cobas® 6800 System

High throughput and maximum walk-away time

Sample supply

Samples are placed onboard the sample supply module using standard 5-position racks and supporting rack trays. Each sample is then moved automatically into the transfer module. Sample racks hold 5 primary or secondary sample tubes. Each rack tray holds 15 sample racks, for a total of 75 sample tubes per tray.

Sample transfer

The transfer module automatically moves samples into the System for barcode scanning and subsequent transfer from primary or secondary tubes onto the cobas omni processing plate.

Sample preparation

Extraction and purification of nucleic acids from input samples takes place in the processing module. The purified nucleic acids are then transferred to amplification plates, along with test-specific amplification master mixes to prepare the plates for amplification and detection in the analytical modules. The inventory manager houses all reagents, controls and consumables necessary to achieve complete automation.

Amplification and detection

The analytical module performs the automated amplification and detection of target nucleic acids using real-time PCR technology.

Own the future of molecular testing

Designed for high throughput applications such as viral load IVD monitoring, blood screening, microbiology testing and women’s health, the cobas® 6800 can run up to 384 tests in an 8-hour shift—1,536 tests in 24 hours—with only 3 user interactions per run and up to 8 hours of walk-away time.*

*May vary based on workflow demands.
