Iamafutha analyzerigaya into eqinile ngaphambi kokukhipha ukuze kwandiswe indawo yokuxhumana enoketshezi oluqinile. Bese, faka udaba oluqinile esikhwameni sephepha lokuhlunga bese ulufaka ku-extractor. Ingxenye engezansi ye-extractor ixhunywe ku-flask engezansi eyindilinga equkethe i-leaching solvent (i-ether anhydrous noma i-petroleum ether, njll.), futhi i-condenser ye-reflux ixhunywe kuyo.
I-flask eyindilinga-phansi iyashiswa ukuze i-solvent ibile. Umhwamuko ukhuphuka ngepayipi elixhumayo bese ungena ku-condenser. Ngemva kokujiya, idonsela ku-extractor. I-solvent ithinta okuqinile ukuze kukhishwe. Lapho izinga le-solvent ku-extractor lifinyelela endaweni ephakeme kakhulu ye-siphon , I-solvent equkethe i-extract iphindiselwa emuva ku-flask, ngaleyo ndlela ikhiphe ingxenye yento. Khona-ke isincibilikisi se-leaching kufulaski oyindilinga-phansi siyaqhubeka nokuhwamuka, ukujiya, ukuvuza, kanye ne-reflux, futhi siphinda le nqubo, ukuze into eqinile ikhishwe ngokuqhubekayo yi-solvent leaching solvent, futhi indaba ekhishiwe inothiswe ku-flask.
Isizinda se-Liquid-solid sisebenzisa ama-solvents ukufeza inhloso yokukhipha nokuhlukanisa ngokusebenzisa ama-solvents ane-solubility enkulu yezingxenye ezidingekayo kwingxube eqinile kanye ne-solubility encane yokungcola.
I-Siphon: Isakhiwo se-tubular esiphenduke u-U.
Umthelela we-Siphon: I-Siphon yinto ye-hydrodynamic esebenzisa umehluko wezinga loketshezi ukuze ikhiqize amandla, angamunca uketshezi ngaphandle kosizo lwepompo. Ngemuva kokuthi uketshezi endaweni ephakeme lugcwalise i-siphon, uketshezi esitsheni luzoqhubeka nokugeleza endaweni ephansi ngokusebenzisa i-siphon. Ngaphansi kwalesi sakhiwo, umehluko wengcindezi ye-liquid phakathi kwamaphethelo amabili wepayipi ungaphusha uketshezi phezu kwephuzu eliphakeme kakhulu futhi lukhiphe komunye umkhawulo.
Amafutha aluhlaza: Ngemva kokukhishwa kwesampula nge-ether anhydrous noma i-petroleum ether nezinye izincibilikisi, into etholwe ngokukhipha isincibilikisi ibizwa ngokuthi amafutha noma amafutha aluhlaza ekuhlaziyeni ukudla. Ngoba ngaphezu kwamafutha, aqukethe izingulube namafutha ashisayo, ama-wax, ama-resin nezinye izinto.
