I used to homebrew and have stored chemicals in the brown bottles for several years. Along with a cheap hand capper, no problem. In the US, in most states we have a bottle deposit. In Michigan its 10 cents per bottle. Go into a good beer store and they will sell you returned bottles for 10 cents. I have an assortment of 12, 16 and 22 oz. Lots better and cheaper than the plastic bottles.
I have also used 1/2 gal clear booze bottles for some things. Its in the darkroom and is usually dark.
If the same thing, here and perhaps there known as

Actually they are 1/32 through 1/2 liter.
Georges and I highly recommend the Polycone or Polyseal
caps; a screw cap with an inserted likely PE cork.
I keep no partially filled bottles. I use a splits method
for all my chemistry. For example a liter of fresh stock
goes into four 1/4 liter bottles. All final dilutions are
done at time of use; no working strengths
hanging around. Dan
So much easier and safer to use something else. Sandy Kings Pyrocat HD is a lot more reliable.
I agree with Dan here throw it away and go for Pyrocat HD.
Another good place for glass amber bottles is stores that sell armoatherapy products - especially of the do-it-yourself type. Often the bottles are nice and small (10ml, 30 ml, 50 ml) as well as the bigger ones and this is good for storing individual amounts of developer. One website is, for example, http://www.quinessence.com/aromather...les_&_jars.htm

I understand that iron is often the culprit in Xtol deterioration. Iron ions are common in tap water. The easy way to avoid them is to use distilled or deionized water. Many common home water purifiers have a deionizing function that will work. It may also be possible to sequester them. I understand that succinate works; EDTA-Na may work.
Why worry about ounce sizes. 250, 125, and 65 ml bottles should work fine, although they leave a bit of air space. You can probably get away with a bit more dilution to avoid that, if you need to.
Such is the case with Boston Rounds; amber at least and

If needed I top up leaving space for the cork within the
screw cap of both the Polyseal and Polycone caps. My
one ounce are off the liter fraction 1/32; not
31.25ml but 34ml. Dan
This is basically the reasoning Ryuji Suzuki presents in one of his Web pages. He claims that salicylates work well to solve the problem, and this is the approach he uses in his DS-10 and DS-12 developers. I don't know if adding salicylic acid to regular XTOL would have any beneficial effects. FWIW, XTOL already uses a preservative that's related to EDTA.

I run Xtol 1+1 and a 5-liter package would never last a year! That's only enough for about 30 rolls of 35mm or 20 rolls of 120/220. Maybe a month or two
