Whether you're a standalone lab or part of a larger healthcare system, the C311 helps deliver fast and accurate results without needing a large footprint.

In this article, you'll learn why the Roche C311 is an ideal chemistry solution for mid-sized labs, including its key features, benefits, and applications.

What Is the Roche C311 Analyzer?

The Cobas C311 is a bench-top clinical chemistry analyzer that performs photometric and ion-selective electrode (ISE) testing. It is part of the Roche Cobas family, which includes scalable solutions for laboratories of all sizes.

The system is designed for labs needing dependable chemistry testingfast, accurate, and easy to managewithout the complexity of high-volume systems.

Key Features of the C311 Chemistry Analyzer

1. Throughput for Mid-Volume Labs

The C311 processes up to 300 photometric tests per hour and 450 tests per hour with the optional ISE unit. This throughput fits the needs of mid-sized labs handling routine daily testing across multiple departments.

2. Broad Test Menu

The analyzer supports more than 100 different chemistry parameters, including:

• Basic metabolic panel (glucose, urea, creatinine)
  
  

• Liver function tests (ALT, AST, ALP, bilirubin)
  
  

• Electrolytes (sodium, potassium, chloride)
  
  

• Lipid profile (cholesterol, HDL, LDL, triglycerides)
  
  

• Enzymes, proteins, and therapeutic drug monitoring
  
  

Roche reagents are pre-packaged and barcoded, ensuring accuracy and easy setup.

3. Compact, Space-Saving Design

As a standalone bench-top unit, the C311 fits in tight lab environments without compromising performance. It's perfect for labs needing a full-featured analyzer but working with limited space.

4. Automated Sample and Reagent Handling

The system includes:

• 30 sample positions with continuous loading
  
  

• 42 reagent positions with onboard cooling
  
  

• Barcoded sample and reagent identification
  
  

• Automated dilution, rerun, and reflex testing
  
  

These features minimize hands-on work and reduce the chance of manual errors.

5. Reliable Detection Technology

Using absorbance photometry and ISE technology, the C311 delivers consistent and precise results. Its built-in controls and real-time monitoring ensure high-quality output every time.

6. Easy-to-Use Interface

The analyzer includes a modern software interface with:

• Touchscreen operation
  
  

• Guided workflows
  
  

• Real-time performance monitoring
  
  

• Onboard quality control management
  
  

This makes it easy for lab staff to run tests, even with minimal training.
