Quality Control

Our Polyvinyl Sulfate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for critical parameters such as sulfate content, viscosity, and biological activity. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and performance data is provided with each shipment to guarantee traceability and compliance with your research or production 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 (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed immediately after use to prevent absorption of atmospheric moisture, which may affect performance and stability.
