Introduction
Volumetric glassware plays a critical role in chemical analysis, where even minor deviations can compromise results. Proper handling, calibration, and maintenance are essential to ensure accuracy, compliance, and safety.
This SOP provides a comprehensive, QC-compliant framework for handling volumetric glassware in laboratories, aligned with industry best practices and audit requirements.
1.0 OBJECTIVE
To lay down the procedure for proper handling of volumetric glassware used in chemical analysis.
2.0 SCOPE
This SOP applies to all volumetric glassware used in laboratory and quality control environments.
3.0 RESPONSIBILITY
Officer/Executive – Quality Control (QC)
Responsible for handling, inspection, and documentation.
4.0 ACCOUNTABILITY
Manager – Quality Control
Ensures compliance and approves records.
5.0 PROCEDURE
5.1 Operation (Handling & Usage)
- Inspect newly received glassware for quality and defects.
- Return any broken or unsuitable glassware to the supplier.
- Store glassware in a designated chemical glassware cupboard.
- Issue glassware as required for analysis.
- Ensure users handle glassware carefully to prevent breakage.
- Destroy any broken glassware immediately as per safety guidelines.
- Re-check glassware after cleaning and drying for cracks or defects.
5.2 Calibration of Volumetric Glassware
- Calibrate glassware at the time of issuance and before use.
- Use only Class ‘A’ certified glassware or calibrated equipment.
- Follow the standard SOP for glassware calibration.
- Record calibration results in the logbook.
- Obtain approval from an authorized person.
- Ensure results are within acceptable limits before approval.
5.3 Cleaning & Storage
- Clean glassware using approved cleaning methods and solutions.
- Rinse thoroughly with purified water to avoid contamination.
- Dry completely before storage.
- Store Grade ‘A’ borosilicate glassware separately in labeled cupboards.
- Maintain segregation to avoid mix-ups and contamination.
5.4 Documentation & Compliance
- Record all calibration and handling activities.
- Maintain traceability of issued glassware.
- Ensure records are reviewed and signed by authorized personnel.
6.0 ABBREVIATION
- SOP – Standard Operating Procedure
7.0 CALIBRATION CONTROL CHECKLIST
- Glassware inspected before use
- Calibration performed as per SOP
- Results recorded accurately
- Approval obtained
- Only compliant glassware used
