    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.

    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.

  6. 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.

  7. 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.

    Ken,
    the european package is a little bit different. At least, this one has no
    strenght info (200 or 600). Only *Photo-Flo*.

    Many thanks to everyone,
    I will call Kodak Italy in order to give an *official* info on that product
    (200 or 600 version?). Maybe 600, Richard. In the meanwhile, all suggestions
    was very precious and much appreciates!
    Yes Louie, in any cases of doubt, I believe it's preferable to use a greater
    dilution.
    I'll wait till monday, when I will contact the customer care and post the
    answer by Kodak.

    Thanks again
    Roberto Ricco'
