This supercritical extraction system is specially designed for research on supercritical water and CO₂, enabling efficient extraction of natural compounds. With a CO₂ recycling system, PID temperature control, and automatic pressure regulation, it ensures precise and stable extraction. All surfaces in contact with food are made of stainless steel, preventing microbial attachment. Additionally, users can flexibly load samples and add trapping solutions such as water or alcohol to optimize performance.
