I toured a winery that used a large stainless steel tank to dispense wine. The tank had a pour spout at the bottom and a floating lid on top. I was told that paraffin oil was poured over the top of the floating lid, such that it would fill any gaps and provide an inert, air-tight top. As wine was dispensed from below, the lid simply sank with the rest of the volume.
Yes, there are many ways to store photo chemistry: accordion bottle, adding inert objects into the bottle to fill space, hell, even using a smaller bottle! I'm not interested in other methods of storage or even in the stack ranking of these methods against each other.
No, what I'd like to know is, does this method pan out with photo chemistry?
The oil should float on top just the same as with wine, but I'm not convinced of its inertness with photo chemistry.
Edit for comments:
How would you get reusable solutions back into the container without disturbing the sinking lid? It's not like you're drinking the stuff, I hope.
1 part Adonal to 2 parts lime. Float the Grand Marnier and top with soda water. I thought everyone drank these??
Because of my limited time these days, I develop once a month or two and make one-shot's of all chems needed. This process intrigued me for use with off-the-shelf chemicals for before I mix them to working strength. (I have a bottle of fix, for example, that has been between half-full and 1/8 full for almost a year now.)
Question may be a bit cleaner with a list of Specific target chemistry. - Real question is how much reaction between a given chemistry and oil can take place, as it should not actually ever come in contact with the chemistry if done properly.
See above comment. Because of my own process, I'd be keen to learn of any reactions with all steps: Developer, Stop, Fix, Perma-Wash. I don't think Photo-Flo actually goes bad so, let's not worry about that one.
