The invention features a device (100) for extracting organic compounds from a sample, coupled with a receptacle (1) containing a solvent and subjected to microwave heating. An elongated means bears at one end engaged in the receptacle (1) a cartridge (120) containing the sample to be treated, a cylindrical wall (130) encloses the said elongated means that emerges from the receptacle (1) such that a ring-shaped steam passage (131) is defined between them, and opens in sealed manner into the receptacle (1). A solvent reservoir (140) comprises an upper aperture (141) for fitting a refrigerating system or a closed hood. A connecting conduit (150) extends from the reservoir (140) along an inclined direction (Y), towards the said means into the ring-shaped steam passage (131) and comes in contact with the said means.
L'invention concerne un dispositif (100) d'extraction, de composés organiques d'un échantillon, couplé à un récipient (1) contenant un solvant et soumis à un chauffage micro-ondes. Selon l'invention, un organe de forme allongée porte à une extrémité engagée dans le récipient (1) une cartouche (120) renfermant l'échantillon à traiter, une paroi cylindrique (130) entoure ledit organe allongé qui émerge du récipient (1) de sorte qu'un passage annulaire de vapeur (131) est délimité entre eux, et débouche de manière étanche dans le récipient (1), un réservoir (140) à solvant comporte une ouverture supérieure (141) pour la mise en place d'un système réfrigérant ou d'une hotte aspirante, un conduit de raccordement (150) s'étend à partir du réservoir (140) suivant une direction (Y) inclinée, vers ledit organe pour déboucher dans ledit passage annulaire de vapeur (131) et venir au contact dudit organe.
