i-centrifuge iyahlula njani ulwelo

Intshayelelo kwiCentrifugation kunye neMigaqo yayo

I-Centrifugation yindlela yokwahlula esetyenziswa kakhulu eguqule amashishini ahlukeneyo, kuquka amayeza, i-biotechnology, kunye nokulungiswa kokutya. Eli nqaku lijolise ekuphononongeni isayensi engasemva kwe-centrifugation kunye nendlela ehlula ngayo ulwelo ngokusekwe kubuninzi balo.

Ukuqonda Imigaqo yeCentrifugation

Kwisiseko sayo, i-centrifugation ixhomekeke ekusetyenzisweni kwamandla e-centrifugal, aveliswa ngokujikeleza isampuli kwi-axis ephakathi. La mandla adala intsimi yokwahlula evumela ukutyibilika kwamasuntswana okanye izinto ngokwesixa sazo okanye ubuninzi bazo. Izinto ezixineneyo ziya ngasemiphetho engaphandle, ngelixa izinto ezikhaphukhaphu okanye ulwelo zihlala zikufutshane nombindi.

Iintlobo zeeCentrifuges

Iindidi ezahlukeneyo ze-centrifuges ziyafumaneka, nganye ihambelana neemfuno ezithile zokwahlulwahlulwa. I-differential centrifugation, i-ultracentrifugation, kunye ne-density gradient centrifugation zezinye zeendlela ezisetyenziswa kakhulu. Ezi ndlela ze-centrifugation zahlukile ngokwesantya, uyilo lwe-rotor, kunye nokusetyenziswa, okuvumela ukusetyenziswa ngeendlela ezahlukeneyo kuphando nakwiimeko zoshishino.

I-Centrifugation eyahlukileyo yokwahlulwahlulwa

I-differential centrifugation yindlela esetyenziswayo ukwahlula amasuntswana anobukhulu obahlukeneyo kunye noxinano. Ngokulandela uthotho lwamanyathelo e-centrifugation aqala kwisantya esiphantsi ukuya kwisantya esiphezulu ngokuqhubekayo, kunokwenzeka ukufumana amasuntswana aneenxalenye ezahlukeneyo. Le ndlela isetyenziswa rhoqo kwibhayoloji yeseli ukukhupha nokwahlulahlula izinto zeseli ezifana nee-organelles, iiproteni, kunye nee-nucleic acids.

I-Ultracentrifugation yoKwahlulwa kweSisombululo esiPhakamileyo

I-Ultracentrifugation yindlela enamandla evumela izazinzulu ukuba zahlule izinto ezingaphantsi kweseli ngokuchanekileyo okukhulu. Le ndlela isebenzisa isantya esiphezulu kakhulu kwaye idla ngokufuna izixhobo ezikhethekileyo ezaziwa ngokuba yi-ultracentrifuges. Ezi zixhobo zinokujikelezisa iisampuli ngesantya esingaphezulu kwe-100,000 revolutions ngomzuzu, zivelise amandla amakhulu e-centrifugal.

I-Centrifugation ye-Density Gradient yoLwahlulo oluSebenzayo

I-centrifugation ye-density gradient isebenzisa umahluko woxinano lwezinto kwisampulu ukuze ifumane ulwahlulo olusebenzayo. Le ndlela ixhomekeke ekudaleni i-density gradient yokwenziwa, idla ngokusebenzisa isisombululo esenziwe nge-gradients ezahlukeneyo zetyuwa, iswekile, okanye ezinye iikhemikhali. Xa isetyenziswa i-centrifugation, isampuli iyahlukana ngokusekelwe kumahluko kuxinano, yenze imida okanye iindawo ezahlukeneyo.

I-Analytical Centrifugation yokuchonga iimpawu

Ngaphaya kokuhlukana, i-centrifugation ikwasetyenziselwa iinjongo zohlalutyo. I-analytical centrifugation ilinganisa utshintsho kwisantya se-sedimentation yee-molecules okanye amasuntswana, inika ulwazi oluxabisekileyo malunga nobukhulu bazo, imilo, kunye nobunzima bee-molecular. Le ndlela, eyaziwa ngokuba yi-sedimentation velocity okanye i-equilibrium centrifugation, idlala indima ebalulekileyo kwimimandla efana ne-biophysics, i-protein chemistry, kunye nee-polymers.

Izicelo ze-Centrifugation kwiShishini

I-Centrifugation isetyenziswa kakhulu kumashishini ahlukeneyo ngenxa yobuninzi bayo. Kwicandelo lezonyango, ii-centrifuge zibalulekile ekuhlukaniseni nasekucoceni amayeza ngexesha lokuvelisa. Amashishini okulungisa ukutya asebenzisa i-centrifugation ukwahlula izinto eziqinileyo kwizinto ezimanzi, ukucoca iziselo, kunye nokukhupha iioyile kwimbewu. Ukongeza, i-centrifugation isetyenziswa kwizityalo zonyango lwamanzi amdaka ukwahlula izinto eziqinileyo kunye nezinto ezimanzi ngokufanelekileyo.

Inkqubela phambili kwiTekhnoloji yeCentrifugation

Kwiminyaka edlulileyo, iteknoloji ye-centrifugation ibone inkqubela phambili ebalulekileyo. Ii-centrifuge zanamhlanje aziboneleli nje ngesantya esiphezulu sokujikeleza kodwa zikwabandakanya iimpawu ezifana nokuphathwa kweesampuli ngokuzenzekelayo, ulawulo lobushushu, kunye nokubeka esweni ngexesha langempela. Ezi nkqubela phambili zinika abaphandi kunye neengcali zoshishino ukusebenza kakuhle kunye nokuphindaphinda kwiinkqubo zabo zokwahlulahlula.

Isiphelo

I-Centrifugation itshintshe amashishini ahlukeneyo ngokubonelela ngendlela enamandla neguquguqukayo yokwahlula ulwelo ngokusekelwe kubuninzi balo. Nokuba kukwahlulahlula izinto zeseli okanye ukucoca iimveliso zamayeza, ii-centrifuge zidlala indima ebalulekileyo ekuphuculeni uphando kunye neenkqubo zoshishino. Ngokuqhubeka nophuhliso lwetekhnoloji, ikamva le-centrifugation lithembisa ukuchaneka nokusebenza kakuhle ngakumbi, nto leyo eguqula iinkalo ezininzi kunye nokusetyenziswa kwazo.
