Yes! Apeks ,Supercritical, systems use a simple separation technique called fractional ,extraction, that takes full advantage of the varying solvency power of CO 2 at different pressures and temperatures. Unlike competitive systems that utilize complex multi-vessel fractional separation methods, our systems can perform fractional extractions through both subcritical and ,supercritical extraction, modes.
