Moersch Citric Acid Stop Bath 500ml

The use of citric acid-based stop baths has the advantage of being largely odorless compared to acetic acid. This effect is somewhat reduced by carrying over developing chemicals into the stop bath, but the climate in the darkroom becomes significantly more pleasant with such a citric acid bath. Dilution to working solution 1+30 to 1+40 Dilution to 2% solution 1+28 (36ml to 1 liter of water), a dilution of 1+40 is completely sufficient to interrupt development.
