    If you're concerned about Xtol failing suddenly, consider using Ilford DD instead.

    Sudden XTOL failure is a problem that was addressed and corrected many years ago by Kodak. Any develop will go bad if not tightly sealed. All developers risk going bad given enough time.

    Basic Good Lab Practice: If this is a concern for any developer, take a small piece of film and test the developer prior to use.
    Warning!! Handling a Hasselblad can be harmful to your financial well being!

    Nothing beats a great piece of glass!

    Keith I take it that your reference is to DD and not DDX. The link certainly is to DD. However I tried to recall ever seeing it on any retailer websites, couldn't and so checked but failed to find it.

    I then tried Harman Express and there was no mention of it. Putting in a search only got me to DDX although clearly DD exists. However the tech specs for it only seem to cover large capacity dip and dunk and all temp refs are to mid 70s F.

    Maybe it isn't generally available to home darkroom users?

    Do you know where it can be obtained and in what size containers?

    This is getting away from the OP's thread but just in case he or others wish to consider using DD then the info might be useful.

    Interestingly Harman doesn't seem to state it lasting any longer than the bulk of Xtol users have said that Xtol will last if kept properly i.e in airtight containers

    The DDX sheet says;
    "Full, unopened bottles of ILFOTEC DD-X will keep
    in good condition for two years. Once opened,
    use within three months and keep bottles tightly
    capped.
    Diluted ILFOTEC DD-X should not be stored."

    Thanks for the responses everyone.

    Regarding the comments about DD or DDX though, I've got a lot of experience with DDX and I would not consider it an XTOL "equivalent" as I've seen people suggest in the past. They are really not the same. DDX is a PQ formulation and is a closer match to TMAX developer in its working properties, not XTOL.

    Maybe it is a special order item, but it's listed on Ilford's website.
    Simon Galley would know for sure.

    I've found PC-TEA to give me results that seem to me identical to what I was getting with xtol. Since I wasn't using xtol very frequently that's what I switched to. PC-TEA seems to keep for ages. I had xtol fail in the past but it seems that issue has been addressed. It happened a number of times and I just didn't feel I could count on it. Glad to hear others find it so reliable.

    I don't think XTOL goes bad any faster than any other developer. The problem I have with it is that it doesn't go all brown and stinky when it oxidises. One can do a snip test before every use (and one should), but the time I forget the test is the time the developer goes off.

    Although it will change color, XTOL stops working long before it turns pail yellow.

    I find the benefits of XTOL do not outweigh the costs incurred in re-shooting a roll when it, like all developers, fails.

    So, does it matter if you can still smell residual wine in the bladder? I've washed the one I have half a dozen times but I can still smell the wine in it.

    That would be a seasoned bladder!
