01 Cov khoom siv ntawm lub taub hau nqus
Tam sim no, lub pipette nozzle nyob rau hauv kev ua lag luam yeej siv polypropylene yas, hu ua PP, uas yog ib hom tsis muaj xim pob tshab yas uas muaj tshuaj inertia siab thiab ntau yam kub.
Txawm li cas los xij, tib yam yog polypropylene, yuav muaj qhov sib txawv ntawm qhov zoo: qhov zoo tshaj plaws nozzle feem ntau yog ua los ntawm ntuj polypropylene, thiab tus nqi qis nozzle zoo li yuav rov siv dua polypropylene yas, tseem hu ua PP rov ua dua, qhov no, peb tuaj yeem ua. tsuas yog hais tias nws cov khoom tseem ceeb yog polypropylene.
02 Lub ntim ntawm lub taub hau nqus
Lub pipette nozzle feem ntau yog ntim rau hauv hnab thiab thawv. Hauv kev lag luam uas paub tab, cov thawv ntim khoom muaj yeej; Thiab nyob rau hauv peb lub khw, lub hnab yog qhov tseem ceeb ntawm lub sijhawm tam sim no - feem ntau vim tias lawv pheej yig.
Qhov hu ua bagging, yog muab lub taub hau nqus rau hauv cov hnab yas, txhua lub hnab ntawm 500 lossis 1000 (tus naj npawb ntawm cov nplai loj nqus taub hau ib lub hnab yuav tsawg dua). Cov neeg siv khoom feem ntau yuav yuav lub hnab tom qab lub taub hau nqus, thiab tom qab ntawd muab lub taub hau nqus rau hauv lub thawv nqus, thiab tom qab ntawd siv lub tshuab nqus tsev siab kom tsis muaj menyuam.
Tsis tas li ntawd, nyob rau hauv xyoo tas los no, muaj ib hom tshiab ntawm lub taub hau ntim (8 los yog 10 phaj taub hau stacked rau hauv ib tug pej thuam, tuaj yeem muab tso rau hauv lub taub hau sai sai yam tsis tau kov lub taub hau). Lub tshuab nqus tsev yuav tsum muaj qhov chaw cia tsawg dua thiab txo qis kev siv cov yas, uas yog ib puag ncig zoo.
03 Tus nqi ntawm lub taub hau nqus
Cia peb pib nrog cov lus qhia ib txwm ntim (1000 ib lub hnab hauv 10μL, 200μL thiab 1000μL qhov ntau thiab tsawg). Bagged tswv yim muab faib ua peb qib:
① Ntshuam taub hau: kim tshaj plaws yog Eppendorf, ib lub hnab rau 400 ~ 500 yuan;
(2) Cov khoom lag luam txawv teb chaws, kev tsim khoom hauv tsev: tus neeg sawv cev ntawm qib no yog Axygen, nws tus nqi feem ntau yog 60 ~ 80 yuan, Axygen nozzle hauv kev lag luam feem ntau yog siab heev;
(3) Lub taub hau nqus tsev: xws li jiete suction taub hau, tus nqi ntau yog 130-220 yuan; Tus nqi ntau ntawm nesi suction taub hau feem ntau yog 50 ~ 230 yuan; Beekman biological suction taub hau, tus nqi ntau yog feem ntau 30-50 yuan. Feem ntau, tus nqi ntawm cov lus qhia hauv lub thawv yog 2-3 npaug ntawm cov lus qhia ntim, thaum cov lus qhia stacked yog 10-20% pheej yig dua li cov lus qhia.
04 Qhov haum ntawm lub taub hau nqus
Qhov tsim nyog ntawm cov lus qhia pipette yog lub ntsiab lus uas cov neeg siv tau them nyiaj ntau dua rau tam sim no. Vim li cas? Vim tias tsis yog txhua lub nozzles tuaj yeem siv rau hauv txhua hom pipette nrog cov khoom sib xws, yog li cov neeg siv khoom yuav tsum tau them sai sai rau qhov tsim nyog ntawm lub nozzle thaum yuav lub nozzle.
Peb tuaj yeem nkag siab qhov kev hloov pauv ntawm lub taub hau suction los ntawm cov hauv qab no:
(1) Qhov tshwj xeeb ntawm lub taub hau suction: qee lub npe ntawm qee lub raj xa dej tuaj yeem siv nws tus kheej lub taub hau nqus, lwm lub taub hau nqus tsis tuaj yeem siv. Rainin's multichannel pipette, piv txwv li, yuav tsum siv nws tus kheej LTS nozzles;
(2) Lub degree ntawm pipette adaptation: qhov teeb meem feem ntau yog tias lub pipette siv tau ntau yam pipettes, tab sis cov nyhuv ntawm pipette tom qab txhim kho cov pipettes sib txawv tsis zoo li qub. Feem ntau, cov qauv nozzles ua haujlwm zoo tshaj plaws, tab sis qee lub npe tseem zoo
(3) Pipette thiab pipette ntau yam kom phim: nyob rau hauv ib txwm muaj xwm txheej, qhov ntim ntawm cov pipette yuav tsum ntau dua los yog sib npaug rau qhov siab tshaj plaws pipette ntau yam, xws li 200μL pipette tuaj yeem siv rau qhov siab tshaj plaws pipette ntau ntawm 20μL, 100μL thiab 200μL;
Tshwj xeeb tuaj yeem sab laj peb cov neeg ua haujlwm muag khoom, kom ntseeg tau tias cov neeg siv khoom tuaj yeem yuav lub nozzle tsim nyog ~
05 Suction taub hau nrog cov khoom lim
Lub taub hau suction nrog cov khoom lim yog lub lim dej nyob rau sab sauv kawg ntawm lub taub hau nqus, feem ntau yog dawb. Cov khoom lim feem ntau yog ua los ntawm polypropylene, zoo ib yam li cov qauv ntawm lub tshuab lim luam yeeb.
Vim lub xub ntiag ntawm lub lim dej, cov qauv tshem tawm tsis tuaj yeem nkag mus rau hauv pipette sab hauv, yog li tiv thaiv cov pipette Cheebtsam los ntawm kev sib kis thiab corrosion, thiab tseem ceeb tshaj, kom ntseeg tau tias tsis muaj kev sib kis ntawm cov qauv. Yog li ntawd, lub taub hau nqus nrog cov khoom lim kuj yog ib qho tseem ceeb rau kev tshem tawm cov qauv tsis zoo thiab corrosive.
