Automation and innovation at the touch of a button

The GEM Premier 4000 system measures pH, blood gases, electrolytes, metabolites, CO-Oximetry and more, while automating quality management through iQM, instrument maintenance with its multi-use disposable GEM PAK and information management with GEMweb Plus 500 Custom Connectivity.


  • Continuous quality assurance, everywhere
    iQM technology provides automated quality assurance, continuously, unlike traditional (auto or manual) QC offerings. With automatic detection, iQM performs continuous checks with each and every sample. Error detection time is reduced from hours to minutes and errors are automatically corrected and documented for a complete picture of quality.
  • Advanced simplicity
    Multi-use, GEM PAK offers advanced simplicity at every point-of-care. Fully self contained, the GEM PAK automates the most labor-and skill-intensive processes and is available in multiple menu and test volume configurations, GEM PAKs have a use-life of 31-days and require no refrigeration. They allow ultimate flexibility for point-of-care testing needs throughout the hospital.
  • Management and compliance simplified
    GEMweb Plus 500 Custom Connectivity is designed to simplify operator supervision and quality management with full traceability. All from a single interface, whether accessed in the lab, at the point-of-care or remotely from an analyzer, PC or tablet device, GEMweb Plus 500 provides customizable and automated functionality for complete control of analyzers and operators.

Self-contained, closed system for automated continuous assurance, regardless of operator or location.

GEM Premier 4000 with iQM GEM PAK

Closed analytical system means outside variables are eliminated and errors are known, limited and predictable through pattern recognition

Pattern recognition technology made possible by analysis of thousands of GEM PAKs in clinical use, enables detection and correction of common errors

Continuous monitoring of all analytical processes before and after every sample for ultimate assurance
