The URIT-5500 is a five-part-differential automatic hematology analyzer with a throughput of up to 110 samples per hour (auto) and 100 samples per hour (manual). URIT-5500 Auto Hematology Analyzer uses helium-neon laser for the flow cytometry system. Through calculations of different angles via laser scatters, the instrument provides complete analysis including cell size, granularity and complexity.
