5 Reasons Compact Labs Choose the Roche Cobas Pure c303 for Chemistry and ISE Testing
Not every laboratory needs a floor-filling chemistry line. Satellite labs, mid-sized hospitals, and clinics running a few hundred samples a day still need a full chemistry menu plus electrolytes, and too often that means a photometric analyzer on one bench and a separate electrolyte instrument on another. Every extra instrument adds sample handling, bench space, and one more system to maintain.
Roche Diagnostics' cobas pure integrated solutions was designed for exactly this situation, and its chemistry unit, the Roche Cobas Pure c303, puts photometric and ion-selective electrode (ISE) testing in a single analyzer.
Here are 5 reasons compact laboratories choose the Roche Cobas Pure c303.
1. Photometric and Electrolyte Testing in One Unit
The c303 combines a photometric measuring unit with an integrated ISE unit that measures sodium, potassium, and chloride. Both share the same sample pipetter, so a single sample can run chemistry and electrolytes without being moved to a second instrument. That removes a handoff, a bench, and a separate daily routine from the lab.
2. Up to 750 Tests per Hour in Mixed Mode
In mixed mode, combining photometric and ISE tests, the c303 delivers up to 750 tests per hour. That is ample capacity for a lab running a few hundred samples a day, and it keeps turnaround time (TAT) predictable during the morning rush without the cost and footprint of a high-volume system.
3. A Broad Menu in a Compact Floor Model
Diamond's refurbished c303 carries a tested menu of 81 assays, covering routine panels such as the basic metabolic panel (BMP), comprehensive metabolic panel (CMP), and liver function tests. Roche's published menu also spans specific proteins, enzymes, drugs of abuse, and therapeutic drug monitoring. The analyzer runs serum, plasma, and urine samples and needs as little as 1 μL of sample.
4. Standardized with Roche's Larger cobas Platforms
Roche designed cobas pure to use the same reagents as its larger cobas pro platform, and a published multi-site evaluation notes that results should be comparable between the two regardless of workload. For laboratory networks, that means a small site and a central lab can work from the same reagent generation and expect consistent results. Roche also describes automatic calibration of new reagent lots for most clinical chemistry tests (cobas AutoCal), which cuts down on routine hands-on work.
5. Cost-Effective Capacity Through Refurbishment
A compact, modern platform like the c303 does not have to come at new-system pricing. A certified refurbished unit gives small laboratories photometric and ISE capability at a significantly lower acquisition cost, and every unit sold by Diamond Diagnostics is eligible for field service coverage.
Equip Your Lab with a Compact Chemistry and ISE Platform
At Diamond Diagnostics, we help laboratories right-size their chemistry capacity so they are not paying for throughput they will never use. If you are comparing compact Roche options, our guide to the Roche Cobas c311 covers another popular choice for mid-sized labs.
Every Roche Cobas Pure c303 we supply undergoes our complete Down-To-Frame® refurbishment protocol, including full disassembly, component-level restoration, and rigorous multi-level quality control validation, so your lab gets day-one analytical confidence.
