About the product
The cobas c 303 analytical unit is Roche Diagnostics’ fully automated analyzer for clinical chemistry tests. According to Roche, the instrument is designed for various quantitative and qualitative in vitro tests and contains one photometric measuring unit and one ISE unit. The unit is used as the clinical chemistry and ISE unit in the cobas pure integrated solutions system. For brand information, the Roche Diagnostics page can be consulted.
System features
Photometric measurement is performed with a multi-wavelength spectrophotometer. The ISE unit uses the same sample pipettor. Roche reports that the menu includes more than 110 clinical chemistry applications covering proteins, enzymes, substrates, electrolytes, drugs of abuse, therapeutic drug monitoring and HbA1c tests.
