Calibration SOP

1. Purpose

The calibration of the Micropipette 1-5 mL is performed to ensure accurate volume measurements during sample preparation in the QC Chemistry Lab. This calibration controls risks associated with accuracy, patient safety, batch quality, and data integrity, thereby ensuring compliance with regulatory standards.

2. Scope

• Asset ID: CAL-0024
• Equipment Name/Type: Micropipette 1-5 mL / Micropipette
• Department/Area: QC / Chemistry Lab
• Process Use: Sample prep
• Parameter: Volume
• Range: 1 mL to 5 mL
• Units: mL
• Calibration Frequency: Every 180 days

3. Definitions

• Calibration: The process of verifying and adjusting the accuracy of an instrument.
• Verification: The confirmation that the instrument meets specified requirements.
• Adjustment: The process of correcting an instrument to ensure it meets the required specifications.
• As Found: The condition of the instrument before any adjustments are 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 an instrument’s output 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 verification process performed 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 period 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: [TBD]
• Traceability Statement: ISO17025
• Certificate Validity Check: Ensure calibration certificates are current.
• Standard ID: [TBD]

8. Calibration Strategy

Calibration will follow the As Found and As Left logic. A minimum of 5 calibration points will be taken, including endpoints (1 mL and 5 mL) and midpoints (3 mL). Each point will be measured in triplicate as a best practice.

9. Step-by-Step Procedure

1. Preparation: Gather all necessary equipment and standards.
2. Stabilization: Allow the micropipette to stabilize as per manufacturer guidelines.
3. As Found checks and data capture: Measure and record the volume at each calibration point.
4. Adjustment rules: If OOT is found, adjust the micropipette according to manufacturer specifications; if not allowed, escalate to QA.
5. As Left verification: Re-measure the adjusted points to confirm compliance.
6. Labeling + documentation completion: Complete all required documentation and label the equipment with calibration details.

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

10. Acceptance Criteria & Calculations

Acceptance criteria for the micropipette calibration is ±1%. The error calculation formula is as follows:

Error (%) = ((Observed Value – True Value) / True Value) x 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: Schedule recalibration post-adjustment.
• QA disposition: [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: Include calibrated date, due date, technician name, and status.
