Stop bath from the Bellini Eco series. Contains no harmful substances, ideal for use in school.
The Odourless Indicator Stop Bath from Bellini is an inexpensive, universal stop bath that can be used with almost all black-and-white films and photographic papers on the market today. The stop bath is based on acetic acid and is very economical to use with a standard dilution ratio of 1+19. Unlike Bellini's standard odorless stop bath, this stop bath contains an indicator so you know when it is nearly exhausted. It has a yellow-orange color when it is working well, a green color when it is working less well and a blue color when it has almost completely lost its effect. Thanks to its operation, it is therefore a valid alternative to Kodak's indicator stop bath.
The stop bath has the following capacity per liter of working solution:
15-20 films or
60 sheets RC photo paper size 18x24 cm (2.5 m²) or
