cobas® 4800 system

Innovation made simple


The cobas® 4800 system offers state-of-the-art test menu, fully automated sample preparation, real-time PCR amplification/detection and easy-to-use software for multiple sample types (the detection of Chlamydia). trachomatis (CT), Neisseria. gonorrhoeae (NG), Human Papillomavirus (HPV) and an expanding menu of assays.

It consists of the cobas x 480 instrument for the nucleic acid extraction sample preparation and PCR pipetting and the cobas z 480 real-time PCR analyzer.


The cobas z 480 analyzer is also available as single system and can be used for parameters in the oncology field like BRAF, KRAS and EGFR.

cobas x 480 instrument

  • Fully automated sample preparation from primary vials
  • Ready-to-use, load-and-go reagents
  • No thawing or mixing required
  • Less than 20-minute set-up for full run of 94 samples

cobas z 480 analyzer

  • Real-time PCR with digital data capture provides accurate qualitative results with no grey zone
  • Eliminates the need for equivocal sample retesting
  • Advanced results algorithm eliminates the need for manual curve analysis
Dependable performance, dependable results.

For reliable real-time PCR for medium to high throughput labs, the cobas® 4800 system was engineered to inspire confidence. It uses the latest generation of LightCycler® Technology to deliver reproducible results and represents a new standard in innovation.

CO-RE tip technology

Improves sealing by securely locking pipette tips in place with an O-ring that expands smoothly to fit a specially designed groove. This O-ring gently decompresses during tip release to avoid motions that can create sample/reagent aerosols that lead to cross-contamination.

A proprietary Total Aspirate and Dispense Monitoring (TADM) system

Ensures valid results by monitoring the pressure within tips to detect low volumes and clogs; pressure responses that fall outside the expected range are reported as errors.

Five optical channels

To detect multiple targets from one reaction tube.

Designed for bi-directional LIS communication

To simplify test ordering while supporting integrity of results (no manual data entry required).

Includes remote diagnostics support

Through a secure web connection, our Service and Technical Support team can streamline troubleshooting and minimize downtime.


1) Simplifies workflow efficiency.

Streamlined design helps save time and resources because:

It requires less hands-on time than most comparable systems and needs minimal daily maintenance. The cobas® 4800 system enables and frees staff to spend more time on other critical tasks.

It accommodates multiple sample types and flexible batch sizes and provides an easy-to-use software interface that can make operation simple even for lab techs with no molecular diagnostics experience.

Roche assays for the cobas® 4800 system help deliver consistently reliable results because:

  • The proprietary AmpErase enzyme destroys virtually all previously generated amplicon to reduce cross-contamination concerns that can lead to false-positive results.
  • Automatic internal controls minimize the potential for false-negative results.

Each test is automatically analyzed with a unique kinetic algorithm so results are clearly positive, negative or invalid.

The cobas® 4800 system delivers fast results to help meet demanding turnaround times:

  • Requires < 40 minutes of hands-on time (96 sample run).
  • Reagents are ready to go, no preparation required.

The cobas® 4800 system features primary tube loading to eliminate manual sample transfer steps.

The cobas® 4800 system enables flexible ordering for an expanding, diverse menu of individual, combination or laboratory-developed tests.


2) Innovation that gets down to business.
