Automated immunoassay analyzer DxI 9000

for clinical diagnosticchemiluminescencechemiluminescence immunoassay

Overview
Designed for clinical laboratories, the DxI 9000 Access Immunoassay Analyzer delivers high-sensitivity, high-precision chemiluminescent immunoassay testing with PrecisionVision™ machine vision and integrated automation connectivity. The platform supports a broad and expanding assay menu and is intended for professional laboratory use.

Key features and advantages

• Highest percentage of Six‑Sigma‑verified immunoassays to reduce repeat testing and increase result confidence
• PrecisionVision™ machine vision optics enabling expanded detection and menu growth
• No-daily-maintenance workflow elements to minimize routine interventions
• Integration-ready with total laboratory automation and connected solutions
• Onboard guidance and troubleshooting via SimpleSolve instrument-guided support
• Patented luminometer with expanded linear range for low- and high-signal detection

Clinical and workflow capabilities
Engineered for high throughput (up to 450 tests/hour) and sensitive assay performance while supporting low sample volumes. Dedicated low-volume pipetting enables sample inputs down to 2 μL and disposable tips reduce carryover. Integration with Beckman Coulter automation supports rapid sample characterization and intelligent processing.
