Bergger Berstop is a liquid concentrate stop bath designed for black and white films and papers. It is a low odor, citric acid-based formula that stops the development process and helps to prolong the life of the fixer solution. This 1L bottle should be diluted 1:19 for use as a working solution, and the color of the chemistry bath will change when it is exhausted.
