Sodium Thiosulfate 3 %

Sodium thiosulfate is a chemical compound used in many fields, including histology and metallography. In a 3% solution, sodium thiosulfate serves as a reducing agent and antioxidant.

In histology and cytology, sodium thiosulfate is used as a fixative and developer in the staining of tissue sections and cell preparations. It plays an important role in silver plating, a technique in which silver ions are used to label specific cell structures. After the silver ions have bound, sodium thiosulfate is used to remove excess silver and ensure a clean, accurate stain.

In metallography, sodium thiosulfate is used as a fixative in what is known as a Baumann impression. This method is used to study the grain structure of metals. The metal is treated with an etching solution and then an impression is taken with a cellulose film, which is fixed with sodium thiosulfate. This allows a detailed analysis of the grain structure of the metal.

In addition, sodium thiosulfate is an important ingredient in the photographic industry, where it serves as a fixative that removes excess silver from photographic emulsions, stabilizing the images. In this context, the process is called development, similar to the process used in black and white photography.
In medicine, sodium thiosulfate is used as an antidote to cyanide poisoning because it reacts with cyanide to form harmless substances.
