Calibration SOP

1. Purpose

The calibration of the Bioreactor Pressure Sensor is performed to ensure accurate pressure measurements within the bioreactor process. This calibration is critical for maintaining patient safety, ensuring batch quality, and preserving data integrity. Accurate pressure readings are essential to prevent deviations that could compromise product quality and safety.

2. Scope

• Asset ID: CAL-0303
• Equipment Name/Type: Bioreactor Pressure Sensor / Pressure Sensor
• Department/Area: Biologics / Bioreactor
• Process Use: Pressure
• Parameter: Pressure
• Range: 0 to 3 bar
• Units: bar
• Calibration Frequency: 365 days

3. Definitions

• Calibration: The process of comparing a measurement instrument against a known standard to determine its accuracy.
• Verification: The process of confirming that a measurement instrument meets specified requirements.
• Adjustment: The process of modifying a measurement instrument to bring it into compliance with specified standards.
• As Found: The condition of the instrument prior to any adjustments made during calibration.
• As Left: The condition of the instrument after adjustments have been made and verified.
• OOT (Out of Tolerance): A condition where the measurement results fall outside the specified acceptance criteria.
• Drift: The gradual change in a measurement 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 of a measurement lies.
• Intermediate Check: A verification process performed 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 document results.
• QC/QA Reviewer: Review calibration documentation and results for compliance.
• Owner Department: Ensure equipment is available and in good condition for calibration.
• External Service Provider: Conduct calibration as per external calibration type requirements.

6. Safety & Preconditions

• Ensure environmental controls are in place (temperature, humidity).
• Allow for warm-up/stabilization of the equipment as per manufacturer specifications.
• Maintain cleanliness of the equipment and surrounding area.
• Check leveling of the equipment to ensure accurate readings.
• Verify power supply stability before calibration.

7. Standards & Tools

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

8. Calibration Strategy

Calibration will follow the As Found then As Left logic. The minimum number of test points will be five, including endpoints (0 bar and 3 bar) and midpoints (1.5 bar). Each point will have three replicate readings taken as a best practice.

9. Step-by-Step Procedure

1. Preparation: Gather all necessary tools and reference standards.
2. Stabilization: Allow the Bioreactor Pressure Sensor to stabilize as per manufacturer guidelines.
3. As Found checks and data capture: Measure pressure at defined points and record raw observations contemporaneously (ALCOA+).
4. Adjustment rules: If OOT is detected, follow adjustment protocols as allowed; otherwise, escalate the issue.
5. As Left verification: Re-measure to confirm that adjustments have brought the sensor within tolerance.
6. Labeling + documentation completion: Complete all required documentation and label the equipment with calibration details.

10. Acceptance Criteria & Calculations

Acceptance criteria for the Bioreactor Pressure Sensor is ±1%. The error calculation formula is:

Error (%) = (Measured Value – True Value) / True Value × 100

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

Rounding rule placeholder: [TBD]

11. Handling OOT / Failures

• Immediate containment: Tag equipment and stop use until resolved.
• Notification & deviation initiation: Notify relevant personnel and initiate a deviation report.
• 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 in accordance with company policy.
• e-Records if applicable: [TBD]
• Label content requirements: Include calibrated date, due date, technician name, and status.
