Using oxygen for brewing

[masterbrewer2]

Yes, but realize you'd only be using the 2 lowest flow rate settings: 0.5 and 1.0 l/m, which may be all you'd need anyway.

Thanks I'll look around for a lower flow rate

Another good point for a proper tank outside of knowing your flow rate, a Lowe's employee told me a lot of folks buy, use and return the red tanks. The weight differential is tough to notice so many times, the empty tanks go back on the shelf. So be careful if you are buying these.

Isn't there a seal on the nozzle, such as on small propane/butane canisters?

But yeah... retail is weird.

Heads-up, there's another current thread with a similar topic:

I picked up a 40cf (I think) used tank at a local gas supply place then bought a cheap regulator on Amazon. This should last 10 years on a tank. make sure to get some inline hepa filters. And shut off the gas supply at the tank after each use.

I did those disposable tanks for a while but they never lasted. Either they leaked or were never full to begin with.

I really didn’t think about buying a full medical oxygen and just treating it as disposable.

On mine was a slip-on plastic cap like a propane cylinder. More like a dust cap & thread protector, not something that positively indicates the cyl. has been used/connected.

Frankly, whenever posts like this come up, I'm a bit puzzled at how quickly folks are going through O2. I tend to brew two batches a month and a canister of hardware store O2 will last me at least two, more frequently three years. I know this because I write the date on each canister I buy.

Considering those setups typically don't have flowmeters it's not surprising it would be quite easy to use a lot more than may be necessary.

You won't need those when using (pure) O2 from a cylinder. Only when using air, such as with an aquarium pump.

Not at all helpful but I just use dry yeast and don't worry about it.

Have you looked at welding suppliers?

Same. For years I thought liquid yeast was the big reason my beers tasted great (good fermentation). Nope. I've been using dry yeast the past 2 years and haven't looked back. So much easier as well. Especially if you're a new brewer. Dry Voss Kveik should be recommended for all Newbie starter kits. Not worrying about temperature is huge for beginners

Look out for second hand oxygen concentrator as an option as well.
Works great.

I have a 5# (I think?) medical O2 tank that I bought several years ago on Craigslist. I know I’m gonna have to buy something else at some point, but I think it’s been about 8 years since I bought it. Something larger will definitely last me almost forever.
