Lub tswv yim, raws li consumables siv nrog pipettes, feem ntau yuav muab faib ua: ①. Cov lus qhia lim, ②. Cov lus qhia txheej txheem, ③. Tsawg adsorption tswv yim, ④. Tsis muaj cua sov, thiab lwm yam.
1. Lub taub lim dej yog cov khoom siv uas tsim los kom tsis txhob muaj kab mob sib kis. Nws yog feem ntau siv hauv kev sim xws li molecular biology, cytology, thiab virology.
2. Cov lus qhia txheem yog cov lus qhia siv dav tshaj plaws. Yuav luag txhua qhov kev ua haujlwm pipetting tuaj yeem siv cov lus qhia zoo tib yam, uas yog hom kev lag luam zoo tshaj plaws.
3. Rau kev sim nrog cov kev xav tau siab, lossis cov qauv zoo nkauj lossis cov tshuaj reagents uas yooj yim kom nyob twj ywm, koj tuaj yeem xaiv cov lus qhia qis-adsorption kom nce tus nqi rov qab. Qhov saum npoo ntawm cov ntsiab lus qis adsorption tau dhau los ua kev kho mob hydrophobic, uas tuaj yeem txo qis qhov nro ntawm cov kua ua kua tawm ntau qhov seem ntawm lub taub. (Daim duab tsis tiav thiab lub cim xeeb yog txwv)
PS: Lub qhov ncauj dav dav yog qhov zoo tagnrho rau nqus cov khoom ntim, genomic DNA, thiab cov kua dej ntawm tes;
Cov ntsuas kev ua tau zoo ntawm cov lus qhia: qis adsorption, lim caij, nruj, quab yuam ntawm kev thauj khoom thiab ejection, tsis muaj DNase thiab RNase, tsis muaj pyrogen;
Yuav ua li cas xaiv ib lub tswv yim zoo? "Raws li cov lus qhia uas tuaj yeem ntsia tau yog cov lus qhia uas tuaj yeem siv tau"
—— Qhov no yog qhov kev nkag siab dav dav ntawm yuav luag txhua tus neeg siv ntawm kev hloov pauv ntawm lub taub hau nqus. Cov lus no tuaj yeem hais tau qee qhov tseeb tab sis tsis muaj tseeb kiag li.
Cov lus qhia uas tuaj yeem ntsia tau rau ntawm lub raj xa dej tuaj yeem tsim lub raj xa dej 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 xav tau cov ntaub ntawv hais lus.
1. Koj tuaj yeem xav ua qhov kev xeem ua haujlwm tom qab sib piv cov pipette nrog lub hau. Tom qab yaug lub taub hau, ua ob peb qhov ua piv txwv rov ua haujlwm ntxiv, ntsuas tus lej ntxiv rau txhua zaus, thiab sau cov ntawv nyeem.
2. Muab xam qhov tseeb thiab qhov tseeb ntawm kev ua haujlwm pipetting tom qab hloov mus rau hauv ntim raws li qhov ceev ntawm cov kua ntsuas.
3. Qhov peb yuav tsum xaiv yog cov lus qhia nrog qhov tseeb zoo. Yog tias qhov tseeb ntawm lub pipette thiab lub taub hau tsis zoo, nws txhais tau hais tias qhov nruj ntawm lub hau thiab lub pipette tsis tuaj yeem lav tau, yog li cov txiaj ntsig ntawm txhua qhov kev ua haujlwm tsis tuaj yeem rov ua dua.
Yog li dab tsi yog qhov tsawg kawg nkaus cov ntsiab lus rau lub tswv yim zoo?
Lub tswv yim zoo nyob ntawm qhov sib npaug, taper, thiab qhov tseem ceeb tshaj plaws yog adsorption;
1. Cia peb tham txog lub taper ua ntej: yog tias nws zoo dua, qhov kev sib tw nrog rab phom yuav zoo heev, thiab cov kua dej nqus tau zoo dua;
2. Concentricity: Lub concentricity yog seb lub voj voog ntawm lub taub hau thiab qhov txuas ntawm lub taub thiab lub pipette yog tib qhov chaw. 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 adsorptivity: lub adsorptivity yog cuam tshuam nrog cov khoom ntawm lub hau. Yog hais tias cov khoom ntawm lub taub hau tsis zoo, nws yuav cuam tshuam rau qhov tseeb ntawm qhov pipetting, uas ua rau muaj ntau cov kua tuav los yog cov ntawv luv rau dai rau ntawm phab ntsa, ua rau muaj kev ua yuam kev hauv pipetting;
Yog li txhua tus neeg yuav tsum tau ua tib zoo saib xyuas peb lub ntsiab lus saum toj no thaum xaiv lub taub hau nqus
