Anybody in AU selling those mini oxygen regulators for disposable tank

Everything feels like the wrong way when your a lefty. I am one also.

'cept wanking. Then you can close your eyes and pretend it's somebody else's hand

Screwy

Interesting. 30 seconds was enough to hit 13ppm? I suppose it would depend on a few factors though, flow rate, etc ...

Yep they have a left handed thread on them.

So with the Reg in one hand and the bottle in the other hand and below the reg, bottle closest to you, spin the bottle counter clockwise.

You will see arrows at the top of the bottle to show you this.

Be careful that the reg and bottle are plumb so you don't cross the threads and apply pressure when threading on. If the bottle pressure is making this difficult for you to thread on you can open the reg a little to help you. Just don't do it if you don't have. Or be quick so you don't waste too much O2.

So ~4 months after I first started this thread, finally brewed up a batch (~1.060 all-grain) and injected ~30 seconds of pure O2 through a 0.5 micron stainless stone (my normal method is the old "splash and shake"). Pitched a pack of rehydrated US-05.

Holy ****, the thing went mental. With US-05 I've never got more than maybe a centimetre or two of krausen, always a very restrained fermentation. Checked on this pure O2 batch and krausen has filled the entire headspace of my 20L Willow fermenter (about 3 inches of space) and the cling wrap I use to cover the opening has inflated like a friggin balloon about the size of a tennis ball! It's been 3 days since then and the krausen is still high and spry, I was afraid I'd have to install a blow-off tube but it seems to be content to just live in the headspace for the moment. :blink:

If this result is any indication it's obvious my previous "shaking" method was woefully inadequate. I'm actually shocked at the dramatic difference, I knew it would make some difference, and it was certainly much easier than shaking 20kg of wort for extended periods of time, but I wasn't expecting this sort of krausplosion!

TL;DR Have a blow-off tube handy if you're trying pure O2 for the first time.

I had similar results to slash except for when I did it with coopers yeast which Im putting down to the first cultured generation. With another yeast it was licking the lid for about three days. Still conditioning and eagerly awaiting to taste the results.

Killing some time listening to Jamils show and he recommends measuring flow of O2 to ensure consistency.

Are any users using or retailers retailing a flowmeter, maybe like these ?

Would seem fairly cost effective, any comments or recommendations?

 

[slash22000]

Recommended rate is 1 litre per minute. Never thought about using a flowmeter to be honest, I put the airstone in a glass filled with sanitiser, then turn the tap until I can see it's bubbling nicely. Dunno what the flow rate is.

 

[potof4x]

I'll throw this link in to the same unanswered question in another thread involving another retailer marketing a different system.

More gadgets and potential for leaks running a flow meter I know, but I would like to have a better measure short of buying a DO meter.

 

[Black n Tan]

Another gadget...must have it!

I bought the one at the top of the linked page (3L). Works fine. 1L/min seems a bit much though - too many bubbles breaking the surface. I've been doing 1/2 L/min.
I guess once you know what to look for, you could do away with it. I just wanted a benchmark to start from - consistency = repeatability

If you think o2 is a 'gadget' you're an idiot.

Vortex, take a deep breath mate. Yes I do use oxygen, so I feel very fortunate not to meet your definition an idiot. My gadget comment was in response to Poto4x comment about the oxygen flow meter being a gadget (which I just bought BTW). So mate stop reading more into what is said in the post.

Learn to use the quote button then That would have made it clear.

I haven't used my O2 system for a while, I used to weigh the cylinder on the kitchen scales and work out ppm of oxygen in the volume of wort. It's probably a bit more accurate than flow.

 

[stakka82]

I don't have one, but that's a great way to do it.
