Better Than Shaking a Keg!

Are you tired of carbonating your beer the unpredictable way? 
You crank up the PSI in the keg, shake, and wait with bated breath, hoping you didn’t just over-carbonate your batch. 
Using a diffusion stone pays off with a reliable level of carbonation every time.Our .5 micron stone is ideal to force carbonate your kegged beer, or as an aeration stone prior to fermentation. 
It produces nice small bubbles, giving more surface area for diffusion.

0.5 micron stone
316 Stainless
1/2" diameter. Stone is 1" in length. Overall length is 1 7/8"
The barb is 1/4" OD

How to Use the Diffusion Stone
*The “Stone” sits inside the keg near the bottom.
*A hose barb attaches it to a length of tubing (generally about 2 feet of 1/4” ID thick wall vinyl hose) which is affixed to the short downtube under the “in” or “gas side” post.
*When the CO2 is connected, it sends a tremendous number of gas bubbles out through the beer. The miniscule bubbles create a huge amount of surface area to help absorb CO2 rapidly into the beer. This is actually a miniature version of a device used by commercial breweries everywhere.
*Carbonation should be virtually instantaneous, though the manufacturer recommends carbonating your beer at least a few hours before serving.

To Use: 
Attach 2 feet of 1/4" tubing to the stone and the "gas in" dip tube inside the keg. (Tubing not included). Set your desired pressure on the regulator and gas gets emitted through the .5 micron stainless stone. The bubbles rise through the beer creating so much surface area contact between gas and liquid that the absorption rate is very rapid. This is very similar to how beer is carbonated in breweries.

Cleaning & Sanitizing: It is important to know the oils from your skin can clog the small pores in the stone. We that you attach the tubing to the stone, then hold the assembly by the tubing while subm

【Wort Aeration / Oxygenation】Carbonation stones are a fantastic tool to aerate wort. Keeping yeast at optimum health is acheived when the oxygen-deprived wort is aerated following the knock down process. This helps the yeast not only reproduce efficiently, but also maintain a healthy cell wall that is more tolerant to higher alcohol contents. This allows for several generations of yeast, and more importantly, can reduce fermentation time substantially resulting in faster batch turnover.
【The MRbrew carbonating stones ensure uniform carbonation of beer in storage tanks】 The uniform porosity of carbonating stones produces extremely fine dispersion of CO2 gas and uniform gas flow directly into the tank for optimal speed of solution. Introduction of minutely divided gas into the bottom of the tank causes an active circulation or rollover, which eliminates stratification of gas content and aids removal of dissolved air inadvertently introduced into the beer during processing.
【The 0.5 micron stone is best】 - The bubbles are 1/64th of the volume and there is relatively 4x more surface area than the 2 micron stones, so the CO2 enters solution quicker. The stones are easily removed for flushing and cleaning.
【CARBONATION STONE In-line】 0.5 Microns Carbonate your beer just like the pros with this Carbonating Stone. Affix to a long dip tube installed on the gas side of the Cornelius keg. Set your regulator to about 14 psi, and the gas will be forced through the millions of tiny pores in the stone, which dissolves the gas into the liquid. Your beer will be carbonated overnight.
