Stability Chamber Calibration and SOPs

Stability Chamber Calibration and SOPs: Best Practices in Pharma

Stability chambers are essential equipment in pharmaceutical manufacturing and testing environments. They simulate precise environmental conditions to evaluate the long-term, intermediate, and accelerated stability of drug substances and products. Regulatory agencies such as the FDA, EMA, and WHO mandate the use of calibrated and qualified stability chambers to ensure that drug products retain their quality, safety, and efficacy throughout their shelf life.

Calibration Failures and How to Document Corrective Actions in Pharma

A calibration failure, also called an Out-of-Tolerance (OOT) event, occurs when the actual reading of an instrument deviates beyond the acceptable range from the reference standard. In stability chambers, this often refers to temperature or humidity readings falling outside ±2°C or ±5% RH of the expected value during a calibration check or mapping.
