Oxywand w/ .5 Micron Stone
That is not the only reason yeast love the OxyWand". Yeast hate to compete with bacteria and you hate to drink them. Sintered stainless stones are made of tightly compressed stainless steel powder to create a porous block through which oxygen can flow. This micro maze is also the perfect environment for bacteria to live in after the stone has been used once in wort. That is why we love to boil our stones prior to use. The stone on the OxyWand" is connected via a 1/4" flare fitting and can easily be removed and cleaned after use and then boiled before your next brew day.
The assembly is 26" long and will easily reach the bottom of glass carboys, dropped into stainless conicals, Speidel fermenters, etc. The 0.5 micron size stone is designed specifically for use with compressed oxygen tanks. You will want to use 1/4" tubing. See the recommended regulator to connect to disposable style compressed oxygen cylinders available from your local hardware store.
The advantage of using compressed oxygen to oxygenate is speed - you can oxygenate your wort in 60 seconds as opposed to 5 minutes with aeration. This .5 micron stone can only be used with compressed oxygen because an aeration pump does not supply enough pressure.
