I'm not a chemist, but remember that plastic is permeable to air/oxygen,
right? And I don't know that developer degrades when exposed to the
'artificial' light found in the darkroom. I think silver nitrate is light
sensitive as are solutions of silver.
I use clear glass juice jars of various sizes for developer and fixer, using
glass marbles to minimize head space, and then transfer to smaller
jars/bottles when I run out of marbles. Ones with plastic caps work best,
but I find that they all seal tightly. Metal caps on fixer jars get rusty if
I don't use a Parafilm M liner.
