Ukuqonda i-Centrifugation kunye nezicelo zayo
I-Centrifugation yindlela enamandla esetyenziswa kakhulu kumashishini ahlukeneyo nakwiindawo zesayensi ukwahlula, ukucoca, kunye nohlalutyo lwezinto ezahlukeneyo. Le nkqubo ibandakanya ukusetyenziswa kwe-centrifuge—umatshini ovelisa amandla okujikeleza ukuze wahlule izinto ngaphakathi kwesampuli ngokusekelwe kubuninzi bazo kunye nokuxinana kwazo. Ngokubeka isampuli kumandla amakhulu e-centrifugal, amasuntswana anzima okanye iikhompawundi zihlala ezantsi kwetyhubhu okanye kwisikhongozeli, ngelixa izinto ezikhaphukhaphu ziphakama ziye phezulu.
Isayensi Ebangela Ukwahlukana Kwe-Centrifugal
Umgaqo-siseko wesayensi osemva kokwahlulwa kwe-centrifugal usekwe ekulweni kwamandla athambileyo kunye namandla e-centrifugal. Xa isampuli ibekwe ngaphakathi kwe-centrifuge, ijikeleza ngokukhawuleza, idala amandla e-centrifugal adlula amandla adonsela phantsi asebenza kwisampuli. Oku kubangela ukwahlulwa kwezixhobo ngokusekelwe kubuninzi bazo, apho ezo zixineneyo zisiya ezantsi, zenze i-pellet, kwaye izixhobo ezikhaphukhaphu zinyuka ziye phezulu, zenze i-supernatant.
Ukuze kufezekiswe ukwahlukana okusebenzayo, kubalulekile ukuqwalasela izinto ezinje ngokukhethwa kwerotor, isantya, ubushushu, kunye nexesha. Ngokusebenzisa ezi zinto ziguquguqukayo, izazinzulu zinokwenza inkqubo ikwazi ukwahlula ngokufanelekileyo izinto ezithile ezinomdla, nto leyo ekhokelela kwimveliso ephezulu kunye nobunyulu.
Iintlobo zeeCentrifuges kunye nokusetyenziswa kwazo
IiCentrifuge zifumaneka kwiintlobo ezahlukeneyo, nganye yenzelwe ukusetyenziswa okuthile. Ezona ntlobo zisetyenziswa kakhulu ziquka ii-ultra-centrifuge, ii-microcentrifuge, ii-benchtop centrifuge, kunye nee-preparative centrifuge.
- Ii-Ultra-centrifuges: Ezi matshini zinamandla ziyakwazi ukuvelisa isantya esiphezulu kakhulu, zihlala zifikelela kwi-100,000 rpm ngomzuzu (RPM). Zisetyenziswa kuphando lwe-biochemical, ukulandelelana kwe-DNA, kunye nokuvelisa amayeza.
- Ii-Microcentrifuges: Ezi centrifuges zincinci zinamandla aphantsi kodwa zilungele uvavanyo oluncinci kwiilabhoratri. Zisetyenziselwa ukulungiselela isampuli ye-DNA kunye ne-RNA, inkcubeko yeseli, kunye nohlalutyo lweproteni.
- Ii-centrifuge ze-Benchtop: Zaziwa ngokuguquguquka kwazo kunye nokulula kokusetyenziswa, ii-centrifuge ze-benchtop zifumana ukusetyenziswa kwiilebhu zeklinikhi, kwi-biochemistry, nakwi-biotechnology. Zifanelekile ekulungiseleleni isampuli ngokubanzi, ekuhlukaniseni iinxalenye zegazi, nasekucoceni iiproteni.
- Ii-centrifuge zokulungiselela: Ezi matshini ziqinileyo zenzelwe ngokukodwa imisebenzi emikhulu yemizi-mveliso. Zixhaphake kakhulu kumashishini eekhemikhali kunye ne-biotechnology kwiinkqubo ezinje ngokuveliswa kwemithi yokugonya, ukuvunwa kweeseli, kunye nokucocwa kweeproteni ezinkulu.
Izicelo zeCentrifugation kwiMizi-mveliso nakwiSayensi
Ukucoca nge-centrifugation kudlala indima ebalulekileyo kumashishini amaninzi, kuquka amayeza, ukutya neziselo, isayensi yokusingqongileyo, kunye neekhemikhali zepetrochemicals.
