I-centrifuge isebenza kanjani ukuhlukanisa igazi

I-centrifuge iyithuluzi elibalulekile lelebhu elisetshenziswa kabanzi emikhakheni eminingi yesayensi neyezokwelapha. Enye yezindlela zayo eziyinhloko iwukuhlukanisa izingxenye zegazi ngezinjongo zokuxilonga nokucwaninga. Kulesi sihloko, sizohlola ukuthi i-centrifuge isebenza kanjani ukuhlukanisa igazi kanye nezici ezahlukahlukene ezifaka isandla ekusebenzeni kwalo kahle.

Ukuqonda Ukwakheka Kwegazi

Ngaphambi kokuhlola indlela esebenza ngayo i-centrifuge, kubalulekile ukuqonda ukwakheka kwegazi. Igazi ngokuyinhloko lakhiwa amangqamuzana abomvu egazi (ama-erythrocyte), amangqamuzana amhlophe egazi (ama-leukocyte), ama-platelet (ama-thrombocyte), kanye ne-plasma. Ingxenye ngayinye idlala indima ehlukile ekugcineni impilo yomzimba iyonke.

1. Inhloso Yokuhlukaniswa Kwegazi

Ukuhlukaniswa kwegazi kubalulekile ezinqubweni eziningi zezokwelapha kanye nophenyo lwelabhorethri. Ngokuhlukanisa izingxenye ezithile zegazi, abacwaningi kanye nochwepheshe bezempilo bangathola ukuqonda okubalulekile ngezifo, benze izivivinyo zokuxilonga, futhi bathuthukise ukwelashwa okusha. Ngaphezu kwalokho, ukuhlukaniswa kwegazi kuvumela ukuqoqwa kwezingxenye ezifana ne-plasma noma ama-platelet, ezingasetshenziswa ngezinjongo ezahlukene zokwelapha.

Isimiso Sokusebenza Se-Centrifuge

Amandla e-Centrifugal ayisisekelo sokusebenza kwe-centrifuge. La mandla asebenza ngaphandle esuka enkabeni yokujikeleza futhi abangela ukuthi izinhlayiya ezixineneyo kusampula zithuthele emngceleni kuyilapho izinhlayiya ezilula zihamba ziye enkabeni. Lesi simiso senza kube nokuhlukaniswa kwezingxenye zegazi ngokusekelwe ekubuneni kwazo okuhlukahlukene.

2. Amandla E-Centrifugal: Ukusheshisa Kwe-Centripetal kanye Ne-Centrifugal

Amandla e-Centrifugal avame ukubhekwa ngephutha njengamandla angempela. Eqinisweni, avela ekusheshiseni kwe-centripetal, okuyi-force-directed inward induced industry motion (isb., ukuzungeza kwe-centrifuge rotor). Ukusheshiswa kwe-Centrifugal kungamandla-mbumbulu atholwa yizinhlayiya ngaphakathi kohlelo olujikelezayo ezisunduzela ngaphandle. Ngokulinganisa la mandla amabili, i-centrifuge ikhiqiza ukuhlukaniswa okudingekayo.

Izinhlobo ze-Centrifuges

Kunezinhlobo eziningana zama-centrifuge ezitholakalayo, okuhlanganisa ama-microcentrifuge, ama-benchtop centrifuge, ama-centrifuge anesivinini esikhulu, kanye nama-ultracentrifuge. Uhlobo ngalunye luyahlukahluka ngokuya ngesivinini sokujikeleza, umthamo, kanye nokusetshenziswa. Ama-ultracentrifuge, akwazi ukufinyelela isivinini esimangalisayo, awusizo kakhulu ekuhlukaniseni igazi ngenxa yekhono lawo lokuhlukanisa ngisho nezinhlayiya ezincane kakhulu ngempumelelo.

