Kev Taw Qhia Txog Centrifuges: Ib Daim Ntawv Qhia Luv Luv
Hauv ntiaj teb kev tshawb fawb thiab kev lag luam, lub tshuab zoo kawg nkaus hu ua centrifuge tau dhau los ua ib qho cuab yeej tseem ceeb rau ntau yam kev siv. Txij li cov chaw soj ntsuam mus rau cov chaw tsim khoom, centrifuges muab txoj hauv kev tshwj xeeb rau kev sib cais cov khoom sib xyaw, cais cov khoom me me, thiab tshuaj xyuas cov tshuaj. Hauv tsab xov xwm no, peb yuav tshawb nrhiav kev ua haujlwm, kev siv, thiab kev cuam tshuam ntawm centrifuges rau ntau qhov chaw.
Kev Ua Haujlwm thiab Daim Ntawv Thov ntawm Centrifuges
Cov centrifuges ua haujlwm raws li lub hauv paus ntsiab lus ntawm lub zog centrifugal, uas tso cai rau kev sib cais cov khoom uas muaj ntau qhov sib txawv lossis qhov loj me. Los ntawm kev tig cov qauv ntawm qhov ceev ceev, centrifuges ua rau muaj kev sib cais ntawm cov khoom khov thiab cov kua lossis kev sib cais ntawm cov khoom sib txawv hauv kev sib tov. Qhov kev ua haujlwm no ua rau nws yog ib qho cuab yeej tseem ceeb hauv ntau yam kev tshawb fawb thiab kev lag luam.
Ntau yam kev lag luam tau txais txiaj ntsig los ntawm kev ua haujlwm ntawm cov centrifuges. Hauv kev tshawb fawb txog kev tshawb fawb, cov tshuab no pom cov ntawv thov hauv biochemistry, molecular biology, microbiology, thiab kev kuaj mob. Hauv kev kho mob, lawv feem ntau siv hauv cov txhab ntshav, tsev kho mob, thiab cov chaw soj nstuam tshuaj. Tsis tas li ntawd, cov lag luam xws li khoom noj thiab dej haus, roj thiab roj av, thiab kev kho dej khib nyiab vam khom cov centrifuges rau kev tsim khoom zoo, kev tswj xyuas zoo, thiab kev ntsuas kev nyab xeeb.
Saib Xyuas Zoo Dua ntawm Cov Hom Centrifuges
Cov centrifuges muaj ntau yam qauv tsim thiab kev teeb tsa uas tsim los rau cov kev siv tshwj xeeb. Cov hom feem ntau suav nrog cov centrifuges saum rooj, cov centrifuges sawv hauv pem teb, ultracentrifuges, thiab cov centrifuges txias.
Cov tshuab centrifuges uas siv rau saum rooj yog cov me me, pheej yig, thiab feem ntau pom muaj nyob rau hauv cov chaw kuaj mob me me lossis cov chaw kho mob. Lawv tsim nyog rau kev sib cais qhov ceev qis mus rau nruab nrab thiab tuaj yeem ntim ntau lub raj kuaj tib lub sijhawm.
Cov tshuab centrifuges uas sawv hauv pem teb, ntawm qhov tod tes, loj dua thiab muaj zog dua. Lawv tuaj yeem tswj cov qauv ntau dua thiab ua tiav qhov ceev dua, ua rau cov txheej txheem sib cais sai dua.
Ultracentrifuges yog ib hom centrifuge siab heev uas muaj peev xwm tig cov qauv ntawm qhov ceev heev. Nrog rau qhov ceev txog li 100,000 revolutions ib feeb (RPM), cov khoom siv no ua rau kev sib cais cov khoom me me nrog qhov tseeb thiab kev daws teeb meem zoo heev.
Cov centrifuges uas tau txias hauv lub tub yees muaj peev xwm ua kom txias, uas tso cai rau kev sib cais cov qauv uas rhiab heev rau qhov kub thiab txias. Los ntawm kev tswj hwm qhov kub thiab txias ib puag ncig, cov centrifuges no tiv thaiv kev puas tsuaj ntawm cov qauv thiab khaws cia qhov zoo ntawm cov qauv tsiaj txhu.
Yuav Ua Li Cas Centrifuges Txhim Kho Kev Tshawb Fawb thiab Kev Kho Mob
Cov centrifuges ua lub luag haujlwm tseem ceeb hauv kev tshawb fawb, tshwj xeeb tshaj yog hauv cov teb uas muaj kev kawm txog cov qauv cellular thiab biomolecules. Hauv biochemistry thiab molecular biology, centrifugation pab cais DNA, RNA, protein, thiab lwm yam khoom cellular. Los ntawm kev cais cov khoom no, cov kws tshawb fawb tuaj yeem tshuaj xyuas thiab nkag siab txog kev ua haujlwm ntawm cov kab mob biological, daws cov txheej txheem kab mob, thiab tsim cov txheej txheem kho mob siab heev.
Hauv kev kuaj mob hauv tsev kho mob thiab cov chaw kuaj mob, cov centrifuges yog qhov tseem ceeb rau kev kuaj mob niaj hnub, xws li suav cov qe ntshav, kev tshuaj xyuas serum, thiab kev sib cais plasma. Lawv tso cai rau kev kuaj mob, kev kuaj mob, thiab kev saib xyuas ntau yam mob, suav nrog kev kis kab mob, ntshav tsis txaus, thiab kab mob siab.
Kev siv centrifugation kuj tseem ceeb heev rau kev tshawb fawb thiab kev txhim kho tshuaj. Los ntawm kev sib cais thiab ntxuav cov tshuaj sib xyaw, cov kws tshawb fawb tuaj yeem soj ntsuam lawv qhov ua tau zoo, soj ntsuam cov kev mob tshwm sim, thiab ua kom zoo dua cov tshuaj. Qhov no ua kom ntseeg tau tias muaj kev tsim cov tshuaj muaj kev nyab xeeb thiab ua haujlwm tau zoo.
