Use of Laboratory Balances in the Pharmaceutical Industry – USP <41>, <1251> & Ph. Eur. 2.1.7
From USP <41> to Ph. Eur. 2.1.7—precision begins with the right balance.
Pharmaceutical manufacturing depends on data integrity at every step—starting with weighing. This essential white paper from Sartorius provides a comprehensive comparison of key regulatory frameworks—USP <41>, USP <1251>, and Ph. Eur. 2.1.7—outlining the exact balance performance requirements needed for GxP compliance and audit readiness.
What you’ll learn:
- Minimum sample weight guidelines for accurate weighing in line with USP and European Pharmacopoeia standards.
- Repeatability and sensitivity testing protocols to maintain traceability and reduce analytical risk.
- The role of calibration and how ISO/IEC 17025-accredited services ensure global recognition and metrological traceability.
- Differences between formal and informal chapters (USP <41> is enforceable, <1251> is advisory).
- How to comply with Ph. Eur. 2.1.7. using internal test weights and reduced external testing frequency.
Why it matters:
- USP <41> mandates that balances used for “accurate weighing” meet strict criteria for calibration, repeatability (≤0.10% relative error), and minimum sample weight calculations.
- Ph. Eur. 2.1.7 requires on-site performance testing and repeatability validation using small test weights (≥100 mg).
- The chart on page 7 clarifies how to calculate and verify the minimum sample weight using 2 × σ / m ≤ 0.1%.
- Sartorius offers dedicated certificates to document compliance with all major standards, aiding in audits and SOP documentation.
Regulatory ready. Statistically sound. Proven at scale.
