cobas c 311

analyzer for clinical chemistry 

The cobas c 311 analyzer is a stand alone system that offers consolidated testing from a broad menu of clinical chemistry applications. This analyzer has the capacity for ion-selective electrode (ISE) determination of sodium, potassium, and chloride in serum, plasma, and urine. In addition, measurement of HbA1c levels in whole blood can also be performed, making it a truly flexible analyzer.
