Nws ua rau tshem tawm cov khoom tsis huv, sib cais cov khoom khov ntawm cov kua, thiab kev sib sau ua ke ntawm cov tshuaj xav tau.
2.3 Kev Tshuaj Xyuas Ib Puag Ncig:
Hauv kev tshuaj xyuas ib puag ncig, centrifugation pab txhawb rau kev sib cais cov khoom me me, cov av noo, thiab cov pa phem ntawm cov qauv dej. Nws pab nrhiav cov pa phem, kawm txog cov kab mob me me, thiab tshuaj xyuas cov av sib xyaw, ua rau nws yog ib qho cuab yeej tseem ceeb rau cov kws tshawb fawb thiab cov kws tshawb fawb ib puag ncig.
2.4 Kev Lag Luam Khoom Noj thiab Dej Haus:
Kev lag luam khoom noj thiab dej haus siv centrifugation rau ntau lub hom phiaj, suav nrog kev ua kom cov kua txiv ntshiab, kev sib cais cov mis nyuj qab zib los ntawm mis nyuj, kev rho tawm cov roj, thiab kev tshem tawm cov khoom tsis huv ntawm cov khoom noj. Nws ua kom ntseeg tau tias muaj cov khoom zoo thiab huv si.
2.5 Cov Txheej Txheem Tshuaj Lom Zem thiab Kev Lag Luam:
Kev siv centrifugation pom muaj kev siv dav hauv cov txheej txheem tshuaj lom neeg thiab kev lag luam rau kev sib cais, kev ntxuav, thiab kev sib sau ua ke ntawm cov tshuaj sib txawv. Nws pab hauv kev sib cais cov catalysts, rov qab tau cov khoom muaj nqis, kev tshem tawm cov dej khib nyiab, thiab kev ntxuav cov tshuaj.
III. Cov txiaj ntsig ntawm Centrifugation:
3.1 Kev Ceev thiab Kev Ua Haujlwm Zoo:
Kev siv centrifugation yog ib txoj kev sib cais sai, uas muaj peev xwm ua tiav kev sib cais tag nrho hauv ob peb feeb xwb. Nws sai dua piv rau lwm txoj kev sib cais xws li kev lim dej lossis kev tso dej rau hauv av. Qhov kev sib hloov ceev ceev ua rau muaj zog centrifugal, ua rau kev sib cais zoo.
3.2 Kev Xaiv:
Kev siv centrifugation muaj kev xaiv tau, ua rau muaj kev sib cais ntawm cov khoom raws li lawv qhov loj me, cov duab, thiab qhov ceev. Los ntawm kev kho qhov ceev thiab lub sijhawm ntawm centrifugation, cov khoom tshwj xeeb tuaj yeem raug cais tawm, muab rau cov kws tshawb fawb thiab cov lag luam nrog kev tswj hwm meej ntawm lawv qhov kev sib cais xav tau.
3.3 Kev nthuav dav:
