    Are the O2 bottles disposable? Just comparing it to this deal.

    do you think a 0.5 micron stone might create finer bubbles and aid in better absorption of the o2 into solution ?

    I note on the Tesuco website:

    Part#GTCD22 Disposable Gas Bottle 100% Food Grade CO2 2.2 Litres Grey Cylinder.
    "The 2 litre disposable gas cylinders have a much larger capacity and are filled to a much higher pressure than conventional disposable cylinders currently available."

    I think 2 micron is typically used for cleaning reasons, at least thats the impression I get from morebeers website.

    0.5 micron for oxygen, 2 micron for air.

    Malted, the name suggests that the bottle you're talking about is for Co2?

    It was a copy and paste from the Tesuco disposable gas cylinders webpage.
    Yes the bottle appears to be carbon dioxide but one would need to confirm with Tesuco what sized reg would be needed for it as it may not be the one in the OP.


    micblair did some good research. :super:

    yep, the pressure from an aquarium pump may not be enough to get through the fine pores of the 0.5 micron, but the pressure from an o2 cylinder will

    From memory, according to JP/JZ's "Oxygenation" TBN Podcast the size of the stone does not matter, and you can simply bubble it in without any stone at all for the same result.
    The reason for this (they said) is that the surface area of the quickly rising bubbles is minimal compared the surface available at the at the wort/Air(Oxygen) surface. What is important is saturating the head-space inside the fermentor with O2 and then it will absorb into the wort from there.

    That's the same rule for aquariums with air pumps

    Yeah, I think the analogy came up because JZ used to keep fish, or something.

    I remember the way it was explained to me at the Perth Chiclid Society many years ago. If there was a lot of absorbing of the air in the water then the bubble would not reach the surface. It is actually the breaking of the surface tension on top of the tank which has a greater surface area that does the main job.

    Sorry, regulator part number apparently is OTS200RO not OCS200RO

    An old post, but found that these oxyturbo bottles are available locally in the Huon Valley (Tas) for those interested - @ Mitre10. Also the regulator OTS200RO is available from Reece Plumbing at Kingston. A bit pricey at $65 for the bottle, but a local supplier is convenient. The regulator was priced this morning at $78.
