Sodium Thiosulfate is a key ingredient in the preparation of fixing baths, playing a crucial role in the stabilization of developed film. It's also a common component in various reducers, enhancing the quality and clarity of your photographs.

Our Sodium Thiosulfate comes in the more commonly used crystalline form. When dissolved, this form lowers the water temperature significantly, making it ideal for use in environments with a starting water temperature of at least 90deg.F/32deg.C. If you're working with anhydrous salt, you can substitute it with 64% of our crystalline hypo.

This high-quality, reliable product is offered in a convenient 10lbs bulk size, perfect for photographers who require large quantities for their work. With our Sodium Thiosulfate, you can ensure effective and consistent results in your film development process.
