Figure this out...

So what happens when you mix Argon and Helium inside the bottle?
Would logic not dictate that Argon sink to the bottom and Helium float to the top of the bottle even though they are under pressure.

Darn imteresting. And well answered too..

But it brings to mind:
Do they use different (SCUBA tank) cylinders and mixing tubes for 'Mixed gas', deep sea/saturation divers who have Helium mixed in with thier compressed air?

200 lbs huh? thats alot. My environment is fairly stable and the weather here has been cool lately. No pressure fluctuations at all. just short fills. They usually fill argon tanks to 2000psi (or so they said) Its time for another fill now too so I'll have to give'em the gears again. Maybe he'll drop 10 bucks off the price.

What are you payinfor a fill and how big of a tank. I have 125 cu/ft tanks and im paying $55.oo cnd. (argon)

They use nitrogen generaly when mixing gases and no the tanks are not different, just standard SCUBA tanks.

Don't worry then Signwave, the last bottle I got had 2200psi in it, so me and another guy got the long end of your bottle.

I believe I paid $59U.S. for my last 300cf(330??) bottle of Argon. I think it was $29 for a 125 of 75/25. Can't say for sure, I can't usually get out of there for less than $200.
