Ilford Ilfostop Stop Bath (500ml)

Description

Ilford Ilfostop is a low-odor liquid-concentrate acid stop bath for black-and-white film and paper processing. Used after development, it neutralizes developer before the fixing stage, helping keep developer carryover out of the fixer.
Clear end to the development stageThe 500 mL concentrate makes 10 L of working solution. A pH-sensitive indicator dye changes from yellow to purple as the solution becomes exhausted, giving darkroom workers a visible cue during processing.
