Flic Film Low Odour Stop Bath is a citric acid stop bath which stops further development of film when used as part of a standard development, stop and fix process. Using a stop bath neutralizes the developer which definitively sets the development time and prolongs the life of the fixer. The packaging of this product is made with post-consumer recycled resin and comes in a 200gram and 600gram bottle. Mixed 20g (4 teaspoons) to a litre, one bottle will make 10 litres of stop bath. Each litre has a capacity of 12 rolls of film.
