Help Really struggling to source pure nitrogen canister in the uk.

[apple2024]

The ones that say 99% purity are fitted with a BS3 valve which apparently means they are non toxic??

Many are 'oxygen-free' but I suspect contain a high proportion of CO2 which will give suffocation effect.

Anyone found a reliable source?

The alternative I have found is 90% helium but I suspect this would have enough oxygen in it to make it difficult to suffocate.

I've been having the same trouble in the UK. I might have to try using a helium tank, even if it doesn't work, I have to try.

Same issue here...

Not sure what you mean by " non toxic"? Nitrogen gas is certainly not poisonous…the air w3 breathe consist# mostly of nitrogen. As I understand it the reason it becomes lethal is by breathing a high concentration of nitrogen ( 99%). there is no oxygen content and the brain becomes deprived eventually leading to suffocation due to unoxygenated blood. Correct me if I'm missing something.
