Idlala yiphi indima isitya esisicaba ekusebenzeni kwe-centrifuge?
IiCentrifuge zizixhobo ezibalulekileyo kumashishini ahlukeneyo, ukusuka kuphando lwesayensi ukuya kunyango ukuya ekulungisweni kokutya. Ezi matshini zisebenzisa imigaqo yamandla ecentrifugal ukwahlula izinto ngokusekelwe kubuninzi bazo, nto leyo ekhokelela ekuhlukanisweni kwezinto ezifana neeseli, iiproteni, okanye amasuntswana. Embindini weCentrifuge kukho isitya esisityhubhu, into ebalulekileyo edlala indima ebalulekileyo ekusebenzeni komatshini.
Umsebenzi weSitya seTubular
Isitya esisicaba siyinxalenye ebalulekileyo ye-centrifuge, sisebenza njengegumbi apho kubekwa khona izinto eziza kwahlulwa. Esi sitya sijikeleza ngesantya esiphezulu, senza amandla e-centrifugal abangela ukuba amasuntswana axineneyo aphume aze ahlale eludongeni lwesitya, ngelixa izinto ezingaxineneyo zihlala zisondele embindini. Olu hlulo luvumela ukukhutshwa kwezinto ezithile ngokusekelwe kuxinano lwazo, okuvumela amashishini ahlukeneyo ukuba enze iinkqubo ezinje ngokwahlula iiseli zegazi, ukwahlulwa kwe-DNA, kunye nokulungiswa kwamayeza.
Uyilo lwesitya esisityhubhu lubaluleke kakhulu kumsebenzi waso. Imilo kunye nobukhulu besitya zilungiswe ngononophelo ukuqinisekisa ukwahlukana okusebenzayo. Ijiyometri yesitya, kuquka ubude kunye nobubanzi baso, kunye ne-engile yeziphelo zekhoni, zonke zenziwe ngendlela yokuba zifezekise amandla afunekayo e-centrifugal kunye nokusebenza kakuhle kokwahlukana. Ukongeza, izinto zesitya kufuneka zikhethwe ngononophelo ukuze zimelane nesantya esiphezulu kunye namandla abandakanyekayo ekuxibilikiseni, ukuqinisekisa ukuba isitya sinokunyamezela ubunzima bokusebenza kwaso.
Indima yeSitya seTubular ekulungiseleleni isampuli
Kwicandelo lophando lwesayensi kunye nokuxilongwa kwezonyango, ukulungiselela isampuli linyathelo elibalulekileyo elichaphazela ngokuthe ngqo ukuchaneka kunye nokuthembeka kohlalutyo olulandelayo. Ii-Centrifuge zihlala zisetyenziselwa ukulungiselela isampuli, kwaye isitya setyhubhu siphambili kule nkqubo. Ngokujikeleza iisampulu ngesantya esiphezulu, i-centrifuge yahlula izinto ngokusekelwe kubuninzi bazo, ivumela abaphandi kunye neengcali zokuxilonga ukuba bahlukanise izinto ezithile kwimixube enzima.
Kwimeko yokulungiselela isampuli yegazi, umzekelo, isitya esinomqolo senza ukuba igazi lihlukaniswe libe zizinto ezahlukeneyo, ezinje ngeeseli ezibomvu zegazi, iiseli ezimhlophe zegazi, iiplatelets, kunye neplasma. Olu buchule lubalulekile ekuxilongweni kwezonyango, njengoko luvumela iingcali zezempilo ukuba zihlalutye izinto ezithile zegazi ukuze zifumane iimpawu zesifo, usulelo, okanye ezinye iimpawu zempilo. Ngaphandle kwamandla e-centrifugal aveliswa sisitya esinomqolo, ukwahlukana okuchanekileyo okunjalo bekungenakwenzeka, nto leyo egxininisa indima ebalulekileyo yale nxalenye kwiinkqubo zokulungiselela isampuli.
Ngaphezu koko, amandla esi sitya setyhubhu okwahlula iisampulu ngokufanelekileyo abaluleke kakhulu kwiindawo zophando lwesayensi. Abaphandi badla ngokufuna ukwahlula iimolekyuli okanye amasuntswana athile kwimixube yebhayoloji okanye yeekhemikhali eyinkimbinkimbi, kwaye ukujikelezisa ngesitya setyhubhu kunika indlela enamandla yokufezekisa le njongo. Nokuba kukwahlula ii-organelles ezingaphantsi kweseli, ukucoca i-DNA kunye ne-RNA, okanye ukwahlula iiproteni ukuze kuhlalutywe nge-biochemical, isitya setyhubhu se-centrifuge senza izazinzulu zikwazi ukwenza amalungiselelo esampuli abalulekileyo ngokuchanekileyo nangokuphindaphindwayo.
Ukubaluleka kwezixhobo zesitya seTubular kunye nokwakhiwa kwaso
