Quality Control

Our Strontium Nitrate, Tetrahydrate is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise chemical and physical specifications, including assay, impurity profile, and loss on drying. Certificates of Analysis (COA) documenting these results are provided to guarantee traceability, consistency, and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture and caking. Separate from incompatible materials such as strong reducing agents and combustible substances.
