Photographers' Formulary 5lbs Anhydrous Sodium Thiosulfate

Over the years, Sodium Thiosulfate has become an essential component in the world of photography, specifically in the preparation of fixing baths and as a key ingredient in various reducers. This 5lbs Anhydrous Sodium Thiosulfate, brought to you by the trusted brand Photographers' Formulary, is a pure, professional-grade, high-quality product designed to meet the exacting standards of photographers.

Unlike its more common counterpart, crystalline hypo, anhydrous Sodium Thiosulfate does not significantly lower the temperature of the water when dissolved. This makes it a reliable and effective choice for photographers who require consistent results. When using the crystalline form, it's recommended to start with water of at least 90 degrees Fahrenheit or 32 degrees Celsius. However, with this anhydrous form, you can use 64% of the salt as a direct substitute for crystalline hypo, offering greater flexibility and convenience.

Whether you're a professional photographer or an enthusiast, this Anhydrous Sodium Thiosulfate is a must-have for your photography toolkit. It's not just a product; it's a tool that helps you achieve the perfect balance in your black and white film development process.
