Quality Control

Our Pipes Sesquisodium Salt is manufactured under a quality management system and undergoes rigorous analytical testing to ensure it meets the stringent requirements of research and industrial applications. Each batch is tested for identity, purity, and specified impurities. A comprehensive Certificate of Analysis (COA) detailing assay, pH, endotoxin levels (where applicable), and other critical parameters is provided to guarantee batch-to-batch consistency and traceability.

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 product is hygroscopic (moisture-sensitive). Keep the container tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
