Supercritical CO2 Extraction Machine 1L Model

A 1-litre supercritical CO₂ extraction machine is a compact, high-pressure system used primarily in laboratories or small-scale production for extracting essential oils, active compounds, or flavors from plant materials. Operating typically at pressures up to 40–50 MPa and temperatures up to 85°C, this equipment uses CO₂ in its supercritical state as a solvent, allowing efficient and selective extraction without leaving solvent residues. The machine usually includes one or more extraction vessels, separator vessels, CO₂ and co-solvent pumps, and temperature/pressure control systems. Materials like stainless steel (SS304 or SS316) are used to ensure durability and resistance to corrosion. Some models allow co-solvent addition to enhance the extraction of polar compounds. These systems are equipped with safety features such as pressure relief valves, gauges, and automated control panels. Though limited in volume, the 1L model is ideal for research and development, formulation testing, or niche high-value product extraction. Brands like CAREDDI, Biogreenness, and Wanda Machinery offer well-known models in this category, often with customizable features based on application requirements.
