    Humm I think the ones I have are sort of moulded together but I will have to check.

    A couple of rinses in hot water is all I did. The residual smell didn't affect the developer properties. Actually, I have graduated from wine bladders to "pure" water bladders. In Australia many supermarkets sell 5 litre boxes of water in bladders. I have used this water to mix up the chemicals and then poured it straight back into the bladder. No residual smell and a healthier liver too!

    Usually I use up my developer stock solutions pretty quick but in this case I mixed up a batch of XTOL in mid July and in the past two months I've only used 100ml from the 1L bottle. I'm doing some new work now and wondering if it's likely still good. And if there are any ways to tell whether XTOL has gone bad (color change etc).

    Thanks

    I mix the full amount and store it in 10 1 litre bottles with plastic stoppers. I dilute it 1:1 for use and use the 1 litre solution to develop either 2 rolls of 120 or 4 rolls of 36. Used like this, I've had my 1 litre bottles keep for well over 6 months. The one time I kept a partially full bottle (500cc) for about 2-3 months and subsequently used it in my normal dilution, the results were pretty poor--no image detail. I think the developer had oxidised although there were no visible signs or smells. Lesson learned: use partially full bottles within 1 month of mixing.

    Square Inches of Emulsion

    XTOL is my favorite because of the less-toxic chemistry. After the prescribed square inches of emulsion have been processed, experience indicates XTOL will become inactive quickly. Remedy: Under-use the developer and discard sooner rather than later. Over-use and replenishment are not cheap if you lose negatives, and XTOL is really cheap stuff. Keep a written record of 'square inches processed' for each batch of developer.

    About bladders: Experience indicates Vitamin-C may extend their life more than other chemistries. I like the accordian-style containers.

    John, can elaborate on the toxicity? My wife will be teaching a high school photography component and she's interested in low toxicity, Eco-friendly methods.

    I hope and think, Roger, that they only appear to be moulded together. The black rim of the dispenser fits very snugly into the translucent ring that is part of the bag itself. Remember these are probably assembled by a machine which rams the dispenser into the translucent ring under quite a bit of power.

    Insert the thin edge of a blade between the black rim and translucent rim very gently at first and lever slowly all round. Once you have a gap then put the thicker back of the blade into the gap and continue levering. Eventually the dispenser will pop out of the first ridge and the gap will then be maybe 1/8th of an inch. Once popped you can use a much thicker lever or even pull with your hands.

    Very occasionally the dispenser has been such a tight fit that I have had to give up and quickly buy another 3L of wine and force myself to drink it quickly so I can try levering out the new dispenser.

    It's a dirty job but someone has to do it

    Response to Tony-S

    Was quoting (always hazardous) popular literature on XTOL toxicity. Kodak makes MSDS (material safety data sheets) available for all their products on their website: search on MSDS. The sheet for XTOL seems to list fewer problem spots than others, but I was surprised to note that although METOL is absent from the formulation as far as I can tell, ascorbic acid (vitamin-C) which is touted popularly to be the active ingredient seems not present. But chemistry is not my strong point.

    The developing agents in XTOL are isoascorbic acid and a form of phenidone.

    Just finished my first batch of XTOL, which was mixed Dec 9, 2011 and was 6.5 months old. It worked perfectly.

    I mixed the 5L of XTOL and then divided it into 10 500mL brown bottles with the phenolic caps, filled to the very top. Just thought I'd add this since the "XTOL failure" meme seems to be evergreen around the interwebs.
