A centrifuge yog ib qho cuab yeej uas cais cov khoom los ntawm kev daws los ntawm kev siv lub rotor. Ntawm ib qho ruaj centrifugal quab yuam thiab kua viscosity, lub sedimentation tus nqi ntawm ib tug particle yog proportional rau nws loj (molecular hnyav) thiab rau qhov sib txawv ntawm particle ntom thiab ntom ntawm cov tshuaj.
Ib yam li ntawd, nws raug nug, dab tsi yog sedimentation tus nqi hauv centrifugation?
Los ntawm Wikipedia, phau ntawv txhais lus pub dawb. Cov sedimentation coefficient (s) ntawm ib tug particle characterizes nws sedimentation thaum centrifugation . Nws yog txhais raws li qhov ratio ntawm ib tug particle's sedimentation velocity rau qhov kev siv acceleration ua rau lub sedimentation.
Qhov thib ob, lub centrifuge yog dab tsi thiab nws ua haujlwm li cas? A centrifuge yog ib qho cuab yeej uas tig cov qauv ua kua ntawm kev kub ceev thiab yog li tsim kom muaj zog centripetal quab yuam ua rau cov ntaub ntawv denser mus rau hauv qab ntawm lub centrifuge tube sai dua lawv yuav nyob rau hauv lub zog ntawm lub ntiajteb txawj nqus. Hom ntawm centrifuges.
Tsis tas li ntawd, txoj kev centrifugation yog dab tsi?
Centrifugation yog txheej txheem qhov twg sib tov yog sib cais los ntawm spinning. Nws yog siv los cais cov skim mis los ntawm tag nrho cov mis nyuj, dej los ntawm koj cov khaub ncaws, thiab cov qe ntshav los ntawm koj cov ntshav plasma.
Yuav ua li cas nyob rau hauv lub centrifuge?
Cov centrifuge ua haujlwm siv lub hauv paus ntsiab lus sedimentation, qhov twg centrifugal acceleration ua rau denser tshuaj thiab hais tawm mus rau sab nraud nyob rau hauv lub radial kev taw qhia. Nyob rau tib lub sijhawm, cov khoom uas tsis tshua muaj ntom ntom ntom ntom ntom nti thiab txav mus rau qhov chaw.
