and ISO 3696/BS 3997, the European and U.S. Pharmacopoeia. The System is designed for users who need 400 to 1800 liters of Type II water per day.
