Swelab AC-Series
Swelab · Model AC-Series
All parameters and histograms (RBC, WBC, PLT) showed on display and print-out. Memory of 800 control results, and 600 samples including histograms. Levey-Jennings plots and X-bar calculations. No start-up time and automatic stand-by position. Built in dilutor–only one manual step has to be performed. Case Book with over 80 examples of hematological diseases, physological changes and artefacts AutoCounter (AC), compared with the microscopic blood smears. Reagent level detectors. Printer output and serial output as standard.
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.
Aperture blockage / clog
HighSymptoms: Flagged or implausible CBC counts, clog alarm, poor precision.
Root cause: Debris or a clot partially blocking the counting aperture.
Reagent / diluent delivery fault
MediumSymptoms: WBC / HGB results shifted, high background, reagent-empty or pressure alarms.
Root cause: Reagent pack depleted or expired, or a valve / tubing fault.
Sample probe / pipettor fault
MediumSymptoms: Short samples, no aspiration, probe-position errors.
Root cause: Worn or bent sample probe, or a clot in the sample.
HGB photometer drift
MediumSymptoms: Haemoglobin results biased, blank absorbance off.
Root cause: Photometer lamp aging or a dirty flow cell.

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: Clog alarm / flagged counts
- Run the aperture-clear / flush cycle.
- Run a background count and confirm it is within limits.
- Run controls at all levels.
- Clean or replace the aperture assembly if clogs recur.
- Confirm precision on a replicate sample.
Symptom: Short samples / shifted results
- Inspect the sample probe for a bend or blockage.
- Check the tubing and valves for leaks.
- Confirm reagents are in date and correctly loaded.
- Replace the probe or tubing as found.
- Re-run controls.
