The Cobas C 311 are used to analyze is called as the standalone system that would offer a consolidated testing from the broad menu of the clinical chemistry of applications. 

This analyzer would further have the capacity for the ion-selective electrode (ISE) the determination of sodium, and potassium, chloride in serum, along with the plasma, and urine.

Strength

• It has a first class performance system with a unique reagent concept.
• Over the present 130 assays and the applications available, including the following 
  • Drug of Abuse Testing (DAT)
  • Therapeutic Drug Monitoring (TDM)
  • The  specific proteins 
• Whole blood around the HbA1c1
• It also has a predictable turnaround time with intelligent sample workflow.
• It has an automatic determination of bilirubin and determines the sample integrity.
• It also has a highly reliable system with no preparation or mixing required.
• Unique reagent concept

Use

• The automated and discrete clinical chemistry analyzer is the one that is intended for in vitro quantitative or qualitative determination of- analytes in the body fluids.
• It has throughput of 300 photometric tests per hour.
• The samples that can be analyzed here are the Serum/plasma, urine, CSF
• This analyses is done under a pressure sensitive clot detection system
• It has a programmable and preventative QC system calibration of the stand-by cassettes. 
• In addition, it also has a measurement of the HbA1c levels in the whole blood that could also be performed, making it a flexible analyzer.
