Txhua Yam Koj Xav Paub Txog Pipette Lub Tswv Yim Thiab Ntau Ntxiv

Nws yog ib qho nyuaj rau ntseeg hais tias yooj yim, yas molded pov tseg cov lus qhia yog lub khob cij thiab butter ntawm molecular biology, chemistry thiab lub ntiaj teb ntawm cov tshuaj. Yog lawm, peb tab tom tham txog cov lus qhia pipette. Cov lus qhia no tsim kom muaj kev vam khom thiab muaj tseeb pipeting system. Cov lus qhia Pipette tuaj nyob rau hauv peb hom sib txawv xws li cov lus qhia tsis yog - tsis muaj menyuam, ua ntej - tsis muaj menyuam thiab lim cov lus qhia.

Feem ntau siv hom pipette taub yog non-sterile tswv yim. Lawv feem ntau siv rau hauv cov ntawv thov kev sim uas tsis muaj menyuam tsis 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 muaj 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.

Cov lus qhia lim pipette yog tsim los tiv thaiv aerosols los ntawm kev sib sau. Aerosols yog cov kua me me los yog cov khoom uas muaj cua. Cov khoom no tuaj yeem nyob hauv huab cua ntev ntev thiab tuaj yeem nqus tau. Txawm li cas los xij, 65% ntawm tag nrho cov kab mob hauv chaw kuaj mob yog tshwm sim los ntawm aerosols, feem ntau yog nqus tau lawv. Cov lus qhia lim pipette pab txo qhov kev pheej hmoo ntawm aerosols tsim hauv chav kuaj. Lawv kuj tiv thaiv cov pipette shafts los ntawm kev sib kis thiab txo qhov kev pheej hmoo ntawm kev sib kis kab mob. Cov lus qhia pipette no feem ntau yog siv rau hauv kev sib kis rhiab daim ntaub ntawv xws li forensics thiab kev kuaj mob.

Nrog rau qhov muaj peev xwm kis tau los ntawm aerosols, peb tsis tuaj yeem hais meej txaus tias nws tseem ceeb npaum li cas los tswj kev ua haujlwm nyab xeeb hauv chav kuaj. Qhov no suav nrog kev tua kab mob kom zoo tom qab siv thiab pov tseg cov lus qhia pipette.
