Cold separation during Supercritical and Subcritical CO2 Fluid Extractions (SCFE) has been shown to improve retention of THC-A and minimize thermal degradation compared to other systems that apply significant amounts of heat to the separator/collection vessel.
All Apeks Supercritical systems utilize gas pumping which allows the separator to operate at a lower pressure and subsequently at a lower temperature. Yes, pumping gas requires a larger pump compared to pumping liquid, however it is a better option to preserve the precious oils that are being extracted!
