Ilford Ilfostop is a low odor acid stop bath. Normally, when development is completed, films and papers are subjected to a stop bath rinse. This immediately halts the developing process by neutralizing the developer.

Following this, the film or print is exposed to fixer (hypo). The advantage of the stop bath process is that it extends the life of the fixer. Some people do not use stop bath and, in that case, you must use an inordinate amount of fixer to erase the effects of the developer. If a stop bath is not available or chosen, the film or print should be thoroughly soaked in a water bath or rinse - with frequent changing of the water supply. Stop bath gives you the assurance that your developing stage is completely "over" and that none of the developer will be carried over to the fixer.

Ilfostop contains an indicator dye that is pH sensitive and changes color from yellow to purple as the stop bath becomes exhausted. It is specifically recommended for dish and tray processing of paper or deep tank processing of film.

It should be noted that Ilford recommends that gloves, eye protection, apron or overall be worn when handling and mixing all chemicals.

Note: Never let developer become contaminated with a stop bath solution

Ilfostop Stop Bath (500ml) is rated 4.9 out of 5 by 51.
Rated 4 out of 5 by from Low Odor, Easy to Use, Crummy Bottle Kodak stop bath makes 30 liters for the same price, but is so concentrated that it really stinks. The ilford only makes 10 liters, but is easier to work with, not syrupy, and smells neutral. Kodak stop bath and ilfostop are basically identical, except that Kodak is equivalent to three bottles of Ilfostop for the same price. If you don't mind the smell, buy the Kodak instead. The bottle has cardboard underneath, which starts to disintegrate once the foil seal is broken. I had to filter out the paper pulp and pour into a glass bottle. Kodak uses a full plastic cap that has no problems. I pour everything into glass bottles anyway, so this doesn't bother me. Like all Ilford bottles, they are irritating to open with child proof caps. I still give it 4 stars because its nicer to work with if you only develop film on occasion. I shoot enough rolls that I eventually switched back to Kodak stop bath.

Rated 5 out of 5 by from Works like a charm Super-easy to mix and appears to work perfectly. I wish the bottle was more collapsible. If it were, you could squeeze out the excess air to maximize shelf life.

Rated 5 out of 5 by from First Time User Read the technical data sheet online BEFORE you mix the product. Reason I say this is....... nowhere on the packaging that I could find... (and the printing is microscopic), did it state that once mixed, you have seven (7) days to use it. Otherwise than inadequate labeling it was very fast and easy to prepare. Now I know better!! Cheers.

Rated 5 out of 5 by from Ilford Ilfostop Works like a Charm Ilfostop is an indicator stop bath, and even in the darkroom under a safelight, it is easy to tell when it has changed colors, indicating it is used up. The stop bath itself has a slight yellow tint to it, but the tint has not showed up in my prints. Can't go wrong with Ilfostop!
