SFE-4000

Supercritical Fluid Extraction employs a supercritical fluid, most commonly CO2, as the A mobile phase solvent for the extraction. The intrinsic low viscosity and high diffusivity of supercritical CO2 has rendered SFE a faster extraction and higher efficiency technique when compared to traditional liquid extraction. This provides faster flow rates and thus faster extraction times without the requirement for a higher pressure system.

The addition of a co-solvent to the CO2 flow can help tune the strength further. The extraction oven can offer temperatures up to 100°C. Lastly after the extraction vessel is the back pressure regulator, which provides the back pressure requirement to keep the CO2 supercritical, and is an integral part of the performance of the extraction.

System Features

Advantages

Analytical SFE

The analytical CO2 pump offers built-in peltier cooling to maintain a stable CO2 flow yielding excellent extraction time reproducibility. Automatic, built-in shut-off valves close the CO2 inlet and outlet and isolate the pumps for quick and simple priming when not pumping.

The system can be configured for CO2 only or 1-10 co-solvents, 1-10 extraction vessels for the vessel volumes listed above and 1, 6, 12 or 54 fractions.

Hybrid SFE

The hybrid CO2 pump offers a flow range from 0.5 to 20mL/min covering both analytical 10mL vessels up to semi-prep 100mL vessels. Automatic, built-in shut-off valves close the CO2 inlet and outlet and isolate the pumps for quick and simple priming when not pumping.

The system can be configured for CO2 only or 1-10 co-solvents, 1-10 extraction vessels for the vessel volumes listed above and 1, 6, 12 or 54 fractions.

Semi-Preparative SFE

The semi-prep CO2 pump offers a flow range from 3 to 50mL/min covering 50mL vessels up to 200mL vessels. Automatic, built-in shut-off valves close the CO2 inlet and outlet and isolate the pumps for quick and simple priming when not pumping.

The system can be configured for CO2 only or 1-10 co-solvents, 1-10 extraction vessels for the vessel volumes listed above and 1, 6, 12 or 54 fractions.

Preparative SFE

The Prep CO2 pump offers a flow range from 5 to 150mL/min covering 500mL vessels up to 2L vessels. Automatic, built-in shut-off valves close the CO2 inlet and outlet and isolate the pumps for quick and simple priming when not pumping.

The system can be configured for CO2 only or 1-10 co-solvents, 1-10 extraction vessels for the vessel volumes listed above and 1, 6, 12 or 54 fractions.
