I just know that they can grow in the diluted working solution of any wetting agent. I also believe that the concentrate has enough anti-bug character that the bugs don't grow there, but I have no proof. I believe that this can only happen in diluted solution though due to carry in of 'bugs' from tap water, or from handling. You can see the growth as either thin threads of matter or slug like 'floaters' in the photo flo solution. This is true of any surfactant and should be watched for. They will burst, spread and vanish.Īs for keeping. I can give a short list here if anyone is interested, but I don't recommend them, as the photoflo will do the job (or any equivalent nonionic surfactant will do) even with the bubbles. There are low foam wetting agents available if you wish. Please watch out for them for the reason I gave above. Some other wetting agents sold for photography are ionic. This is another strike against using soaps or detergents as wetting agents and the reason why Kodak went to a nonionic surfactant in the current Photo Flo. Looking again at using soaps, I must add that soaps are ionic surfactants and can react in water with high calcium content to form scum. The presence of thiocyanate in the Sistan would make it very useful to use at the lowest possible dilution. It is good that there is a wetting agent in Sistan. Tom Lehrers "Periodic Table" was quite poetic as was his "Eternal Triangle" (I've forgotten the correct name of that latter song sung to a Liszt Rhapsody). Gee David, I thought some organic nomenclature was quite poetic and that some poetry was trash. I have not looked at Sistan data or MSDS for a year or so. If dilute enough, there would be no problem at all. Since Sistan contains a thiocyanate salt, I would personally want to rinse it before drying to prevent crystals from forming if nothing else. I was not aware that Sistan had any surfactant in it, and I also thought that it was recommended that the print be rinsed after use of Sistan. There are many substitutes for photo flo out there. Then your film or paper can stick together in humid weather. The disadvantage to using soaps is that they contain dyes and fragrances which can color or leave oily droplets on film and paper. The one other ingredient is a poly alcohol, also readily available. You can probably order it through the Formulary. Triton X 100 is a non-ionic surfactant that is readily available. Read our guides? Looking to stock up on film developing chemicals? We have everything you need Developer, Stop, Fix and Wetting Agent.The formula for Photo Flo 200 is in the MSDS. You can explore further and look at How To Stand Develop Film and Pushing and Pulling Film. Once you’re ready to go, find your Black And White Film Developing Times. How To Prepare Film Developing Chemistry will explain how to get your chemicals ready for processing. Both guides will walk you through each step of developing film at home.Īlso, check out How To Develop Film At Home for a list of everything you’ll need. If you would like to learn more about developing your own film, you should read our guides How To Develop Black And White Film and How To Develop Colour Film. Make sure you mix together thoroughly before use. That means one part Photo-Flo to two-hundred parts water. To prepare your wetting agent, dilute Kodak Photo-Flo 1+200. So, we think it’s worth the small extra cost. With a high dilution, a bottle will last you a long time. While a wetting agent isn’t an essential step in developing film, it will make your life much easier when you come to scan or print your negatives. You then take the film out, wipe off any excess and then hang it up to dry. It will allow the film to dry in a more uniform fashion and thus prevent the marks.Īfter development, stop, fix and wash, you simply leave your film in the wetting agent for about a minute. You should use it as a final rinse before you hang your film up to dry. This will greatly reduce the risk of drying marks left on film after development. Using Kodak Photo-Flo Wetting Agent will help your film to dry quickly and evenly. Description Kodak Photo-Flo Wetting Agent 473ml
