Magnesium Oxide (Heavy) – 250g (LR Grade)

Magnesium Oxide (Heavy) is a high‑purity inorganic compound supplied in a 250g container, suitable for routine use in educational science laboratories. Provided in Laboratory Reagent (LR) grade, this material offers consistent quality for teaching experiments and classroom demonstrations.

Identified by CAS No. 1309‑48‑4 and classified as Not Regulated for transport (UN: NR), magnesium oxide is a stable white solid that is easy to store and manage in school laboratory environments. The “heavy” grade refers to its higher bulk density, making it easier to handle and measure accurately during practical work.

Magnesium oxide is widely used in chemistry education to demonstrate the properties of metal oxides and alkaline compounds, supporting practical and theoretical learning across the secondary science curriculum.
