Potassium Hydroxide Pellets Pure – 500g (LR Grade, UN Classified)

Potassium Hydroxide Pellets Pure 500g is a high‑purity Laboratory Reagent (LR) grade alkali supplied for controlled educational use. Commonly known as Caustic Potash, this solid inorganic compound has the chemical formula KOH and is widely used in school and college laboratories to support the teaching of acids, bases, and neutralisation reactions.

Supplied in pellet form within a clearly labelled 500g container, potassium hydroxide is highly soluble in water and produces strongly alkaline solutions. As a corrosive substance, it must be handled by trained staff and students under supervision and stored in accordance with COSHH regulations and school laboratory safety procedures.
