Rodinal - original recipe?

[Patrick Robert James]

I just find it interesting, if anyone had anything different. I have made the PaRodinal, and it works great, but just doesn't have the shelf life of my Adox 500ml bottle that's 2 years old and going strong. It's easier just to stock up and pay $15 and be done, but it's still fun to mix my own from time to time...

Greg, the first bottle of Gainer's EZ Rodinal I made lasted three + years with no problems, and I mixed it with household chemicals. Sulfite from Leslie's Pool Supply and Roebic drain cleaner for hydroxide.

Adox is certainly no going to reveal the recipe of what they sell. In a way this whole thread is of little consequence. There are as many formulas for "authentic" Rodinal as fleas on a hound. Unless someone has made a serious mistake they will all produce very similar results. Believe me I have been down this road before.

Well Adox is actually selling two versions of Rodinal:

Rodinal/Adonal: “last version of Rodinal from Agfa/Leverkusen”

APH09: Orwo R09 from ORWO/Wolfen “close to the 1945 version of Rodinal”

I think there are also versions of R09 from maco/compard and Foma available.
