Quality Control

Our Polyetherurethaneurea-Polypeptide Block Copolymer is produced under stringent quality management protocols. Each batch is characterized for critical parameters including block composition, molecular weight distribution, and endotoxin levels to ensure consistency and suitability for advanced biomedical applications. Certificates of Analysis (COA) detailing specifications for research or GMP-grade material are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C for long-term stability. This material is hygroscopic (moisture-sensitive) and should be handled under dry, inert conditions (e.g., nitrogen or argon atmosphere) when opening to prevent moisture uptake and degradation.
