Sodium hypochlorite 3%, consisting of an aqueous dilution of sodium hypochlorite, is a ready-to-use solution that has multiple applications in medical diagnostics, histology, metallography and scientific laboratories. The solution is ideal for use in histology and cytology to dissolve mucus and act as a fixative or cleaning agent. In materialography, it is used to prepare etching solutions.

Chemically, sodium hypochlorite is a compound with the formula NaOCl, whose main component is the strong oxidizing agent hypochlorite ion (OCl-). The chemical composition of this ready-to-use solution is composed of a content of 3% sodium hypochlorite and 97% aqua dist. / deionized water, which makes it characterized by excellent solubility and stability.

The application of sodium hypochlorite 3% can give different results depending on the purpose of use: In histology, it can assist in the staining and preparation of tissue specimens, while in materialography it contributes to the effective etching of metal surfaces.
