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, semuenzaniso, ine musanganiswa wezvinovaka muviri, zvinosanganisira makabhohaidhiretsi, mapuroteni, uye zvimwe zvakakosha zvinodiwa pakukura kwehutachiona.Masayendisiti anoshandisa petri ndiro kune zvinangwa zvakasiyana, zvinosanganisira:Kurima tupukanana: Petri ndiro inobvumira masayendisiti kutsika uye kukura kwakasiyana. microorganisms, iyo inogona kuonekwa yega kana kudzidza pamwe chete.Isolating microorganisms: Nekukwevera sampuli pane petri dish, mapoka ega ega e microorganisms anogona kuparadzaniswa uye akadzidzwa zvakasiyana.Kuedza kushandiswa kwemishonga inorwisa mabhakitiriya: Nekushandiswa kwema antibiotic-impregnated discs, masayendisiti anogona kuona. kushanda kwemishonga inorwisa mabhakitiriya kubva kune chaiwo ma microorganisms kuburikidza nekucherechedza nzvimbo dzekuvharira dzakatenderedza discs.Environmental monitoring: Petri ndiro dzinogona kushandiswa kunhonga mhepo kana pamusoro sampuli kuona kuvapo kwetwupukanana mune imwe nzvimbo.Petri ndiro chinhu chakakosha pamicrobiology. labs, kubatsira mukutsvagisa, kuongororwa, uye kudzidza kwema microorganisms.
