Calibration SOP

1. Purpose

The calibration of the Micropipette 100-1000 µL is performed to ensure accurate volume measurements during sample preparation in the Chemistry Lab. This calibration controls risks related to accuracy, patient safety, batch quality, and data integrity, thereby ensuring compliance with Good Manufacturing Practices (GMP).

  • Asset ID: CAL-0023
  • Equipment Name/Type: Micropipette 100-1000 µL / Micropipette
  • Department/Area: QC / Chemistry Lab
  • Process Use: Sample prep
  • Parameter: Volume
  • Range: 100 – 1000 µL
  • Units: µL
  • Calibration Frequency: 180 days

3. Definitions

  • Calibration: The process of comparing a measurement instrument to a known standard to ensure accuracy.
  • Verification: The process of confirming that a measurement instrument meets specified requirements.
  • Adjustment: The act of modifying a measurement instrument to bring it into compliance with specifications.
  • As Found: The condition of the instrument prior to any adjustments being made.
  • As Left: The condition of the instrument after adjustments have been made.
  • OOT (Out of Tolerance): A condition where the measurement falls outside the specified acceptance criteria.
  • Drift: The gradual change in the measurement output of an instrument over time.
  • Traceability: The ability to verify the history, location, or application of an item by means of documented recorded identification.
  • Measurement Uncertainty: A parameter that characterizes the dispersion of the values attributed to a measured quantity.
  • Intermediate Check: A verification process conducted between calibrations to ensure ongoing accuracy.

4. References

  • Company Metrology SOP [TBD]
  • ISO/IEC 17025 traceability via calibration certificates
  • ALCOA+ principles

5. Responsibilities

  • Technician/Metrology: Perform calibration and maintain records.
  • QC/QA Reviewer: Review calibration results and documentation.
  • Owner Department: Ensure equipment is available and in good condition for calibration.
  • External Service Provider: Conduct external calibration as required.

6. Safety & Preconditions

  • Ensure environmental controls are in place (temperature, humidity).
  • Allow equipment to warm-up/stabilize as per manufacturer recommendations.
  • Maintain cleanliness of the equipment and workspace.
  • Check leveling of the equipment.
  • Verify power supply is stable and within specifications.

7. Standards & Tools

  • Reference Standards Required: [TBD]
  • Traceability Statement: ISO17025
  • Certificate Validity Check: Ensure all reference standards are within their validity period.
  • Standard ID: [TBD]

8. Calibration Strategy

Calibration will follow the As Found and As Left logic:

  • Minimum number of points: At least 5 points including endpoints (100 µL, 1000 µL) and midpoints (e.g., 500 µL).
  • Replicate readings at each point: 3 repeats are recommended for accuracy.

9. Step-by-Step Procedure

  1. Preparation: Gather all necessary tools and reference standards.
  2. Stabilization: Allow the micropipette to stabilize in the environment for at least 30 minutes.
  3. As Found checks and data capture: Measure the volume at each defined point and record observations contemporaneously (ALCOA+).
  4. Adjustment rules: If OOT is detected, follow the adjustment protocol; if not allowed, escalate to QA.
  5. As Left verification: Re-measure to confirm adjustments are within specifications.
  6. Labeling + documentation completion: Complete all required documentation and label the equipment with calibration details.

10. Acceptance Criteria & Calculations

Acceptance criteria: ±1% of the measured value.

Error calculation formula: Error (%) = (Observed Value – True Value) / True Value × 100

Pass/Fail Logic: If the error is within ±1%, the calibration passes; otherwise, it fails.

Rounding rule: [TBD]

11. Handling OOT / Failures

  • Immediate containment: Tag equipment and stop use.
  • Notification & deviation initiation: Notify QA and initiate deviation process.
  • Impact assessment trigger: Define impact window and review of affected results/batches.
  • Recalibration after repair/adjustment: Ensure recalibration is performed post-adjustment.
  • QA disposition: [TBD]

12. Records & Retention

  • Logbook entries: Document all calibration activities.
  • Calibration report/certificate filing: Maintain records for audit purposes.
  • e-Records if applicable: [TBD]
  • Label content requirements: Include calibrated date, due date, by whom, and status.
