How much does liquid helium cost

[Mk]

No, I'm not thinking of buying one/any, but how much does one cost?, any type. Plus, how much do the two commonmost types of helium in liquid form, and/or liquid nitrogen, cost per gallon? I know liquid nitrogen is cheaper... a lot.

...If I were to not buy in bulk.

A quantum dot isn't really something you can buy. Nitrogen is on the order of a dime a gallon, but that's high volume manufacuring prices. You can't really just go buy 10 gal of it.

No, I ment like at MIT, the cost of constructing one the cost of how much helium they use...

I know a guy, he had ohh... actually about 10 gallons of it in a tank in his classroom.
