Obtaining LN2 in the US

[bh2k]

How would I be able to obtain LN2 in the united states? I hear it's very difficult and you need many permits. Any truth behind this?

[kommando]

I thought you didn't permit, just the big cool container.

[toyman]

I just picked up 10 litres of Ln. No permit no big deal

LN2 is used in ranching (bull semen!) and chemical process control. Not too hard to get. The yellow pages is a place to start, check out compressed gas places - if they don't have it they'll usually know who does.

I was told I may have probs, because my dewar is missing it's "tops" or lids.... although we know it can't be a sealed type lid??

How much do these high quality cans cost?

ebay is your friend.

I looked into it, local compressed gas company had it, and they will let you use a dewar, just put down a deposit, refundable when you bring it back.

or ebay own your own.

can it be stored a long time ?

[charlie]

a high quality dewar may hold it for several days... but it will "shrink" day by day.

put it in the freezer!

You also want to store it in a well-ventilated area, as it "shrinks" and gasses off you could get high concentrations of gaseous Nitrogen. Not good if it adversely upsets the Oxygen percentage in the air you breathe.
