Product Overview
Trisodium Phosphate Dodecahydrate (Na3PO4·12H2O), commonly referred to as TSP, is a premium ACS Reagent Grade compound. This highly soluble, crystalline material acts as a robust buffering agent and pH adjuster in aqueous systems. Meeting the stringent purity criteria of the American Chemical Society (ACS), this grade is specifically refined for analytical capability, ensuring low levels of impurities that could interfere with sensitive chemical reactions.
As a versatile alkali, TSP supports buffering in phosphate systems, effectively raises pH in cleaning formulations, and aids in hardness adjustment for water treatment. Its low heavy metal content and high assay consistency make it the preferred choice for quality-critical workflows in analytical laboratories, chemical processing, and environmental testing. The product is supplied as a white, odorless crystalline powder, packaged to prevent clumping and ensure ease of handling.
