Barium Sulphate – LR Grade, 500g

Barium Sulphate is a high‑purity inorganic compound supplied in a 500g pack and manufactured to Laboratory Reagent (LR) grade. This white, insoluble powder is widely used in educational science laboratories due to its chemical stability and well‑defined properties.

Identified by CAS Number: 7727‑43‑7 and with no UN number, barium sulphate is not classified as hazardous for transport when handled correctly. Its extremely low solubility in water makes it particularly suitable for demonstrations and experiments involving precipitation reactions and ionic compounds.

Supplied in a generous quantity for repeated classroom use, Barium Sulphate LR Grade is easy to store, measure, and handle, providing consistent results across multiple practical sessions.
