Oxygenation setup

[Cliff]

Whats the whole advantages to using this expensive metal wand and metal stone? :

You can make your own wand from plastic or even SST tubing.
The advantages of the wand are (a) you don't have to wrestle the friggin damn coiling poly tubing to the bottom of the pot or fermeter while it's constantly trying to pop back up out of the fluid, (b) it's worlds easier to sanitize and clean, (c) it's not flopping around all over the place while you are deploying it rubbing up against all sorts of surfaces thus defeating your efforts at cleanliness, and (d) it packs away nicer.

All these observations are first hand.

I got my regulator from NB? about 2 years ago and came with a 1/4 barb, 1/4" tubing, and a .5 mircon stone. The regulators i have seen lately are 1/8" barb/hose.

Can anyone with experience of pure oxygen wort injection advise if using a sanitiser on the ID of oxygen tubing is safe. I have both Iodophor & Starsan but have a concern that they might react chemically with the oxygen & cause a crisis situation. I have an inline sanitary filter in the tubing but it, of course, needs to be above the level of the wort so their is still the possibility for infection without sanitation, in my view.

Thanks for any experienced recommendations.

I've never had any ill effects with O2 and Star-San combining.
The Phosphoric acid is pretty dilute. Besides, if it reacted violently with oxygen, they wouldn't use it in Coca Cola, Pepsi, etc.

Slow the drama train. You're fine.

I bought the AHB kit with regulator, tubing, and stone and used the disposable bottles for a while and got tired of the regulator and bottles and went to my local welding/o2/co2 and got a used 5lb tank with used flow meter and regulator for $115.00. I hook up the tubing and stone to the out of the flow meter and can adjust the rate while knowing how much is going into the wort. The bottle will last years I'd imagine.