3. Ijubane Nesikhathi Sokujikeleza: Izici Ezithinta Ukuhlukaniswa Kwegazi

Ijubane lokujikeleza kanye nesikhathi kuyimingcele ebalulekile ethinta kakhulu ukusebenza kahle kokuhlukaniswa kwegazi ku-centrifuge. Ijubane lokujikeleza eliphakeme lifaka isampula emandleni amakhulu e-centrifugal kanye ne-centrifugal, okuthuthukisa inqubo yokuhlukanisa. Kodwa-ke, ijubane eliphezulu kakhulu lingalimaza izingxenye ezibuthakathaka, okwenza ukulungiswa kube yinto ebalulekile. Isikhathi esinye isici esibalulekile, njengoba sivumela ukuhlukaniswa okwanele ukuba kwenzeke, ikakhulukazi lapho kuhileleke izingxenyana ezixineneyo, njengamaseli abomvu egazi.

Izinhlobo ze-Centrifuge Rotor

Ama-rotor e-Centrifuge abamba amashubhu esampula ngenkathi ejikeleza ngaphakathi kwe-centrifuge. Ukukhetha uhlobo lwe-rotor kuncike ezidingweni ezithile zomsebenzi wokuhlukanisa igazi. Ama-rotor e-angle eqondile abeka amashubhu e-engile eqondile ngesikhathi sokujikeleza, kuyilapho ama-rotor e-swinging-bucket ehambisa amashubhu angene futhi aphume ensimini ye-centrifugal njengoba ejikeleza.

4. Ukukhethwa kweRotor: Ukwandisa Ukusebenza Kokuhlukanisa Igazi

Ukukhetha ama-rotor kubalulekile ekufinyeleleni imiphumela emihle yokuhlukaniswa kwegazi. Ama-rotor ane-angle eqinile avame ukusetshenziswa ngezinjongo ezijwayelekile, kuyilapho ama-rotor ane-swinging-bucket ekhethwa ekuhlukanisweni okuthambile, njengoba enciphisa ingozi yokulimaza izingxenye ezibuthakathaka. Ukukhetha okulungile kuqinisekisa ukuthi izingxenyana zegazi ezifunwayo zihlala zihlukene, okuvumela ukuhlaziywa okunembile kanye nokusetshenziswa okusebenzayo okuphansi.

Izinselele Nezinyathelo Zokuqapha Ekuhlukaniseni Igazi

Nakuba i-centrifugation iyindlela enamandla yokuhlukanisa igazi, izinselele ezithile kanye nezinyathelo zokuphepha kufanele zicatshangelwe ukuze kutholakale imiphumela ethembekile. Okokuqala, usayizi weshubhu ofanele kanye nokukhethwa kohlobo kubalulekile ukuze kugwenywe ukuvuza kwesampula, ukungcola okuwelanayo, kanye nokuhlukaniswa okungalungile. Okwesibili, ukugcina ibhalansi efanele ku-centrifuge rotor kubalulekile ukunciphisa ukudlidliza nokuvimbela ukulimala kwe-rotor.

5. Izinyathelo Zokuqapha: Izinqubo Zokushisa Nokushisa

Ukulawulwa kwezinga lokushisa ngesikhathi senqubo ye-centrifugation kubalulekile ekulondolozeni ubuqotho bezingxenye zegazi. Izinga lokushisa eliphakeme kakhulu linganciphisa amaprotheni futhi lithinte ikhwalithi iyonke yezingxenyana ezihlukanisiwe. Ngaphezu kwalokho, ukulandela izinqubo ze-centrifugation eziqinisekisiwe eziqondene nezinqubo zokuhlukanisa igazi kubalulekile ukuze kutholakale imiphumela ehambisanayo futhi kuqinisekiswe ukuphindaphindwa kokuhlolwa noma ukuhlolwa kwemitholampilo.

Ekuphetheni, ukuqonda ukuthi i-centrifuge isebenza kanjani ukuhlukanisa igazi kubalulekile ekwenzeni izivivinyo zokuxilonga ezinembile, ucwaningo, kanye nezinqubo zokwelapha. Ngokusebenzisa izimiso zamandla e-centripetal kanye ne-centrifugal, kanye nokukhethwa okufanele kwe-rotor kanye nezinqubo ezicophelelayo, i-centrifugation yenza ososayensi kanye nochwepheshe bezokwelapha bakwazi ukusebenzisa amandla amakhulu ezingxenye zegazi emikhakheni yabo.
