lub centrifuge yog ib qho cuab yeej siv hauv chav kuaj uas cais cov khoom sib cais

Lub centrifuge yog ib lub cuab yeej siv hauv chav kuaj uas cais ntau yam khoom raws li lawv qhov ceev thiab qhov loj ntawm cov khoom me me. Nrog nws lub tshuab tig, lub centrifuge siv lub zog centrifugal rau cov qauv, ua rau cov khoom hnyav dua txav mus rau hauv qab ntawm cov raj lossis cov phaj thaum cov khoom sib dua nce mus rau saum. Lub cuab yeej no pom muaj ntau daim ntawv thov hauv kev tshawb fawb, kev kuaj mob hauv tsev kho mob, thiab cov chaw kuaj mob hauv kev lag luam. Hauv tsab xov xwm no, peb yuav tshawb nrhiav lub hauv paus ntsiab lus ua haujlwm ntawm lub centrifuge, nws cov hom sib txawv, cov kev xav tseem ceeb thaum siv ib qho, cov ntawv thov tseem ceeb, thiab kev nce qib hauv kev siv tshuab centrifugation.

I. Txoj Cai Ua Haujlwm ntawm Centrifuge

A. Kev Tsim Lub Zog Centrifugal

Cov centrifuges ua haujlwm raws li lub hauv paus ntsiab lus ntawm lub zog centrifugal, uas yog lub zog sab nraud uas ib yam khoom txav mus rau hauv txoj kev nkhaus. Thaum lub rotor tig sai sai, nws tsim lub zog centrifugal uas thawb cov qauv tawm ntawm lub rotor axis.

B. Txoj Kev Sib Cais

Qhov kev sib cais hauv lub centrifuge tshwm sim vim yog qhov sib txawv ntawm qhov ceev lossis qhov loj ntawm cov khoom me me. Cov khoom me me hnyav dua yuav poob rau hauv qab thaum lawv raug lub zog centrifugal siab dua, ua rau cov pellet lossis cov av qias neeg. Lub sijhawm no, cov khoom me me lossis cov khoom sib dua ntab rau saum toj, tsim cov supernatant.

II. Hom Centrifuges

A. Cov Tshuab Centrifuge Me Me

Cov tshuab centrifuge me me yog cov tshuab centrifuge me me uas tsim los rau cov qauv me me. Cov no feem ntau siv rau hauv kev tshawb fawb txog molecular biology, biochemistry, thiab kev tshawb fawb hauv chaw kho mob.

B. Cov Tshuab Centrifuges Loj

Cov tshuab centrifuges loj yog cov cuab yeej siv ceev ceev uas tig ntawm RPMs siab heev, tsim cov zog centrifugal siab. Lawv tso cai rau kev sib cais cov khoom me me uas muaj qhov ceev zoo sib xws, xws li kev sib cais ntawm cov organelles hauv lub cev.

C. Cov Qauv Centrifuges Hauv Pem Teb

Cov centrifuges qauv hauv pem teb yog cov cuab yeej loj dua thiab muaj zog dua uas feem ntau siv rau hauv cov chaw lag luam, cov chaw kuaj tshuaj, lossis cov txhab ntshav. Cov no muaj peev xwm ua cov ntim ntau dua thiab tuav cov khoom ntau dua.

III. Cov Kev Xav Tseem Ceeb Thaum Siv Lub Centrifuge

A. Lub rotor centrifuge

Xaiv lub rotor kom raug yog qhov tseem ceeb kom ua tiav kev sib cais kom raug. Hom rotor thiab lub peev xwm yuav tsum tau xaiv kom zoo raws li qhov ntim ntawm cov qauv, qhov loj me, thiab cov kev xav tau tshwj xeeb ntawm kev siv.

B. Kev Ceev thiab Kev Ua Kom Sai

Yuav tsum teeb tsa qhov ceev thiab kev nrawm kom tsim nyog kom ntseeg tau tias kev sib cais zoo yam tsis ua rau cov qauv lossis cov cuab yeej puas tsuaj. Cov xwm txheej centrifuging sib txawv nyob ntawm hom qauv thiab qhov tshwm sim xav tau.

C. Kev Sib Npaug Cov Qauv

Kev sib npaug ntawm cov qauv kuaj hauv lub rotor centrifuge ua kom muaj kev faib tawm sib npaug ntawm cov pawg, txo qhov kev pheej hmoo ntawm rotor co thaum lub sijhawm ua haujlwm. Cov qauv kuaj tsis sib npaug tuaj yeem ua rau kev sib cais tsis zoo thiab tuaj yeem ua rau lub centrifuge puas tsuaj.

IV. Cov Kev Siv Tseem Ceeb ntawm Centrifugation

A. Kev Cais Ntshav

Cov tshuab centrifuges siv dav hauv cov tsev txhab ntshav thiab cov chaw kuaj mob rau kev cais cov ntshav tag nrho ua nws cov khoom - cov qe ntshav liab, cov qe ntshav dawb, thiab cov plasma, uas tso cai rau kev kuaj mob thiab kho mob.

B. Kev Rho Tawm DNA thiab RNA

Kev centrifugation ua lub luag haujlwm tseem ceeb hauv kev rho tawm cov nucleic acids (DNA thiab RNA) los ntawm cov qauv tshuaj lom neeg. Nws pab cais cov khoom sib xyaw hauv lub cev, xws li cov protein, lipids, thiab nucleic acids, kom ua rau muaj kev tshuaj xyuas thiab kev tshawb fawb ntxiv.

C. Kev Tso Cov Khoom Me Me

Kev siv centrifugation hauv ntau yam lag luam, xws li tshuaj, los cais cov khoom khov thiab cov kua dej. Cov txheej txheem no pab kom tau cov khoom ntshiab, tshem tawm cov khoom tsis huv, thiab xyuas kom meej tias cov khoom kawg zoo.

V. Kev Nce Qib Hauv Kev Siv Tshuab Centrifugation

A. Kev Siv Microfluidic Centrifugation

Cov kws tshawb nrhiav tab tom tshawb nrhiav cov platform microfluidic rau cov tshuab centrifugation me me. Cov khoom siv no muaj cov txiaj ntsig xws li txo qhov yuav tsum tau muaj cov qauv ntau npaum li cas, lub sijhawm ua haujlwm luv dua, thiab muaj peev xwm koom ua ke nrog lwm cov haujlwm hauv chav kuaj.

B. Cov Txheej Txheem Tswj Xyuas Txawj Ntse

Cov tshuab centrifuge niaj hnub no muaj cov tshuab tswj ntse uas ua kom muaj kev nyab xeeb, kho ntau yam kev teeb tsa, thiab saib xyuas cov txheej txheem centrifugation tiag tiag. Cov kev nce qib no ua rau muaj kev raug, kev rov ua dua tshiab, thiab kev yooj yim rau cov neeg siv.

Xaus lus, cov centrifuges ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw tshawb fawb thiab kev lag luam. Lawv lub peev xwm los cais cov khoom raws li lawv qhov ceev thiab qhov loj me ua rau muaj ntau yam kev siv, txij li kev khaws cov ntshav mus rau kev rho tawm DNA thiab kev tso cov khoom me me. Nrog rau kev nce qib tas mus li hauv thev naus laus zis, cov txheej txheem centrifugation tau ua haujlwm zoo dua, meej dua, thiab yooj yim rau cov neeg siv. Raws li kev tshawb fawb thiab kev tsim kho tshiab nce qib, lub centrifuge yuav tseem yog lub cuab yeej tseem ceeb hauv cov chaw soj nstuam thoob ntiaj teb.
