Calibration SOP

1. Purpose

The calibration of the Micropipette 20-200 µL is performed to ensure accurate volume measurements during sample preparation in the QC department. This calibration controls risks related to accuracy, patient safety, batch quality, and data integrity, thereby ensuring compliance with regulatory standards.

2. Scope

  • Asset ID: CAL-0022
  • Equipment Name/Type: Micropipette 20-200 µL / Micropipette
  • Department/Area: QC / Chemistry Lab
  • Process Use: Sample prep
  • Parameter: Volume
  • Range: 20 – 200 µL
  • Units: µL
  • Calibration Frequency: 180 days

3. Definitions

  • Calibration: The process of verifying and adjusting the accuracy of an instrument against a standard.
  • Verification: The confirmation that an instrument meets specified requirements.
  • Adjustment: The act of altering an instrument to bring it into compliance with standards.
  • As Found: The condition of the instrument prior to any adjustments.
  • As Left: The condition of the instrument after adjustments have been made.
  • OOT (Out of Tolerance): A condition where the measurement falls outside the defined acceptance criteria.
  • Drift: The gradual change in an instrument’s performance over time.
  • Traceability: The ability to trace the history, application, or location of an item through documented records.
  • Measurement Uncertainty: A parameter that characterizes the range of values within which the true value is expected to lie.
  • Intermediate Check: A verification process conducted between calibrations to ensure continued accuracy.

4. References

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

5. Responsibilities

  • Technician/Metrology: Perform calibration and document results.
  • QC/QA Reviewer: Review calibration documentation and results.
  • Owner Department: Ensure equipment is available and maintained.
  • External Service Provider: Conduct external calibration as per schedule.

6. Safety & Preconditions

  • Ensure environmental controls are in place (temperature, humidity).
  • Allow warm-up/stabilization time for the micropipette.
  • Maintain cleanliness of the equipment and workspace.
  • Check leveling of the micropipette.
  • Verify power supply checks are completed.

7. Standards & Tools

  • Reference Standards Required: Calibration weights or standards compliant with ISO17025.
  • Traceability Statement: Calibration is traceable to ISO17025.
  • Certificate Validity Check: Ensure calibration certificates are current and valid.
  • Standard ID Placeholders: [TBD]

8. Calibration Strategy

Calibration will follow the As Found and As Left logic:

  • Minimum number of points: At least 5 points including endpoints (20 µL and 200 µL) and midpoints (100 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 as per manufacturer’s guidelines.
  3. As Found checks and data capture: Measure and record the volume at each test point.
  4. Adjustment rules: If OOT is found, escalate for adjustment as per SOP.
  5. As Left verification: Re-measure to confirm adjustments are within tolerance.
  6. Labeling + documentation completion: Complete all required documentation and label the equipment.

Record raw observations contemporaneously to ensure data integrity (ALCOA+).

10. Acceptance Criteria & Calculations

Acceptance criteria: ±1% of the target volume.

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

Pass/Fail logic: If the error is within ±1%, the result is a pass; otherwise, it is a fail.

Rounding rule placeholder: [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 placeholders: [TBD]

12. Records & Retention

  • Logbook entries: Document all calibration activities.
  • Calibration report/certificate filing: Maintain records as per company policy.
  • e-records if applicable: [TBD]
  • Label content requirements: Calibrated date, due date, by whom, status.
