🔍 Introduction
In pharmaceutical Quality Control laboratories, proper destruction of tested samples is essential to prevent mix-ups, unauthorized reuse, and regulatory non-compliance. A well-defined SOP ensures safe disposal, traceability, and adherence to Good Laboratory Practices (GLP) and environmental safety standards.
🧠 Semantic Content Layer
Pharmaceutical sample destruction involves systematic collection, segregation, neutralization, and disposal of tested materials. This includes handling various dosage forms such as tablets, capsules, liquids, and raw materials. Proper documentation and controlled disposal ensure compliance, prevent contamination, and maintain data integrity in QC laboratories.
