My two bits -
Rodinal is one time use. But you are using 1:25 or 1:50 or even 1:100 such
that you use so little that the one time use is plenty. No replenishment,
no multiple use.
My own prediliction is to decant the 500ml container into 1 oz (30 ml) glass
amber bottles. I keep these tightly capped and use them in succession. No
problem at all. Way back when, I recall a story about a partially used
bottle of Rodinal found in the late 1940s/early 1950s amongst the bombed
ruins during the German reconstruction. Turned out the contents were as
good as new, despite the summer heat and the winter cold.
I don't use any commercial stop. I use two successive water rinses instead.
The rule of thumb with fixers is in room light to toss a piece of
undeveloped film scrap into the fixer - for 35mm, the leader/trailer of the
roll is ideal. Time how long it takes for the film to clear. Fix for
double that time. When the fixing period extends more than 10-12 minutes or
so, time for mix new fixer. Keep the fixer in a dark, cool place.
