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 concentrate will keep for 5 years in full airtight bottles and 12 months in half full tightly capped bottles
It will stay fresh as a working solution for 7 days
500ml will make 10 liters of working solution
A full working strength solution will produce 150 135-36 or 120 films or 600 20.3x25.4cm (8x10") RC prints or 300 20.3x25.4cm (8x10") FB prints
Quantity 500ml (17 fluid ounces, approx)

                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.

                          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.

                                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.

                                      I use this along with Ilford DD-X, Rapid Fix, and Edwal LFN to develop my 120 and 35mm film. I've used this product four times so far and I haven't had an issue and the negatives come out great. The films I've used are Ilford HP-5 and Kodak Tri-X 400. This stop bath is easy to mix and use.

                                        This little bottle surprised me with how many batches it makes. A lot of darkroom demos can be given with this small bottle.
