  • Confidence, with simultaneous multiwavelength PSI technology designed to minimize the effects of preanalytical errors, leading to more accurate patient results
  • Lab-to-lab consistency for multisite patient monitoring, with sample result traceability for in-depth audit capabilities and sophisticated cap-piercing technology
  • High-capacity performance with extended walkaway time to free up valuable tech time and increase operating efficiency
  • Operational efficiency in a compact, cost-efficient footprint, with a wide spectrum of assay parameters—enabled by four measurement principles—all on one analyzer
  • Uninterrupted workflow, with flexible sampling capabilities, seamless testing for improved throughput and maximum productivity, and minimal downtime and maintenance

The Sysmex CS-2500 System offers mid-volume and multisite labs smartly designed technologies that improve sample management, increase efficiency, and streamline lab workflow. Advance with confidence by leveraging:

sysmex 2500
    • Simultaneous multiwavelength PSI technology with primary-tube sample-volume check and double aspiration clog detection identifies and automatically manages potentially problematic test samples prior to analysis, minimizing repeat testing and manual reviews.
    • Intuitive system interface helps streamline lab operations with onboard help, configurable maintenance, automated quality control checks at user-defined intervals, and real-time monitoring of reagents and consumables.
    • Identical cutoff values and results that correlate with the entire Siemens family of hemostasis systems allow standardized monitoring of patients from lab to lab.
    • Instruments, PSI technology, assays, and results are seamlessly integrated across multiple labs.
    • Standardized software, reagents, controls, and calibrators improve convenience, offer cost savings, and reduce waste for more efficient labor utilization.
    • A standardized single point of contact for all your hemostasis needs provides convenient ordering and service coordination.
    • Fully loaded reagent capacity of up to 40 reagents and 5 additional buffer or diluent positions support up to 3000 tests* onboard.
    • Flexible vial-type management enables use of multiple vials for variety of tests simultaneously.
    • System throughput is approximately 180 simultaneous PT/APTT tests/hour.*
    • Anti-evaporation caps and refrigerated reagent chamber at approximately 10⁰C maximize onboard reagent stability.
    • Vial-sampling angle provides greater usable reagent volume and number of tests per vial.
    • Smart calibration capability enables use of multiple lots of same reagents onboard.

    Reaction-kinetics analysis and four measurement principles (clotting, chromogenic, immunoturbidimetric, and aggregation**) are combined on one analyzer.
    The system includes data storage capacity of approximately 10,000 samples, with up to 60 results per sample.
    24-inch wide-screen LCD display with touch operation and Microsoft Windows 7-based software provide easy operation.
    Sample result traceability allows in-depth audit capabilities.
    Wide spectrum of analysis methods such as automated reanalysis and reflex testing are packaged in a compact footprint.

    • Sophisticated cap-piercing technology supports use of various capped and/or uncapped sample tubes and cups for dependable throughput under all conditions.
    • The system supports simultaneous processing of normal and micro-mode samples.
    • Daily maintenance can be performed in less than 5 minutes* and recorded at the touch of a button.
    • Access to the reagent table while the instrument is running enables continuous loading of reagents, consumables, and samples.
    • Evaporation cap, SLD mini cup, and vial-sampling angle significantly reduce waste.
