    New Rodinal bottle

    I've just got a new 500ml aoimaging Rodinal bottle. There are whitish sediments on the bottom of the bottle...
    Is that bad?

    I would say proceed with caution. There have been several mentions on APUG of the non-Agfa Rodinal variants having shorter shelf lives than the real Agfa beast which lasts for decades even after opening.

    It is my understanding that in mixing home-brew Rodinal that there should be a few crystals left after the titration.

    I was under the impression that A&O was the company that bought the rights to make Agfa Rodinal when Agfa folded. Or am I getting my companies confused? In any event, my one bottle of Rodinal to date (made before Agfa's demise) has a few solid crystals in it toward the end of its life, but it worked just fine up until the last drop.

    I got three bottles with the sediment at the bottom as well today. I am not worried about it. In my experience this new Rodinal is holding up very well.

    I have a bottle of Rodinal made by AO imaging. It has become dark brown and it has the the sediment you mentioned. It still works nicely.

    That a&o developer is the original stuff.
    (change of company owner; by now it is even another one.)

    The sediment adds character...and a certain grittiness to the images

    It should be fine. Kal

    It should be ok. Sediments and dark color are ok for Rodinal. My rodinal is like that and it works fine.

    It's not a problem. After Rodinal is getting older you will have some crystals on the bottom.

    Rodinal A&O is the original stuff.
    Indeed in the mean time again another new owner of the chemical plant from Agfa.
