I-Centrifuge Yahlula Njani Izinto?

Intshayelelo:

I-centrifuge sisixhobo esinamandla selabhoratri esidlala indima ebalulekileyo ekwahlukaniseni izinto ezahlukeneyo zesampulu ngokusebenzisa amandla e-centrifugal. La mandla aveliswa kukujikeleza okuphezulu kwe-centrifuge, okuvumela ukwahlula izinto ezinobunzima obahlukeneyo okanye ubukhulu beesuntswana. Kweli nqaku, siza kuhlola iindlela zangaphakathi ze-centrifuge size sihlolisise iindlela ezahlula ngayo izinto ngokufanelekileyo. Siza kuxoxa nangokusetyenziswa kwe-centrifugation kwiindawo ezahlukeneyo, ukusuka kwi-diagnostics yezonyango ukuya kwiinkqubo zoshishino.

I. Ukuqonda i-Centrifugation:

I-Centrifugation yinkqubo esebenzisa umgaqo we-sedimentation, isebenzisa amandla aveliswa yi-spinning centrifuge. La mandla atyhala amasuntswana okanye izinto ezixineneyo ukuya ezantsi kwetyhubhu yesampuli, ngelixa izinto ezikhaphukhaphu zihlala ziphezulu. Ngamazwi alula, i-centrifuge isebenza njenge-merry-go-round ejikelezayo ngokukhawuleza, yahlula izinto kwisampuli ngokusekelwe kubuninzi bazo.

II. Ukusebenza kweCentrifuge:

A. Indibano yeRotor yeCentrifuge:

Indibano yerotor ye-centrifuge yinxalenye ebalulekileyo enoxanduva lokujikeleza ngesantya esiphezulu esifunekayo ngexesha lokwahlulwa. Iquka i-spindle, iityhubhu zesampulu, kunye neebhakethi okanye izibambi ezikhethekileyo. Isantya sokujikeleza sinokufikelela kumawaka amaninzi okujikeleza ngomzuzu (rpm), nto leyo edala amandla afunekayo e-centrifugal.

B. Amandla eCentrifugal:

Xa i-rotor iqala ukujikeleza, ivelisa amandla e-centrifugal atsala izinto ziphume zisuka embindini wokujikeleza. La mandla e-centrifugal anoxanduva lwenkqubo yokwahlulahlula.

III. Iintlobo ezahlukeneyo zeeCentrifuges:

A. IiCentrifuge zokulungiselela:

Ii-centrifuge zokulungiselela zenzelwe ukwahlula ubungakanani obukhulu beesampuli. Zisetyenziswa kakhulu kwiilebhu zophando kunye namashishini amayeza ngeenjongo ezinkulu zokwahlula nokucoca. Umthamo wetyhubhu ye-centrifuge kwezi modeli mkhulu kakhulu, nto leyo evumela ukucutshungulwa kweesampuli ezinkulu.

B. IiCentrifuge zoHlalutyo:

Kwelinye icala, ii-centrifuge zohlalutyo zisetyenziselwa ubungakanani obuncinci besampulu kwaye zihlala zisetyenziswa kuhlalutyo oluneenkcukacha lwezinto. Ezi centrifuge zisebenza ngesantya esiphezulu, zibonelela ngokwahlulahlula nokuqhekeza ngokuchanekileyo.

IV. Iindlela zoKwahlula:

A. Ukwahlulahlula iCentrifugation:

I-differential centrifugation yindlela exhomekeke kwiindidi ezahlukeneyo zezinto ukuze zizahlule. Ngokulungisa isantya kunye nobude benkqubo ye-centrifugation, izinto ezinoxinano olwahlukeneyo zihlala kwiindawo ezahlukeneyo kwityhubhu ephumeleleyo. Izinto ezixineneyo ziyaqokelelana ezantsi, ngelixa izinto ezikhaphukhaphu zenza iileya ezahlukeneyo ngaphezulu.

