Long life chemicals?

[botty]

As a very intermittent film developer/printer I need pointing to chemicals that have long shelf lives.

I have just got a supply of Adox APH-09 which has a 'indefinite' shelf life listed when undiluted. Are there any fixer and stop bath with the same long life?

Water stop bath for economy. Fixer lasts well anyhow.

I develop a lot, but Diafine has a very long shelf life and gets reused, and upon "seasoning" acually gets better with use (enhanced midrange).

Used my first batch for over a year and only made up a new batch because it got excessively foamy (after a while it looks like beer piss). Over the year I used this processed about 1200 rolls of film, but I had to mix more to add to my stock due to the many small loses through wetting the film and minor spillage pouring.

HC-110 in concentrate form has a very long shelf life...
I've been using the same gallon bottle of Kodak Fixer (mixed from powder) for over a year now and it's still working fine...I use this bottle only for fixing film...when I print I mix a fresh batch from Kodak Fixer liquid concentrate...
Ilford Warmtone (Print) Developer concentrate has a long shelf life too...when in its original state...
And of course Rodinal...

Fixer lasts forever, for film development you can skip stop bath, film developers that last long are HC 110 and above all Rodinal - apparently it works even after 50 years.
