Yumizen H550

Hematology Analyzer

Full Walk Away Hematology Solution for Small Mid-Size Laboratories

The Yumizen H550 is a compact 6-Diff hematology analyzer with an auto sampling system which aims at providing a full walk away capability to a variety of clinical environments: hospitals, satellite labs, emergency care, small independent labs, doctors’ offices…

With safe sample management, the Yumzien H550 is able to deliver a one hour autonomy of 40 samples in racks. Additional benefits include; continuous loading, automatic sample mixing, positive identification of samples and a manual mode for STAT samples for both open and closed tubes. The latter will manage emergency and pediatrics demands for a variety of samples types.

Based on the innovative ‘3 reagent use’ technology with low consumption, the Yumizen H550 hematology system incorporates enhanced features with high added value for laboratories in terms of data management and traceability standards: flexible connectivity with both ASTM and HL7 communication standards and overlapping Quality Controls.

As new member of Yumizen H500 products family, the Yumizen H550 is tailored to improve operational efficiency in the laboratories and provide a rapid and comprehensive hematology diagnosis, to assist clinicians in the delivery of safe and effective patient care.
