Zivumela izazinzulu ukuba zahlule, zicoce, kwaye zihlalutye uluhlu olubanzi lweesampuli, kuquka ulwelo lwebhayoloji, iiseli, iimolekyuli, kwanee-nanoparticles. Ngokusebenzisa imigaqo ye-centrifugation, ezi zixhobo zahlula izinto ezithile kumxube owahlukileyo, nto leyo evumela abaphandi ukuba bazifunde kwaye baziqonde ngcono.
II. Umgaqo weCentrifugation
Ukufakwa kwe-centrifugation kuxhomekeke kwingcamango ye-sedimentation, eyenzeka ngenxa yobuninzi obahlukeneyo bee-particles ezixhonywe kwindawo engamanzi. Xa isampuli ifakwa kwi-centrifuge rotor kwaye ijikeleziswa ngokukhawuleza, kusetyenziswa amandla e-centrifugal kumxube. La mandla atyhala ii-particles ezixineneyo ziye ezantsi kwesisombululo, enze i-pellet, ngelixa ii-particles ezikhaphukhaphu zihlala kwi-supernatant.
III. Iintlobo zeeCentrifuges
1. IiCentrifuge zokwahluka:
Ii-centrifuge ezahlukeneyo zisebenza ngesantya esiphantsi kunezinye iintlobo kodwa zilungele ukwahlula amasuntswana amakhulu okanye izinto zeseli kwi-suspensions okanye kwi-lysates.
2. IiCentrifuge zokulungiselela:
Ii-centrifuge zokulungiselela zinokuphatha iisampulu ezinkulu ngesantya esiphezulu kunee-centrifuge ezihlukeneyo. Zivumela ukwahlukana okukhawulezayo nokusebenzayo, nto leyo ezenza zifaneleke kwiinkqubo zokucoca ezinkulu.
3. Ii-Ultracentrifuges:
Ii-Ultracentrifuges zezona zinto zisebenzayo kwisayensi yokwahlulahlula. Ezi matshini zisebenza ngesantya esiphezulu kakhulu kunye namaqondo obushushu, zikwazi ukwahlula nee-macromolecules ezilungileyo okanye ii-subcellular particles. I-Ultracentrifugation idla ngokusetyenziswa kuphando lwe-biochemical, inceda ekuhlukaniseni ii-organelles kunye nee-complexes ezinkulu.
IV. Ukusetyenziswa kweCentrifugation
1. Izicelo zezonyango nezeklinikhi:
IiCentrifuges zisetyenziswa kakhulu kwiilabhoratri zonyango ukuhlalutya igazi, umchamo, kunye nolunye ulwelo lomzimba. Kuvavanyo lokuxilonga, zahlula iiseli kwi-serum okanye kwi-plasma ukuze zichonge izinto ezingaqhelekanga okanye zichonge iiparameter ezahlukeneyo zegazi.
2. Ishishini leMithi:
Ukucoca nge-centrifuge kudlala indima ebalulekileyo ekufumaneni nasekuphuhlisweni kwamayeza. Kunceda ekwahlukaniseni nasekucoceni izithako ezisebenzayo zamayeza, okuvumela uhlalutyo olongezelelweyo kunye nokwenziwa kwawo. Ukongeza, ukucoca nge-centrifuge kusetyenziswa ngexesha lokuveliswa kwamayeza okugonya, ukususa amasuntswana eentsholongwane okanye ukucoca iiproteni eziphinda zihlangane.
3. Uhlalutyo lweNdalo:
Kwisayensi yokusingqongileyo, i-centrifugation iluncedo ekuhlalutyeni iisampulu zomhlaba namanzi. Ukwahlula amasuntswana axhonyiweyo kwi-matrices yokusingqongileyo kwenza abaphandi bakwazi ukufunda iipatheni ze-sedimentation, bavavanye amanqanaba ongcoliseko, kwaye bahlalutye ukufumaneka kwezondlo.
4. Ibhayoloji yeemolekyuli kunye neGenetics:
Iindlela zokucoca zibaluleke kakhulu kuphando lwebhayoloji yeemolekyuli. Ngexesha lokukhupha i-DNA, ii-centrifuges zahlula iiseli kwiindawo ezizingqongileyo, zivumela ukucocwa okulandelayo kunye nokucocwa kwezinto zemfuza. Ngaphezu koko, ukwahlulwa kwezinto ezingaphantsi kweseli, ezifana ne-mitochondria okanye i-ribosomes, kunceda ekufundeni iinkqubo zeseli kunye nokuhlanganiswa kweproteni.
