Quality Control

Our Phosphoric Acid, Sodium Salt (1:) is manufactured under a strict quality management system. We offer various grades, including Food Grade (FCC), Pharmaceutical Grade (USP/EP), and Technical Grade, each meeting stringent purity and safety standards. Certificates of Analysis (COA) documenting key parameters such as assay, heavy metal content, and loss on drying are provided with every shipment to ensure traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent caking and absorption of atmospheric moisture.
