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
