Nitrogen 2.8 vs Nitrogen 5.0 gastank

[stupidhuman]

I'm about to buy a tank soon. I believe Nitrogen 2.8 (99,8%) vs Nitrogen 5.0 (99,999%) isn't that important right ?
I'll try to buy a Nitrogen 5.0 if they let me.

I ask because just in case they ask me what I need it for. I've read it's for medical stuff / lab stuff.

So in case no one will sell me I'll get the 2.8 because that's for welding / tires / … - more "home applicable" and less sus than 5.0.

You can just say it's for beer brewing, nitro coffee, or for the kitchen.
About the purity: 2.8 should be good enough, but if you can get higher then that's better of course.

I don't know my gas cylinder's purity, but oxygen measurement was 0.4% after two minutes of flow.

for the kitchen

which use for the kitchen? for preserving food in an oxygen free package?

I don't think they'll be that specific when asking.
(I wasn't asked anything at all.)

Just mentioning beer brewing, nitro coffee or making drinks should be enough.

Thanks. Everything is useful to avoid giving a suspicion of the real intention.
I've recently been reported to suicide prevention services by a toxic asshole that abused me and got scared of the consequences. I hope that such services do not give a list of names to gas providers. Hopefully this is protected by the laws of privacy.

why did you wait for two minutes? and what measurer did you use?
afaik gas cylinder's purity doesn't make a difference - it's made by it's tightness (eg when it's not leaking)

I see thanks, what's the best way to put the bag on ?

It took time for the oxygen measurement to be low enough.
After the first minute, it was 2%, very low, but doubtful.

Whether purity makes that big of a difference, I don't know, but less oxygen is better of course.

The oxygen meter I used was a different one than most others used in the megathread (the Chinese one), but I don't want to put the brand/model here publicly.

I use an EEBD hood.

I found the bag had too many things that could go wrong.

Though I'm not interested in buying an oxygen meter, your reasons on not publishinging the brand/model of this device might help me and other newcomers learn more about how to correctly behave in this forum.

Is it abusive of me to ask you to mention what could go wrong with the bag? I'm still rooting for the bag, but it seems there are some missing things you can help me understand.

Thanks in advance.

It's because everyone can see your posts, including the pro-lifers and law enforcement people who lurk these forums.
They are very trigger happy and will report the sources whenever they get the opportunity.
Besides that, it can also be used to personally identify you (your forum account, or real life identity) if you do proceed to CTB.

The plastic bag is often thin and flimsy. You could easily tear it apart or damage it.
I had a plastic bag previously, and I found that, after approx. 1-2 months of storage, it was no longer airtight. Air was leaking in/around the areas where I put the micropore tape.

It's also quite tedious to make one.

The EEBD hood is pre-made from durable material that should last a while.
You can't easily damage it like you would with the plastic bag.
