ESR Analyzers automate the erythrocyte sedimentation rate test, which measures how quickly red blood cells settle in anticoagulated whole blood and helps detect inflammation, infection and autoimmune disorders. Optical or infrared detection tracks the boundary between plasma and settling red cells, replacing manual reading of Westergren tubes. Throughput of up to 80 samples per hour suits hospital, clinic and diagnostic labs, running EDTA or citrated blood tubes. Barcode scanning, touch screen operation and USB, LAN and LIS/HIS connectivity send results straight to patient records. Built-in calibration keeps readings consistent between runs and operators.
