Diffusion Stone .5 Micron, 1/4" barb

This .5 micron stone is ideal to forcecarbonate your kegged beer, or as an aeration stone prior to fermentation. Thebarb is 1/4" ID.

To Use: Attach 2 feet of 1/4" tubing from the "gas in" dip tubeinside the keg. (Tubing not included). You set your desired pressure on theregulator and gas gets emitted through the .5 micron stainless stone. Thebubbles rise through the beer creating so much surface area contact between gasand liquid that the absorption rate is very rapid. This is very similar to howbeer is carbonated in breweries.

Do not touch the stone with your bare hands. The oils on your hands can clogthe small pores. If you do clog the pores simply boil the stone to remove theoils. To clean and sanitize, just boil the stone.
