Qhov tseem ceeb ntawm Pipette Cov Lus Qhia hauv Kev Tiv Thaiv Kab Mob Sib Kis

Pipette tswv yimyog cov cuab yeej tseem ceeb hauv cov chaw kuaj xyuas kom meej ntsuas thiab hloov cov kua dej. Txawm li cas los xij, lawv kuj ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev sib kis ntawm cov qauv. Lub cev thaiv lub cev tsim los ntawm cov khoom lim hauv lub pipette tip suppresses thiab blocks aerosols, zoo tiv thaiv tej yam muaj peev xwm. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog thaum ua haujlwm nrog cov qauv rhiab xws li nucleic acids, vim tias txawm tias qhov sib kis me me tuaj yeem ua rau cov txiaj ntsig tsis raug.

Cov ntsiab lus lim hauv lub taub hau pipette ua raws li kev thaiv, tiv thaiv aerosols los ntawm kev nkag mus rau hauv pipette thiab tuaj rau hauv kev sib cuag nrog cov qauv raug xa mus. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog thaum ua haujlwm nrog cov qauv uas muaj cov nucleic acids, vim tias cov molecules no tsis tshua muaj siab rau kev sib kis. Txawm tias muaj pes tsawg tus neeg txawv teb chaws DNA lossis RNA tuaj yeem ua rau cov txiaj ntsig tsis raug, yog li qhov tseeb ntawm pipette yog qhov tseem ceeb hauv molecular biology thiab kev tshawb nrhiav caj ces.

Ntxiv nrog rau kev tiv thaiv kom tsis txhob muaj kab mob nkag mus rau hauv pipette, lim cov ntsiab lus tseem tiv thaiv cov qauv raug xa mus. Los ntawm kev thaiv cov aerosols thiab lwm yam kab mob, cov khoom lim kom paub meej tias cov qauv kev ncaj ncees raug tswj xyuas thoob plaws hauv cov txheej txheem pipetting. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog thaum ua haujlwm nrog cov qauv tseem ceeb lossis tsawg, vim tias txhua qhov kev poob lossis kev sib kis tuaj yeem ua rau muaj qhov tshwm sim loj.

Tsis tas li ntawd, cov txheej txheem lim dej hauv cov lus qhia pipette tiv thaiv tsis tau tsuas yog muaj kab mob xwb tab sis kuj muaj cov kab mob nucleic acid. Qhov no yog lub luag haujlwm tseem ceeb thaum ua cov qauv DNA lossis RNA, vim tias kev tswj xyuas qhov huv ntawm cov khoom siv caj ces yog qhov tseem ceeb rau kev txheeb xyuas thiab kev tshawb fawb. Pipette cov lus qhia zoo thaiv thiab muaj cov aerosols thiab cov kab mob sib kis, ua kom muaj kev ntseeg siab thiab kev ncaj ncees ntawm cov qauv ua tiav.

Hauv cov chaw kuaj mob, qhov twg ntau cov qauv feem ntau ua tiav ib txhij, qhov kev pheej hmoo ntawm kev sib kis kab mob yog qhov teeb meem tsis tu ncua. Pipette cov lus qhia nrog cov ntsiab lus lim muab cov kev daws teeb meem txhim khu kev qha rau qhov teeb meem no, muab lub cev muaj zog uas tiv thaiv kev hloov pauv ntawm cov kab mob sib kis ntawm cov qauv. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov teb xws li microbiology, qhov uas muaj kev pheej hmoo ntawm kev sib kis kab mob tuaj yeem cuam tshuam qhov kev siv tau ntawm kev sim cov txiaj ntsig.

Hauv cov ntsiab lus,cov lus qhia pipettenrog cov ntsiab lus lim ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev sib kis ntawm cov qauv kuaj. Lub cev thaiv lub cev tsim los ntawm cov khoom lim inhibits thiab thaiv cov aerosols, tiv thaiv kom tsis txhob kis kab mob thiab tswj kev ncaj ncees ntawm cov qauv rhiab xws li nucleic acids. Los ntawm kev xaiv cov lus qhia zoo pipette nrog cov ntsiab lus lim, cov kws tshawb fawb tuaj yeem ua kom qhov tseeb thiab kev ntseeg siab ntawm cov txiaj ntsig kev sim, thaum kawg pab txhawb kev nce qib ntawm kev paub txog kev tshawb fawb thiab kev tshawb pom.
