Uketshezi lwe-centrifuge luthuthukisa kanjani ukusebenza kahle kokuhlukaniswa koketshezi?

Indima Yoketshezi Lwe-Centrifuge Ekuthuthukiseni Ukusebenza Kahle Kokuhlukanisa Uketshezi

I-Centrifugation iyindlela yokuhlukanisa esetshenziswa kabanzi emalabhorethri, ezinqubweni zezimboni, nasezikhungweni zocwaningo. Yenzelwe ukuhlukanisa izingxenye zengxube yoketshezi ngokusekelwe ekubuneni kwazo, usayizi, kanye nesimo. Ukusebenza kahle kwenqubo ye-centrifugation kungathuthukiswa kakhulu ngokusebenzisa uketshezi lwe-centrifuge, olusebenza njengendlela yokwandisa ukuhlukaniswa kwezingxenye ezahlukene.

Ukuqonda i-Centrifugation kanye nokuhlukaniswa koketshezi

I-Centrifugation inqubo ehilela ukusetshenziswa kwe-centrifuge ukuhlukanisa izinhlayiya esixazululweni ngokuya ngobukhulu bazo, ukuma, ubuningi, ukujiya kwe-medium, kanye nesivinini se-rotor. Uma uketshezi lwe-centrifuge lungezwa, kusiza ekufezeni ukuhlukaniswa okungcono ngokudala indawo evumayo yokuthi izinhlayiya zihlale ngesivinini sazo esifanele. Uketshezi lwe-centrifuge lusebenza njengomqamelo wezinhlayiya njengoba zihamba ngamandla e-centrifugal, okwenza kube lula ukuhlukaniswa kwezingxenye.

Inqubo yokuhlukaniswa koketshezi ku-centrifuge isekelwe ezimisweni zokuthungwa kanye nobuningi be-buoyant. Ukuthungwa kubhekisela emandleni adonsela phansi asebenza ezinhlayiyeni, okubangela ukuba zihlale phansi kwepayipi le-centrifuge. Ngakolunye uhlangothi, ubukhulu be-buoyant yisimiso esinquma izinga lapho izinhlayiya ziphakama noma zicwila khona kuketshezi lwe-centrifuge, ngokusekelwe ekubuneni kwazo uma kuqhathaniswa nendawo. Ukusetshenziswa koketshezi lwe-centrifuge kusiza ekwenzeni ngcono lezi zimiso ukuze kufezwe ukuhlukaniswa okuphumelelayo kwezingxenye zoketshezi.

Izinhlobo Zoketshezi Lwe-Centrifuge

Kunezinhlobo ezahlukene zoketshezi ezingasetshenziswa ekuhlanganiseni ukuze kuthuthukiswe inqubo yokuhlukanisa uketshezi. Ukukhethwa koketshezi lwe-centrifuge kuncike ohlotsheni lwesampula ecutshungulwayo kanye nezidingo ezithile zokuhlukanisa. Izinhlobo ezivamile zoketshezi lwe-centrifuge zifaka amanzi, izinyibilikisi eziphilayo, imidiya ye-density gradient, kanye nezixazululo ze-buffer.

Amanzi ayiketshezi elisetshenziswa kakhulu le-centrifuge, ikakhulukazi ekusetshenzisweni okujwayelekile kokuhlukanisa. Ahlinzeka ngendlela elula nengabizi kakhulu yokuhlukanisa izingxenye ngokusekelwe ekuminyaneni nasesayizini. Izinyibilikisi ze-organic, njenge-ethanol noma i-isopropanol, zisetshenziswa lapho kudingeka kuhlangatshezwane nezidingo ezithile zokuncibilika kanye nobuningi. Lezi zinyibilikisi zingasiza ekufezeni ukuhlukaniswa okungcono kwamakhemikhali e-organic noma amasampula e-biological.

