Flic Film's Allergen-Free Fixer was made for darkroom enthusiasts who may have developed a sensitivity to the chemicals in other commonly used fixers. Odorless, non-hardening, and free of both ammonia and sulfur dioxide, the Allergen-Free Fixer remains effective and easy to use with both black and white film and paper. The fixer contains sodium thiosulfate, or hypo, and Flic Film recommends using their Hypo-Clearing Agent in the final wash to save water and time as well as their Low Odor Stop Bath to lower the chances of a sulfur dioxide reaction during the developing process.

This package has enough powdered chemistry to make one liter of solution.
