lub centrifuge ua haujlwm li cas los cais cov ntshav
Lub tshuab centrifuge yog ib yam khoom siv tseem ceeb hauv chav kuaj mob uas siv dav hauv ntau qhov chaw tshawb fawb thiab kho mob. Ib qho ntawm nws cov kev siv tseem ceeb yog kev cais cov ntshav rau kev kuaj mob thiab kev tshawb fawb. Hauv tsab xov xwm no, peb yuav tshawb nrhiav seb lub tshuab centrifuge ua haujlwm li cas los cais cov ntshav thiab ntau yam uas ua rau nws ua haujlwm tau zoo.
Kev Nkag Siab Txog Cov Ntshav
Ua ntej yuav nkag siab txog cov txheej txheem ntawm lub centrifuge, nws yog ib qho tseem ceeb kom nkag siab txog cov ntshav. Cov ntshav feem ntau muaj cov qe ntshav liab (erythrocytes), cov qe ntshav dawb (leukocytes), platelets (thrombocytes), thiab plasma. Txhua yam khoom muaj lub luag haujlwm tshwj xeeb hauv kev tswj hwm kev noj qab haus huv ntawm lub cev.
1. Lub Hom Phiaj ntawm Kev Cais Ntshav
Kev cais cov ntshav yog qhov tseem ceeb rau ntau yam kev kho mob thiab kev tshawb nrhiav hauv chav kuaj mob. Los ntawm kev cais cov khoom tshwj xeeb ntawm cov ntshav, cov kws tshawb fawb thiab cov kws kho mob tuaj yeem tau txais kev nkag siab zoo txog cov kab mob, ua kev kuaj mob, thiab tsim cov kev kho mob tshiab. Tsis tas li ntawd, kev cais cov ntshav tso cai rau kev sau cov khoom xws li plasma lossis platelets, uas tuaj yeem siv rau ntau yam kev kho mob.
Lub hauv paus ntsiab lus ua haujlwm ntawm lub centrifuge
Lub zog centrifugal yog lub hauv paus ntawm kev ua haujlwm ntawm lub centrifuge. Lub zog no ua haujlwm tawm ntawm qhov chaw nruab nrab ntawm kev tig thiab ua rau cov khoom me me hauv cov qauv txav mus rau sab nraud thaum cov khoom me me txav mus rau qhov chaw nruab nrab. Lub hauv paus ntsiab lus no ua rau muaj kev sib cais ntawm cov khoom ntshav raws li lawv qhov sib txawv ntawm qhov ceev.
2. Lub zog centrifugal: Centripetal thiab Centrifugal Acceleration
Lub zog centrifugal feem ntau raug suav tias yog lub zog tiag tiag. Qhov tseeb, nws yog los ntawm kev nrawm ntawm centripetal, uas yog lub zog uas coj mus rau sab hauv ua rau muaj kev txav mus los (piv txwv li, kev tig ntawm lub rotor centrifuge). Kev nrawm ntawm centrifugal yog lub zog pseudo-force uas cov khoom me me hauv lub cev tig mus los thawb lawv mus rau sab nraud. Los ntawm kev sib npaug ntawm ob lub zog no, lub centrifuge tsim kom muaj kev sib cais xav tau.
Hom Centrifuges
Muaj ntau hom centrifuges muaj, suav nrog microcentrifuges, benchtop centrifuges, high-speed centrifuges, thiab ultracentrifuges. Txhua hom sib txawv ntawm qhov ceev tig, peev xwm, thiab kev siv. Ultracentrifuges, muaj peev xwm ncav cuag qhov ceev tshaj plaws, tshwj xeeb tshaj yog pab tau rau kev sib cais ntshav vim lawv muaj peev xwm cais txawm tias cov khoom me me tshaj plaws tau zoo.
