Lub tshuab centrifuge yog dab tsi?
Kev Taw Qhia
Lub tshuab centrifuge yog ib qho khoom siv tseem ceeb uas siv rau hauv ntau yam lag luam thiab chaw kuaj mob. Nws siv lub hauv paus ntsiab lus ntawm centrifugation los cais cov khoom sib txawv ntawm qhov sib txawv hauv cov kua lossis roj sib tov. Cov txheej txheem no vam khom rau kev tsim lub zog centrifugal, uas ua rau cov khoom me me txav mus rau sab nraud, thaum cov khoom sib dua nyob ze rau hauv nruab nrab. Hauv tsab xov xwm no, peb yuav nkag mus tob dua rau hauv lub tshuab centrifuge, tshawb nrhiav nws txoj hauv kev ua haujlwm, kev siv, hom, thiab cov khoom tseem ceeb.
Nkag Siab Txog Txoj Cai Ua Haujlwm
Lub tshuab centrifuge yog ib qho kev tsim kho tshiab zoo kawg nkaus uas siv cov zog ua rau ib yam khoom tig. Nws siv qhov zoo ntawm lub zog centrifugal, uas tawm tsam lub zog gravitational, ua rau muaj kev sib cais ntawm ntau yam khoom. Lub tshuab muaj lub nruas tig ceev ceev, hu ua rotor, uas tuav cov qauv kom raug centrifuged. Thaum lub rotor tig sai sai, lub zog centripetal raug tsim, thawb cov khoom me me mus rau ntug sab nraud ntawm lub rotor thaum tsim kom muaj qhov sib txawv ntawm cov khoom me me.
Cov ntawv thov hauv Biotechnology thiab Medical Sciences
1. Kev Tshuaj Xyuas Cov Qauv Ntshav
Ib qho kev siv tseem ceeb ntawm kev siv centrifugation yog nyob rau hauv kev tshuaj xyuas cov qauv ntshav. Nws ua lub luag haujlwm tseem ceeb hauv kev cais cov khoom ntawm cov ntshav, xws li cov qe ntshav liab, cov qe ntshav dawb, cov platelets, thiab cov plasma. Los ntawm kev tig cov qauv ntshav hauv lub centrifuge, cov qe ntshav ntom dua raug cais tawm ntawm cov plasma, ua rau kev kuaj mob hauv chaw kuaj mob yooj yim dua thiab tso cai rau kev tshuaj xyuas ntau yam ntawm ntau yam kev ntsuas.
2. Kev ntxuav cov tshuaj lom neeg
Kev siv centrifugation dav dav hauv kev ntxuav cov tshuaj lom neeg. Piv txwv li, hauv kev rho tawm DNA, centrifugation ua kom zoo cais DNA ntawm lwm cov khoom hauv lub cev, xws li cov protein thiab nucleic acids. Ntxiv mus, centrifuges siv los ntxuav cov protein thiab cais cov organelles tshwj xeeb los ntawm cov cellular homogenates, pab txhawb kev tshawb fawb ntsig txog cell biology thiab molecular biology.
Hom Tshuab Centrifuge
1. Lub Centrifuge Rotor Ruaj Khoov
Lub tshuab centrifuge rotor uas muaj lub kaum sab xis ruaj khov yog ib hom tshuab centrifuge uas siv ntau. Nws muaj lub rotor uas nyob ntawm lub kaum sab xis ruaj khov, feem ntau ntawm 20 txog 40 degrees. Tus qauv rotor no tso cai rau kev sib cais cov khoom me me sai sai vim yog lub zog centrifugal ua rau perpendicular rau ntawm qhov chaw ntawm cov raj kuaj. Cov centrifuge rotor uas muaj lub kaum sab xis ruaj khov feem ntau siv thaum ua cov ntim me me.
2. Lub tshuab Centrifuge Rotor Swing-bucket
Lub tshuab centrifuge swing-bucket rotor yog lwm hom uas siv dav hauv cov chaw kuaj mob. Nws muaj lub rotor nrog cov khoom siv zoo li lub thoob uas tig tawm thaum lub sijhawm ua kom nrawm dua, ua rau cov raj kuaj mob nyob ntawm lub kaum sab xis. Qhov kev tsim no ua rau yooj yim rau kev tuav cov qauv thiab txo qhov muaj feem ntawm kev sib kis kab mob. Lub tshuab centrifuge swing-bucket rotor yog qhov tsim nyog rau cov qauv loj dua thiab feem ntau pom muaj nyob rau hauv cov chaw kuaj mob.
Cov Cheebtsam Tseem Ceeb ntawm Lub Tshuab Centrifuge
1. Lub rotor
Lub rotor yog ib qho tseem ceeb ntawm txhua lub tshuab centrifuge. Nws yog ib lub cylindrical qauv uas muaj peev xwm tig tau ceev heev. Hom rotor siv nyob ntawm seb daim ntawv thov thiab qhov yuav tsum tau ntim cov qauv. Cov rotors tuaj yeem yog lub kaum sab xis, lub thoob swing, ntsug, lossis kab rov tav, nrog txhua tus tsim los rau cov hom qauv tshwj xeeb.
2. Lub cev tsav tsheb
Lub tshuab tsav ntawm lub tshuab centrifuge hloov lub cev muaj zog txoj kev tig mus rau hauv qhov kev sib hloov ceev ceev uas xav tau rau centrifugation. Nws feem ntau muaj lub cev muaj zog, txoj siv tsav, thiab pulleys. Lub cev muaj zog tsav lub rotor los ntawm kev sib txuas tshuab, ua kom ntseeg tau tias qhov kev sib hloov ceev tas mus li thiab txhim khu kev qha thaum lub sijhawm sib cais.
3. Vaj Huam Sib Luag
Cov tshuab centrifuge muaj cov vaj huam sib luag tswj uas tso cai rau cov neeg siv teeb tsa thiab tswj ntau yam kev teeb tsa. Cov vaj huam sib luag no feem ntau muaj cov chaw teeb tsa rau qhov ceev, lub sijhawm, kub, thiab kev nrawm thiab qeeb. Cov qauv siab heev kuj tseem yuav suav nrog cov kev pab cuam uas tau teeb tsa ua ntej thiab cov yam ntxwv kev nyab xeeb, xws li lub hau xauv thiab cov txheej txheem kuaj xyuas qhov tsis sib npaug.
4. Cov yam ntxwv kev nyab xeeb
Cov tshuab centrifuge muaj ntau yam kev nyab xeeb los tiv thaiv cov neeg siv thiab cov qauv kuaj. Cov no suav nrog lub hau xauv uas tiv thaiv kev qhib tsis tau thaum lub sijhawm ua haujlwm, cov tshuab kuaj tsis sib npaug uas yuav nres lub tshuab tam sim ntawd yog tias qhov khoom tsis sib npaug, thiab cov nyees khawm nres thaum muaj xwm txheej ceev rau kev kaw tam sim ntawd.
