At our facilities, we build subcritical extraction equipment that bridges the gap between traditional methods and supercritical complexity. Our subcritical fluid extraction machine leverage gentle, liquid-phase solvents below their critical point to deliver superior yields of heat-sensitive compounds, all while operating at manageable pressures.

Why Choose Our GK Series Subcritical Fluid Extraction?
- True Gentle Extraction: We keep solvents subcritical – liquid and effective, not supercritical. This means lower pressures (<1 MPa vs. >7 MPa for SFE), lower temperatures (<40°C), and perfect preservation of delicate actives like terpenes, pigments, vitamins, and fragile lipids. Say goodbye to thermal degradation.
- Unmatched Solvent Flexibility: Whether you need the strong lipophilic affinity of butane/propane, the mid-polarity of DME, the safety of R134a, or the unique properties of subcritical water/ammonia – our SUS304 systems handle them safely and efficiently. Optimize your process, not your solvent.
- Built for Safety & Longevity: We don't compromise. Military-grade safety systems (pressure relief, gas detection, emergency cutoffs, nitrogen purging) are integral. Full SUS304 construction ensures corrosion resistance and decades of reliable service under demanding conditions.
- Engineered Efficiency: Our integrated multi-stage separation and >98% solvent recovery systems dramatically cut operational costs. High-efficiency condensers and pumps minimize energy use while maximizing throughput.
- Simplified Operation: Automatic PLC controls manage pressure, temperature, cycles, and solvent flow precisely. Focus on your product, not the dials. Consistent results batch after batch.
