Ilford Ilfostop stop for black and white films and papers. 500ml pack.

ILFORD ILFOSTOP is a low-odor, citric acid-based stop that effectively and immediately stops the development of photographic paper or film. By neutralizing the developer, it prevents it from entering the fixer bath, significantly extending the life of the fixer and maintaining its potency.
ILFOSTOP suspension is recommended for rinsing all black and white films and darkroom papers after development. It is excellent for both pool printing and deep tank film development. It is a very high-yield liquid concentrate: one 500 ml bottle can produce up to 10 liters of ready-to-use solution.
