Standard Operating Procedure (SOP): Operation of Tablet Hardness Tester
Purpose:
The purpose of this Standard Operating Procedure (SOP) is to provide detailed instructions for the proper operation of the Tablet Hardness Tester. This SOP ensures accurate and reliable measurement of the hardness of tablets, which is an essential parameter for quality control in the pharmaceutical industry.
Scope:
This SOP applies to all personnel involved in operating and maintaining the Tablet Hardness Tester in a pharmaceutical or quality control laboratory.
Responsibility:
Laboratory personnel: Responsible for performing tablet hardness measurements as per this SOP.
Quality Assurance (QA): Responsible for reviewing and approving this SOP.
Procedure:
4.1. Equipment and Materials:
Tablet Hardness Tester
Sample tablets
Tablet holding fixtures or adapters (as required)
Cleaning materials (lint-free cloth, brush, etc.)
4.2. Pre-Operational Preparations:
4.2.1. Ensure that the Tablet Hardness Tester is clean and free from any residue or contaminants from previous measurements.
4.2.2. Familiarize yourself with the specific operating instructions and technical specifications provided by the manufacturer for the particular model of the Tablet Hardness Tester being used.
4.2.3. Gather all necessary equipment and materials.
4.3. Calibration:
4.3.1. Before starting any measurements, ensure that the Tablet Hardness Tester is properly calibrated according to the manufacturer’s instructions.
4.3.2. Calibrate the apparatus using appropriate standards or reference materials with known hardness values.
4.3.3. Document the calibration process and results as per the laboratory’s standard operating procedures.
4.4. Sample Preparation:
4.4.1. Obtain a representative sample of tablets from the batch or lot to be tested.
4.4.2. If necessary, prepare the tablets by removing any coating or film to expose the tablet core.
4.4.3. Ensure that the tablets are at a suitable temperature and humidity level, if specified by the test method.
4.5. Measurement Procedure:
4.5.1. Set up the Tablet Hardness Tester as per the manufacturer’s instructions, including the appropriate tablet holding fixtures or adapters.
4.5.2. Place a single tablet in the tablet holding fixture or adapter, ensuring proper alignment and positioning.
4.5.3. Apply gentle pressure to the tablet until it breaks or fractures. Avoid excessive force that may damage the tablet or the equipment.
4.5.4. Record the hardness value displayed on the Tablet Hardness Tester for the measured tablet.
4.5.5. Repeat the measurement process for the desired number of tablets, as per the specified test requirements.
4.6. Calculation and Interpretation of Results:
4.6.1. Calculate the average hardness value for the tested tablets.
4.6.2. Compare the average hardness value to the specified acceptance criteria mentioned in the relevant pharmacopeias standards or internal quality control guidelines.
4.6.3. Document the results in a suitable format or data recording system.
4.7. Post-Test Procedures:
4.7.1. Clean the Tablet Hardness Tester after each measurement, following the cleaning procedures specified in the standard operating procedures.
4.7.2. Dispose of any waste generated during the measurements, adhering to appropriate waste disposal guidelines.
Records:
5.1. Maintain a record of the calibration process, including the date, equipment used, and results obtained.
5.2. Document the details of each tablet hardness measurement conducted, including the date, sample identification, method used, calibration details, and hardness values obtained.
5.3. Retain the records in a secure and organized manner as per the laboratory’s document control procedures
