Apeks Supercritical’s engineers completed an amazing CO2 extraction on Kava Kava. Using the 1500-5L system (5-liter extraction vessel), Apeks extracted roughly 200 grams of highly concentrated Kava Kava oil in just over 2 hours. Testing is proceeding to determine how much can be extracted without changing out the raw material.
The following video link (Kava Kava Oil) shows the efficiency of the Apeks cyclonic separation chamber. Note the clean upper vessel walls and no dry ice formation. Look closely and you can see the CO2 evolving from the oil in the bottom in the form of carbonation.
