Iodine Solution with 1% Potassium Iodide – 2.5 Litres

Iodine Solution with 1% Potassium Iodide is a ready‑prepared laboratory reagent supplied in a large 2.5 litre container, ideal for regular use in educational science laboratories. The addition of potassium iodide improves the solubility and stability of iodine in solution, ensuring consistent performance during classroom experiments and demonstrations.

This solution does not have an individual CAS or UN number (CAS: n/a, UN: NR), as it is a formulated laboratory reagent rather than a single pure substance. Supplied clearly labelled and ready to use, it eliminates preparation time and supports safe, efficient science teaching.
