cobas p 512 and cobas p 612
pre-analytical systems





Standalone solutions for maximum flexibility

Empower your lab’s ability to meet changing demands with the cobas p 512 and p 612 pre-analytical systems. These standalone automation solutions enable automation of multiple sample types with flexible sort targets. Even with a compact footprint, you can still process up to 1,400 tubes per hour.


Beyond Sorting

A compact, standalone solution that offers open automation design to handle multiple tubes and racks from virtually any third-party vendor. Roche’s standalone automation portfolio is proven with over 1,200 systems installed globally. The cobas p 512 and cobas p 612 systems also reduce the chance of downstream errors by running four quality checks prior to testing:

  • Tube Type/Test Order Match
  • Laser Liquid Level Detection
  • Laser Spin Status Detection
  • Qualitative HIL Check


Multidisciplinary Automation

In addition to traditional chemistry testing, the cobas p 512 and cobas p 612 are validated for cross-contamination compliance for molecular (NAT) testing. These systems can also automate the pre-analytic process of hematology, coagulation, and urinalysis.

Deliver predictable turnaround times with uniformed workflows to ensure a higher value of care. The cobas p 512 and cobas p 612 enable you to automate the pre-analytical process of several testing disciplines, giving you to flexibility to empower your lab to thrive.

Optimized Workflows

Elevate your laboratory with an automated single point of entry with flexible sort targets that enable automation of multiple sample types. Whether your automation needs are basic, intermediate, or advanced, Roche has a standalone solution for them.
