About the product
The cobas c 111 analyzer is Roche Diagnostics’ analyzer for the in vitro determination of clinical chemistry parameters in serum, plasma, urine and whole blood (HbA1c). According to Roche, the instrument is a system that uses photometric analysis and is optimized for small workloads of up to 50 samples per day. Roche also states that the instrument is not intended for point-of-care testing. For brand information, the Roche Diagnostics page can be consulted.
System features
Sample handling is manual. Roche reports that primary and secondary tubes can be loaded continuously into 8 sample positions and that continuous loading of up to 60 cuvettes is possible. STAT prioritization is supported. Reagents are on exchangeable disks. Roche states that the same reagents, calibrators and controls are used with other cobas platforms and that a maintenance visit is needed once every 1.5 years.
