Supercritical Fluid Extraction

The Spe-edTM SFE Basic is the base SFE in our series of instruments for supercritical fluid processes.
The straightforward design of the Spe-ed SFE Basic includes the essential components required for supercritical fluid processes. This instrument is robust enough for rigorous use in the research lab, with a price tag that allows everyone to take advantage of the benefits of Supercritical fluids. It is safe, simple to operate, fast and affordable, with features found in other, more expensive SFE systems.

Supercritical Fluids excel in emerging industries like foods, natural products and nanotechnology where solvents can’t be used.

The system features:

• temperatures to 150°C

• pressure up to 10,000 psi (690 BAR)

• pump flow rates up to 200mL/min*

• control of flow rates to pressure vessel

• fully-adjustable, non-clogging micro-metering valve

• process vessels ranging in size from 5 to 100mL

• extract collected into SPE cartridges or standard glassware

• in-line trapping capabilities

• modifier addition capability

• liquid sample extraction capability

• multiple over-pressure safety devices
