Lub tais petri yog ib qho ntiav, cylindrical, pob tshab, thiab feem ntau tsis muaj cov thawv uas siv nyob rau hauv lub chaw soj nstuam rau culturing microorganisms, xws li cov kab mob, fungi, los yog lwm yam kab mob me.Nws yog lub npe hu ua tom qab nws inventor, Julius Richard Petri.Ib lub tais petri feem ntau yog ua los ntawm iav los yog yas ntshiab, thiab nws lub hau yog loj dua nyob rau hauv txoj kab uas hla thiab me ntsis convex, tso cai rau yooj yim stacking ntawm ntau yam tais diav.Lub hau tiv thaiv kev kis kab mob thaum tseem tso cai rau kom muaj cua txaus txaus.Petri tais diav ntim nrog cov khoom noj nruab nrab, xws li agar, uas muab kev txhawb nqa rau kev loj hlob ntawm cov kab mob.Nutrient agar, piv txwv li, muaj cov khoom noj sib xyaw, suav nrog cov carbohydrates, cov protein, thiab lwm yam tseem ceeb uas yuav tsum tau muaj rau kev loj hlob ntawm cov kab mob microbial.Cov kws tshawb fawb siv cov tais diav petri rau ntau lub hom phiaj, xws li: Kev coj noj coj ua ntawm cov kab mob: Petri tais diav pub rau cov kws tshawb fawb txog kab lis kev cai thiab loj hlob ntau yam. Cov kab mob, uas tuaj yeem pom ib tus zuj zus los yog kawm ua ke.Kev cais cov kab mob: Los ntawm streaking tus qauv mus rau ib lub tais petri, ib tus neeg cov kab mob tuaj yeem raug cais thiab kawm cais.Testing antibiotic susceptibility: Nrog kev siv cov tshuaj tua kab mob-impregnated discs, cov kws tshawb fawb tuaj yeem txiav txim siab. Kev ua tau zoo ntawm cov tshuaj tua kab mob tiv thaiv cov kab mob tshwj xeeb los ntawm kev soj ntsuam cov cheeb tsam ntawm inhibition nyob ib puag ncig cov discs.Kev saib xyuas ib puag ncig: Petri cov tais diav tuaj yeem siv los sau cov huab cua lossis cov qauv saum npoo los txiav txim seb muaj cov kab mob nyob hauv ib puag ncig.Petri cov tais diav yog cov cuab yeej tseem ceeb hauv microbiology. labs, pab kev tshawb fawb, kuaj mob, thiab kev tshawb fawb ntawm cov kab mob.
