Got the AZO, ordering the Amidol

10g of Potassium Bromide (chemical formula KBr) will make 100cc of 10% solution. That should last you a while...

So I would mix the 10g with 100 cc of Distilled water and I will be able to store it in a small container and just use 2cc per liter? Easy enough! Any ideas for storage containers that small?

Dunno - I've bought "chem lab authorised" Nalgene bottles in all sized from 100cc to 2liter, just to have enough. I figure you can never have too many bottles - just like trays - and find the 100cc ones really useful for all those fiddly little solutions. Like Pyrocat-HD, or Silver Nitrate for salt prints.

And mixing the 10g with 100cc water is what you're after, yes.

Brian,
I bought small brown glass bottles...Maybe 20 oz? from one of the photo materials suppliers (believe that it was B&H). I imagine that any of the dealers that you have there should have them. If you can't locate them there, you might check a lab supply house. Good luck with the Amidol and Azo...I imagine that you will be in for a pleasant surprise. I know that I was.
