Lub tswv yim, raws li consumables siv nrog pipettes, feem ntau yuav muab faib ua qauv qhia; lim tswv yim;conductive lim pipette tswv yim, lwm.
1. Cov lus qhia tus qauv yog siv dav dav. Yuav luag txhua txoj haujlwm pipetting tuaj yeem siv cov lus qhia zoo tib yam, uas yog cov lus qhia pheej yig tshaj plaws.
2. Cov ntsiab lus lim dej yog cov khoom siv uas tsim los kom tsis txhob muaj kab mob sib kis thiab feem ntau siv rau hauv kev sim xws li molecular biology, cytology, thiab virology.
3. 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.
PS: Lub qhov ncauj dav dav yog qhov zoo tagnrho rau nqus cov khoom khov, genomic DNA, thiab cov kua dej ntawm tes.
Yuav ua li cas xaiv ib tug zoo pipette taub hau?
Cov lus hais 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.
Cov yam ntxwv ntawm lub taub hau pipette
Yog li dab tsi yog qhov tsawg kawg nkaus cov ntsiab lus uas cov lus qhia zoo yuav tsum muaj?
Lub tswv yim zoo nyob ntawm qhov sib npaug, taper, thiab qhov tseem ceeb tshaj plaws yog adsorption;
1. Cia peb tham txog taper ua ntej: yog tias nws zoo dua, kev sib tw nrog lub pipette yog qhov zoo heev.
2. Concentricity: Concentricity yog seb lub voj voog nruab nrab 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 txoj kev nqus: absorptivity yog txuam nrog cov khoom ntawm lub taub. Yog hais tias cov khoom ntawm lub taub hau tsis zoo, nws yuav cuam tshuam rau qhov tseeb ntawm pipetting thiab ua rau cov kua dej ntau kom khaws cia los yog hu ua dai rau ntawm phab ntsa, ua rau muaj kev ua yuam kev hauv pipetting.
Yog li txhua tus neeg yuav tsum tau xyuam xim tshwj xeeb rau peb lub ntsiab lus saum toj no thaum xaiv lub taub hau pipette. Ib kab ntawm cov lus qhia phem tau meej meej sib txawv! Koj yuav pom pom kev tsis sib haum xeeb, tab sis qhov no yog ib kauj ruam tseem ceeb hauv kev xaiv cov lus qhia zoo. Tsis tas li ntawd, thov nco ntsoov lub installation ntawm cov lus qhia ntawm ib leeg-channel pipette thiab ntau-channel pipette txawv. Rau ib leeg-channel ib qho, ntxig lub hau vertically rau hauv lub taub hau pipette, nias maj mam, thiab tig nws me ntsis kom nruj nws. Rau ntau cov channel, ntau txoj hauv kev ntawm lub pipette yuav tsum tau ua raws li ntau lub tswv yim, muab tso rau ntawm lub kaum sab xis, thiab me ntsis co rov qab mus rau nruj; Tsis txhob rov ntaus lub pipette kom paub meej tias qhov airtightness ntawm lub ntsis.
Teb cov lus nug no xav tau cov ntaub ntawv hais lus
1. Sib phim lub pipette nrog lub ntsis rau kev ntsuas kev ua tau zoo.
2. xam 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 kom muaj lub tswv yim zoo. Yog hais tias lub pipette thiab lub taub hau tsis zoo sib xws, 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 rov tsim dua.
