Infinity Supercritical 10L CO2 Extractor: Supercritical CO2 Hemp Oil Extraction for Full Spectrum Botanical Oil which retains the terpenes and other valuable plant components during extraction. System runs silent with small footprint of 24 inches by 48 inches... More Info

Infinity Supercritical has developed the most profitable Supercritical CO2 Extraction Machines. Our CO2 terpene extraction system rapidly produces shelf-ready oils which make more money. Perfect for hemp oil extraction using environmentally friendly CO2 extraction equipment. Manufactures efficient oil extraction systems and machines for natural terpenes, flavorings, fragrance, hemp, beer hops, lavender and other botanicals. New for 2021 includes Molecular Hydrogen Skin Cream Machine for production of high value cosmetic skin cream. Silent technology includes supercritical co2, oil-to-oil extraction using induction magnetic mixing, and eco friendly hydrodynamic cavitation water as the solvent in our closed-looped systems. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. SCO2 can remove water from wood as an alternative to conventional kiln drying.
