Roche Reflotron Plus
Roche · Model Reflotron Plus
Quick Results. Immediate ready for measurement standby mode. 30 micro liter whole blood, plasma or serum. Quantitative results after 2-3 minutes. Easy to use. Navigation via display. No reagents preparing, No calibration necessary. Automatic parameter detection. Economic testing. Compact bench top analyzer. Single test determination. Long stability of the reagents.
Key tips
- ·Run QC controls before trusting any repair - an analyzer that passes self-test can still report clinically wrong results.
- ·Rule out a reagent lot change before opening the instrument - it can look exactly like a hardware fault.
- ·Centrifuge rotors have a hard retirement age/cycle limit regardless of visible condition - don't eyeball it.
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.
Result questionable / QC failure
HighSymptoms: Result does not fit the clinical picture, on-board or liquid QC fails.
Root cause: Expired or heat-damaged reagent strips, a wrong-volume / clotted / haemolysed sample, or use outside the operating temperature range.
Optics / measurement-chamber fault
MediumSymptoms: Repeated optics or reflectance errors, strip not read correctly.
Root cause: Dirty or aged optics / lamp, or a contaminated measurement chamber.
Strip transport / magnetic-code fault
MediumSymptoms: Strip not transported or the magnetic code not read.
Root cause: Worn strip-transport mechanism or a magnetic-head fault.
Heater / temperature fault
LowSymptoms: Measurement-chamber temperature not at 37 C, results drift.
Root cause: Heater or temperature-sensor fault.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily QC controls run and reviewed
- ·Calibration verification per assay
- ·Routine cleaning and decontamination
- ·Scheduled reagent-path and pump-tubing maintenance
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Result questionable / QC fails
- Repeat with a new strip from a correctly stored, in-date pack and a fresh, non-haemolysed sample of the correct volume.
- Run the liquid QC (Precinorm / Precipath).
- Check the operating temperature.
- Clean the measurement chamber and optics per the manual.
- Quarantine the strip lot if QC fails; refer the analyzer if QC passes but a result still looks wrong.
Symptom: Strip not read / transported
- Confirm the strip is inserted correctly, magnetic code down.
- Clean the strip channel and magnetic head.
- Check the transport mechanism.
- Retry with a fresh strip.
- Refer for service if it still will not read.
