Ingabe I-Centrifuge Ingawuhlukanisa Ngempela Usawoti Emanzini?

Isingeniso:

I-Centrifugation iyindlela esetshenziswa kabanzi emikhakheni eyahlukene, kusukela ocwaningweni lwesayensi kuya ekusetshenzisweni kwezimboni. Umbuzo ovamile ophakamayo ukuthi ingabe i-centrifuge ingahlukanisa usawoti emanzini ngempumelelo yini. Kulesi sihloko, sizohlola isayensi ye-centrifugation futhi sihlole ukuthi ingasetshenziswa kanjani ukuhlukanisa usawoti emanzini. Kusukela ekuqondeni izimiso zale ndlela kuya ekuhloleni ukulinganiselwa kwayo, sihlose ukunikeza umbono ophelele.

Isayensi Engemuva Kokuguquguqula I-Centrifugation:

1. Isimiso Samandla Aphakathi

Uma ingxube ifakwa ku-centrifuge, ifakwa amandla e-centrifugal. La mandla abangela ukuthi izingxenye ezixineneyo zihambe ziye odongeni lwangaphandle lwe-centrifuge tube, zakha i-pellet, kuyilapho izingxenye ezingaxinene kakhulu, njengoketshezi, zihlala ziseduze nesikhungo.

2. Ukuhlukaniswa Kosawoti Emanzini

Usawoti uncibilika kalula emanzini, wakhe ama-ion asatshalaliswa ngokulinganayo kulo lonke uketshezi. Ngenxa yokuthi ama-ion kasawoti ahlakazeka futhi awahlangani kakhulu, awathintwa amandla e-centrifugal. Ngenxa yalokho, ukusebenzisa nje i-centrifuge ukujikeleza ingxube kasawoti namanzi ngeke kuholele ekuhlukaneni kwawo.

Indima Yokucinywa Kwe-Density-Gradient:

Ukuze kuhlukaniswe usawoti emanzini kusetshenziswa i-centrifuge, kungasetshenziswa enye indlela ebizwa ngokuthi i-density-gradient centrifugation. Le ndlela incike ekudaleni i-density gradient ngaphakathi kwepayipi le-centrifuge.

3. Ukudalwa kwe-Density Gradient

I-density gradient ingakhiqizwa ngokungeza izinto ezifana ne-sucrose noma i-cesium chloride esixazululweni. Njengoba isixazululo sifakwa ku-centrifuge, izinto zakha i-gradient lapho i-density ikhula noma yehla kancane kancane ngobude bepayipi.

4. Inqubo Yokuhlukana

Uma ingxube ifakwa ku-centrifuge ku-density-gradient tube, izinhlayiya zikasawoti eziqinile zizohamba ziye esifundeni sobuningi obuphezulu, kuyilapho ama-molecule amanzi ehlala eduze nendawo ephakathi. Lokhu kuvumela ukuhlukaniswa okuyingxenye kosawoti emanzini.

Ukulinganiselwa kwe-Centrifugation:

5. Ukusebenza Kahle Nobumsulwa

Nakuba i-centrifugation ye-density-gradient ingenza kube lula ukuhlukaniswa kosawoti emanzini, kubalulekile ukuqaphela ukuthi ukuhlukaniswa okuphelele akutholakali ngaso sonke isikhathi. Usawoti othile ungase uhlale engxenyeni yamanzi, okuholela esixazululweni esingahlanzwanga ngokuphelele.

6. Okunye Ukungcola

I-Centrifugation isebenza kahle kakhulu ekuhlukaniseni izinto ngokusekelwe ekubuneni kwazo. Kodwa-ke, ayisusi okunye ukungcola, njengegesi encibilikisiwe, amakhemikhali e-organic, noma izinhlayiya ezilengayo ezingaba khona engxubeni yamanzi nosawoti.

7. Izidingo Zamandla

I-Centrifugation inqubo edinga amandla amaningi. Ukuze kufezwe ukuhlukaniswa okuphumelelayo, kudingeka isikhathi eside sokuphotha ngesivinini esikhulu, okungakhulisa ukusetshenziswa kwamandla okuphelele kwale nqubo.

Izicelo ze-Centrifugation:

8. Izicelo Zezimboni

I-Centrifugation isetshenziswa kabanzi ezimbonini ezahlukahlukene, okuhlanganisa nemithi, ubuchwepheshe bezinto eziphilayo, kanye nokucubungula ukudla. Ivame ukusetshenziselwa ukuhlukanisa izinto eziqinile koketshezi, kanye nokuhlanza nokugxilisa izinto ezahlukene.

9. Ucwaningo lwe-Molecular Biology

Ocwaningweni lwebhayoloji yama-molecule, i-centrifugation idlala indima ebalulekile ekuhlanzeni i-DNA, i-RNA, namaprotheni. Le ndlela ivumela ososayensi ukuthi batadishe futhi basebenzise la ma-molecule ukuze basebenzise izinhlelo ezahlukene, okuhlanganisa ubunjiniyela bezakhi zofuzo kanye nokuxilongwa.

Isiphetho:

Ukuhlanza nge-centrifugation, nakuba kungenakukwazi ukuhlukanisa usawoti omsulwa emanzini, kungaba yindlela ebalulekile ekusizeni inqubo yokuhlukanisa. Ngokusebenzisa i-centrifugation ye-density-gradient, kungenzeka ukuhlukanisa usawoti emanzini ngokwengxenye. Kodwa-ke, ukuhlanzwa okuphelele kungase kungatholakali ngale ndlela yodwa, njengoba kungasusi konke ukungcola. Naphezu kwemikhawulo yayo, ukuhlanza nge-centrifugation kuyaqhubeka nokuba ithuluzi eliwusizo ezinhlotsheni ezahlukene zesayensi nezimboni, okwenza kube lula ukuhlukanisa nokuhlanzwa kwezinto eziningi ezahlukene.
