Exit bag: helium amount and purity... is 97% enough?

[onewayroad]

Looks like you can get them in Australia:

Does that have the same amount of argon as the disposable canister ones I linked to? I'm just wondering if they're too small for the job or not. What's your opinion on them, @onewayroad?

Here's a demo of them:

Hmmn well I actually looked into these and decided that is was not a sufficient volume, but I might have been mistaken. I'm going to do some recalculations when I'm sober because I'm presently completely intoxicated so I will have to get back to you. But they may well be a good option. Fuck. I already bought a regulator and adapters for a normal canister.

I'll get back to you soon.

I'd probably want something that would last 15 litres per minute for an hour, just to play it safe. So maybe these are too small. Fuck imagine if it ran out and youre not even dead yet, just braindead from lack of oxygen. Vegetable for the rest of your life. Fucking hell.

Have a good one mate. Thanks for your help today

Those disposable ones may very well work. But is it worth the risk incase they run out

An environment with less than 6 % oxygen is lethal, if my memory serves me right. Oxygen gives you the feeling of strangulation though.

whats a good excuse to buy argon gas. without them being suspicious. say you have a mig welder or? any ideas.

Change it to nitrogen - its used for food preservation, much easier with cover up story.
Just watch some video on youtube.
