SOP for Bulk Density Testing in Granules

SOP for Bulk Density Testing in Granules

Standard Operating Procedure for Bulk Density Testing in Granules

1) Purpose

The purpose of this SOP is to outline the procedure for determining the bulk density of granule formulations in the pharmaceutical industry to ensure consistency and quality.

2) Scope

This SOP applies to all personnel involved in bulk density testing of granule formulations within the pharmaceutical quality control (QC) department.

3) Responsibilities

Analytical Chemist: Responsible for performing bulk density testing and documenting results.
Quality Assurance (QA) Department: Responsible for reviewing and approving the bulk density testing procedure and results.

4) Procedure

  1. Sample Preparation:
    1. Select a representative sample of the granule formulation according to sampling plan.
    2. Ensure the sample is adequately homogenized to eliminate any agglomerates.
  2. Apparatus Setup:
    1. Calibrate the bulk density apparatus using a standard calibration weight.
    2. Ensure the apparatus is clean and free from any residue.
  3. Testing:
    1. Weigh the empty measuring cylinder or vessel (V1).
    2. Fill the cylinder with the sample to a specified volume and weigh again (V2).
    3. Calculate the bulk density using the formula: Bulk Density = Mass of Sample / Volume of Sample.
  4. Reporting:
    1. Record the bulk density measurement in the appropriate logbook or electronic system.
    2. Document any deviations or issues encountered during testing.
  5. Documentation:
    1. Maintain accurate records of all bulk density testing activities, including raw data, calculations, and reports.
    2. File documentation in accordance with Good Documentation Practices (GDP).
