paying a chemist to make you sn?

[koalamenace12]

ik this is unconventinoal but i feel as if this is a really creative idea that would maybe work?

How difficult is it to obtain SN in the UK? Websites have it listed, but I am sure its not up to snuff for CTB purpose?

Maybe I should make a post on how to prepare it and also assess its purity?

Please !
I've heard you do purity testing with titration, hope there are other ways of doing it because glassware that is "made for measuring stuff precisely" (- like the glassware for titration) can become expensive.

I wonder at what purity-% you can disregard impurities. I've seen people talking about >95%. Anything below is not good.
Is that even achievable at home ?
