Anyone know the safety of using the disposable oxygen tanks you get from the hardware store? It's not medical grade, but the cheap regulators you can get on home brew websites recommend their use.
I've been keeping mine too wondering what to do with them.
They are steel, so they are recyclable. If your city doesn't take the metal, there will be a metal recycler somewhere who will. Don't expect much cash but it's better than the landfill.
If you are asking if they are ok for aerating wort, there are small sanitary filters that you use inline to prevent anything nasty from getting into your beer.
I've read a lot about medical vs welding grade o2 and it's basically the same.
Check with your town recycling center. Mine allows drop offs of all kinds of stuff and they definitely have a section for pressure tanks. That's where I scored a free O2 regulator ;-) gloat.
Never seen these. Any pics? I just shake to aerate my wort, but these things might be useful for some other purpose some day. I assumed you had to get O2 from a medical supply shop.
Another good beer related use for oxygen is hangover relief. I had a smoothie shake that was infused w. oxygen from a bottle with a straw (like wd40) and it took me from a crushing hangover to one where I could function. I'm sure with our homebrew ingenuity we could do a better jog of oxygenating than a straw, although I would not want to put a stainless stone in a shake. Also good for altitude sickness.
Remember, you should be seeing very few bubbles on the surface when adding O2 to the wort. Any bubbles on the surface is wasted O2; the O2 should just BARELY be leaving the tank. You should be able to get at least ten or twelve batches per bottle, I'm probably a bit less than that but I'm also one who isn't as careful about not wasting O2!
Nope it's not a misprint.
You get a whopping 1.4 Ounces of O2 in that bad boy.
I use the aeration wand from Williams Brewing, which is 2 micron. They CLAIM 20-30 batches per O2 bottle, I'm nowhere near that (which means I'm doing something wrong!)

I'm with you there. I think the 1/2 micron would do a better job of breaking up the o2 into smaller bubbles.
I'm guilty of cranking mine open to look like its got a raging full boil. ~30 sec. I'm prolly just wasting o2.
On the .5 micron did you happen to have a pressure reading on the line to the stone to create the stone covered in bubbles?
I have been using a Holley carburetor fuel inlet (bronze crushed bead unit) that I had new spares that seems to work as a cheap and fast stone. I know a 2.5 or a .5 stone should be used this is why i'm asking about the pressure required to create the bubbles.
As far as O2 being wasted i've used the 260 cu/ft welding bottle for years so the volume used and extra wasted isn't a factor.
The best use of a Home Depot disposable bottle so far was to drill out the neck to allow filling with old reloading powder with a detonator cap added. We used a ships auger the same diameter as the bottle and placed the bottle into the hole in the center of a 4' diameter dead oak tree at the ranch. Big Boom!!!!!!!! tree be gone. That has been the best use of a disposable bottle unless I mention the one about a full one thrown into the burning fire pit. It went BOOM!!! also.
Yes. They do it at Lowe's...you can do it, too.Is it safe to store these canisters indoors when not in use?
I would double check that the regulator/valve connection to the tank doesn't leak. People have reported losing the content between brew sessions, due to a poor/leaky valve connection. Some resort to removing the regulator/valve from the tank during storage. That will prevent any leaking to occur.Is it safe to store these canisters indoors when not in use?
Oh, yeah. Definitely unscrew the regulator. You'll lose a bit with the pop as the tank's internal valve seats, but it beats letting it all out over time.I would double check that the regulator/valve connection to the tank doesn't leak.
