Quality Control

Our Poly-DL-Succinimide is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, molecular weight distribution, and performance. Certificates of Analysis (COA) detailing key parameters such as assay, residual solvents, and impurity profile are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent degradation due to moisture absorption.
