Blimus, I remember 326 wetting agent. I must have had a bottle for around 10 years before it ran out or went off (can't remember which)!
Quote: To minimise their oxidation I would fill the space in the bottle with glass marbles to reduce the volume of air.
..or use concertina bottles, if you can get 'em or spray lighter refill gas into the partly filled bottles (prevents oxidisation) making sure you don't blow yourself up in the process Powders last pretty much indefinitely but liquid concentrates are more convenient. I don't think there is any difference in quality whatsoever and each type has its adherents. Perhaps you might like to try Rodinal as a developer? This is a liquid concentrate with very good keeping qualities (running into years I am not too reliably informed). Trouble is, it's quite difficult to get hold of these days and you may not like the results (it's an 'acutance' developer). My choice would be ID11/D76 powder.