3. Kev Ceev thiab Lub Sijhawm Tig: Cov Yam Cuam Tshuam Rau Kev Sib Cais Ntshav
Qhov ceev thiab lub sijhawm tig yog cov yam ntxwv tseem ceeb uas cuam tshuam rau qhov ua tau zoo ntawm kev sib cais ntshav hauv lub centrifuge. Qhov ceev tig siab dua ua rau cov qauv raug rau lub zog centrifugal thiab centrifugal ntau dua, ua rau cov txheej txheem sib cais zoo dua. Txawm li cas los xij, qhov ceev siab dhau tuaj yeem ua rau cov khoom tawg yooj yim puas tsuaj, ua rau kev kho kom zoo dua qub tseem ceeb. Lub sijhawm yog lwm yam tseem ceeb, vim nws tso cai rau kev sib cais txaus, tshwj xeeb tshaj yog thaum muaj cov feem ntau, xws li cov qe ntshav liab, koom nrog.
Cov Hom Centrifuge Rotor
Cov rotors centrifuge tuav cov raj kuaj thaum lub sijhawm tig hauv lub centrifuge. Kev xaiv hom rotor nyob ntawm qhov yuav tsum tau ua ntawm txoj haujlwm cais ntshav. Cov rotors uas muaj lub kaum sab xis ruaj khov tso cov raj rau ntawm lub kaum sab xis ruaj khov thaum lub sijhawm tig, thaum cov rotors swinging-bucket txav cov raj mus rau hauv thiab tawm ntawm lub zog centrifugal thaum lawv tig.
4. Kev Xaiv Rotor: Ua Kom Zoo Tshaj Plaws Kev Sib Cais Ntshav
Kev xaiv lub rotor yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo tshaj plaws ntawm kev sib cais cov ntshav. Cov rotors uas muaj lub kaum sab xis feem ntau siv rau cov hom phiaj dav dav, thaum cov rotors swinging-bucket nyiam siv rau kev sib cais maj mam, vim tias lawv txo qhov kev pheej hmoo ntawm kev puas tsuaj rau cov khoom tawg yooj yim. Kev xaiv kom raug ua kom cov ntshav seem uas xav tau tseem sib cais, ua rau muaj kev tshuaj xyuas tseeb thiab kev siv tau zoo.
Cov Teeb Meem thiab Kev Ceev Faj hauv Kev Sib Cais Ntshav
Txawm hais tias kev siv centrifugation yog ib txoj kev siv zog rau kev sib cais cov ntshav, yuav tsum xav txog qee qhov kev cov nyom thiab kev ceev faj kom tau txais cov txiaj ntsig zoo. Ua ntej, qhov loj ntawm lub raj thiab hom kev xaiv yog qhov tseem ceeb kom tsis txhob muaj cov qauv xau, kev sib kis kab mob, thiab kev sib cais tsis raug. Qhov thib ob, kev tswj kom muaj qhov sib npaug zoo hauv lub centrifuge rotor yog qhov tseem ceeb kom txo qis kev co thiab tiv thaiv kev puas tsuaj ntawm rotor.
5. Kev Ceev Faj: Cov Txheej Txheem Kub thiab Centrifugation
Kev tswj qhov kub thaum lub sijhawm centrifugation yog qhov tseem ceeb rau kev khaws cia cov khoom ntawm cov ntshav kom zoo. Qhov kub heev tuaj yeem ua rau cov protein puas tsuaj thiab cuam tshuam rau qhov zoo ntawm cov feem uas tau sib cais. Ntxiv mus, kev ua raws li cov txheej txheem centrifugation uas tau lees paub tshwj xeeb rau cov txheej txheem sib cais ntshav yog qhov tseem ceeb kom tau txais cov txiaj ntsig zoo sib xws thiab xyuas kom meej tias cov kev sim lossis kev kuaj mob rov ua dua.
Xaus lus, kev nkag siab txog seb lub centrifuge ua haujlwm li cas los cais cov ntshav yog qhov tseem ceeb rau kev ua qhov kev kuaj mob, kev tshawb fawb, thiab cov txheej txheem kho mob kom raug. Los ntawm kev siv cov ntsiab cai ntawm lub zog centripetal thiab centrifugal, nrog rau kev xaiv rotor thiab cov txheej txheem ceev faj, centrifugation ua rau cov kws tshawb fawb thiab cov kws kho mob siv lub peev xwm loj heev ntawm cov khoom ntshav hauv lawv cov teb.
