Chidiro chepetri chigadziko chisina kudzika, chine cylindrical, chakajeka, uye chinowanzoshandiswa mumarabhoritari kurima tupukanana, senge mabhakitiriya, fungi, kana zvimwe zvipenyu zvidiki. Yakatumidzwa zita remugadziri wayo, Julius Richard Petri. A petri dish inowanzogadzirwa negirazi kana purasitiki yakajeka, uye chivharo chayo chakakura muhupamhi uye zvishoma convex, zvichiita kuti nyore kurongedza ndiro dzakawanda. Iyo chivharo inodzivirira kusvibiswa ichiri kubvumira mhepo yakakwana.Petri ndiro dzakazadzwa nehutu hwekudya, hwakadai seagar, iyo inopa nzvimbo inotsigira yekukura kwe microorganisms. Nutrient agar, somuenzaniso, ine musanganiswa wezvokudya, kusanganisira makabhohaidhiretsi, mapuroteni, uye zvimwe zvinhu zvinokosha zvinodiwa kuti microbial kukura.Masayendisiti anoshandisa petri ndiro nokuda kwezvinangwa zvakasiyana-siyana, zvinosanganisira:Kurima microorganisms: Petri ndiro inobvumira masayendisiti kutsika uye kukura hutachiona hwakasiyana-siyana, hunogona kucherechedzwa mumwe nomumwe kana kudzidza kuburikidza nekuenzanisa microorganisms a isolating . dish, makoroni ega ega ehutachiona anogona kuparadzaniswa uye akadzidzwa zvakasiyana.Kuedza kushandiswa kwemishonga inorwisa mabhakitiriya: Nekushandiswa kwemishonga inorwisa mabhakitiriya-impregnated discs, masayendisiti anogona kuona kushanda kwemishonga inorwisa mabhakitiriya kune mamwe ma microorganisms kuburikidza nekucherechedza nzvimbo dzekudzivirira dzakapoteredza discs. madhishi chinhu chakakosha muMicrobiology labs, kubatsira mukutsvagisa, kuongororwa, uye kudzidza kwehutachiona.