Kwishishini lezemithi, i-centrifugation isetyenziswa ngexesha lophuhliso kunye nokuveliswa kwamayeza, inceda ekwahlukaniseni izithako ezisebenzayo zezemithi (ii-API) kwizinto ezingcolileyo, ubumdaka beeseli, kunye nezinye izinto ezingafunekiyo. Ikwasetyenziselwa ukwahlulahlula iinxalenye zegazi kwiibhanki zegazi, ivumela ukukhutshwa kweplasma, iiseli ezibomvu zegazi, kunye neeplatelets kwiinkqubo ezahlukeneyo zonyango.
Kwishishini lokutya neziselo, i-centrifugation inceda ekucaciseni ulwelo, olufana neejusi zeziqhamo, iwayini, kunye neebhiya, ukususa intlenga kunye nokuphucula ukucaca kwemveliso. Ikwasetyenziswa ekuveliseni ioyile yomnquma, yahlula ioyile emanzini kunye nezinto eziqinileyo. Ukongeza, idlala indima ebalulekileyo ekucutshungulweni kobisi, ivumela ukwahlulwa kwekhrimu kubisi.
Kwicandelo lesayensi yokusingqongileyo, i-centrifugation ibalulekile ekuhlalutyeni iisampuli zomhlaba, unyango lwamanzi amdaka, kunye nokufunda iintsholongwane kwiindawo eziphilayo zasemanzini. Inceda ekwahlukaniseni iinxalenye eziqinileyo emanzini, iququzelela uhlalutyo oluchanekileyo kunye nokubeka esweni izinto ezingcolisayo kokusingqongileyo.
Ishishini le-petrochemical lisebenzisa kakhulu i-centrifugation ukwahlula iikhompawundi ze-oyile ekrwada, ukucoca ii-lubricants, kunye nokuphucula ukusebenza kakuhle kokucocwa kweoyile. Uvavanyo lolawulo lomgangatho kunye nemisebenzi yophando kunye nophuhliso ixhamla ngakumbi kwiindlela ze-centrifugation.
Iingozi kunye nokulinganiselwa kwi-Centrifugal Diparation
Nangona i-centrifugation iyindlela enamandla neyimfuneko, inemingcipheko ethile kunye nemida ekufuneka iqwalaselwe. I-centrifugation ekhawulezayo inokuvelisa ubushushu obukhulu, enokuchaphazela ukuthembeka kwesampuli okanye itshintshe uzinzo lweekhompawundi zebhayoloji. Ngaphezu koko, ukuseta okungafanelekanga kweetyhubhu okanye ii-rotors, ukungaphumeleli ukulinganisela iisampuli, okanye ukudlula isantya esiphezulu esicetyiswayo kunokubangela ukungaphumeleli kwezixhobo, okubangela umngcipheko wokhuseleko.
Omnye umda ubandakanya ukubakho kongcoliseko oludibanisayo xa kusetyenzwa iisampulu ezininzi kwi-rotor enye okanye ukungaphumeleli ukucoca i-centrifuge kakuhle phakathi kokuhamba. Olu ngcoliseko lunokukhokelela kwiziphumo zovavanyo ezingachanekanga okanye ukucoceka kweisampulu.
Ukongeza, izinto ezithile zisenokungahambelani ne-centrifugation ngenxa yeempawu zazo okanye uvakalelo lwazo. Iisampuli ezinobuzwelo kubushushu, iikhompawundi eziguquguqukayo, okanye izinto eziphilayo ezibuthathaka zinokufuna iindlela ezahlukeneyo zokwahlula ukuqinisekisa ukuthembeka kwazo.
Ukuqukumbela, i-centrifugation yinkqubo ebalulekileyo esetyenziswa kumashishini ahlukeneyo nakwiindawo zesayensi. Ukuqonda isayensi engasemva kokwahlulwa kwe-centrifugal, ukusebenzisa uhlobo olufanelekileyo lwe-centrifuge, kunye nokuqwalasela imida enxulumene nale ndlela kubalulekile ekuphuhliseni ngempumelelo, ekucoceni, nasekuhlalutyeni izinto ezahlukeneyo.
