cobas 6800 system

8 hours workaway time*

Transform "walk-away" time into "work-away" time. Minimal and intuitive interactions reduce the potential for human error and free-up technicians for other tasks. 

  • Pre-Calibrated, ready-to-use reagents do not require thawing, mixing, pouring or calibrations. Load and go. 
  • Automated onboard storage and refrigeration system enable ready access and maintain inventory of consumables and reagents 

*May vary based on workflow demands.

cobas® 6800 System

Contamination prevention

Built in features to ensure the highest quality and integrity of patient results with no daily maintenance

  • Airlock doors with HEPA filtration
  • Pipette tips with filter technology
  • Dedicated pipette tips for each sample transfer and for transfer of extracted nucleic acid
  • Automatic heat-sealing of cobas omni Amplification Plate
  • Amperase included in every assay
  • Stainless steel 8-fold needle popetting transfers assay-specific reagents, controls and other bulk reagents required for sample preparaton and amplification; washed after each use
  • No use of bleach on the systems

Molecular testing - at any volume - in three easy steps

run the tests you want, when you want


no reagent preparation, no manual pipetting, no sorting or batching or setting up subsequent runs - 

the cobas 6800 System does it all for you


With a broad on-demand assay menu, the cobas 6800 System allows you to run the tests you want, when you want. 
Further flexibility is possible with the cobas omni Utility Channel, a dedicated open channel for both IDV assays and high-volume labortory developed tests (LDTs). The cobas omni Utliity Channel creates an opportunity to broaden your menu and automated more testing on the cobas 6800 System.
