Where could I get a small amount of conc. nitric acid?

[stinkwheel]

Concentrated, not fuming.

It's one of those chemicals you need to jump through many hoops to get hold of through official channels and i don't really want or need 2.5 litres.

I have a carb with a brass screw irrevocably stuck and in a near impossible place to get a drill on. I know conc nitric will dissolve brass but not aluminium. Pretty quickly too.

I was wondering if anyone knows of any industrial processes that use it who might be prepared to sell me a little if I knocked on the door and asked nicely. Maybe electroplaters or similar? I have a mate who is a goldsmith, he uses it but his is all pre-mixed aquaregia which is mixed with HCl and that stuff dissolves almost everything.

I think the law has changed in the last few years after that spate of acid attacks. I think you have to have some sort of hazardous substances license now or something.

Maybe the chemistry department of a local college? Buy a lecturer a beer

Special order from a pharmacy?
Does this still apply? -

As a vet I thought you’d have access to all sorts of odd stuff.

Yeah, I thought you might have one in your line of work. So you could buy material to euthanise an animal but you can’t buy nitric acid?

Further research indicates I may well be able to make my own if I get the appropriate glassware.

Acid was far easier to get hold of when I was at art school in the 70s

Although the need has been and gone now, if the need ever arises again I'd have thought the easiest thing to do would be to identify a business that uses conc nitric acid, then take the carb to them and offer a few notes for them to apply the acid in their own facility? That way no rules broken so they're more likely to comply plus they'll have the PPE.
