Biotec Fischer Phero- Sub 2020-E
Biotec Fischer · Model Phero- Sub 2020-E
Electrophoresis System The PHERO-sub 2020-E primarily designed for resolution of high numbers of samples such as from Cloning or PCR. The PHERO-sub 2020-E allows ultra high-resolution separations over extended runs. Tray sizes correspond to standard blotter sizes. It also allows easy sample transfer onto a membrane for further analysis. Three tray sizes are available – 20 x 20cm, 20 x 25cm and a half-length 20 x 10cm.
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.
No or unstable output voltage / current
HighSymptoms: Run will not start, "no load" or "leak" fault, voltage / current will not hold the setpoint.
Root cause: Power-supply output fault, a bad tank / lead connection, buffer-conductivity issue, or a cracked electrode.
Tank / lid / electrode fault
MediumSymptoms: Leaks at the tank, warped lid will not seat, broken platinum electrode wire.
Root cause: Cracked tank / lid or a broken electrode.
Imaging / gel-doc fault (imagers)
MediumSymptoms: Dark or uneven images, transilluminator / LED not working, camera not detected.
Root cause: Transilluminator LEDs / tubes, the camera, or the imaging software.
Temperature / cooling fault (capillary / large-format)
MediumSymptoms: Runs overheat, poor resolution, temperature alarm.
Root cause: Cooling fan / Peltier or a coolant fault.
PC / software fault
LowSymptoms: Runs will not program, images / data will not save or analyse.
Root cause: PC or software / license.

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: No or unstable output
- Confirm the buffer type / concentration and fill level.
- Check the tank leads and electrode connections and inspect for a broken electrode.
- Test the power supply into a known resistor / dummy load.
- Try a different tank to isolate tank vs supply.
- Replace the power-supply output board if it fails the dummy-load test.
Symptom: Gel-doc image or transilluminator fault
- Confirm the transilluminator / epi-LEDs light.
- Check the camera is detected and the lens / filter are correct.
- Clean the imaging surface.
- Replace failed LEDs / tubes.
- Refer the camera module if it is not detected with a good cable.
