Bio-Rad Laboratories, Inc. CFX96 Deep Well
Bio-Rad Laboratories, Inc. · Model CFX96 Deep Well
Deep wells for large volumes Detection of up to 5 targets per well, plus a channel dedicated to singleplex FRET Protocol autowriter that generates an optimal protocol for your reaction components Thermal gradient that identifies optimal annealing temperature in a single run.
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.
Thermal / block uniformity fault
HighSymptoms: Wells at the edge vs centre give different Ct, failed thermal verification, ramp errors.
Root cause: Peltier block ageing / a failed Peltier zone, a heated-lid fault, or a fan / heatsink fault.
Optical / calibration fault (real-time)
HighSymptoms: High background, low signal, dye / ROI or pure-dye calibration fails, poor amplification curves.
Root cause: Excitation LED / lamp ageing, optics contamination, or an out-of-date calibration.
Heated lid / seal fault
MediumSymptoms: Evaporation, condensation on the seal, inconsistent replicates, lid-pressure error.
Root cause: Heated-lid heater or the lid-pressure mechanism / seal.
Software / instrument-comms fault
MediumSymptoms: Instrument not detected, runs will not start or export, firmware mismatch.
Root cause: USB / network link, driver, or the control PC.
Fan / cooling fault
LowSymptoms: Slow ramp-down, over-temperature warning, loud fan.
Root cause: Failed or clogged cooling fan.

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 across a channel or the whole system
- Run fresh controls at all levels and note which analytes fail.
- Confirm reagents are in date, correctly loaded, mixed and not bubbled.
- Run the photometer / lamp-energy check and replace the lamp if energy is low.
- Clean the sample and reagent probes, the mixers and the wash / cuvette-wash stations.
- Recalibrate the affected assay / ISE module and re-run QC.
Symptom: Sample or reagent probe clog / crash / short aspiration
- Inspect the probe for a bend or blockage and clear it (wire / sonicate per the manual).
- Run the fluidics prime and the probe-wash cycle.
- Check for a clot or fibrin in the sample and the liquid-level sensing.
- Verify probe positioning / alignment.
- Replace the probe if aspiration is still short.
Symptom: ISE electrolyte results biased or noisy / ISE calibration fails
- Run the ISE calibration and check the slope / drift against spec.
- Replace an ISE electrode or the reference that is at end of life.
- Check the ISE pinch valves and tubing for wear or air.
- Confirm the ISE standard packs are in date.
- Re-run ISE QC before releasing electrolyte results.
Symptom: High cuvette blanks / position-dependent results
- Run the cuvette blank / photometric check.
- Clean or replace worn / scratched cuvettes or the reaction segment.
- Check the cuvette-wash station nozzles and drying.
- Confirm the water / DI supply quality.
- Recalibrate and re-run QC.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
The connector of the power supply was capable of fitting other components provided with the system. However, the voltage output of the reader power supply is incompatible with the other component and, if incorrectly connected, could result in irreparable damage to the system.
- RECALL
The value for the ANA Cutoff and ANA Positive Controls will decrease overtime resulting in an unusually elevated positivity rate for patient samples tested.
