DxH 520 Hematology Analyzer
The DxH 520 is a 5-part differential closed tube hematology analyzer, designed to help your low-volume laboratory enhance patient care through increased productivity with reduced costs. The system delivers critical results the first time with accuracy, with as little as 375 µL tube fill-volume and an aspiration of only 17 µL—ideal for pediatric or difficult-draw samples. Technologists can experience safety without compromise with closed tube technology, providing optimal security against blood-borne pathogens. The DxH 520 hematology analyzer also has one of the smallest footprints in its class, uses only three reagents, and features a robust patient data and QC management package. Automated operational tasks promote ease of use, efficiency and uptime, freeing more time for patient care.

Announcement Winner: Best New Clinical Laboratory Instrumentation of 2018
The DxH 520 received the SelectScience Scientists' Choice Award® for Best New Clinical Product of 2018. We appreciate the support of all the clinical scientists and healthcare professionals worldwide who cast their vote for the DxH 520.
Discover how the DxH 520 hematology analyzer can transform your low-volume laboratory. With the DxH 520, you can:
Maximize laboratory productivity
- Optimize uptime with proven system reliability and an automated cleaning cycle
- Experience infrequent and simple reagent reloading—easily change all three reagents in less than five minutes
- Gain powerful patient and QC data management tools for paperless operations and to reduce clerical errors
- Discover a more efficient use of laboratory counter space with the analyzer’s compact footprint—smallest in its class
Deliver high-quality clinical results
- Ensure a more accurate differential with proprietary dynamic gating
- Improve flagging and reduce slide reviews while maintaining effective clinical sensitivity
Reduce overall operating costs
- Lower overhead costs by consuming fewer reagents and using less power due to a reduction in moving parts and a more intelligent, energy-optimizing design
- Eliminate disposal costs with cyanide-, azide- and formaldehyde-free reagents
