tuaj yeem tsis yaj.precipitates raug sib cais los ntawm centrifuge
Tsab xov xwm:
Kev Taw Qhia:
Kev siv centrifugation yog ib txoj kev siv dav hauv ntau yam lag luam, suav nrog kev lag luam tshuaj, biotechnology, thiab chemistry. Nws cuam tshuam nrog kev sib cais cov khoom sib xyaw hauv cov khoom sib xyaw raws li lawv qhov sib txawv ntawm qhov ceev. Ib lo lus nug txaus nyiam uas tshwm sim yog seb cov precipitates tsis yaj puas tuaj yeem sib cais tau zoo siv lub centrifuge. Hauv tsab xov xwm no, peb yuav tshawb nrhiav cov peev xwm thiab cov kev txwv ntawm centrifugation rau kev sib cais cov precipitates tsis yaj.
1. Kev Nkag Siab Txog Cov Dej Uas Tsis Yaj Tau:
Yuav kom nkag siab seb cov dej khov uas tsis yaj puas tuaj yeem sib cais los ntawm lub centrifuge, nws yog ib qho tseem ceeb ua ntej kom nkag siab tias cov dej khov no yog dab tsi. Cov dej khov uas tsis yaj yog cov khoom khov uas tsim thaum ob lossis ntau cov tshuaj yaj sib xyaw ua ke. Cov khoom no tsis yaj hauv cov kuab tshuaj thiab feem ntau nyob hauv qab ntawm lub thawv. Kev sib cais lawv ntawm cov kua dej tuaj yeem nyuaj yam tsis siv cov txheej txheem tshwj xeeb xws li centrifugation.
2. Lub Ntsiab Cai ntawm Centrifugation:
Kev siv lub tshuab centrifugation siv lub hauv paus ntsiab lus ntawm kev tso dej tawm, qhov twg cov khoom me me hauv cov kua sib tov feem ntau yuav poob vim yog lub ntiajteb txawj nqus. Lub tshuab centrifuge ua kom cov txheej txheem no nrawm dua los ntawm kev siv lub zog centrifugal, uas tsav cov khoom me me mus rau ntawm phab ntsa ntawm lub raj centrifuge. Lub zog siv nyob ntawm qhov ceev tig thiab lub vojvoog ntawm lub rotor centrifuge. Siv cov txheej txheem no, cov tshuaj tuaj yeem sib cais raws li lawv qhov sib txawv ntawm qhov ceev. Txawm li cas los xij, cov dej nag uas tsis yaj tau muaj cov yam ntxwv tshwj xeeb uas tuaj yeem ua rau muaj kev cov nyom hauv lawv txoj kev sib cais.
3. Cov Teeb Meem Hauv Kev Cais Cov Dej Uas Tsis Yaj Tau:
Kev cais cov dej nag uas tsis yaj los ntawm kev siv centrifugation yuav ntsib ob peb qhov teeb meem. Ua ntej, cov dej nag feem ntau muaj qhov ceev ceev ntawm kev sib sau ua ke, uas ua rau nws nyuaj rau lub centrifuge siv zog txaus los tiv thaiv lawv cov dej nag. Tsis tas li ntawd, qhov loj thiab cov duab ntawm cov dej nag tuaj yeem cuam tshuam rau qhov ua tau zoo ntawm cov txheej txheem centrifugation. Cov dej nag loj thiab tsis sib xws yuav tsis sib cais zoo, ua rau muaj qhov tshwm sim tsis zoo. Tsis tas li ntawd, qee cov dej nag tuaj yeem tsim cov pob zeb, ua rau lawv sib cais nyuaj dua los ntawm centrifugation.
4. Kev Txhim Kho Kom Zoo Dua Rau Kev Sib Cais Zoo:
Txawm hais tias muaj kev cov nyom los xij, muaj ntau txoj kev siv tau los ua kom zoo tshaj plaws ntawm kev sib cais cov dej nag uas tsis yaj tau los ntawm kev siv lub tshuab centrifuge. Ib txoj kev siv no yog kev ntxiv cov neeg sawv cev flocculating lossis coagulants. Cov tshuaj no pab txhawb kev sib sau ua ke ntawm cov khoom me me ntawm cov dej nag mus rau hauv cov pawg loj dua thiab yooj yim sib cais dua. Los ntawm kev tsim cov pob loj dua, cov dej nag yuav tsis yooj yim rov ua dua thaum lub sijhawm centrifugation, yog li txhim kho kev sib cais zoo.
5. Hom Centrifuges rau Kev Sib Cais Precipitate:
Cov centrifuges sib txawv siv tau rau kev cais cov dej nag uas tsis yaj, tshwj xeeb tshaj yog nyob ntawm qhov ntim thiab cov yam ntxwv ntawm cov qauv. Cov centrifuges ceev ceev feem ntau siv rau hauv cov chaw soj nstuam uas cov qauv me me raug ua tiav. Cov centrifuges no tuaj yeem ua tiav qhov ceev ceev dua, ua rau muaj zog centrifugal rau kev sib cais zoo. Ntawm qhov tod tes, cov txheej txheem kev lag luam loj dua tuaj yeem siv cov centrifuges txuas ntxiv mus, uas muab cov khoom siv ntau dua thiab muaj peev xwm nthuav dav zoo dua.
Xaus lus:
Xaus lus, thaum kev sib cais cov precipitates uas tsis yaj tau tuaj yeem nyuaj, centrifugation tuaj yeem yog ib txoj hauv kev muaj txiaj ntsig zoo rau lawv kev sib cais hauv qab qhov xwm txheej tsim nyog. Cov yam xws li qhov ceev ntawm kev sib sau ua ke, qhov loj me ntawm cov khoom me me, thiab cov duab ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov ua tiav ntawm cov txheej txheem sib cais. Los ntawm cov txheej txheem kev ua kom zoo dua xws li flocculation thiab siv hom centrifuge zoo, cov precipitates uas tsis yaj tau tuaj yeem sib cais tau zoo, ua rau ntau yam lag luam tuaj yeem ua kom lawv cov txheej txheem yooj yim dua thiab txhim kho cov khoom zoo.
