NINGBO INNO PHARMCHEM CO.,LTD. is a leading supplier of high-quality chemicals, and among our diverse offerings, Sodium Thiosulfate stands out for its indispensable role in the photographic industry. For decades, photographers have relied on the chemical properties of Sodium Thiosulfate to achieve perfectly developed prints and negatives. Its primary function in this context is as a fixing agent, a critical step in the photographic developing process.

The traditional photographic process involves exposing photographic film or paper to light, followed by development in chemical solutions. After development, the image captured on the film or paper is still sensitive to light, meaning it would be destroyed if exposed. This is where Sodium Thiosulfate, specifically Sodium Thiosulfate 99.5%, comes into play. When the exposed film or paper is immersed in a sodium thiosulfate solution, it reacts with and dissolves the unexposed silver halide crystals that remain in the emulsion.

These unexposed silver halide crystals, if left untreated, would darken upon exposure to light, obscuring the intended image. By effectively removing them, sodium thiosulfate ensures that the image is permanent and unaffected by subsequent light exposure. This process is often referred to as 'fixing,' and the quality of the fix is directly related to the purity and concentration of the sodium thiosulfate used. Therefore, sourcing high-quality Sodium Thiosulfate for photographic applications is paramount for professionals and hobbyists alike.

Beyond its function as a fixing agent, the chemical properties of Sodium Thiosulfate, such as its ability to act as a reductant, also find applications in other areas. However, its historical and ongoing significance in creating lasting photographic memories cannot be overstated. When considering purchasing Sodium Thiosulfate, understanding its grade and intended application is key. For photographic use, the industrial grade or a specific photographic grade is typically recommended.
