Use this 2 micron stone with an oxygen source or an aeration pump to provide your yeast with oxygen pre-fermentation, or with CO2 to speed up carbonation of the finished beer.

Please Note:
Do not touch the stone with your bare naked fingers! The oils in your skin will clog the tiny pores. Please handle with gloves.

The barb fits 1/4" (6.35mm) ID tubing.

Stainless steel stone.
