Quality Control

Our Poly(3-Hydroxybutyric Acid) is produced and tested under a rigorous quality management system. Each batch is characterized for key parameters including molecular weight distribution, thermal properties, and purity to ensure consistent performance. Certificates of Analysis (COA) detailing specific results are available upon request, supporting compliance with relevant research and industrial material standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). This material is hygroscopic (moisture-sensitive); prolonged exposure to high humidity should be avoided to prevent degradation of polymer properties.
