0.5 2.0 micron SS stainless steel beer oxygen air aeration carbonation stone with 3/16″ 1/4″ 3/8″wand Barb 1/2″ NPT Thread for home brewing

The 2-micron beer oxygen stone is typically used for oxygenation applications and the 0.5-micron air stone uniform distribution of tiny bubbles for carbonation applications.

◆   HENGKO diffusion stone is suitable for force carbonation of beer, it is ideal to force carbonate the kegged beer, or as an aeration stone prior to fermentation. Carbonate the beer just like the pros with this stainless steel carbonating stone. 0.5 HENGKO oxygen stone is used to force carbonate beverages like beer, champagne, or sparking meads with carbon dioxide. compared with the 2.0 micron stone, the 0.5 micron stone will carbonate beer quicker and with a long-lasting head because the bubbles that it creates are smaller. It quickly carbonates beer/soda water, and the CO2 or O2 will be forced through the millions of tiny pores in the stone, which dissolves the gas into the liquid. Let your beer or soda water get a good mouthfeel.

◆   HENGKO SS air stone is commonly used to aerate the wort before fermentation, which helps ensure a healthy start to the fermentation process. The HENGKO 2.0 micron oxygen stone can be used to oxygenate wort using an oxygen regulator. The holes in the 0.5 stone are too fine to use to aerate the wort with an aeration pump. The 2-micron HENGKO inline carbonation stone has millions of tiny pores so that this diffusion stone will quickly oxygenate wort & carbonate beer/soda prior to fermentation, to lower fermentation times & not easily get clogged. Different micron stones produce very small bubbles, which are ideal for efficient absorption of the gas into your wort. The most common use for this specific stone is to build an inline oxygenation assembly where the stone is threaded into a 1/2" NPT TEE, so chilled wort passes the stone on the way to the fermenter. It's important to limit the flow of oxygen in this setup to avoid over-saturating the wort.

◆   For purging wine with nitrogen or argon to eliminate dissolved CO2 or for macro-oxygenating with oxygen.

Improve the health of yeast:   Insert the oxygenation wand into the fermenter and pump in thousands of microscopic oxygen bubbles for 1-2 minutes, the yeast will be more healthy and produce amazing flavors, have the stamina to completely finish fermentation. Yeast hates to compete with bacteria and you hate to drink bacteria too. HENGKO oxy wands are made of a healthy food-grade micropore micro maze body part in which oxygen can flow, dispersing plenty of microbubbles, it’s also the perfect environment for bacteria to live in after the stone has been used once in the wort. The oxy wands are made of 16 “, 26 “, and 36 “ wand parts for different sizes glass carboys, that will easily reach the bottom, reach into various stainless conicals, Speidel fermenters, etc. They supply OD 3/16 “, 1/4 “, 3/8 “ tubing size for choose.  The 0.5-micron size stone is designed specifically for use with compressed oxygen tanks. The advantage of using compressed oxygen to oxygenate is speed - you can oxygenate your wort in 60 seconds as opposed to 5 minutes with aeration. The 2-micron size stone works well with both compressed oxygen and aeration pumps. The advantage of using compressed oxygen to oxygenate is speed - you can oxygenate your wort in 60 seconds as opposed to 30-120 minutes with aeration. The advantage of using a pump for aeration is cost - you never have to buy compressed oxygen cylinders.  

By the way, the diffusion stone is also used in the aquaculture industry, for example in nursery ponds, soilless cultivation of plants, and even with pumps for aquariums.
