I had Rodinal fail once. It was the last 10ml in the bottle. Other than that, never a problem, but I make sure I toss the remaining few mls.

In my long search for the Original RODINAL, back in 2008, the conclusion was that it was traded under the name Adonal (adox) or Blazinal for the Canadian market.
R09 was AGFA's developer prior to Rodinal. In general, it is differentiated from Rodinal by its 1:20 and 1:40 dilution recomendations.
Back in 2008/09, there was a huge confusion with the Rodinal iterations. R09 was traded as "R09 New", and it was different than R09.
But you know what? listen to xmas, he seems to care a lot. I don't care as much. I use ADONAL and now RODINAL ADOX and I know it is the original Rodinal.
If your stuff goes bad, then it is not Rodinal.
And I recomend Ilfosol-3 if you like Rodinal.
Recently bought 2 500ML NOS bottles of Agfa Rodinal. It's a dark tea color and has some precipitate crystal. Looking forward to using it for a long time. Yeah I prob'ly paid too much,oh well.
would you mind to share some photos of those please?Recently bought 2 500ML NOS bottles of Agfa Rodinal. It's a dark tea color and has some precipitate crystal. Looking forward to using it for a long time. Yeah I prob'ly paid too much,oh well.
Yes but why use a scientific approach when you can guess![emoji15]A clip test of a scrap of film leader in a small amount of diluted developer will tell us a lot. Mix up 50ml or thereabouts of working solution and place a small piece of film leader in it and 'develop' for the appropriate time. This can be done in daylight.
Fix the film scrap and inspect. It should be very dark and this will indicate the condition of you Rodinal concentrate.

He, He. No offense taken. I'm currently about 10% through a 500ml bottle of Adox Adonal which I always top off with Protectan spray after use. It is getting to the colour of moderately brewed tea. I only use it for slower films which tended to be rather infrequently. I have recently snared bulk rolls of Rollei Retro 80s and Pan F so I will be testing it before use on these films.
I hope my bottle goes the distance as developer availability in Sydney took a big hit when one of our larger photo stores closed shop. From what I can see of buying Rodinal in the US it is involves Hazmat restrictions. Shipping liquids is also expensive weight wise. Never mind, I still have 2 x 500ml bottles of HC-110 which are still straw to light honey colour and reputedly has a half-life of several human generations. (Look for it on the Antiques Roadshow in 2115). :confused:
I would limit the term Rodinal to that produced by Agfa and not any copycat versions as made by other manufacturers. When made correctly Rodinais a thick, violet to purple liquid. It is not the black, tarry stuff sold by some companies who do not go to the additional stage of purifying their p-aminophenol. I have been using Rodinal since the 60's and can attest to the color of a freshly opened glass bottle.

Very strange I've used Rodinal in various guises for over 30 years and although it can go off it doesn't suffer from sudden death, normally it loses activity very slowly.
I'm guessing here but it's possible that your Rodinal might have suffered from cross contamination with fix or stop bath, if so it will smell of ammonia.
Does your bottle look like the one on the left?
If so this developer, now over ten years old looks like Coke and still works
Extremely unlikely. I mix up the working solution having nothing on the table except the Rodinal bottle, a jug and a siringe. I also avoid cross contamination with water because first I put the dev, close the bottle and then fill up the jug with water.
Mine looks like Coke and it's in a bottle like this

I ran a test from 1898 to 2008. New Rodinal was decanted from white plastic to brown glass bottle as new. I did a test strip exposed under studio lights for uniformity every six months. Strips were identical for ten years when they started to lighten slightly.
