A volumetric pipette , noob pib , los yog plab pib tso cai rau kev ntsuas qhov tseeb heev (rau plaub qhov tseem ceeb) ntawm qhov ntim ntawm kev daws teeb meem. Volumetric pipettes feem ntau siv nyob rau hauv analytical chemistry los ua cov kev daws teeb meem los ntawm lub hauv paus Tshuag nrog rau kev npaj cov kev daws rau titration.
Tsis tas li lo lus nug yog, dab tsi yog qhov volumetric pipette siv rau?
Volumetric Pipettes yog tsim los kom raug xa mus rau ib qho kev daws teeb meem. Cov no cev tuaj yeem yog siv rau xa cov ntim ntawm cov kua uas nws yog calibrated. Volumetric pipets muaj cov lus qhia nqaim thiab lub teeb zoo li nthuav dav hauv nruab nrab.
Ib tug kuj yuav nug, dab tsi yog qhov txawv ntawm ib tug pipette thiab ib tug dropper? Pasteur cov pipettes , kuj hu ua droppers yog siv los hloov cov kua me me, tab sis tsis kawm tiav. Pasteur cov pipettes yog ua los ntawm yas los yog iav. Mohr cov pipettes yog ntsuas cov pipettes uas zoo li serological cov pipettes , nrog lub hauv paus txawv tias cov kawm tiav tsis txuas mus rau qhov kawg.
Tsis tas li ntawd, lub pipette ntsuas dab tsi?
Txog Pipettes . A pib yog ib qho cuab yeej kuaj siv rau ntsuas tawm los yog hloov cov kua me me, hauv ntim ntawm milliliters (mL), microliters (ΜL).
Dab tsi yog qhov tseeb tshaj plaws ntawm pipette?
volumetric pipette
Pom zoo:
Thaum cov khoom siv dielectric ntxig rau ntawm daim hlau ntawm lub capacitor nws nce nws?
Thaum lub dielectric tag nrho muab tso rau ntawm ob daim hlau ntawm capacitor ces nws yog dielectric tas li nce los ntawm nws lub tshuab nqus tsev nqi. Yog li, thiab, yog qhov kev tso cai ntawm cov khoom
Hom pipette yog Ostwald thiab nws siv rau dab tsi?
Ostwald-Folin pipettes muaj qhov muag teeb ze rau qhov kev xa khoom tsis zoo li volumetric pipett uas muaj nyob hauv nruab nrab. Cov (OF) no yog siv los ntsuas qhov tseeb ntawm cov kua dej khov, xws li ntshav lossis ntshav. Volumetric pipet yog nws tus kheej draining thiab yog siv nyob rau hauv diluting qauv, calibrators, los yog zoo-tswj cov ntaub ntawv
Dab tsi yog DNA zoo li cuam tshuam nws cov qauv tshuaj rau nws zoo li cas thaum muaj ntau ntawm nws yog clumped ua ke?
Hais txog nws cov qauv tshuaj rau nws zoo li cas thaum ntau nws yog clumped ua ke. DNA zoo li kab laug sab webs. DNA tau soluble hauv DNA extraction tsis yog li peb tsis pom nws. Thaum nws tau stirred rau hauv ethanol, nws clumped ua ke thiab tsim thicker thiab thicker strands loj txaus kom pom
Dab tsi nthwv dej zoo li cov cuab yeej ntawm lub teeb ua rau nws hloov kev taw qhia thaum nws txav ntawm ib nrab mus rau lwm qhov?
Refraction
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
