Reichert Technologies UNISTAT Bilirubinometer
Reichert Technologies · Model UNISTAT Bilirubinometer
Measures total bilirubin levels in under 5 seconds. Most trusted and reliable stat analysis of serum bilirubin available. Measures undiluted serum, eliminating errors from time-consuming dilution or chemical reactions. Easy to calibrate using included optical standards. Correlates between 96-99% with HPLC gold standard for measuring bilirubin.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Inaccurate bilirubin readings / QC failure
HighSymptoms: Result disagrees with a reference / control, drift over time.
Root cause: Optics contamination, lamp aging, a dirty or scratched cuvette, or calibration drift.
Lamp / light-source failure
MediumSymptoms: Low signal, will not read, lamp warning.
Root cause: Lamp at end of life.
Sample-handling / cuvette fault
MediumSymptoms: Bubble or short-sample errors, inconsistent readings.
Root cause: Air bubble in the micro-sample, or a worn / dirty cuvette.
Display / keypad fault
LowSymptoms: Unresponsive keypad, dim display.
Root cause: Aged display or keypad.
