"Raws li cov lus qhia tuaj yeem haum, nws yog lub tswv yim uas tuaj yeem siv tau"
—— Qhov no yog qhov kev nkag siab ntawm yuav luag txhua tus neeg siv txog kev hloov pauv ntawm cov lus qhia. Cov lus no yog ib feem muaj tseeb tab sis tsis muaj tseeb kiag li.
Cov lus qhia uas tuaj yeem txuas rau lub pipette tuaj yeem tsim ib qho kev sib txuas nrog lub pipette kom paub txog qhov kev ua haujlwm pipetting, tab sis qhov no puas ntseeg tau? Yuav tsum muaj ib lo lus nug ntawm no. Teb cov lus nug no yuav tsum tau cov ntaub ntawv hais lus rau nws tus kheej.
1. Koj tuaj yeem xav sim qhov kev ua tau zoo tom qab sib piv cov pipette nrog lub ntsis. Tom qab yaug lub ntsis, ua ob peb zaug ntxiv, ntsuas txhua qhov ntxiv, thiab sau cov ntawv nyeem.
2. Xam qhov tseeb thiab qhov tseeb ntawm kev ua haujlwm pipetting tom qab hloov qhov ntom ntawm cov kua ntsuas rau hauv ntim.
3. Qhov peb xav xaiv yog cov lus qhia nrog qhov tseeb zoo. Yog tias qhov sib piv qhov tseeb ntawm cov kav dej thiab cov lus qhia tsis zoo, nws txhais tau hais tias qhov nruj ntawm lub taub thiab lub pipette tsis tuaj yeem lav tau, ua rau cov txiaj ntsig ntawm txhua qhov kev ua haujlwm tsis tuaj yeem tsim.
Yog li dab tsi yuav tsum muaj lub taub hau nqus zoo yam tsawg kawg?
Lub tswv yim zoo nyob ntawm concentricity, taper, thiab tseem ceeb tshaj, adsorption;
1. Cia peb tham txog lub taper ua ntej: yog tias nws zoo dua, kev sib tw nrog rab phom yuav zoo heev, thiab qhov nqus yuav raug ntau dua;
2. Concentricity: Concentricity hais txog seb lub voj voog ntawm lub tshuab nqus tsev ntawm lub tshuab nqus tsev thiab qhov kev sib txuas ntawm lub taub hau nqus thiab lub pipette zoo li qhov nruab nrab ntawm lub voj voog. Yog hais tias nws tsis yog tib qhov chaw, nws txhais tau hais tias lub concentricity tsis zoo;
3. Thaum kawg, qhov tseem ceeb tshaj plaws yog peb qhov adsorption: qhov adsorption muaj feem xyuam rau cov khoom ntawm lub hau. Yog tias cov khoom siv ntawm lub taub hau tsis zoo, nws yuav cuam tshuam rau qhov tseeb ntawm pipetting, uas ua rau cov kua dej ntau los yog luv luv. Rau dai rau ntawm phab ntsa, uas ua rau pipetting yuam kev;
Yog li ntawd, txhua tus neeg yuav tsum tau xyuam xim tshwj xeeb rau peb lub ntsiab lus saum toj no thaum xaiv lub taub hau nqus
Yog tias cov lus qhia tsis zoo raug muab tso rau hauv kab nrog qhov pom tseeb, nws yuav ua rau muaj qhov sib txawv!
