Simplicity meets Excellence

Today more than ever, the importance of accurate and timely diagnostics is clearly understood. The journey from blood collection to the final test result, however, requires the highest level of dedication, expertise and diligence of the laboratory staff.

To support you in this, Roche has developed innovative integrated solutions renowned for quality and excellence.

cobas® pure integrated solutions is the newest member of the cobas® family of systems which is designed to deliver excellence, while at the same time simplifying your daily work. cobas® pure combines clinical chemistry, immunochemistry and ISE testing on a footprint of ~21 square feet, giving access to our broad menu of more than 186 parameters – including many unique high medical value assays, to labs who have to deal with limited space.

To simplify daily operation, cobas® pure comes with new features that minimize the hands on work for the operators, thus saving precious time.

To ensure simple and effective work for network organizations, cobas® pure provides fully standardized results and operation to cobas® pro integrated solutions – Roche’s latest analyzer designed for larger labs.

Because simplifying any step of the journey can help deliver fast and accurate diagnosis.

Bring more confidence to your team with reliable and safe solutions

Unplanned downtime and lack of confidence in results are some of the most stressful things that can happen in the lab. The staff must shift their attention to time-consuming, manual workarounds or sample reruns which can cause frustration and impact staff morale and motivation.

Additionally, they pose risks to the quality of results and the lab’s reputation. cobas® pure integrated solutions is designed to deliver distinctive reliability through sound system architecture and confidence in the results through various safety features.

Safety of results1


Disposable AssayTips/AssayCups

cobas pure immunochemistry analytical unit utilizes single-use disposable Assay Tips and AssayCups to virtually eliminate the risk of sample carry over.


Carryover evasion program

The sample probes on the cobas pure clinical chemistry analytical unit are rinsed inside and outside with deionized water each time after dispensing a sample. Additionally, for applications that are sensitive to sample carryover, special wash can be programmed for an extra wash of reagent probes, sample probes and reaction cells with basic and acidic wash solutions.


Ultrasonic Mixing

The cobas pure clinical chemistry analytical unit features ultrasonic mixing for non-contact mixing of sample and reagent to eliminate the risk of carryover during this event.



cobas® pure integrated solutions is designed to deliver the reliability that Roche is known for. With more than 75,000 analytical units globally, the cobas family of solutions demonstrates a distinctive uptime* of more than 99 %.7 Having a reliable analyzer means less interruption of services and less time spent on troubleshooting, thus higher productivity with more predictable turnaround times.


* Uptime: Percentage of the time when system is up and running vs. the time the system is not running due to unplanned incidents. Calculation:
(365 days/Mean time between repair visit) × (Mean time for repair visit + Travel Time)7

Lab staff looking at analyzer

Enable your team to work more efficiently with standardized solutions

Lab standardization enables you to do more work on fewer instruments, through consolidation of workflow, systems and reagents. Standardization also provides efficient and compatible solutions for network cooperation.

Essential benefits of standardization


Improved speed and accuracy of results

Same reagents and detection technology mean standardized reference ranges which improve the speed and accuracy of results.


Simplified training and staff allocation

Common user interfaces between our cobas® systems simplify training and allow for flexible staff allocation as healthcare centers are consolidating into larger integrated health networks.


Optimized patient management

Consistent results over time and across different locations enable optimized patient management.

Empower your physicians to take action faster


Standards are being raised across health systems, as patient and physician satisfaction along with fast clinical decision making are becoming more prominent quality metrics. Choosing an analyzer that supports short and predictable turnaround times at peak times is a key to meet these standards.

Get answers fast with short and predictable turnaround times.


cobas® pure integrated solutions is designed to support fast and predictable turnaround times across all assays.

93 % of Roche immunoassays have reaction time of 18 minutes or less, with STAT assays having just 9 min reaction time.2

To offer full transparency, cobas® pure integrated solutions allows the operator to see the time to result per sample and per test as well as the time to last result on all ordered tests.

Benefit from reduced system preparation and hands-on time

Free up staff time with reduced hands-on maintenance efforts


With cobas® pure integrated solutions, every effort has been made to reduce hands-on maintenance tasks to a minimum. The new and smart concept of self-operating maintenance executes maintenance tasks automatically in the background and reduces the manual burden of daily maintenance to 5 min.1

Save time and costs with cobas® AutoCal


The clinical chemistry module of cobas® pure integrated solutions comes with a significantly simplified calibration concept - automated calibration. With cobas® AutoCal, new reagent lots for the majority of clinical chemistry tests are calibrated automatically, without the need for manual calibration. This can lead to 56 % less calibration events, saving up to 105 hours of hands-on time yearly.*3
