Quality Control

Our Thiosulphuric Acid, Lead Salt is manufactured under strict quality management protocols to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analysis to verify identity, purity, and conformance to agreed specifications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, heavy metal content, and moisture levels.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and away from direct light to maintain stability and prevent degradation.
