Carb Stone - 0.5 micron
Stainless steel 0.5 micron diffusion stone is useful for oxygenating wort with pressurized gas or force carbonation. Barbed fitting, fits 1/4" I.D. tubing.
Love this size as compared to others (e.g., 2 micron) as it gets the CO2 into solution much quicker with the fine-sized bubbles
This is an excellent product. When carbinating beer, in my experience, it has got the job done in half the time in my corny kegs versus the standard top gas entry. I sterilize it in a shot glass of whiskey by using a measuring syringe (like you get from CVS for kids medicine) to force the sterilizing solution through the stone.
Great for oxygenating your wort. Easy to sanitize. Not much else that needs to be said but it requires me to use at least 50 characters.
No complaints. The stone helped oxygenate my beer.
Works great and doesn't plug up if you rinse it after use. I store mine in rubbing alcohol and then use gloves when rinsing prior to use. Not long after purchasing, the stone started popping off the metal barb. I was still able to use it until this last batch where the air pushed it off the barb and it had to sit in my primary through the fermentation. Then I forgot about it and it got eaten by my garbage disposal when I dumped the trube. I just ordered my second one, so hopefully the stone stays on the metal barb a little longer. Overall I would recommend this.
