How much does a cylinder of nitric oxide cost?

[Mark R]

We use this at our hospital. But there's a big sign on the cylinder saying turn off immediately it's not needed, because it ridiculously expensive.

So, any ideas how much it costs?

P.s. That's Nitric oxide (NO) not nitrogen dioxide (NO2) or nitrous oxide (N2O)

I know a guy who knows a guy who "found" a cylinder of nitric oxide. He's willing to let it go for $20, PM me if you're interested.
