Sodium Hydroxide / Caustic Soda 25 %

The 25% caustic soda (sodium hydroxide, NaOH) is a caustic alkaline solution used in various scientific and industrial applications. In chemistry and biology, 25% caustic soda is often used to adjust the pH of solutions and media because it is a strong base and thus can raise the pH.

In histology and cell biology, caustic soda can be used to remove proteins and lipids from tissue samples. In microbiology, caustic soda can be used to break down bacterial cell walls and provide access to intracellular structures and substances, which is important for the extraction of nucleic acids and proteins.

In addition, 25% caustic soda has applications in industry, for example in the manufacture of soaps and detergents, the
neutralization of acids, the treatment of wastewater, and in the paper and textile industries.
In metallography, 25% caustic soda can be used as an etchant for aluminum welds (aluminum alloy/ pure aluminum/ hard aluminum alloys), and for macroscopic weld evaluation. The 25 % sodium hydroxide solution provides a high-contrast image of the individual weld layers and the heat-affected zones.
