1. Purpose
This SOP provides a comprehensive procedure for operating filling machines used in the production of sterile injectable products. It ensures equipment is operated under validated, controlled, and aseptic conditions to maintain
product integrity and regulatory compliance.
2. Scope
This SOP applies to trained production personnel operating automatic or semi-automatic vial/syringe filling machines in the sterile injectable manufacturing area.
3. Responsibilities
- Machine Operator: Operates the filling machine as per validated parameters and records necessary observations.
- Production Supervisor: Verifies setup, ensures readiness of the equipment, and monitors operational compliance.
- QA Officer: Performs in-process checks and verifies batch-related documentation.
4. Accountability
The Head of Production is accountable for ensuring that filling machines are operated only by trained personnel and as per validated procedures.
5. Procedure
5.1 Pre-Operation Checks
- Ensure the machine is clean and labeled with “CLEANED” status tag.
- Verify the availability of the approved Batch Manufacturing Record (BMR).
- Check the line clearance and ensure the area is free from previous product residues.
- Verify the calibration and validation status of the filling machine.
- Ensure HEPA filter airflow and environmental conditions meet Class 100/ISO 5 standards.
5.2 Machine Setup
- Install the filling needles, peristaltic pump tubing, and sensors as per equipment configuration.
- Adjust the filling speed, volume, dwell time, and nozzle height as per the batch-specific requirements.
- Secure vial/syringe nests or conveyor alignment according to container format.
- Record all setup parameters in the Equipment Setup Log (Annexure-1).
5.3 Operation
- Switch ON the machine and run a dry cycle for 10 seconds to confirm smooth operation.
- Load the sterile injectable solution under LAF in aseptic conditions.
- Begin the fill operation with initial 10 vials as trial run. Verify volume accuracy with digital scale.
- Start production fill cycle once QA confirms trial batch.
- Maintain visual inspection of fill level, drips, and machine performance continuously.
- In case of vial jam, leakage, or misfill, press emergency stop and resolve with QA intimation.
5.4 Post-Fill Activity
- Remove all unused materials from the filling area.
- Print and attach “Filling Completed” status label to machine.
- Clean the machine as per SOP for cleaning and record the activity.
- Document fill weight results and line stoppages in the Filling Log (Annexure-2).
