Chemray® 420

The Chemray 420 Auto Chemistry Analyzer is a fully automated, high-throughput clinical chemistry analyzer designed to provide efficient, precise, and reliable results. With a throughput of up to 360 tests per hour and 540 tests per hour with ISE (K, Na, Cl), this random-access analyzer is ideal for medium to high-volume laboratories. It supports STAT sample priority, multi-reagent chemistry processing, and bi-directional LIS interface (HL7) for seamless laboratory integration.
