Magnetic Oscillation: An electromagnetic field moves a small metal ball back and forth in the cuvette. The Definitive Guide to the Diagnostica Stago START
Calibration Curves: For assays like Fibrinogen, you must input the calibration points manually into the system software to ensure the seconds-to-concentration conversion is accurate. The Incubation : The analyzer features 16 incubation
: A technician drops a tiny metal ball into a cuvette using a specialized ball dispenser—an essential step for the unit to function. The Incubation : The analyzer features 16 incubation wells kept at exactly 37 raised to the composed with power cap C , where samples warm up for their "moment of truth".
Monthly: Verify the temperature of the incubation blocks using a certified thermometer to ensure it remains at 37°C (+/- 0.5°C). ⚠️ Troubleshooting Common Issues Error Message / Problem Potential Cause No Clot Detected Low fibrinogen or missing ball Check cuvette for metal ball; re-run sample. Temperature Fluctuation Room draft or faulty sensor Move away from AC vents; contact technical support. Pipette Sync Error Loose connection Check the RS232 or specialized pipette cable connection. 📋 Technical Specifications Measurement Channels: 4 independent channels.
