where can you get liquid nitrogen?

Ok...so where exactly can you buy liquid nitrogen? do you need some sort of permit? I mean i work in a lab and we have a bunch of LN canisters but they are huge and most hold 100 gallons or so.

Can the average joe pick some up somewhere?

  1. Try medical supply stores.
  2. We use it out of the huge tanks but occasionally someone's late in filling them so I just go down to the local gasses outlet. They sell LN, helium, dry ice, etc. I live in the wine country where LN is used a lot so I'm not sure if they have these stores all over the place.
  3. try a wielding slupply place my friends dad worked at one and he was able to get some to bring to class to use for stuff
