FX100 Black & White Film and Paper Fixer Chemical – Universal.
Bellini FX100 is the fixer we use in our lab. Its very easy to mix, has long shelf life, and a much reduced environmental impact.
Composed of Ammonium Iposolfite it is formulated specifically for black and white films and papers. The nice thing about this fix is that it is easily eliminated thus has reduced washing times and is more eco friendly than some other fixers.
One litre of concentrated fix that should be diluted 1+4 for film and 1+9 for papers
