okuchaza ukuthi i-centrifuge ihlukanisa kanjani ingxube

Isingeniso ku-Centrifugation: Indlela i-Centrifuge ehlukanisa ngayo izingxube

I-Centrifugation iyindlela yelabhorethri esetshenziswa kabanzi esebenzisa izimiso ze-sedimentation kanye ne-centrifugal force ukuhlukanisa izingxube ngokusekelwe ekubuneni kwazo. Le nqubo ibalulekile emikhakheni eminingana yesayensi neyezokwelapha lapho kudingeka khona ukuhlukaniswa kwezingxenye ezahlukene ngaphakathi kwesampula ukuze kuhlaziywe, kuhlanzwe, noma kuhlukaniswe. Kulesi sihloko, sizoxoxa ngezimiso eziyisisekelo ze-centrifugation futhi sihlolisise ukusetshenziswa okuhlukahlukene kanye nezinhlobo ze-centrifuge ezisetshenziswa ezimbonini ezahlukene.

1. Izimiso Zoku-Centrifugation

Ngaphambi kokuhlola ubunkimbinkimbi be-centrifugation, kubalulekile ukuqonda izimiso ezingemuva kwale ndlela. Isimiso esiyinhloko esihilelekile lapha ukusetshenziswa kwamandla e-centrifugal ukuhlukanisa izingxenye zengxube. Uma isampula ifakwa ku-centrifuge futhi ijikeleziswa ngesivinini esikhulu, izinhlayiya eziqinile noma ama-molecule aya phansi, kuyilapho izinhlayiya ezingaqinile kakhulu zivame ukuhlala eduze kwaphezulu. Lokhu kuhlukana kwenzeka ngenxa yokuchitheka kwezinhlayiya eziqinile, okusheshiswa ngamandla e-centrifugal.

2. Izinhlobo Ezihlukene Zama-Centrifuge

Kunezinhlobo ezahlukene zama-centrifuge atholakalayo, ngalinye lenzelwe izinhlelo zokusebenza ezithile. Olunye uhlobo olusetshenziswa kakhulu yi-benchtop centrifuge, olusebenziseka kalula futhi oluthola ukusetshenziswa kwalo emalabhorethri emisebenzini ejwayelekile yokuhlukanisa. Olunye uhlobo yi-ultracentrifuge, ekwazi ukufinyelela isivinini esikhulu kakhulu futhi ikhiqize amandla amakhulu e-centrifugal, okwenza kube kuhle kakhulu emisebenzini edinga ukuhlukanisa izinhlayiya ezinobukhulu obuphansi kakhulu.

Ngakolunye uhlangothi, ama-centrifuge afakwe esiqandisini afakwe izinhlelo zokupholisa ezivumela ukuhlukaniswa kwamasampula azwela izinga lokushisa ngaphandle kokubeka engcupheni ubuqotho bawo. Lawa ma-centrifuge asetshenziswa kakhulu ezicelweni ezifana ne-molecular biology, lapho ukugcina izinga lokushisa elifanele kubalulekile khona.

3. Izicelo Zemitholampilo

Emkhakheni wokuxilonga ngokwezokwelapha, i-centrifugation idlala indima ebalulekile ekuhlaziyweni nasekuhlukanisweni kwamasampula egazi. Ngokujikelezisa amasampula egazi ku-centrifuge, ochwepheshe bezempilo bangahlukanisa izingxenye ezahlukene, njengezicubu ezibomvu zegazi, amaseli amhlophe egazi, kanye ne-plasma. Lokhu kuhlukaniswa kwenza kube lula ukuthola nokuthola izifo nezimo ezahlukahlukene, kanye nokuqoqwa kwezingxenye ezithile zegazi ngezinjongo zokwelapha.

4. Izicelo Zezimboni

I-Centrifugation isetshenziswa kabanzi ezinqubweni ezahlukene zezimboni. Isibonelo, embonini yokudla neziphuzo, ama-centrifuge asetshenziselwa ukuhlukanisa uketshezi nezinto eziqinile nokucacisa amajusi, amawayini, nezinye iziphuzo. Ngaphezu kwalokho, ama-centrifuge adlala indima ebalulekile ezitshalweni zokuhlanza amanzi angcolile, lapho esiza khona ekuhlukaniseni izinto eziqinile emanzini, okwenza kube lula ukulahla noma ukusebenzisa kabusha amanzi alungisiwe ngokuphephile.

5. Ucwaningo kanye ne-Biotechnology

Emalabhorethri ocwaningo kanye nezikhungo ze-biotechnology, i-centrifugation isetshenziswa kakhulu ezinhlotsheni ezahlukahlukene. Ivame ukusetshenziswa ukuhlanza amaprotheni, ukuhlukanisa ama-organelle eseli, ukuhlukanisa ama-nucleic acid, kanye nokuvuna amaseli kusuka kumidiya yokukhulisa amaseli. Lezi zinqubo zibalulekile ekwenzeni izivivinyo, ukutadisha izingxenye ezithile zamaseli, kanye nokuthuthukisa izixazululo zokwelapha.

Isiphetho

I-Centrifugation iyindlela ebalulekile evumela ukuhlukaniswa kwezingxube ezisetshenziswayo eziningana zesayensi, zezokwelapha, kanye nezezimboni. Ngokusebenzisa amandla amandla e-centrifugal, abacwaningi kanye nochwepheshe emikhakheni ehlukahlukene bangahlukanisa futhi bahlaziye izingxenye ezahlukene ngaphakathi kwesampula ngokunembile. Ukuguquguquka kanye nobubanzi bezicelo ze-centrifugation kwenza kube ithuluzi eliyisisekelo emalabhorethri emhlabeni wonke, kusiza emisebenzini esukela ezinqubweni zokuxilonga ezivamile kuya ocwaningweni oluqavile.
