The Ilford Simplicity Film Fixer is a liquid concentrate designed for black-and-white film. One sachet is enough to fix two 35mm rolls or one 120 roll in a 600ml developing tank. This non-hardening fixer permanently stabilises the film after development, forming part of the essential develop, stop, fix and wash process. Ideal for both beginners and advanced photographers, it offers convenience without the need for fix hardeners.
