The SFE is versatile "multi-solvent" extraction equipment with precise control of process parameters for analytical purposes :
|CO2 pump||Variable flow rate from 0 to 100 g/min.
Variable pressure from 0 to 1000 bar.
|Extration vessel||50 / 100 / 200 / 500 ml.|
|Oven||Used to heat the extration vessel.|
|Separator||For extract separation / collection of extracts and CO2 recycling.|
|Pressure Control||Back pressure regulator to control the pressure.|
|Control board||Display and record process value.|
|Co-solvent pump||Flow rate up to 24 ml/min and pressure at 400 bar.|
|Filter||Absorbent bed cartridge in the recycling loop to trap lightest and volatile particules.|
|Stirrer||Supply of a magnetic stirrer installed on the extractor at 350 or 700 bar.|
|Automation||Data acquisition and recording process value on PC.
Additional control with automated valve, to be discussed.
|Spare vessel||Supply of additional spare vessel.|
|Sampling loop||Pressurized sampling loop for collecting extract in a precise volume allowing to make on line sample analysis.|
|Column||Liquid fractionation column module.|
SFE with Co-Solvent pump and stirrer
|Sapphire||Windows on the extraction cell for visualization (consult Extratex to define the conditions).|
|Spectroscopy||On-line spectroscopy cell to be placed at the exit of the extractor.|
