Nws yog ib qho nyuaj rau ntseeg tias cov lus qhia yooj yim yas molded pov tseg yog kev ua neej nyob hauv lub ntiaj teb ntawm molecular biology, chemistry thiab tshuaj. Yog lawm, peb tab tom tham txog cov lus qhia pipette. Cov lus qhia no tsim kom muaj kev txhim khu kev qha thiab raug kaw. Pipette cov lus qhia tau muab faib ua peb yam sib txawv, suav nrog cov lus qhia tsis muaj menyuam, cov lus qhia ua ntej kom tsis muaj menyuam, thiab cov lus qhia lim.
Feem ntau siv pipette tip hom yog cov lus qhia tsis muaj menyuam. Lawv feem ntau yog siv rau hauv cov ntawv thov kev sim uas tsis muaj menyuam tsis muaj qhov tseem ceeb rau kev sim lossis kev sim ua. Ntawm qhov tod tes, cov lus qhia ua ntej sterilized pipette yog tsim los tiv thaiv kev sib kis. Lawv tau lees paub tsis pub muaj DNA, RNase, ATP thiab pyrogens. Vim tias cov lus qhia pipette no tau lees paub tsis pub dawb ntawm DNA, RNase, ATP thiab pyrogens, lawv yog qhov zoo tagnrho rau cov ntawv thov uas xav kom tsis muaj menyuam, xws li kab lis kev cai ntawm tes.
Lim cov lus qhia
Cov tswv yim lim yog tsim los tiv thaiv kev tsim aerosol. Aerosols yog cov pa me me ua kua lossis cov khoom siv. Cov khoom no tuaj yeem nyob hauv huab cua ntev ntev thiab tuaj yeem nqus tau. Ua kom qhov teeb meem loj dua, 65 feem pua ntawm cov kab mob hauv chav kuaj mob yog tshwm sim los ntawm aerosols, feem ntau yog los ntawm kev nqus pa. Cov lus qhia lim pipette pab txo qhov kev pheej hmoo ntawm kev tsim aerosol hauv chav kuaj. Lawv kuj tiv thaiv pipette stems los ntawm kev sib kis thiab txo qhov kev pheej hmoo ntawm kev sib kis. Cov lus qhia pipette no feem ntau siv rau hauv kev sib kis-sensitive daim ntaub ntawv xws li forensics thiab soj ntsuam kuaj.
Vim tias muaj peev xwm kis tau tus kab mob aerosol, peb tsis tuaj yeem ntxhov siab txaus qhov tseem ceeb ntawm kev tswj hwm kev ua haujlwm nyab xeeb hauv chav kuaj. Qhov no suav nrog kev ua kom tsis muaj menyuam ntawm cov pipettes thiab tuav cov lus qhia pipette tom qab siv.
