Quality Control

Our Sulfuric Acid is produced and tested under stringent quality management protocols to ensure it meets the exacting requirements of industrial and laboratory use. Each batch is analyzed for key parameters including assay, impurity profiles, and specific gravity. A comprehensive Certificate of Analysis (COA) is provided to guarantee traceability and compliance with relevant industry standards. We support customers requiring adherence to specific pharmacopeial (e.g., USP, EP) or reagent-grade (e.g., ACS) specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from incompatible materials such as strong bases, organic compounds, and metals. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed to prevent absorption of atmospheric moisture and changes in concentration. Recommended storage temperature is between 15°C and 25°C.
