X-TOL, Microphen, or Acufine for long shelf life pushing developers?

When you say ADOX XT-3 has a longer shelf life than Kodak XTOL, can you tell me please, what are you basing that on?

see ADOX website

Their English website page for XT-3 does say, "with improved storage capacities compared to earlier ascorbic-acid developer recipes." And, "Better keeping properties" compared to "similar working recipes like Xtol, Excel or LegacyPro Eco."

However, when we move from the general product description to specific recommendations, Adox says,
"Once mixed XT-3 should be filled in dark glass bottles filled to the top or topped up with protective gas (alternatively throw in clean glass marbles to taise the level of liquid). Prepared like this the stock solution should keep at least 6 weeks and up to 6 months depending on storage conditions and depletion of the solution."

The most recent data sheet I can find for Kodak XTOL is from Alaris, Publication J-109 dated Feb 2018. And that data sheet gives the shelf life of stock XTOL "in full, tightly closed containers" as "6 months."

So really, both manufacturers are claiming the same shelf life for the mixed stock solution -- six months -- right?

Actually, the exact wording used suggests Adox XT-3 is good "up to 6 months" (a maximum of 6 months), and Kodak just says "6 months" suggesting a minimum of 6 months?

It's funny, when I go to the Fotoimpex page product page for Adox XT-3 and click on this link for "PDF datasheet" it opens the Kodak Alaris Data Sheet J-109 for XTOL. In some places ADOX is saying XT-3 is "better" than XTOL, but in other places, they seem to be saying, "There is no practical difference"?

Sorry then I had misunderstood you, I thought that by electronic photography you meant hybrid nah no &€ital cameras for me: no light, no pictures

The no light no pictures is a sound plan! I'm so fond of film. I've been known to go for a stop even two, but as others have said all that's really changed is contrast.

I'm a XTOL fan, have been since it debuted. Keeps for a long time in full bottles. It's all about proper laboratory practices. Pure water, full bottles, properly maintained replenished solutions.

Adox makes fabulous chemistry.

Store the developer in StopLossBagsTM using their funnel for filling he bags. www.StopLossBags.com. I have stored XTOL and replenished XTOL for years with problems. Always test the developer with a a strip of film.
