Assays Onboard59 assays, including 3 ISE (Na, K, Cl)
Sample Handling
Sample Tubes5 mL, 7 mL, and 10 mL tubes; 1 mL and 2 mL sample cups; user-defined containers
Sample Tray84 sample positions; positive sample identification
Validated Sample TypesSerum, plasma, urine, whole blood, and CSF, assay-dependent
Sample Integrity ControlQualitative check for hemolysis, lipemia, and icterus; clot detection, flagging, and management; short-sample
detection, flagging, and management
STAT Handling84 positions, not dedicated; STAT samples are processed with priority
Auto-repeat TestingAutomatic repeat testing from the retained prediluted sample or original sample
Sample DilutionAutomatic dilution up to 1:5625 from retained prediluted sample or original sample
Auto-reflex TestingAutomatic ability to perform additional tests based on results of first test or test combination
Primary Sample ProbeLiquid-level sensing, crash protection, clot/clog detection, liquid-surface verification
Sample Carryover PreventionAutomated wash; additional automated sample probe washes programmable for greater prevention
Sample ThroughputUp to 200 tubes per hour with ISE use; faster without ISE use

Micro-volume Technology  
Automatic Sample PredilutionSamples typically diluted 1:5 (30 μL sample + 120 μL saline generates up to 15 tests results);
retained for auto-repeat, auto-reflex, or auto-dilution until results are available
Predilution Tray120 dilution cuvettes
Sample Volume per Test2–30 μL of prediluted sample, equating to 0.4–6.0 μL of original sample per test (varies by assay)
Average Reagent Volume80–120 μL per test, assay-dependent