B. I-Centrifugation ye-Density Gradient:

Kwi-centrifugation ye-density gradient, i-gradient yokwanda okanye ukwehla koxinano lwenziwa kwityhubhu ye-centrifuge. Ngokusebenzisa amandla e-centrifugal, izinto zesampulu ziya kwiindawo ezithile kwi-gradient ngokusekelwe kuxinano lwazo ngalunye. Le ndlela ifanelekile ukwahlula amasuntswana, ii-biomolecules, kunye nee-organelles ezinomahluko omncinci kuxinano.

V. Ukusetyenziswa kweCentrifugation:

A. Uxilongo lwezonyango nolwezonyango:

I-Centrifugation idlala indima ebalulekileyo ekuxilongweni kwezonyango nakwezonyango. Isetyenziselwa uhlalutyo lweesampuli zegazi, njengokwahlula i-plasma okanye i-serum egazini elipheleleyo kunye nokwahlula iinxalenye ezithile zegazi ezifana neeseli zegazi ezibomvu nezimhlophe okanye iiplatelets. Ikwasetyenziswa kwiilabhoratri ze-microbiology ukwahlula iintsholongwane okanye ezinye iintsholongwane kwimidiya yokukhulisa izityalo.

B. Ishishini lokutya neziselo:

I-Centrifugation isetyenziswa kakhulu kwishishini lokutya neziselo ngeenjongo ezahlukeneyo, kuquka ukwahlula ukhilimu kubisi, ukucacisa iijusi zeziqhamo, kunye nokwahlula intlenga kwiwayini okanye ibhiya, ukubonelela ngolawulo lomgangatho kunye nokuphucula ixesha lokuphelelwa kwemveliso.

C. Uhlalutyo lweNdalo:

Kuhlalutyo lokusingqongileyo, i-centrifugation isetyenziselwa ukwahlula izinto ezingcolisayo, inkunkuma, kunye neentsholongwane. Ngokuhlukanisa izinto ezinomdla, izazinzulu zinokuhlalutya kwaye zichonge izinto ezingcolisayo, zijonge umgangatho wamanzi, kwaye zihlole iingozi kunye nempembelelo yokusingqongileyo.

D. Iinkqubo zeShishini:

Iinkqubo ezininzi zoshishino, ezinje ngokucocwa kweoyile, unyango lwamanzi amdaka, kunye nokuveliswa kwamayeza, zixhomekeke kwi-centrifugation ngeenjongo zokwahlula nokucoca. Ukwahlula ukungcola, ukufumana iimveliso ezixabisekileyo, kunye nokuqinisekisa ukusebenza kakuhle kunye nobunyulu bemveliso yokugqibela zizinto ezibalulekileyo kwezi zicelo.

E. Uphando noPhuhliso:

Okokugqibela, i-centrifugation sisixhobo esibalulekileyo esisetyenziswa kwiindawo ezahlukeneyo zophando nophuhliso. Ukusetyenziswa kwayo kuqala ekuhlukaniseni i-DNA, i-RNA, okanye iiproteni kwizifundo zemfuza, ukufunda ii-organelles zeeseli, kunye nokulungiselela iisampulu zohlalutyo lwe-electron microscopy ukubiza ezimbalwa.

Isiphelo:

I-Centrifugation, kunye nokukwazi kwayo ukwahlula izinto ngokufanelekileyo ngokusekelwe kubuninzi bazo, yindlela esisiseko esetyenziswa kwiindawo ezahlukeneyo. Ukusuka ekuxilongweni kwezonyango ukuya kwiinkqubo zoshishino, amandla ajikelezayo e-centrifuge adlala indima ebalulekileyo ekwahlukaniseni izinto ezahlukeneyo ukuze kuhlalutywe, kucocwe, kwaye kulawulwe umgangatho. Ngokuqhubela phambili okuqhubekayo kubuchwepheshe kunye nokuguquguquka okwandileyo, ii-centrifuge ziya zichaneka kwaye zithembeke, zivula amathuba amatsha okufunyanwa kwesayensi kunye nokuqhubela phambili kwezoshishino.
