Fully automated coagulation analyzer cobas® t 511

opticalPTAPTT

Overview
The cobas® t 511 coagulation analyzer is a fully automated, discrete coagulation analyzer intended for the in‑vitro qualitative and quantitative determination of coagulation analytes in human citrated plasma. Results assist in diagnosing coagulation abnormalities and monitoring anticoagulant therapy. The cobas® t 511 operates as a standalone instrument.
