Rodinal version with best shelf life

Hello there! Now, of course I've heard the stories about the infinite shelf life of Rodinal - but it turns out, it doesn't apply to all chemistry that is sold as Rodinal/R09/such substitutes. In particular I've heard about Fomadon R09 getting bad after just one, two years (I have a bottle of that one opened about a year ago... will have to test it but I'm not exceedingly hopeful about it). Are you familiar with any brands of Rodinal that actually have that famous long shelf life? Adox seems promising to me, but if you have any other ideas, do let me know

Cant you just buy a smaller bottle and use it up within 6-12 months or so? That way you don't have to worry about a super long shelf life.

And yes, Adox Adonal does last long. I think that's equivalent to the original Rodinal. Some other concentrated developers are long-lived as well; original HC110 comes to mind, but also Pyrocat HD in glycol.

The longevity is also related to the containers used for it - some of the historically long-lived stuff was in dark amber glass bottles with robust rubber equipped lids.

You are correct Matt. I remember the old glass rubber stoppered bottles from the 60's and that stuff had a half life of decades. As the plastic bottles arrived it began to degrade faster.

Adox formula, anyone?

Glass, Boston Brown Bottles with good inert lab caps should be a blessing, no?
