Teetotaler and developer storage

I have a question about storing developer in the mylar wine bags with spigot. I don't drink alcohol anymore and was trying to source a place to buy some of these bags. I thought I'd look on eBay since that's fast and easy, but I had no luck or don't know how to search for this particular thing. Do I have to take up drinking again or is there a place to buy these at a reasonable price? Anyone out there have a source to share? John W

You need to look for bag in box containers.

They are also called "cubetainers". US Plastic had them for a time, I'm not sure if they still do.
If you like coffee, Starbucks and Dunkin have them, though I'm not sure if they are the mylar coated type.
These may be a possibility too;

Well, I did both of those searches on eBay and come up with a big ZERO. I have checked on other sites and while some companies had them they are now listed as "out of stock".

They are called cubitainers. US Plastic and a few other suppliers have them in various sizes:

Back in the day I used to buy Kodak Ektaflo chemicals mainly because they were packaged this way. It never occurred to me to look for aftermarket cubitainers. Thanks for posting the question! I may buy some of these myself.

The problem with these is that they are polyethylene, which is gas permeable for oxygen, therefore not good for developers.

Unfortunately, most of the wine-in-a-box makers seem to have switched to this material.

The wine product linked to by bdial is probably effective.

If you have a need to store five gallons of developer, this would probably work: http://www.amazon.com/Food-Storage-...srs=13393403011&ie=UTF8&qid=1458662719&sr=1-1

Matt,
That's exactly what I found when I went to two of my local wine & beer making stores. I ask about Mylar bags with spigots and all they hauled out were poly bags and had no idea where I could obtain the Mylar bags. Bummer I guess, but I'll keep checking.

These are polyethylene bags and I'm looking for Mylar.

Here is a manufacturer's site for a product (the "Select Series" at the bottom) that would probably do the job.

Matt,
I tried to find the (the "Select Series" at the bottom) you mentioned, but see no link.

Probably because I forgot to post the link!

Matt,
I agree and think those would work. I went to the companies website and it looks like I would have to be a wine producer to buy from them. It seems to be more of a bulk/wholesale outfit. I used to see Mylar bags with spouts/spigots on eBay all the time, but now they seem to have vanished. Oh well, nice thought anyway.

T-Max developer seems to keep for months in a partially filled plastic soft drink bottle.

I wonder if the concern for oxygen permeating polyethylene is justified. I suspect that it does so at a very slow rate. Otherwise soda, which contains dissolved CO2, molecules that are not so much bigger than O2, would go flat quickly due to the pressurized CO2 permeating out of the bottle.

More to the point, which is better for storing a freshly mixed gallon of developer that gets consumed over a period of months:

A) An impermeable glass bottle, which will have more and more air in the bottle as it is consumed, or
B) A polyethylene cubitainer, which will not allow any new air in, but will have some amount of O2 permeating into the bottle.

Hi JW,

I googled with 'Mylar-D Bladder'. Here is one of the 1st links I got: Dead Link Removed

Bests,
