Quality Control

Our Reinecke Salt is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability for sensitive analytical applications. Each lot undergoes comprehensive testing, including assay, identification, and impurity profiling. A Certificate of Analysis (COA) detailing purity, physical characteristics, and test results is provided with every shipment to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, open flames, and incompatible materials. Due to its light-sensitive nature, prolonged exposure to direct light should be avoided to maintain stability.
