Lub tais petri yog ib qho ntiav, cylindrical, pob tshab, thiab feem ntau tsis muaj cov thawv uas siv nyob rau hauv cov chaw soj nstuam rau kev cog qoob loo, xws li kab mob, kab mob, lossis lwm yam kab mob me. Nws muaj npe tom qab nws tus neeg tsim khoom, 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, uas tso cai rau kom 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, nrog rau 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, suav nrog: Kev coj noj coj ua ntawm cov kab mob: Petri tais tso cai rau cov kws tshawb fawb txog kab lis kev cai thiab loj hlob ntau yam kab mob, uas tuaj yeem soj ntsuam ib tus zuj zus los yog kawm ua ke.Isolating microorganisms ntawm ib tus neeg cov tais diav: Cov kab mob tuaj yeem raug cais thiab kawm cais.Testing antibiotic susceptibility: Nrog rau kev siv cov tshuaj tua kab mob-impregnated discs, cov kws tshawb fawb tuaj yeem txiav txim siab qhov ua tau zoo ntawm cov tshuaj tua kab mob tiv thaiv kab mob tshwj xeeb los ntawm kev soj ntsuam cov cheeb tsam ntawm inhibition nyob ib puag ncig discs.Environmental monitoring: Petri cov tais diav tuaj yeem siv los sau cov huab cua los yog cov qauv saum npoo los txiav txim seb qhov muaj pes tsawg leeg ntawm cov khoom siv microorganisms. labs, pab kev tshawb fawb, kuaj mob, thiab kev tshawb fawb ntawm cov kab mob.
