    Rodinal - how long does it keep......

    How long does Rodinal keep in unopened new bottles. I have one which is probably around 3-6 years old.

    Thanks for any advice,
    Matt

    3-6 years unpoened. It should be fine.

    I think a lot longer than 3-6 years, I read somewhere they found a pre war bottle in the rubble of Dresden in the late 1950's/ early '60s,tried it out and it worked just fine.

    The WWII vintage wasn't the longest find. I heard a story about the two original bottles Noak brought with him on the Ark, they were still working well when they were found. tim

    Last year I was given a partially used bottle of Rodinal; came in a glass bottle with a rubber cork. I have no idea how old it was, probably decades old. It was almost black in color, but worked just fine.

    I wonder if the longevity is different between Rodinal in older glass bottles and the newer plastic ones? Plastic doesn't keep air out as well as glass does, I have been told.

    But then again, I never keep it for very long, I like to use it too much...

    I've got a two year old bottle that is getting quite dark red, but still produces results consistent with those from years ago. I have some bottles that have been unopened for at least one year, perhaps two, that have very little color at all from what I can see through the bottles.

    As we have seen, the color of Rodinal is no guide as to its quality. The lack of color of XTOL is no guide to its quality.
    Dilute a small amount of Rodinal 50:1 with water and aerate it thoroughly. See how dark that small amount of oxidized Rodinal can make the solution.
    The test of Rodinal is in the use. When you get worried, do a snip test. In fact, you should do one with a new bottle just for the record. Keep the result for comparison with later tests.
