Very interesting but a bit expensive.  According to the attachment you get
2 bottles of CO2 (and some valves) for 900 European Currency Units.  That
corresponds to 828 US$ (exchange rate 1 ecu=0.920275 US$).  As some of you
may recall the "Ring test" for hydrogen was about half as much.  I doubt
that many university labs will afford this. Why does this test have to be
so expensive?
