These bottles are 300ml and made out of rather thick airtight plastic. I make 1 or 2 liters of developer and split it into these bottles and use them one at a time for one or two shot development. The developer keeps very well in these. I just opened a bottle that I mixed 2 months ago and it's in perfect condition. The only trouble is, every time I open developer now, I want to drink it -- the juice tasted soooo good ;-)
Ummm....guys, it is not generally a good idea to put non-potable stuff into beverage bottles, particularly if the original appearance of the bottle is not drastically altered. Kids, in particular, are apt to take a swig on the assumption that it if weren't soda pop, it wouldn't be in a soda pop bottle.
Putting automotive antifreeze (ethylene glycol-based) into two-liter soda bottles is one of the more egregious offenses, since the stuff not only looks sort of citrus-y, it actually tastes sweet and it doesn't take much to kill a youngster.
I can imagine someone mistaking slightly oxidized developer for an herbal tea, and in some cases the taste might actually be better
My father used to store insecticide in soda bottles, until I pointed out how dangerous it could be to his grandchildren. He stopped doing it immediately and I now have a grandchild of my own to worry about.
But then, some people don't have kids......any more........
keeps his veins from freezing in the cold
Ah, yes---the old-fashioned alcohol-based antifreeze. Didn't know you could still get that without paying excise tax on it!
