Class I
Mindray BS-240 Chemistry Analyzer
Mindray · Model BS-240
Fully automated biochemistry analyzer for small-to-medium labs with 240 tests/hour throughput.
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
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Probe clogging (sample/reagent)
MediumSymptoms: Short sample / carryover flags
Root cause: Clotted samples or dried reagent crust
Halogen lamp degradation
MediumSymptoms: Rising absorbance QC drift, photometer checks fail
Root cause: Lamp output decline over ~2000 hours
Wash station peristaltic tube fatigue
LowSymptoms: Carryover increase, bubbles in cuvettes
Root cause: Tubing loses elasticity

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 structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: QC fails only on low-concentration analytes
- Check carryover protocol, running high then low sample pair.
- Perform probe outer-wash function; increase rinse time.
- Replace peristaltic tubing if older than 6 months.
- Recalibrate affected assays and rerun QC in duplicate.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
The gas spring on the front and rear protective cover may fail. There is a low risk of injury to the user resulting from failure of the gas spring. Injury may include impact to the arms, hands or fingers.
- RECALL
An issue has been identified with the BS-200 where clinical chemistry results may be inaccurate.
