NuZar U24 Water System


NuZar U24 Water System

NuZar water system set, U24 produces ultrapure water (Type I water) and RO water from tap water directly. Quality of ultrapure water meets or exceeds ASTM, CLSI, CAP, and ISO Type I water standards.

The NuZar water purification systems are compact and powerful. They are specifically designed for laboratories that demand a balance between cost of ownership and exceeding their purified water requirements.

The system is CE/RoHS certified. RephiLe provides full documents support to meet user’s GMP, GSP, GAP, GCP, GLP requirements.
