    How Long C-41 Developer Can Last (Opened Concentrate)

    Say kodak Flexicolor liquid concentrate, opened, then stored in cool basement. Will that last more than a year? I know the part C can go bad rather quickly. Just wonder how quick that is.

    How can one tell when the part C goes bad? I have some and its blue, does that mean it's gone bad?

    if you just opened them for no reason and then closed them, you let air(oxygen) in. In that scenario they will go bad rather quickly. I have a bottle of Part A, B, and C in my hands right now but Part C is a small dark container so I cannot tell the color of the liquid, but I will prepare my batch tonight. If you haven't gotten an answer by then, I will post my follow up. I don't think it would be blue at all though... These are rather clear substances.

    You must store it under a non-reactive gas if you want it to last. I use the Rollei and fill the bottles with butane after each use, it lasts a year no problems.

    If it's gone blue, it's bad. Ditch it.

    It's gone blue, so i'll ditch it. Where do you get butane from?

    Lighters, and refills.

    Do it outside and don't smoke.
    An awful lot of electrons were terribly inconvenienced in the making of this post.

    Nope. Sorry. If it's the Rollei, at least you can buy that part separately.
