Beckman Coulter UniCel DxC 860i
Beckman Coulter · Model UniCel DxC 860i
System throughput of up to 1440 chemistry and 200 immunoassay tests per hour* ClozCap™ closed-tube sampling and aliquoting technology On-the-fly loading of chemistry and immunoassay reagents and consumables while system is running Hands-free integrated aliquot preparation Streamline parallel sample processing Single point of sample entry Combined onboard capacity of 120 different tests from a menu of more than 150 assays†.
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.
QC / calibration failure on an assay
HighSymptoms: Controls out of range, calibration fails, flagged results on one or more assays.
Root cause: Reagent pack issue, a probe / dispense fault, incubation-temperature drift, or a detector / optics fault.
Sample / reagent probe or pipettor fault
MediumSymptoms: Short aspiration, no dispense, clot / level-sense errors, carryover.
Root cause: Clogged or bent probe, a syringe / pump fault, or a level-sense fault.
Wash / aspiration station fault
MediumSymptoms: High background / noise, poor precision, elevated blanks.
Root cause: Blocked wash-station nozzles or a wash-pump / vacuum fault.
Incubator temperature fault
MediumSymptoms: Assay drift or bias, incubation-temperature alarm.
Root cause: Incubator heater or temperature-sensor fault.
Detector / luminometer / photometer fault
MediumSymptoms: Low signal, high CV, detector-error message.
Root cause: PMT / detector ageing or an optics fault.

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: QC / calibration failure on an assay
- Run fresh controls at all levels and recalibrate the affected assay.
- Confirm the reagent pack is in date, mixed and correctly loaded.
- Clean the sample / reagent probes and the wash stations.
- Check the incubator temperature against a reference.
- Escalate a detector / luminometer / photometer fault to the OEM.
Symptom: Sample / reagent probe or pipettor fault
- Inspect the probe for a bend or clog and clear it.
- Run the fluidics prime.
- Check the syringe / dispense pump and tubing for leaks or air.
- Verify level sensing and probe position.
- Replace the probe or syringe as found and re-run QC.
Symptom: High background / poor precision / elevated blanks
- Clean or unblock the wash-station nozzles.
- Check the wash pump and vacuum.
- Confirm the substrate / trigger reagents are fresh.
- Run a precision check.
- Escalate an optics / detector fault.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
The recall was initiated because Beckman Coulter has confirmed that the current sample syringe pump drive assemblies installed on DxC Integrated ystem with UniCel Closted Tube Aliquotter (UCTA) serial numbers between 547 and 574 may cause a hardware motion error (ID0x08000501).
- RECALL
Beckman Coulter is initiating a recall on their UniCel DxC Clinical Systems (880i, 860i,680i and 660i Systems with serial number <2760 that have software version 4.9.01 installed and have the VME Motorola ICS board) because they may exhibit issues with stat sample rack loading, causing a possible delay in results.
- RECALL
The recall was initiated after Beckman Coulter confirmed reports of inaccurate Access Intrinsic Factor Ab test results displayed on, or printed from, the UniCel Dxl portion of an integrated workstation listed above. The problem is limited to numerical Intrinsic Factor Ab results produced on integrated systems running UniCel Dxl system software version 4.0, 4.1, or 4.2. The DxC portion of your inte
