cobas® 8100 automated workflow series

3-D intelligence in lab automation


  • cobas® 8100 fully automates the laboratory process from sample entry to archive
  • Easily adapts to the growing laboratory’s needs and preferred workflow
  • Intelligent tube transport pro­vides a short predictable time to results, including prioritization for emergency samples
  • Covers the needs of a high-throughput laboratories achieving 1,100 samples/hour
  • Increased traceability throughout sample processing
  • Designed with options for connectivity to a range of instruments and post-analytics

cobas® 8100 automated workflow series




The cobas® 8100 is made up of three stations:

  • Output station
  • Input station
  • Aliquot station

Each station can be configured according to the number of samples and individual laboratory needs in order to optimize the required workflow now. In the future, it can easily grow as needed.

3-D intelligence in lab automation

The cobas® 8100 automated workflow series offers benefits in a number of areas:

Quality comes first

At an early pre-analytical stage, Roche automation solutions perform an extensive inspection of samples for maximum workflow efficiency.

Quality check via optical camera

Quality check via optical camera

  • Sample quality check via a high resolution optical camera which enables to detect among normal, hemolytic, lipemic and icteric samples. Samples with inadequate quality for analytical processing will not continue their path.
  • Tube type identification allows you to cross check the tube type and its cap color and barcode information to detect possible errors.
  • Laser Liquid Level Detection allow you to detect samples volume in ml through 3 barcode labels. Samples that don’t have an open window are not missed (prioritized process of samples/aliquots based on available volume).

This early decision stops inadequate samples for analytical processing to continue their path, reducing workload and no reagents are wasted. Overall, if a sample has an error or issue, you can act in an early stage ensuring the shortest time to results and consistency.

Workflow your way

Personalized workflows enable you to choose from primary, aliquot or mixed workflow.

  • Primary sample workflow – if the focus is on cost efficiency
  • Aliquot workflow – if the focus is on sample integrity and parallel testing 
  • Mixed workflow – to optimize the benefits of both

Short and predictable time to results

  • 3D intelligent tube transport improves patient care by offering reliable results within predictably short turnaround times, even during peak workflows 
  • Multi-level and bidirectional tube transport: empty tube holders and holders with tubes run separately to avoid traffic jams 
  • Tubes always have a clear destination and do not circle the track, guaranteeing first-in first-out sample processing 
  • Tubes can bypass modules if processing is not required 
  • Prioritized STAT workflow

Flexible tube storage 

A solution with cobas® 8100 offers 3 storage concepts, ensuring fast access as soon as a tube is needed. 

  • Short-term storage for an immediate re-run 
  • Mid-term storage in the Add-on Buffer Module – for optimized add-on request processing within the same day 
  • Long-term storage

Maximum consolidation

  • Broad reagent portfolio to consolidate 98% or more of routine serum work area load
  • Designed with options for connectivity to immuno & clinical chemistry, hematology, coagulation, selective third-party analyzers and archiving
  • cobas® 8100 fully automates the laboratory process from sample entry to archive
  • Integrated post-analytic solutions with add-on buffer module for add-on requests within one day
