Quality Control

Our Neopolyoxin B is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for potency and related substances analysis. A detailed Certificate of Analysis (COA) documenting identity, purity, and specific tests is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a desiccated environment to maintain stability and purity. For long-term storage, consider conditions under an inert atmosphere.