Imidiya ye-density gradient, njenge-sucrose noma i-cesium chloride, isetshenziswa lapho kudingeka ukuhlukaniswa okunembe kakhudlwana kwezinhlayiya. Lezi midiya zakha i-density gradient ngaphakathi kwe-centrifuge tube, okuvumela izinhlayiya ukuthi zithuthele ekujuleni kwazo okuqondile ukuze zihlukaniswe kahle. Ngakolunye uhlangothi, izixazululo ze-buffer zisetshenziselwa ukugcina i-pH kanye namandla e-ionic esampula ngesikhathi se-centrifugation, kuyilapho futhi zihlinzeka ngendawo efanelekile yokuhlukaniswa kwezinhlayiya.

Ukuthuthukisa Ukusebenza Kahle Nge-Centrifuge Liquids

Ukwengezwa koketshezi lwe-centrifuge kuthuthukisa kakhulu ukusebenza kahle kwenqubo yokuhlukanisa uketshezi ngezindlela eziningana. Okokuqala, kunikeza indlela yokunciphisa ukungqubuzana phakathi kwezinhlayiya kanye nethubhu le-centrifuge, okuvumela ukuthungwa okubushelelezi nokusheshayo. Lokhu kuphumela ekuhlukanisweni okusheshayo kwezingxenye, kunciphisa isikhathi sokucubungula sonke.

Okwesibili, ukusetshenziswa koketshezi lwe-centrifuge kusiza ekudaleni indawo ezinzile ukuze izinhlayiya zihlale, okuholela ekuxazululweni okungcono kanye nokucaca kwezinto ezihlukanisiwe. Lokhu kubaluleke kakhulu lapho kubhekene nezingxube eziyinkimbinkimbi noma amasampula aqukethe ububanzi obukhulu bezinhlayiya. Uketshezi lwe-centrifuge luqinisekisa ukuthi ukuhlukaniswa kufezwa ngokuphazamiseka okuncane noma ukuxubana kwezingxenye.

Ngaphezu kwalokho, uketshezi lwe-centrifuge lungasiza ekususweni kokungcola nokungcola okuvela kusampula ngesikhathi senqubo yokuhlukanisa. Ngokudala umgoqo phakathi kwezinhlayiya nendawo ezungezile, uketshezi lwe-centrifuge lusiza ekugcineni ubumsulwa bezingxenye ezihlukanisiwe, okuholela emiphumeleni yekhwalithi ephezulu.

Izici Ezithonya Ukusebenza Kahle Kokuhlukaniswa Koketshezi

Izinto eziningana zithonya ukusebenza kahle kokuhlukaniswa koketshezi ku-centrifuge, futhi ukukhetha uketshezi lwe-centrifuge kudlala indima ebalulekile ekwenzeni lezi zici zibe ngcono. Ukuthambekela koketshezi lwe-centrifuge kubalulekile, njengoba kuthinta ukugeleza nokuqina kwezinhlayiya ngaphakathi kwendawo. Uketshezi olune-viscosity ephansi lungasiza ekusheshiseni ukuthuthwa kwamanzi, kuyilapho uketshezi olune-viscosity ephezulu lungadingeka ukuze kuhlukaniswe kahle.

Ubuningi kanye nokuqina koketshezi lwe-centrifuge nakho kuthinta ukusebenza kahle kokuhlukaniswa koketshezi. Ukuphakama kobuningi obulinganisiwe kahle ngaphakathi kwendawo kungasiza ekufinyeleleni ukuhlukaniswa okunembile kwezinhlayiya ngokusekelwe ekubuthweni kwazo okuthambile. Ukuqina koketshezi lwe-centrifuge kuqinisekisa ukuthi lugcina izakhiwo zalo kuyo yonke inqubo ye-centrifugation, ngaphandle kokuhlukaniswa kwesigaba noma ukuwohloka.

Izinga lokushisa loketshezi lwe-centrifuge lingathonya ukusebenza kahle kokuhlukanisa, njengoba lithinta amandla e-kinetic kanye nokuziphatha kokuhlala kwezinhlayiya. Ukugcina izinga lokushisa elifanele kakhulu loketshezi lwe-centrifuge kubalulekile ukuvimbela noma yikuphi ukuguquguquka enkambisweni yokuhlukanisa. Ngaphezu kwalokho, ukuhambisana kwamakhemikhali koketshezi lwe-centrifuge nesampula ecutshungulwayo kubalulekile ukugwema noma yikuphi ukusabela okungafuneki noma ukuphazamiseka kokuhlukanisa.

