The ADOX Adostop ECO is an environmentally friendly and efficient tampon brush that is indispensable for photo processing. This innovative concentrate with its citric acid-based formulation ensures fast and reliable shutdown of film and paper developing processes while protecting the environment. An integrated indicator provides simple and visual feedback on the effectiveness of the chemical, making it easy to track its use.
Dilute the concentrate according to the specifications (usually 1+19) and use it as an acid stopper after the call-up process. The colour change of the solution helps to determine the optimum timing and indicates when a refresh is required.
