A bit worrying is this. I had always thought that water bottles with a PET label were OK for developers In fact I thought that I had seen numerous posts to that effect Can you say which developer ate through such bottles and over what time periodGlass bottles and either Butane or Bloxygen will keep your developers practically forever. I've had some last for a year and a half mixed. It is a simple solution. Simple is always best. One spritz of Butane out of a refill bottle is all I do. Easy peasy.
Avoid water bottle type plastics. The developer will eat through it. Been there, done that. Mess....
Is this a ludicrous thought, or do you think it could possibly work?
Honestly if you are looking at Ilford Multigrade developer, you don’t need any tricks at all. Keep the mixed batch in a full bottle and it’ll last some months. The original stock can be in the original Ilford partially filled bottle for a couple of years with air and all and it’s not an issue.
I've had a 500ml bottle of Multigrade that had 100ML removed last year. I opened it this past week and the remaining 400ML had turned as brown as kombucha tea. It printed though....

Wine blathers sounds intriguing. But three problems pop to mind.
- Punctures. How likely are they and how many reuses?
- Are we certain they are really gas tight?
- And are we certain that the plastic doesn’t react with the developer and fixer?
Well bladders for wine are not reused and they are probably not handled in “affect” while processing (unless you count cooking/development wine).Punctures and gas permeability would rule them out for wine use, and they've been in photographic use long enough by now we'd know if they were prone to attack by developers. Enophiles probably only use them once, for fear of contaminating a new batch -- and that's probably not a bad idea for us, but if you can fill it, you can wash it out, and low levels of impurities from residue of the same stuff (last batch) are much less problem for developers than they would be for wines.
Mind you, the stock solutions you'd store in one are less alkaline than some one-shot concentrates, but that's okay -- I don't think anyone has proposed storing (for instance) Rodinal concentrate in a wine bladder.
I can state absolutely that I am sure I blather intriguingly when I have had wine. In fact, I am what is called a wine blather It is possible that others might not share my view of how intriguing my blather is, of courseWine blathers sounds intriguing.
Too much beer. ;-)I can state absolutely that I am sure I blather intriguingly when I have had wine. In fact, I am what is called a wine blather It is possible that others might not share my view of how intriguing my blather is, of course

As you empty them, they collapse rather than letting air in.How would wine bags be better apart from being lighter?
I just had a thought. It's a scary thought, but none-the-less a thought.
I can only get to my dark room, which is 2.5 hours away, about twice a month.
You might try using a pint size Mason Jar, in which you take a 9ml thick silicon or nitrile bag or glove, fitted to the inside by streching the cuff inside by slipping it over the jar mouth down far enough that, with some corn starch, the metal ring lid will move smoothly when tightened down.
Instead of the standard lid top, the second part of the 2 part lid, cut a good fitting soft silicon membrane, about 2 - 3 mm.
You can before hand (no pun) tie each of the fingers closed at the base of 'the sack' or no, just to see how it works out.
Close the jar, with the developer/chemical in place, up to the brim, and lid tightened.
To use a syringe, insert the needle, with a properly sized needle, no larger than a inch or so, then turn/hold the jar upsidedown, and withdraw the need volume needed.
DO NO INJECT AIR INTO THE JAR.
The sack should slowly collapsible, as liquid is withdrawn, the silicon lid membrane is 'self-healing' and you should no have to hard a time no punctuating the glove sack.
If some of our chemists here on photrio.com can decide if either of the materials used in gloves, plus vinal and rubbers, and give their 'OK', then there's no reason no to try this for yourself.
IMO.
I would question why your darkroom is 2.5 hours away? Why don't you bring it closer, or move?
What ever happened to the method of replacing liquid with marbles?
