Kev Taw Qhia Txog Centrifugation thiab Nws Qhov Tseem Ceeb Hauv Cov Txheej Txheem Sib Cais
Kev siv centrifugation yog ib txoj kev tseem ceeb uas siv rau ntau yam kev tshawb fawb, suav nrog chemistry, biology, thiab tshuaj, rau kev sib cais cov khoom khov lossis cov kua sib xyaw. Txoj kev muaj zog thiab ua haujlwm tau zoo no siv cov ntsiab cai ntawm lub zog centrifugal los ua kom sib cais. Hauv tsab xov xwm no, peb yuav kawm tob dua txog lub tshuab ua haujlwm tom qab lub centrifuge thiab tshawb nrhiav nws qhov tseem ceeb hauv cov txheej txheem sib cais.
Nkag Siab Txog Kev Tsim thiab Cov Cheebtsam ntawm Centrifuge
Feem ntau lub tshuab centrifuge muaj lub rotor uas tsav los ntawm lub cev muaj zog, lub thawv rau cov qauv, thiab lub hau lossis lub hau kom ntseeg tau tias tus neeg teb xov tooj muaj kev nyab xeeb. Lub rotor yog qhov tseem ceeb uas ua rau muaj lub zog centrifugal. Nws tig ntawm qhov ceev ceev, feem ntau yog ntau txhiab lub revolutions ib feeb (RPM), muab lub zog tsim nyog rau kev tso dej lossis kev sib cais.
Lub Luag Haujlwm ntawm Lub Zog Centrifugal hauv Kev Sib Cais
Lub zog centrifugal yog lub zog pom tseeb uas ua rau cov khoom txav mus los hauv txoj kev voj voog. Thaum muab ib qho sib tov tso rau hauv lub rotor tig, qhov khoom sib xyaw uas ntom tshaj plaws hauv qhov sib tov txav mus rau ntug sab nraud vim yog qhov thawb sab nraud los ntawm lub zog centrifugal. Lub caij no, cov khoom sib xyaw sib dua txav mus rau hauv nruab nrab, tsim cov khaubncaws sab nraud sib txawv.
Hom Centrifuges thiab Lawv Cov Ntawv Thov
Muaj ntau hom centrifuges muaj, txhua hom haum rau cov txheej txheem sib cais thiab cov qauv kuaj sib txawv. Qee hom uas siv ntau suav nrog differential centrifuges, preparative centrifuges, ultracentrifuges, thiab analytical ultracentrifuges. Differential centrifuges siv dav hauv cov chaw kuaj mob rau kev tso cov ntshav kuaj, thaum preparative centrifuges siv rau kev cais cov khoom tshwj xeeb hauv ntau qhov ntau.
Ntawm qhov tod tes, Ultracentrifuges tuaj yeem ua tiav qhov ceev heev thiab siv rau hauv kev tshawb fawb xws li biochemistry thiab molecular biology. Cov tshuab muaj zog heev no tuaj yeem ntsuas qhov sib txawv me me ntawm qhov hnyav molecular thiab pab cov kws tshawb fawb kawm macromolecules nrog qhov tseeb siab. Analytical ultracentrifuges tau nruab nrog cov tshuab optical uas ua rau muaj kev tshuaj xyuas lub sijhawm tiag tiag ntawm cov nqi sedimentation, pab txhawb kev kawm ntxaws ntxaws ntawm kev sib cuam tshuam macromolecular thiab kev hloov pauv conformational.
Kev Txhim Kho Cov Txheej Txheem Ua Haujlwm thiab Kev Ua Haujlwm Zoo
Yuav siv lub centrifuge los cais cov khoom no, ua ntej yuav muab cov khoom no ntxiv rau hauv cov raj lossis cov thawv uas tsim los kom haum rau hauv lub rotor. Tom qab kaw lub hau lawm, lub centrifuge yuav raug teeb tsa kom raws li qhov ceev thiab lub sijhawm uas xav tau. Thaum lub rotor tig, cov khoom hnyav lossis cov khoom sib xyaw hauv cov khoom sib xyaw yuav pib poob rau hauv qab, ua ib lub pellet. Tib lub sijhawm, cov khoom sib xyaw uas sib dua yuav tsim cov khaubncaws sab nraud povtseg saum lub pellet raws li lawv qhov ceev.
Cov kev txhim kho kev ua haujlwm tau siv rau hauv cov centrifuges niaj hnub no los txhim kho cov txiaj ntsig kev sib cais. Cov no suav nrog cov qauv rotor uas ruaj khov thiab ruaj ntseg, cov txheej txheem tswj hwm siab heev rau kev ceev thiab lub sijhawm tseeb, thiab lub peev xwm los ua kom cov txheej txheem ua haujlwm tau zoo dua, txo qis kev ua yuam kev ntawm tib neeg thiab ua kom muaj kev ua haujlwm zoo dua.
Cov Kev Siv Centrifugation Hauv Cov Kev Tshawb Fawb Sib Txawv
Kev siv centrifugation pom muaj ntau yam kev siv hauv ntau qhov chaw tshawb fawb. Hauv kev tshawb fawb txog biomedical, centrifugation yog siv los cais DNA, RNA, thiab cov protein los ntawm cov qauv. Nws ua rau muaj kev sib cais ntawm cov khoom sib txawv ntawm tes, xws li mitochondria lossis nuclei. Hauv kev lag luam tshuaj, centrifugation ua lub luag haujlwm tseem ceeb hauv kev rho tawm thiab kev ntxuav ntawm ntau yam tshuaj thaum lub sijhawm tsim tshuaj.
Hauv kev tshawb fawb txog ib puag ncig, kev siv centrifugation pab rho tawm thiab tshuaj xyuas cov kuab paug los ntawm cov qauv dej thiab av. Nws kuj yog ib txoj hauv kev tseem ceeb hauv kev tsim cov roj biofuels, qhov twg nws pab cais cov roj lossis ethanol ntawm biomass. Tsis tas li ntawd, kev siv centrifugation siv rau hauv kev lag luam khoom noj thiab dej haus rau kev cais cov khoom khov ntawm cov kua lossis sib txawv cov kua ntom rau lub hom phiaj tswj xyuas zoo.
Xaus lus, centrifugation yog ib txoj kev sib cais muaj zog uas siv dav hauv kev tshawb fawb uas xav tau kev cais thiab kev ntxuav cov khoom sib xyaw. Nrog ntau hom centrifuges siv niaj hnub no thiab kev nce qib tas mus li hauv thev naus laus zis, qhov ua tau zoo thiab qhov tseeb ntawm kev sib cais ua tiav txuas ntxiv mus, ua rau muaj kev tshawb fawb thiab kev tsim kho tshiab thoob plaws ntau yam lag luam.
