Quality Control

Our Bromine81 is produced and handled under stringent quality protocols to ensure exceptional isotopic and chemical purity. Each batch is analyzed using advanced spectroscopic techniques, including Mass Spectrometry (MS), to verify isotopic enrichment and chemical identity. A Certificate of Analysis (COA) detailing isotopic purity, assay, and relevant specifications is provided with every shipment to guarantee traceability and compliance with research-grade standards.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated area, away from heat and ignition sources. Recommended long-term storage temperature is between 2°C and 8°C. Keep the container tightly sealed under an inert atmosphere to prevent oxidation and maintain isotopic integrity.
