    Anyone tried the "mylar" collapsable "wine in a box" type bags for storing chemicals? I've been using 1 gallon "canning" jars, with rubber ring, but their wide mouth is not too good for pouring.

    I thought the bags might be a great solution- not much air contact, light tight (I think), and a handy spigot.

    I've looked around, however, and I haven't found a good source for these. Anyone know of one?

    No I don't know where to get them, but I would be very interested.

    Wine boxes are often mentioned as chemistry storage - and they are so much fun to prepare since you have to carefully dispose of the contents - - -

    Actually, the concept is used by at least on manufacturer of photo chemistry (Sprint) as a form of packaging of their product.

    While I haven't actually shopped for them, however, I share the concern - - - I don't recally seeing boxes in the wine shop that I go to. Somehow, I have an impression that the wine that would be packaged in boxes is about the same quality as that in bottles with screw tops - so perhaps a megga-store that carries an enormous range of product offerings would be more promising that a small specialty shop.

    You might have to buy them with the wine in them, and force yourself to drink said wine. Here's a brief excerpt from a box wine site:

    Does boxed wine have a limited shelf life even if it is not opened?
    Yes. A bag-in-box wine has a shorter shelf life than bottled wine due microscopic amounts of oxygen that age the wine. This also happens in bottled wine, but more slowly.


    So may not be the best solution for long storage.

    This is all I have found after a lot of Googling:

    http://www.stoutbillys.com/stout/productn/(Flat)/8FD9CAD4.htm

    They don't accept orders online. I emailed them to check availability. Post here if anyone contacts them, or any other good source!

    I tried them for a time and found that the valve got "crudded up" (technical term :smile: ) with dried developer and became very difficult to operate.

    places that sell wine making or beer making [homebrewing] might have them in stock. But from what I remember they aren't for long term storage.

    Have you looked for Cubitainers? These are made of heavier plastic and are meant for chemical storage.

    When I lived in South Africa I used to get some surplus from a local vineyard in exchange for some horticultural consultancy. Getting the fluids in can be a challenge however the keeping power is good because you can expel all the air.
    I used to gaffertape a loop of plastic to one corner and suspend them over the sink.
    Be sure to lable the contents VERY carefully and dont put them in the domestic fridge.

    Mylar bags have to be coated with aluminum to be impermeable to gases. Clear Mylar is not a good choice because of this. Mylar has a very poor puncture resistance, which is why it is mainly/only used for long-term storage as a liner for other containers (cardboard boxes, polyethylene buckets). The fact that Mylar bags are only used for packaging disposable products with a very short usefull life is probably the best indicator that this material is not a good choice for storing photochemicals.

    Cubitainers look like they would fit the bill, but googling only came across specialty companies selling with a huge price tag- one site wanted $83 for a 1 gallon container.

    Anyone know any reasonable source for these?

    I think that Freestyle sells some chemicals already in these boxes. I seem to recall seeing this in the catalogue.

    If you use them, don't store them in your wine cellar, with the regular box wine....LOL

    sprint photochemistry comes in 1 L bottles and larger cubes like you are talking about. they have been selling their photochemistry like this for decades. i think i got some D72 ( solutech?) from the calumet in cambridge mass, in a 5L cube like that 6 or 7 years ago too.

    it keeps well and works well too :smile:

    you could contact sprint and find out where they get theirs, or maybe they will sell you some?

    I have used wine bags for keeping dektol stock for up to one month without any problems but I would not use them for long term storage. I get them from restaurants just buy asking for them.

    Di - hick - dit - hick - ditto!

    I'm pretty sure they're aluminized plastic, not mylar. I swear by them.

    There are also water containers used for camping that are collapsible plastic like these. They are not in a box and I've never used them for this purpose. Just a thought.

    Coffee shops here sell coffee by the gallon in these types of aluminumized mylar (I think that's what it is) bag in a cardboard container with a handle. I haven't tried, but I suspect they'd sell a few without the coffee.

    Delta sells 1 gallon bag in boxes specifically for photo chemicals. I had 3 of them, and while the concept is great, at least with the Delta ones, the caps leaked terribly! I just got rid of the three of them in a fire today (every so often I burn all my extra cardboard boxes in a 55 gallon drum outside my house just for that purpose)

    About 20 years ago, I used to buy Ilford paper chemistry in convenient box with mylar bag inside - it was a great easy solution - don't know why they disappeard.
