With random access sampling and no common processing components for CH and IM analysis, the Atellica CI 1900 can run up to 1120 tests per hour.*

Operational efficiency

Up to 1120 tests can be run per hour* using independent integration and random-access sampling, which maximizes throughput.

  • Maintenance: <5 minutes hands-on daily maintenance
  • STAT Testing: STAT sample processing within 60 seconds
  • Consumables: load/unload reagents and system consumables on the fly, and during sample processing
  • Standardized to Atellica Solution: providing continuity across the network and sustainability efforts across Siemens Healthineers
