Maintain Backup Stability Chambers to Prevent Data Loss in Case of Failure

Understanding the Tip: Why backup chambers are essential: Stability chambers are critical infrastructure in pharmaceutical QA. A sudden malfunction—due to power failure, temperature controller breakdown, or refrigerant issues—can jeopardize months or years of collected stability data. Having backup chambers validated and ready allows immediate transfer of samples, minimizing data loss and avoiding major protocol deviations….

Handling Out-of-Trend Results in Long-Term Stability Studies

Handling Out-of-Trend Results in Long-Term Stability Studies Best Practices for Managing Out-of-Trend Results in Long-Term Stability Studies Out-of-Trend (OOT) results in long-term pharmaceutical stability studies are deviations in data that, while still within specification, fall outside expected variability patterns. Unlike Out-of-Specification (OOS) results, OOT events are subtler but can signal product degradation, analytical errors, or…
