Beckman Coulter AU2700
Beckman Coulter · Model AU2700
Standardization - Only Beckman Coulter standardizes chemistry testing from 400 to 6,600 tests per hour for low to very high volume laboratories. This translates to higher productivity, increased efficiency and greater cost savings for your lab. Fast and Reliable Turnaround Times - Up to 1600 photometric tests per hour and up to 2133 tests per hour with electrolytes > Immediate STAT interrupt with HCFA basic metabolic eight test panel results available within five minutes. 300-sample rack loading for peak workloads. 22-sample carousel for STAT. Direct tube sampling for 3.0, 5.0, 7.0, 10.0 mL primary tubes and pediatric cups. Mixed bar code capability. Automated reflex and repeat testing. Automated pre-dilution for urine and other specimens. Easy connectivity for automation. Reagents are liquid and ready-to-use. Barcoded cartridges provides on-board management (random placement, on-board stability and calibration tracking). All 48 R1 and 48 R2 reagent positions are open for third-party reagent use. Auto-calibration and auto-quality control. Automatic changeover from empty to fresh bottle. Multiple sized reagent cartridges hold from 100 to 6000+ tests to meet the needs of any size laboratory. Minimal reaction volume of 120 µL reduces reagent consumption. Reagent inventory tracking function predicts daily workloads. Choice of QC trending: Westgard multi-rule procedure, Twin plots, Levey-Jennings daily and day-to-day plots. Search function to retrieve data by individual sample and type of test (up to 60,000 patient files). User-definable flags for abnormal results. Liquid level capacity detection to ensure accurate pipetting for reagents and specimens. Clot detection and crash prevention for probes. Exclusive spot photometric technology for precision optics.
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.
Assay / QC failure across a channel or the whole system
HighSymptoms: Controls out of range, calibration fails, flagged results, drift over a shift.
Root cause: Reagent or cuvette issue, lamp ageing, a probe / mixer / wash-station fault, or ISE-module problems.
Sample / reagent probe clog or crash
MediumSymptoms: Short aspiration, no dispense, clot detection, probe-position error.
Root cause: Clogged or bent probe, or a clot in the sample.
Cuvette / reaction-rotor fault
MediumSymptoms: High cuvette blanks, non-uniform results by position, rotor-drive error.
Root cause: Worn / scratched cuvettes or a wash fault, or a rotor-drive fault.
ISE module fault (Na / K / Cl)
MediumSymptoms: Electrolyte results biased or noisy, ISE calibration fails.
Root cause: Aged ISE electrodes / reference, or a pinch-valve / tubing fault.
Water / vacuum / pressure system fault
MediumSymptoms: Multiple station alarms, priming failures, poor wash.
Root cause: Water / DI supply quality, a pump, or a vacuum / pressure regulator.

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: Assay or QC failure
- Run fresh controls at all levels.
- Confirm reagents are in date, correctly loaded and mixed.
- Run the photometer check and replace the lamp if energy is low.
- Clean the probes, mixers and wash stations.
- Recalibrate the affected assay / ISE module and re-run QC.
Symptom: Probe clog or crash
- Inspect the probe for a bend or blockage and clear it.
- Run the fluidics prime / wash cycle.
- Check for a clot in the sample.
- Verify liquid-level sensing and probe positioning.
- Replace the probe if aspiration is still short.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
The recall was initiated because Beckman Coulter has confirmed that some AU Clinical Chemistry Analyzer ISE units can experience premature ISE REF (Reference) valve failure. Premature valve failure can be detected by the presence of air bubbles in the ISE REF solution tubing on the ISE unit. If air bubbles are present, accuracy of the ISE test results may be affected.
- RECALL
Beckman Coulter is recalling AU2700/AU2700 Plus & AU5400 Clinical Chemistry Analyzers becuase it was determined that the tubing/joint connections associated with these MODs may leak concentrated detergent. Beckman Coulter has received complaints that the joint connecting the tubing appears to disintegrate over time, causing a leak.
