A petri dish ndiro yakajairika murabhoritari mudziyo, zvinosanganisira flat disc-shaped pasi uye chivharo, kunyanya kugadzirwa epurasitiki uye girazi, uye girazi rinogona kushandiswa chirimwa zvinhu, microbial tsika uye mhuka sero adherent tsika.Mazhinji epurasitiki anoraswa, akakodzera murabhoritari inoculation, streaking, uye kuparadzaniswa kwemabhakitiriya ekurima kwezvirimwa.
Nzira/nhanho:
1
Petri madhishi anowanzo gadzirwa neyakaomesesa svikiro yetsika tsika (ndiko kwakabva zita rendiro ndiro).Kugadzirwa kweplate medium ndeyekunyungudutsa yakaiswa sterilized agar medium nemvura inodziya (sterile), bvisa test tube donje plug, Pfuura muromo wechubhu pamusoro pemurazvo werambi redoro, wozovhura zvishoma chivharo cheiyo sterilized. culture dish, kuitira kuti muromo we test tube inogona kupinda mukati.Iyo yakagoverwa zvakaenzana pasi pendiro uye yakanyungudutswa kuti iwane ndiro tsika yepakati.

Nekuti kuberekana, kukura uye kukura kwebhakitiriya kune hukama hwakananga neiyo inopihwa svikiro (kudya kunovaka muviri), kunyanya kuongororwa kwehuwandu uye kuongororwa, ine kukosha kwakasimba kwehuwandu hwekudya kunopihwa.

Huwandu hwekudya kunopihwa panguva yebhakitiriya tsika, ingave yunifomu, uye kana pasi pe petri dish iri flat zvakakosha zvakanyanya.Kana pasi pe petri dish isina kuenzana, kugoverwa kweagar medium kuchasiyana zvichienderana nokuti pasi pe petri dish yakadzikama kana kwete.Iyo yekugovera haina kukwana, iyo yakanyatsoenderana nehuwandu hwekuongorora, saka pasi pehuwandu petri dish inodiwa kuti ive yakanyanya kupfava nekuda kwechikonzero.Nekudaro, kune zvakajairwa hunhu (kuongororwa kwebhakitiriya, kukura kwekoloni, kubereka, nezvimwewo), zvakajairika petri ndiro dzinogona kushandiswa.
Zvekungwaririra
Mushure mekuchenesa uye kuuraya hutachiona kusati kwashandiswa, ingave iyo petri dish yakachena kana kwete ine simba guru pabasa, izvo zvinogona kukanganisa pH yepakati.Kana pane mamwe makemikari, anodzivisa kukura kwebhakitiriya.
