Pipette yog siv hloov cov kev daws teeb meem, yog li nws yog ib qho tseem ceeb uas nws xa cov ntim paub. Burette yog siv ntxiv titrant rau cov tshuaj titrated thiab nws muaj qhov ntsuas ntawm sab, kom koj tuaj yeem ntsuas qhov ntim ntawm cov tshuaj ntxiv.
Ua li no, vim li cas lub pipette siv los ntsuas lub tog raj kheej?
A ntsuas lub tog raj kheej tsis yog ze li qhov tseeb li ib pipette . Qhov nqaim ntawm lub caj dab ntawm pipette thiab kev tsim khoom ntawm nws nrog cov kab meej kom nws muab cov ntim ntau dua xa tuaj. Tsis tas li ntawd, cov tee dej sab laug clinging hauv lub ntsuas lub tog raj kheej yog ntsuas tab sis tsis yog siv hauv cov tshuaj tiv thaiv.
Dab tsi yog kev siv lub pipette? Los thauj ib lub ntim ntsuas ntawm cov kua
Ntxiv mus, vim li cas tus pipette thiaj raug?
Volumetric pipets yog li ntawd raug vim tias lub caj dab ntev txo qhov ua yuam kev hauv kev ntsuas ntim ntawm meniscus. Lawv tsuas yog tsim los ntsuas ib lub ntim tshwj xeeb thiab feem ntau tuaj hauv qhov ntau thiab tsawg 5 mL, 10 mL, 25 mL, thiab 50 mL.
