Beckman Coulter ACL 2000
Beckman Coulter · Model ACL 2000
A micro centrifugal analyzer with added capabilities such as automatic calibration The ACL 2000 is able to carry out system precision quality assurance program as well. The coagulation analyzer consists of a video display unit which continually shows the status of the equipment. It also gives necessary instructions on how to proceed.
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 / flow-cell blockage or partial obstruction
HighSymptoms: Flagged or implausible CBC counts, voteouts, clog alarms, poor precision.
Root cause: Debris or a clot partially blocking a counting aperture or the flow cell.
Sample probe / piercer / valve wear
MediumSymptoms: Short samples, aspiration errors, cap-piercing failures, carryover.
Root cause: Worn or bent sample probe / closed-vial piercer, or a worn shear / segment valve.
Reagent / lyse delivery fault
MediumSymptoms: WBC, HGB or diff results shifted, high background, reagent alarms.
Root cause: Reagent depleted or wrong lot, or a pinch-valve / tubing fault.
Optics / laser fault (diff)
MediumSymptoms: Diff scattergrams abnormal, missing populations, flow-cell or laser alarm.
Root cause: Contaminated or aged flow cell, or the laser / optics.
Vacuum / pressure out of range
MediumSymptoms: Multiple parameter errors, priming failures.
Root cause: Pump or regulator drift.

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 or flagged counts
- Run the instrument's aperture / flow-cell clear and flush cycles.
- Run a background count and confirm it is within limits.
- Run controls at all levels.
- Clean or replace the aperture bath / flow cell if clogs recur.
- Confirm precision on a replicate sample before releasing results.
Symptom: Short samples or aspiration errors
- Inspect the sample probe / piercer for wear or a bend.
- Check the shear / segment valve and tubing for leaks or wear.
- Verify vacuum and pressure against the service spec.
- Replace the probe / piercer, valve or tubing as found.
- Re-run controls.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
The recall was initiated because Beckman Coulter has confirmed that the listed lot numbers of Active Control ELISA reagent will result in falsely high values for patient samples due to a shift in the calibration of the assigned standard values. Beckman Coulter recommends that patient results, generated with the affected lots, be evaluated in the context of other diagnostic tests and the clinica
- RECALL
Version v6.4.109f, any result designated as 'calculated chemistry' at DL2000 may upload to the LIS with an incorrect or blank sample ID.
- RECALL
Software defect. The type of results affected were replicate type results for a single sample transmitted within the same data stream.
- RECALL
Software anomaly allows results to be archived prior to validation or to be uploaded to the lab information system.
