Beckman Coulter UniCel DxH
Beckman Coulter · Model UniCel DxH
• First-pass accuracy, efficiency and reduced review rates, driven by Beckman Coulter's Automated Intelligent Morphology (AIM) flow cytometric technology • Multidimensional high-definition cellular analysis enhances visual cellular investigation of abnormal specimens • Scalable built-in automation solution, capable of meeting your lab's increasing sample testing requirements • Bi-directional sample transport system which automatically distributes samples between the analyzers, preventing any potential for delay in sample testing and the reporting of results • Improve workflow and reduce TAT with auto rerun and reflex testing, driven by user-defined decision rules • Add critical STAT samples or body fluids without the need to interrupt routine sample testing • User-defined decision rules also drive automatic slide preparation and staining, without the need for manual intervention
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.
Sample probe / pipette clog
MediumSymptoms: Aspiration error, short sample, carryover.
Root cause: Clot/crystal obstruction.
Reagent / wash flow fault
MediumSymptoms: Clogs, high blank, QC fail.
Root cause: Pump tube wear, air in line.
Temperature control fault
MediumSymptoms: Incubator out of range.
Root cause: Failed heater/fan or sensor.
Optics / lamp degradation
LowSymptoms: Low signal, wavelength drift.
Root cause: Lamp/LED or monochromator aging.

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: Sample probe / pipette clog
- Confirm the presentation - typically aspiration error, short sample, carryover - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: clot/crystal obstruction.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the sample aspiration probe per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
Symptom: Reagent / wash flow fault
- Confirm the presentation - typically clogs, high blank, QC fail - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: pump tube wear, air in line.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the peristaltic pump tubing per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Due to specific lots of diluents contributing to elevated platelet Daily Checks background counts cycle with use with analyzers.
- RECALL
Hematology analyzers configured with HGB photometers may result in erroneously high hemoglobin (HGB) results on samples with elevated white blood cell (WBC) counts.
- RECALL
When the UniCel DxH Slidemaker Stainer and UniCel DxH Slidemaker Stainer II dispense probe is slightly bent, there is a potential for cell carryover from the previous sample, and erroneous results could be reported from the slide review. Erroneous results may be reported from the laboratory which may trigger unnecessary or inappropriate patient treatment.
- RECALL
The firm has identified that a fitting in some Slidemaker Stainer units may not completely seal after installation.
- RECALL
Beckman Coulter is recalling the UniCel DxH Slidemaker Stainer Coulter Cellular Analysis System to reduce the potential for flammable liquids coming into contact with electrical components in the Stainer module possibly causing a fire.
- RECALL
The recall was initiated because Beckman Coulter has confirmed that the DxH Slidemaker Stainer Floor Stand shipped with Slidemaker Stainer instruments were missing vinyl caps, exposing sharpt edges on the DxH Slidemaker Stainer Reagent Cabinet (Floor Stand) drawer slides. The sharp edges on the drawer slides may expose operators to physical injury when replacing reagents and waste containers whic
