FOMACITRO 250 mL

FOMACITRO is a liquid concentrate of a stop bath (interrupter), designed for use in manual processing of all types of black-and-white films and papers. Developing substances contained in the emulsion layer after development are neutralized by Fomacitro solution, their reduction effect is removed and development process stops immediately. Eventual exhaustion of the stop bath is indicated by a colour change from yellow-orange to blue-green; then it should be replaced with a fresh working solution. The stop bath temperature should correspond to the previous bath (developer) temperature within the tolerance range of 5 °C.
