ARS-IMAGO ST is an odorless citric acid solution that, when diluted, can be used as a universal stop bath for black and white film and paper.

The use of a stop bath is strongly recommended to stop the developing process with immediate action. The stop bath helps not to contaminate the fixing process, extending the chemical's action and its duration.

The concentrated chemical contains Citric Acid Monohydrate, which has no PBT/vPvB chemical substances.



PREPARATION: ARS-IMAGO ST - ECOSTOP BATH ODOURLESS is a concentrated liquid to be diluted to get a citric acid solution.
Recommended dilution: 1+19 (19 parts of water + 1 parts of chemical = working solution).

TEMPERATURE: The working solution has to be used allowing a maximum temperature difference of 5°C from the developing bath.

AGITATION: Agitate continuously for the whole treatment time.
