Quality Control

Our Sodium Hydroxide is produced under stringent quality management systems to ensure batch-to-batch consistency and reliability. We offer various grades, including Industrial, Technical, and Food Grade (FCC), with specifications tailored to meet the demands of your specific application. Certificates of Analysis (COA) documenting purity, assay, and impurity profiles are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed in a cool, dry, and well-ventilated area, separate from acids and organic materials. Store at room temperature (15-25°C).
