Marathon Liquid Indicating Stop
Bath 5 Gallons (concentrate)
*SEE FREIGHT NOTE*

Freestyle’s exclusive Marathon Chemicals are the answer to high-quality, low-cost bulk B&W chemicals for large school or photo lab darkrooms.

Marathon Indicating Stop Bath is used in processing Black & White photographic film and paper. It is used after the developer, to stop the development, prior to fixing and wash steps.  Acetic Acid stop baths stop development almost instantly and provide more control than a water bath. Water baths require more time to successfully stop development, so use of stop bath speeds up processing workflows. It also preserves the strength of the fixer by neutralizing the developer completely, before the fixer step.

Generally supplied with a sour odor, Marathon Indicating Stop Bath is odorized with a vanilla scent. This stop bath will also change color (to purple) when it is exhausted.

A premium bulk chemical, it has been tested and used by educators from all over the U.S.

Economical 1:9 dilutions for all chemicals make for simple dispensing to students.

Optional spigot available, for easy distribution to students (item #2842475).
