[help] Kodak Photo-Flo dilution
Hello,
I purchased a 500ml bottle of Kodak Photo-Flo. It's *concentrated*, but I'm not sure about the dilution. 1:200? 1:600? There's no info on the bottle (only health warnings) Please note it's the french version (maybe different). Thanks for suggestions Roberto (Italy) |

If its PF200, dilute 1:100, if its PF600 dilute it 1:600.

Thanks for suggestions Roberto (Italy) Roberto - The concern with diluting PhotoFlo is not precision, but rather that you want to make sure that the working solution is diluted enough. If anything, it is preferable to use an even greater dilution rate than recommended, especially if the water you use has low mineral content. An alternative, not-so-scientific dilution rate for PhotoFlow 200 is to use the bottle cap as a measure - use one capful of concentrate per gallon (about four liters) of water. Half a cap is even better. The purpose of PhotoFlo is to break down the surface tension of the water. An excessively strong solution will leave a residue on your film that is undesirable. |

Yea, that's right. Use an eye dropper, it works for me.

There's no info on the bottle (only health warnings) The dilution is 1:200. In the US the name is "Photo-Flo 200". I dilute it 1:8 in 91% isopropyl alcohol to make a stock solution. I then dilute this 1:25 for use - using stainless tanks and reels it works out to 10ml per 250ml tank - easy to measure. I find it works best when diluted using steam distilled water. -- Nicholas O.

There's no info on the bottle (only health warnings) Please note it's the french version (maybe different). Thanks for suggestions Roberto (Italy) One possibility is to contact the Kodak office for Italy in Milan and ask. The number is: 39-2-660-28710 I looked for French MSDS on the Kodak web site and found 2 for Photo-Flo without any further name. From the ingredients both appear to be Photo-Flo 600. There is also am MSDS for Photo-Flo 600 under that name. The concentration of ingredients indicate that all three are the 600 variety. The dilution given for working strength of the unspecified kind is approximately 1.67 ml to make a liter, which is right for the Photo-Flo 600 version. The ingredients look about the same as for the US version of Photo-Flo 600. I can't gurantee this is what you have so I think a call to the local Kodak office is in order. Photo-Flo works well at about half the strength recommended by Kodak. A good final rinse consists of: Distilled or boiled and filtered water to 1.0 liter Isopropyl alcohol, 99% 25.0 ml Kodak Photo-Flow, at half the recommended amount whatever that is for the version you have. Isopropyl rubbing alcohol can be used if it doesn't have anything else in it, like Oil of Wintergreen or other flavorings, the amount will be about 35 ml/liter. The amounts are not at all critical. Soak the film in this mixture for about one minute with gentle agitation and hang up to dry without squeegeeing. -- --- Richard Knoppow Los Angeles, CA, USA |

Ken, the european package is a little bit different. At least, this one has no strenght info (200 or 600). Only *Photo-Flo*. Roberto "Ken Burns" ha scritto nel messaggio ink.net... TYPO!!!! If its PF200, dilute 1:200. |