Ukusetshenziswa kwe-Centrifuge Liquid Ezimbonini Ezihlukahlukene

Ukusetshenziswa koketshezi lwe-centrifuge ekuthuthukiseni ukusebenza kahle kokuhlukanisa uketshezi kuthola ukusetshenziswa kuzo zonke izimboni kanye nezinkambu zocwaningo ezahlukahlukene. Ocwaningweni lwezinto eziphilayo kanye nezamakhemikhali, uketshezi lwe-centrifuge lusetshenziselwa ukuhlukanisa izingxenyana ezingaphansi kweseli, ukuhlanzwa kwamaprotheni, kanye nokuhlukanisa ama-nucleic acid ezingxubeni eziyinkimbinkimbi. Ukukhethwa koketshezi lwe-centrifuge kulezi zicelo kulungiselelwe izidingo ezithile zesampula kanye nobumsulwa obufunwayo bezingxenye ezihlukanisiwe.

Ezimbonini zemithi kanye ne-biopharmaceutical, uketshezi lwe-centrifuge ludlala indima ebalulekile ekuhlanzweni nasekuhlukanisweni kwezinto zemithi, imijovo, kanye ne-biologics. Ukusetshenziswa kwe-density gradient media eku-centrifuge kwenza kube nokuhlukaniswa kwezinhlayiya ezithile nama-molecule, okuholela ekukhiqizweni kwemikhiqizo yemithi esezingeni eliphezulu.

Imikhakha yokwelapha imvelo kanye namanzi angcolile isebenzisa uketshezi lwe-centrifuge ukuze ihlukanise futhi icacise ukungcola okuvela emanzini kanye nokungcola kwezimboni. Ngokusebenzisa uketshezi lwe-centrifuge olufanele, lezi zimboni zingafinyelela ekususweni okuphumelelayo kwezinto eziqinile ezilengayo, izinto eziphilayo, kanye nokunye ukungcola okuvela emfuleni woketshezi, ukuqinisekisa ukulandelwa kwemithethonqubo yezemvelo.

Embonini yokudla neziphuzo, uketshezi lwe-centrifuge lusetshenziswa ukuhlukaniswa kwezinto eziqinile kanye noketshezi ekukhiqizweni kwamajusi, uwoyela, kanye nemikhiqizo yobisi. Ngokusebenzisa uketshezi lwe-centrifuge olunezakhiwo ezilungiselelwe wena, njenge-viscosity kanye nobuningi, abakhiqizi bangafinyelela ukuhlukaniswa okuhle kakhulu kwezingxenye ngenkathi begcina ikhwalithi kanye nenani lokudla okunempilo kwemikhiqizo yokugcina.

Isifinyezo

Ekuphetheni, ukusetshenziswa koketshezi lwe-centrifuge kubalulekile ekuthuthukiseni ukusebenza kahle kokuhlukaniswa koketshezi ezinqubweni zokuxuba. Ukukhetha uketshezi lwe-centrifuge, ngokusekelwe ezimpahleni zalo kanye nokuhambisana nesampula, kungathinta kakhulu ikhwalithi kanye nesivinini sokuhlukaniswa. Ngokuqonda izimiso ezingemuva kokuxuba kanye nendima yoketshezi lwe-centrifuge, izimboni kanye nezikhungo zocwaningo zingenza ngcono izinqubo zazo zokuhlukanisa uketshezi ukuze kutholakale imiphumela emihle kuzo zonke izinhlelo zokusebenza ezahlukahlukene. Njengoba ubuchwepheshe buthuthuka kanye nesidingo samasu okuhlukanisa aqondile sikhula, indima yoketshezi lwe-centrifuge ekusebenzeni kahle kokuhlukanisa uketshezi izoqhubeka nokuba yinto ebalulekile ekusungulweni nasekuthuthukisweni emkhakheni wokuxuba uketshezi.
