Beckman Coulter DXI 600
Beckman Coulter · Model DXI 600
Onboard capacity of 50 refrigerated reagent packs enhance flexibility - configure the system menu to match your testing requirements Large on-board reagent capacity simplifies reagent management Bar-coded, liquid, ready-to-use reagents – no reagent preparation Standardized design of reagent packs across UniCel Access immunoassay systems Excellent correlation of results across platforms A broad menu across a wide variety of disease states enables your laboratory to consolidate workstations and recapture testing currently being sent out Rapid assay kinetics improve turn-around times System supports multiple assay protocols designed so assay performance is optimized Magnetic particle separation with enhanced chemiluminescent detection delivers exceptional clinical performance Large on-board capacity of up to 60 samples at once with continuous loading capability streamlines user sample processing Sample Racks are compatible with all UniCel systems, reducing sample handling across multiple systems Sample Racks can be loaded directly from the centrifuge, reducing manual processes and improving turn around times Routine sample loading can be interrupted to load STAT samples quickly "Point-in-space" pipetting technology aligned with CLSI guidelines allows integration with laboratory automation systems System releases the primary tube after creating an aliquot allowing for more efficient processing of samples Automatically creates aliquots based on the volume of requested tests System can be configured to aspirate additional volume required for user-defined reflex or re-run test scenarios System stores aliquots for up to three hours in a refrigerated low-evaporation compartment Simplifies inventory management - utilize same type of vessel for aliquots and reactions Load reagents and all consumables ‘on-the-fly’, without using the console computer or pausing the instrument, minimizing operator intervention Easy to use Windows based software Large volume supplies maximize walkaway capability Intuitive operator interface, with touch screen capability, maximizes efficiency Auto-matched pipettors work in parallel to deliver sample and reagent into the reaction vessels – and achieves a peak throughput of 200 tests per hour
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.
