Calibration SOP

1. Purpose

The calibration of the Burette 25 mL is performed to ensure accurate volume measurements during titration processes 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-0029
  • Equipment Name/Type: Burette 25 mL / Burette
  • Department/Area: QC / Chemistry Lab
  • Process Use: Titration
  • Parameter: Volume
  • Range: 0 – 25 mL
  • Units: mL
  • Calibration Frequency: 365 days

3. Definitions

  • Calibration: The process of verifying and adjusting the accuracy of an instrument against a known standard.
  • Verification: The process of confirming that the instrument meets specified requirements.
  • Adjustment: The act of modifying an instrument to bring it into compliance with specifications.
  • 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 instrument measurements fall outside specified acceptance criteria.
  • Drift: The gradual change in the measurement accuracy 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 range of values within which the true value is asserted to lie.
  • Intermediate Check: A periodic verification of the instrument’s performance between calibrations.

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 calibrations as required.

6. Safety & Preconditions

  • Ensure environmental controls are in place (temperature, humidity).
  • Allow equipment to warm up and stabilize as per manufacturer guidelines.
  • Maintain cleanliness of the equipment and surrounding area.
  • Check that the burette is leveled before use.
  • Verify power supply is stable and within specifications.

7. Standards & Tools

8. Calibration Strategy

Calibration will follow the As Found and As Left logic. A minimum of 5 measurement points will be taken, including endpoints (0 mL and 25 mL) and midpoints (12.5 mL). Each point will have 3 replicate readings to ensure accuracy.

9. Step-by-Step Procedure

  1. Preparation: Gather all necessary tools and standards.
  2. Stabilization: Allow the burette to stabilize in the environment.
  3. As Found checks and data capture: Measure and record the volume at each point.
  4. Adjustment rules: If OOT is detected, follow adjustment procedures or escalate as necessary.
  5. As Left verification: Confirm that the instrument is within tolerance after adjustments.
  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 for the Burette 25 mL is Class A. The error calculation formula is as follows:

Error (%) = (Observed Value – True Value) / True Value x 100

Pass/Fail logic: If the error falls within the acceptance criteria, the calibration is deemed a pass; otherwise, it is a fail.

Rounding rule: [TBD]

11. Handling OOT / Failures

  • Immediate containment: Tag equipment and cease use.
  • Notification & deviation initiation: Notify QA and initiate deviation process.
  • Impact assessment trigger: Define impact window and review 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 of calibration certificates.
  • e-Records if applicable: [TBD]
  • Label content requirements: Include calibrated date, due date, technician name, and status.
