Production Of Oxygen
« on: April 20, 2002, 09:31:00 AM »
What's up folks?! I'm looking for a way to produce oxygen with a sep funnel and a reaction vessel; simple set-up. I'm not looking for the cheapest way, but I do want it to be as pure as possible. Any info would be much appreciated! Peace! 8)

Search google, I think you'll find some small easy set-ups

Oxone and MnO2

30 percent hydrogen peroxide and MnO2 is easy, cheap and OTC.

Thanks folks! I'll probably use 30%H2O2/MnO2, because platinum electrodes, nichrome or graphite rods, and this thing is a little too involved for me.

Peace! 8)

I have to ask?

Why not just go to the local welding supply store and buy a small cylinder of compressed gas?

You might even find free cylinders on that famous Lab Supplies auction bay. Search for gas.

How Small ??

"You might even find free cylinders on that famous Lab Supplies auction bay."

  Normally that would be a good idea, but as far as compressed gas goes, that's a no-no for me, because you don't know how many times the seller dropped it and bashed the valve. If the valve's damaged, a piece could fly off and blow a fucking hole through your skull when you crack it open. Yeah, a welding supplier's a good idea. I haven't been in the welding world too long; What's the smallest tank available? Peace! 8)

The hardware store has disposable oxygen cylinders just like the propane.  They sell mini welding/brazing torches that run on propane/oxygen or MAPP/oxygen.

Check it out, they are like $8 or $10 bucks for one tank of O2.  Pretty expensive, but if you only need a little its the way to go.

1 mol

IIRC, those little tanks are about ~1 mol (15g) of oxygen. Might suit your need, although it won't get you away from the need for a gas regulator.
