Quality Control

Our Asinex-Reag Bas 13743909 is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including purity assay and identity confirmation. Certificates of Analysis (COA) detailing specific results are available for every shipment upon request, supporting your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended long-term storage temperature is 2-8°C. Allow the sealed container to equilibrate to room temperature before opening to minimize moisture ingress.
