A stop bath interrupts the development process and neutralizes the developer so that the fixer does not become deacidified and spoil due to carryover.
ADOSTOP, which is citric acid-based and contains an indicator, is the premium version of a stop bath. It is odorless or, at most, has a pleasant citrusy scent, and it indicates when it has been used up by changing color from yellow to blue-violet.
In film and paper development, ADOSTOP helps you work with precision by immediately halting
the development process.
A stop bath is essential when processing baryta papers, as streaks may otherwise occur.
