Quality Control

Our Orthoboric Acid, Potassium Salt is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. All products undergo rigorous analytical testing to meet defined specifications. A Certificate of Analysis (COA) documenting purity, assay, and key physical parameters is available for every batch upon request, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
