Quality Control

Our Bis(2-Hydroxyethyl)Ammonium Hydrogen Sulphite is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with every shipment to guarantee it meets your technical requirements.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after use to prevent absorption of atmospheric moisture. For long-term storage, consider using an inert atmosphere to minimize oxidation.
