Description
The Alifax® Erythrocyte Sedimentation Rate (ESR) Analyzer Series uses innovative capillary photometry to provide results in just 20 seconds, measuring red cell aggregation kinetics directly from EDTA blood tubes. These automated systems (Test 1, Roller 20PN/LC/MC, Jo Plus) eliminate manual dilution, reduce sample volume requirements, and comply with CLSI standards for rapid, accurate inflammatory diagnosis.
Key Features and Benefits
Speed & Efficiency: Results are provided in 20 seconds, significantly faster than traditional 30-60 minute Westergren methods.
Sample Handling: Uses EDTA tubes (standard for CBC), often removing the need for a dedicated ESR tube, and requires smaller blood volumes.
Technology: Employs capillary photometry to measure the intensity of red cell aggregation rather than conventional gravitational sedimentation.
Safety: Closed, automated, and in some models, semi-automated systems that reduce operator exposure to biological samples.
Workflow Integration: Features barcode readers and automatic washing routines to improve lab efficiency.
