The cobas® c 303 analyzer is an essential module of Roche’s cobas® pure integrated solutions, designed for in vitro diagnostics (IVD). It is a fully automated, high-throughput photometric analyzer for performing clinical chemistry and electrolyte testing. The cobas® c 303 combines both clinical chemistry and electrolyte testing capabilities within a compact footprint of just 1.2 m² (in chemistry-only configuration).
Engineered to deliver excellent performance and simplify daily laboratory workflows, the cobas® c 303 is part of the cobas® pure system, integrating clinical chemistry, immunoassay, and electrolyte testing into one compact platform. This system significantly reduces manual intervention, saving valuable operator time.
Key Features:
-
Automatic Calibration (cobas® AutoCal): Reduces calibration workload by 56%, saving up to 105 hours annually, with automatic reagent lot calibration for most chemistry tests.
-
Minimal Maintenance: Daily manual maintenance tasks take just 5 minutes.
-
Ready-to-use Reagents: Utilizes cobas® c pack green reagents, requiring no preparation, mixing, waiting, or uncapping. These reagents are highly stable on the analyzer (average 137 days, with 57% stable for up to 6 months).
-
Assay Integrity & Safety: Features include non-contact ultrasonic mixing to prevent contamination, thorough probe rinsing with deionized water after each sample, special cleaning programs for high-sensitivity assays, and automated detection of liquid levels, clots, and air bubbles. Automatic rerun and dilution functions ensure reliable results.
-
Proven Reliability: The cobas® pure solution offers >99% uptime, backed by a track record of over 75,000 cobas analyzers installed worldwide.
Standardization and Efficiency:
As part of the cobas® pure integrated solution, the cobas® c 303 standardizes operations and results with other cobas solutions (such as cobas® pro), simplifying staff training and optimizing patient management. It also provides a broad test menu with over 230 clinically valuable assays.
