Diffusion Stone – 0.5 Micron with Flare Threads

Our .5 micron carb stone is ideal to force carbonate your kegged beer, or as an aeration stone prior to fermentation.

To properly sanitize your stones, we recommend boiling the stone for 1-3 minutes to help break down anything within it and kill any bacteria that might be present. Running some air through the stone during the last minute of the boil can help drive out any broken-down impurities.

If boiling is not an option, we recommend soaking in Star San, which will remove a majority of surface contamination/bacteria, but will not sanitize the interior of the stone which may or may not be contaminated. For best results, push air thought the stone while it’s in the sanitizer solution for 5 minutes.

Please note that it’s best not to touch the actual sintered portion of the stone with your hands. The oils on your fingers can clog the small pores in the stone. Handle the stone by the barb or any attached tubing, or place it in a baggie or some foil to keep a barrier between the stone and your fingers.
