Introduction In pharmaceutical and microbiology laboratories, even a 1 mg deviation can invalidate an entire batch analysis. Improper balance calibration is one of the hidden root causes behind OOS (Out of Specification) results, assay failures, and audit observations. Balance calibration is not merely adjusting a weighing instrument. It is a scientifically validated process that ensures traceability, accuracy, repeatability, and compliance with GMP requirements.
