Sorvall Legend 14 Personal Mic
Sorvall · Model Legend 14 Personal Mic
Easy to use. Rotors and tubes are inserted and removed with minimal effort. A large LED display simplifies viewing of parameters and eliminates any confusion. Setting parameters is also fast and simple using a single knob - no need to bother with toggling arrow keys or imprecise analog controls. A snap to clean: its plastic rotor is fully autoclavable and non-corroding, and the unit features a brushless motor that offers years of maintenance-free operation. Maximum productivity. Operating at 14,500 x g, it can hold 12 micro tubes from 0.5 to 2.0 mL and supports smaller volumes with adapters. Excels in a wide range of applications including nucleic acid purification, PCR cleanup, plasmid mini-prep, protein processing and forensics. Its fast spin up/spin down offers significant time savings that increases productivity - so you can accomplish much more in less time Compact and quiet. 76.5 square-inch footprint (delivers consistent results without taking center stage on your bench-top). Exceptionally quiet so you can conduct your research all day long without distraction.
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.
Will not start / error at start
HighSymptoms: Error code, run will not begin, or aborts shortly after start.
Root cause: Set speed exceeds the rotor maximum, an imbalanced load, the lid / door not locked, an unapproved rotor, or a drive / control fault.
Will not reach speed / excessive noise or vibration
MediumSymptoms: Slow spin-up, rumble, or vibration during a run.
Root cause: Load imbalance, worn drive / motor bearings, a worn drive coupling, or (older units) worn motor brushes.
Timer / speed inconsistency
MediumSymptoms: Run ends early / late, or RPM does not match the setting.
Root cause: Tacho / speed-sensor drift or a control-board fault.
Lid / door will not open or lock
MediumSymptoms: Lid-lock error, will not open after a run, or will not lock to start.
Root cause: Lid-lock solenoid / switch fault, or a run still winding down.
Rotor / bucket wear or corrosion
MediumSymptoms: Visible corrosion, cracks, or a bucket that will not swing; imbalance trips.
Root cause: Rotor / bucket ageing - a safety-critical wear item with a use-life limit.

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: Will not start or errors at start
- Confirm the set speed does not exceed the fitted rotor's maximum and the rotor is approved and seated.
- Rebalance the load - opposing positions evenly loaded and paired.
- Confirm the lid / door latches and the lock engages.
- Look the fault code up in the manual and follow the remedy.
- Functional-check speed and timer after any repair.
Symptom: Noisy / vibrates / will not reach speed
- Rebalance and re-run empty to confirm.
- Spin the rotor by hand and feel for bearing roughness.
- Inspect the drive coupling and (older units) the motor brushes.
- Replace the worn component.
- Verify speed with a tachometer and confirm smooth running.
