Thanks Brian I'm not sure if the bottles need to be brown  I suspect
they could be clear just as well as they sit there in the dark anyway.
In the yellow pages there is a section called "laboratory supply" and
these people do sell their test-tubes and scales and microscopes and
bottles to the public. You don't need to be a biologist or a drug
dealer! 
I have in front of me my white box of CTL#7322 Qorpak Bottles
on the side it says
Bottle, Amber Br, Blk pV-lined Cap, 8 oz 03a

So the whole time it appears I've been using 8 oz which is 236.59 mls
not 250mls! At least it's consistent!
And it comes in a box of 2 dozen. You'd have 4 left over to use for
something else.
I think that's what they have. Brown. They are more likely to have brown
then clear or another color. So I got brown.
I think it was around 40 bucks.

Perhaps a 10% solution of Benzotriazole for colder tones and clearer
whites in your paper for one of those extra bottles?!

I'm lucky that i have a neat label maker so I type in "Xtol" and then
hit the button repeatedly so i can label all my little Xtol bottles
consistently and clearly and easily. 
I would not leave them unlabeled.

My local supplier is Nurnberg Scientific
Nurnberg Scientific

fax (503) 246-0360

I don't quiet trust plastic to keep developers or fix in. I love glass.
I spend my money on glass.
I guess you could get 4 oz or 125 oz bottles, 40 of them if you always
ran half liter metal tanks.
I don't know what the amounts are for Jobo.
