Discussion Large 10L cylinder Nitrogen 99.8% purity or 5L cylinder with food grade 99.99% nitrogen

[martinso67]

In a hypothetical dilemma where I had only the possibility to choose between:
- PRODUCT A#: 10 Liter (2 cubic meter, 70 cubic feet) with 99.8% purity nitrogen
OR
- PRODUCT B#: 5 Liter (1 cubic meter, 35 cubic feet) wth 99.99% food grade purity nitrogen

Both are from a reputable seller and certified. But I can't get anything different. The impurities don't matter in this scale anymore?? Oxygen impurities would be less than 0.2%.

Product A as there is not much difference in purity

This should be fine. 0.2% oxygen is definitely not enough to allow your body to continue functioning. Ambient air is ~21% O2, so this is like 0.9% of the concentration found in ambient air.

I would opt for the 10L tank, as it would be able to flow longer and ensure your heart stops before the gas runs out.

Even 99.0 % Nitrogen is unsurvivable, so get A, the larger tank

I will have to rent a car to transport the gas bottle. The local tools store where I will buy the gas is somewhat too far. I can't take the gas bottle that far by feet.

It was smaller than I thought from the advertisement of the car tools company, but its uncomfortable too hold. So I got a handle straps to strap the bottle package and hold it through the handle of the straps.
The woman who sold it to me was very friendly though. Thought the store seller would be aggressive in trying to upsell me stuff I don't need. It's still a car tools store and they have to earn money someway. But this is still annoying to customers.
