    TF-4 fixer: Storing leftover concentrate

    I used about one third of the concentrate to fill a 1.5L bottle with working fixer.
    Can the remaining concentrate be refrigerated? I'd like to maximise its shelf-life.

    TIA!

    I stored mine in the plastic bottle it came in, in the basement, in normal basement conditions. It was good three years later. YMMV.
    No idea what's going to happen next, but I'm hoping it involves being wrist deep in chemicals come the weekend.

    I always mix it all at once because the concentrate is not fully dissolved....its possible by mixing just part, you are not getting the right amount of the chemicals in the part you use.

    I always just shake the concentrate really, really well and I've *never* had a problem.

    It will keep longer as a stock solution than mixed, so if you mix it thoroughly and then mix up what you need, you'll tend to be able to keep the unused portion longer.

    A bunch of Nikons; Feds, Zorkis and a Kiev; Pentax 67-II (inherited from my deceased father-in-law); Bronica SQ-A; and a nice Shen Hao 4x5 field camera with 3 decent lenses that needs to be taken outside more. Oh, and as of mid-2012, one of those bodies we don't talk about here.

    Favourite film: do I need to pick only one?

    Same here. Would not know where to store 4 gallons mixed otherwise nor how long so much would take me to use!

    Store the concentrate in a cool but not cold location.
