Centrifuge Inspection and Recertification Checklist
- Confirm the power supply output voltages match specified requirements for stable distribution to all internal components
- Measure and verify voltages at PCB test points to ensure accurate power delivery and circuit integrity
- Confirm rotor compatibility with the centrifuge model and check that rotor detection systems recognize the rotor type
- Inspect the exterior for any cosmetic or structural damage that could affect performance or safety
- Check the door mechanism alignment to ensure secure and smooth opening and closing
- Inspect and replace the gas strut with an OEM part to maintain proper door support and safety
- Examine the rotor chamber bowl for dents or damage and replace as needed to ensure safe operation
- Replace and confirm full functionality of all lid lock switches to maintain secure closure
- Inspect and lubricate the door lock mechanism, applying grease to the lid lock rail for smooth operation
- Test compressor functionality (if applicable) to ensure proper operation and consistent temperature control
- Conduct an 8-12 hour cycle test to validate consistent performance over prolonged use
- Confirm rotor motor stability, check for unusual noise, and assess mechanical integrity during operation
- Inspect the condensation drain and clear any clogs to prevent moisture buildup in the rotor chamber
- Verify RPM accuracy using an NIST-traceable tachometer and perform calibration as necessary
- Check the centrifuge error log to ensure zero recorded issues, confirming system reliability
