I am looking to make a high pressure air/CO2 stream. I have a mixing system which generates a 120 psi stream, which I then want to compress to 1500 psi. We do this with CO2/N2 now without issue, I was concerned that the O2 at this pressure would require special equipment. Does any one know...
Debate going on whether or not cylinder ring stands (heavy rings that attach at the base of the cylinder) are appropriate for standard 44 liter cylinders. Does anyone have any documentation on this either way?

I saw a presentation of a thermo haake extensional rheometer, which extended a drop of fluid and measured the diameter with lazers, and then did calculations based on surface tensions.
Has anyone any experience with these instruments
