Gel Manufacturing: SOP for Sampling During Gel Manufacturing – V 2.0

Standard Operating Procedure for Sampling During Gel Manufacturing Process


Department Gel Manufacturing
SOP No. SOP/GM/071/2025
Supersedes SOP/GM/071/2022
Page No. Page 1 of 10
Issue Date 02/06/2025
Effective Date 04/06/2025
Review Date 02/06/2026

1. Purpose

To define the procedure for collecting representative samples of raw materials, in-process gels, and semi-finished products during gel manufacturing for quality control testing and compliance with product specifications.

2. Scope

This SOP is applicable to all gel manufacturing processes within the Gel Manufacturing Department of the pharmaceutical unit.

3. Responsibilities

  • Production
Officer: Responsible for coordinating and facilitating sampling activity.
  • QC Analyst: Responsible for collecting, labeling, and documenting samples as per sampling plan.
  • QA Executive: Oversight to ensure sampling activities comply with cGMP and documentation requirements.
  • 4. Accountability

    The Head of Quality Control is accountable for ensuring compliance with the sampling procedure.

    5. Procedure

    5.1 Types of Samples

    1. Raw Material Samples: Collected before manufacturing starts, based on predefined sampling plan.
    2. In-Process Samples: Collected at defined stages to monitor consistency, pH, viscosity, and homogeneity.
    3. Semi-Finished Product Samples: Taken before filling to confirm compliance with bulk specifications.

    5.2 Sampling Points and Frequency

    • Sampling shall be performed at:
      • After initial gel base preparation
      • Post API addition
      • Post homogenization
      • Before bulk transfer for filling
    • Sampling frequency must follow batch manufacturing record (BMR) and product-specific SOPs.

    5.3 Sampling Tools and Containers

    • Use clean and sterile sampling spatulas or pipettes.
    • Sampling containers must be:
      • Amber or white high-density polyethylene jars
      • Sterilized and appropriately labeled

    5.4 Sample Collection

    1. Ensure proper gowning before entering the sampling area.
    2. Label each sampling container with:
      • Product name
      • Batch number
      • Date and time of sampling
      • Sample type and point
    3. Collect the required volume (usually 10–50g for gels) using sanitized equipment.
    4. Seal and transfer the samples to the QC lab immediately.

    5.5 Documentation

    • Record sampling details in the Sample Collection Logbook (Annexure-1).
    • QC to maintain sample receipt records and initiate testing as per internal timelines.

    5.6 Precautions

    • Avoid contamination by using gloves and sterile sampling equipment.
    • Do not reuse containers or tools without proper cleaning and sterilization.

    6. Abbreviations

    • QC: Quality Control
    • QA: Quality Assurance
    • SOP: Standard Operating Procedure
    • BMR: Batch Manufacturing Record

    7. Documents

    1. Sample Collection Logbook – Annexure-1
    2. Sample Label Template – Annexure-2

    8. References

    • ICH Q7: Good Manufacturing Practice Guide for Active Pharmaceutical Ingredients
    • WHO Technical Report Series No. 986, Annex 2 – GMP for Pharmaceuticals
