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
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.
Will not power on or unexpected shutdown
HighSymptoms: The laboratory & diagnostics is dead, reboots, or shuts down mid-use.
Root cause: Mains lead / fuse, an aged battery, or a power-supply board fault.
Battery will not hold charge
MediumSymptoms: Short run time on battery; low-battery alarm soon after a full charge.
Root cause: Aged rechargeable battery pack or a charger fault.
Display / control-panel fault
MediumSymptoms: Blank, dim or distorted display; unresponsive keys or touchscreen.
Root cause: Display, backlight, or control-board fault.
Fails self-test or calibration
MediumSymptoms: Power-on self-test or the scheduled performance check fails or is out of tolerance.
Root cause: Sensor drift or an internal board fault; recalibration or repair needed.

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: Will not power on
- Confirm the outlet, mains lead and fuse.
- Try on battery, then on mains only, to isolate the supply.
- Look for a power indicator or POST code.
- Replace the fuse / battery / power supply as isolated.
- Run the self-test after any repair.
Symptom: Fails self-test or calibration
- Note the exact failure message / code.
- Power-cycle and repeat the self-test.
- Verify against a reference / simulator where one applies.
- Recalibrate per the service manual.
- Refer the affected board for service if it will not hold calibration.

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
