1. Inhalation qhov tob yuam kev
Yog tias cov kua dej tob hauv 8-channel pipetting workstation yog lawm, qhov tseeb tuaj yeem txhim kho los ntawm 5%. Raws li qhov loj ntawm lub taub hau nqus, qhov nqus qhov tob ntawm lub micropipette workstation yuav tsum yog 1-2 hli, thiab qhov nqus qhov tob ntawm qhov loj-scale pipette workstation yuav tsum yog 3-6 hli. Yog tias lub taub hau nqus dej nkag mus rau hauv cov kua dej tob heev, cov cua siab hauv lub taub hau nqus yuav nce, ua rau cov kua nqus dej ntau dhau.
2. Lub kaum sab xis hloov pauv tsis raug
Lub kaum sab xis ntawm lub pipette nyob rau hauv cov qauv yuav tsum nyob ze li ntawm 9 0 degrees, thiab qhov sib txawv ntawm txoj kab ntsug yuav tsum tsis pub tshaj 20 degrees. Lub kaum sab xis ntau dhau tuaj yeem ua rau lub taub hau nqus nqus kom nqus tau cov kua ntau dhau, ua rau qhov nqus tsis raug. Piv txwv li, thaum lub kaum sab xis ntawm 30 degrees los ntawm txoj kab ntsug, mus txog 0.7% ntawm cov kua yuav nqus tau ntau dhau.
3. Kev sib cais ua kua tsis sib xws
Los ntawm kev ua kom tiav kev sib cais ntawm cov tee dej ntxiv es tsis ua raws li qhov kawg ntawm lub taub hau nqus, qhov tseeb ntawm cov khoom thiab kev rov ua dua ntawm cov qauv tuaj yeem ua tiav. Rau feem ntau daim ntawv thov, nws raug nquahu kom siv lub hauv ntej kawg ntawm lub taub hau suction kom cais cov kua raws lub thawv phab ntsa, vim qhov no tuaj yeem txo lossis tshem tawm cov nqi ntawm cov qauv seem hauv lub taub hau nqus. Cov cuab yeej no tuaj yeem ua kom qhov tseeb ntawm 1% lossis siab dua.
4. Wetting yuam kev
Thaum siv lub raj xa dej los cais cov kua dej, cov phab ntsa sab hauv ntawm lub khob nqus dej yuav tsum tau npog nrog ib txheej ntawm cov kua, ua rau cov kua dej tawm me ntsis qis dua li qhov xav tau. ntub lub taub hau nqus tsev tshiab nrog cov kua yuav tsum tau siv tsawg kawg yog ob zaug ua ntej thiab kho sab hauv ntawm lub taub hau nqus.
5. Kev tsis sib haum xeeb ntawm kev thauj mus los ua kua
Tag nrho cov qauv yuav tsum tswj kom muaj qhov sib npaug sib npaug. Tsis txhob ua haujlwm nrawm lossis nrawm, thiab ua kom zoo ntawm txhua kauj ruam hauv cov txheej txheem ua kua.
