AU680 Clinical Chemistry Analyzer

Designed for flexibility in the laboratory

Meet ever-increasing pressures on time and productivity with ease. The AU680 clinical chemistry analyzer gives mid- to high-volume laboratories the flexibility to improve efficiencies and economics their way. Operate the AU680 as a standalone system or connect it to laboratory automation and IT solutions. With throughput of up to 800 photometric tests per hour (up to 1,200 with ISEs) and 63 onboard parameters, the AU680 clinical chemistry analyzer delivers field-proven reliability and efficiency to laboratories around the world.

The AU680 intuitive graphical user interface includes:

  • Sample tracking
  • Patient statistics
  • User-customized menu
  • Color alerts to highlight system operating conditions

AU-proven reliability enables greater uptime with quick and easy parts replacement

  • No tools required
  • No more than three steps, no longer than 60 seconds, for parts such as sample and reagent probes, mixers and syringes
  • Online help videos guide the operator on proper technique when performing maintenance procedures and parts replacement, which enables greater system uptime

Additionally, the AU680 chemistry analyzer provides:

  • Integration of pre-analytical automation and immunoassay is attainable with AU680 Direct Track Sampling to Power Processor and connectivity to UniCel DxI 600/800 systems
  • Command Central integrated with REMISOL Advance* enables remote monitoring of and access to instruments and automation consoles from a single workstation, optimizing laboratory management and improving decision-making
  • Cooled STAT compartment provides one-button STAT interrupt and advanced auto QC and calibration capabilities
  • High-precision microsampling provides accurate and precise results
  • Priority sample repeat/reflex reduces turnaround time for critical patients  
  • Long-lasting ISEs minimize downtime and reduce operating costs
  • Large 150-sample rack loader provides for optimal sample processing during peak workload periods
  • Whole blood sampling capability is used for HbA1c testing
