Indeed. You normally have no control over your supply chain . We burned
about a metric ton of N2O the last few weeks. Our supplier only delivers
bottles without dip tube. So we flipped the bottles up-side-down to fill
the run tank. You wouldn't believe how much dirt, rust and other objects
were trapped in the filters (even several O-rings which did not come
from our plumbing for sure). And that was "clean" N2O (Means, no
additives to spoil your balloon party) but not medical grade though.

Yep, we discussed that at ARIS for cooling the nozzle with N2O for
their
5kN hybrid. But N2O probably gets super critical which makes me
nervous :-(
