In photographic processing, sodium thiosulfate's primary function as a Photographic Fixer is to dissolve unexposed and undeveloped silver halide crystals from photographic films, plates, and papers, thereby stabilizing the image and preventing further darkening upon exposure to light.
Our 99% purity grade ensures rapid and complete fixation without leaving stains, sludge, or insoluble residues that could damage delicate emulsions or reduce image archival quality.
In medical and emergency response contexts, sodium thiosulfate serves as a vital Cyanide Antidote, officially recognized in cyanide poisoning treatment protocols worldwide.
The 99% pharmaceutical-grade purity is non-negotiable, as impurities could cause adverse reactions or reduce therapeutic efficacy.
Sodium thiosulfate pentahydrate also finds significant use in:
