Sorvall WX Ultra Series
Sorvall · Model WX Ultra Series
Easy to Operate. Set RPM or RCF: No protocol conversion necessary. Real-time control: Sample ready when you are – set delayed start/stop. Program memory: Save time by storing up to 20 programs into memory along with User ID and comments. Color touch screen: Easy selection of run parameter and operation. For routine spins, simply enter speed, time and temperature parameters. Dual display of SET and RUN conditions allow you to verify performance at a glance. Run scheduling: Reserve the centrifuge for a future day and time Outstanding Control with UltraSecur™. User lockout feature prevents unauthorized access. Run scheduler allows you to schedule runs at your convenience. Rotor life management tracks rotor usage and alerts you when rotors need to be serviced or replaced Excellent Space Savings and Efficiency. Quiet Operation (53dBA): Eliminates noise distraction so you can place it in the lab where you work. Energy Saving: Less than 20 amp load reduces power consumption up to 15% over the competition and eliminates burden on HVAC systems. Better Ergonomics: 3” lower deck height for easier rotor loading/unloading; door opens with just a push. Smaller footprint utilizes less of your valuable lab space. Imbalance-Tolerant Drive: Saves time with visual tube balancing Easier Sample Loading for Safer Separations. Unique StepSaver™ rotors use cartridges to streamline sample loading and unloading steps, minimizing sample loss. SureSpin™ rotors prevent swinging buckets from being loaded improperly, avoiding sample loss, run shut-downs and rotor failures.
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 / error at start
- Confirm mains power, the mains switch, and check the instrument fuse / circuit breaker - replace a blown fuse (a second blown fuse means an internal fault).
- Confirm the lid is fully closed and the lid interlock is engaging.
- Confirm a speed and time (and an approved rotor) are set.
- Note any displayed error code and look it up in the manual's error table.
- Re-balance the load if an imbalance is indicated.
Symptom: Lid will not open
- Confirm the rotor has fully stopped and mains power is present.
- Press down on the front of the lid while pressing the release button.
- If a power failure, use the mechanical emergency lid release per the manual.
- Inspect the lid-lock solenoid / latch and its micro-switch.
- Replace a jammed or faulty lid-lock assembly.
Symptom: Excess vibration / will not reach speed / noise
- Stop and re-load the rotor symmetrically - opposing positions equally loaded, all carriers fitted.
- Inspect the rotor pockets and chamber for debris or a broken tube.
- Confirm the rotor is fully seated and not corroded or cracked (retire per its use-life log).
- Turn the rotor by hand and feel the drive bearing; on belt-drive units check belt tension and, on older units, the motor brushes.
- Verify speed with a tachometer after any drive work.
