You can get phosphoric acid from any chemical supply company, eg Baxter,
Sigma etc. If you work at a University science dept, this will make sense,
if not well it won't, maybe.
For an 8lb jug of 85% phosphoric acid its $45, ouch! I would just go to the
yellow pages and look up some industrial chemical supply houses.
I once needed some 1.5 inch diameter fuel hose (only 1 foot) for a VW, and
could not get it from any Auto parts place accept the dealer who did not
have it in stock and it was SPENDY. So I called an aircraft hose supplier.
He had some bullet proof hose on a 50 000 foot roll and gave me a foot long
bit!!
