Thermal Cycler Inspection and Recertification Checklist

Validate that the power supply and PCB consistently deliver accurate, stable voltages across all circuits and connections, confirming operational reliability

Thoroughly inspect the display for any dim, flickering, or dead pixels, replacing compromised segments to ensure clear visibility and precise data display

Verify complete functionality and responsiveness of all buttons and knobs, confirming accurate and reliable input across all controls

Ensure the machine completes all internal diagnostic checks with zero errors, indicating system readiness and functional integrity

Confirm the machine accurately identifies attached blocks (96-well, dual 48, etc.), with seamless recognition across different configurations

Conduct a detailed inspection of internal wiring and all electrical connections, checking for any signs of breaks, disconnections, or tears; replace or repair any underperforming components

Examine the connector between the block and base for bent or broken pins, replacing as needed to maintain secure, reliable connections

Calibrate well temperatures with a NIST-traceable thermometer, verifying accuracy and uniformity across all wells to meet specification standards

Perform a comprehensive cosmetic inspection, ensuring all exterior surfaces and components are free of damage, wear, or defects, maintaining aesthetic and professional quality
