Efficiency, simplicity and security for the modern laboratory

The cobas p 312 pre-analytical system offers benefits in a number of areas:

Compact – small footprint, lots of power

cobas p 312 pre-analytical system is a standalone solution offering maximum efficiency at a minimal space requirement = 1m2

  • High throughput of 450 samples/hour
  • Sample registration
  • Decapping
  • Sorting
  • Archiving

Flexible – convenient single point of entry

Through convenient sample loading, the cobas p 312 is the ideal single point of entry for reduced complexity. There is no need to pre-sort sample tubes prior to loading them in the input area.

cobas p 312 can simultaneously process:

  • different tube types
  • different tube heighs
  • different tube diameters


Safe – Validated for cross-contamination compliance

The cobas p 312 is validated for both serology and molecular diagnostics testing.

Effortless – Traceability and control of lab processes

Standardization of laboratory process is key for fast and consistent results, while reducing errors.

Pre-analytics has become a critical function of the busy laboratory for this reason, and Roche is leading the way in innovative solutions that can make a significant difference to laboratory workflows, processes and practices. At the forefront of this is the cobas p 312, a machine that has transformed the capabilities of one very large laboratory in this vibrant city.
