Cov ntaub ntawv thiab kev nyab xeeb: Feem ntau yog cov yas pov tseg, uas yuav tsum tsis yog - tshuaj lom thiab muaj biocompatibility zoo los tiv thaiv cov qauv paug. Piv txwv li, polyethylene yog pob tshab thiab hloov tau, ua rau nws tsim nyog rau kev siv niaj hnub; Txawm li cas los xij, rau cov txheej txheem uas yuav tsum muaj qhov kub thiab txias los yog tshuaj lom neeg, cov khoom siv polypropylene lossis iav yuav tsum raug txiav txim siab.
Kawm tiav thiab Precision: Ntshiab, abrasion -cov cim kawm tiav yog qhov tseem ceeb; kev faib ua haujlwm zoo-xws li 0.1 mL increments- ua kom yooj yim rau kev khiav hauj lwm, xws li piv txwv ntxiv lossis dilution. High-cov khoom lag luam raug ntsuas feem ntau yog ntsuas thiab ua kom muaj qhov ua siab ntev (piv txwv li, ± 0.05 mL).
Sterilization thiab Ntim: Ntau daim ntawv thov xav tau ib puag ncig tsis muaj menyuam; yog li ntawd, cov khoom yuav raug sterilized los ntawm gamma irradiation los yog ethylene oxide kev kho mob thiab feem ntau muab nyob rau hauv ib tug neeg ntim khoom (xws li, ntawv- hnab yas) los tiv thaiv kev kis kab mob. Tsis yog- cov qauv tsis muaj menyuam yog tsim nyog rau kev sim dav dav.
Daim Ntawv Thov: Cov pipettes no tau siv dav hauv thaj chaw xws li molecular biology, kab lis kev cai ntawm tes, kev kuaj mob, thiab chaw kuaj mob. Hauv cov txheej txheem ntawm tes, yuav tsum tau saib xyuas kom tsis txhob khawb kab lis kev cai tais diav; conversely, nyob rau hauv tshuaj thwmsim, cov pipettes yuav tsum muaj corrosion kuj.
