A supercritical extraction equipment with two 5L extraction vessels. High-efficiency extraction: The density of supercritical fluids is close to that of liquids, the viscosity is close to that of gases, and the diffusion coefficient is large, allowing for rapid penetration into the extract, thus improving extraction efficiency. Low-temperature operation: The extraction process is carried out at low temperatures, avoiding damage to heat-sensitive substances caused by high temperatures, making it particularly suitable for the biological, pharmaceutical, and food industries. No solvent residue: Supercritical fluids have good solubility near the critical point, and the solvent and extract can be separated by changing the pressure and temperature during the separation process, leaving no solvent residue. Recyclable: Supercritical fluids (such as CO₂) can be recovered and reused after use through methods such as depressurization and cooling, reducing costs.

1 Extraction vessel: Double extraction vessel design, single vessel volume 5L, total volume 10L, can be used independently or in combination.
2. Separation vessel: Usually equipped with a 2L and a 1L set, working pressure 30MPa, supporting multi-stage separation to improve the purity of the extract.
3. Working pressure: Up to 50MPa (500bar), supporting dynamic pressure adjustment, pressure control accuracy ±0.1MPa.
4. Working temperature: Room temperature ~85℃, temperature control accuracy ±1℃, precise temperature control is achieved through a water jacket circulation heating system.
