I-petri dish iyisitsha esingashoni, esiyisilinda, esisobala, futhi esivamise ukuba yinyumba esetshenziswa ezindaweni zokucwaninga ukuze kukhuliswe amagciwane, afana namagciwane, isikhunta, noma ezinye izinto ezincane. Siqanjwe ngomsunguli waso, uJulius Richard Petri.Isitsha se-petri ngokuvamile senziwe ngengilazi noma ngepulasitiki ecacile, futhi isivalo saso sikhulu ngobubanzi futhi sijike kancane, okuvumela ukupakishwa kalula kwezitsha eziningi. Isivalo sivimbela ukungcola ngenkathi sisavumela ukugeleza komoya okwanele.Izitsha zePetri zigcwaliswa ngendawo yezakhi, njenge-agar, ehlinzeka ngendawo esekelayo yokukhula kwama-microorganisms. I-nutrient agar, isibonelo, iqukethe ingxube yemisoco, okuhlanganisa ama-carbohydrate, amaprotheni, nezinye izakhi ezibalulekile ezidingekayo ekukhuleni kwe-microbial.Ososayensi basebenzisa izitsha ze-petri ngezinhloso ezihlukahlukene, okuhlanganisa:Ukuhlakulela ama-microorganisms: Izitsha ze-Petri zivumela ososayensi ukuba benze isiko futhi bakhulise ama-microorganisms ahlukahlukene, angabonwa ngawodwana noma afundwe ngesampula nge-microorganisms i-isolating ngokuhlanganyela. dish, amakholoni ngamanye ama-microorganisms angahlukaniswa futhi afundwe ngokwehlukana.Ukuhlola ukuthambekela kwe-antibiotic: Ngokusetshenziswa kwama-antibiotic-impregnated discs, ososayensi bangakwazi ukucacisa ukusebenza kahle kwama-antibiotic ngokumelene nama-microorganisms athile ngokubheka izindawo zokuvimbela ezizungezile ama-disc.Ukuqapha kwemvelo: Izitsha ze-Petri zingase zisetshenziselwe ukuqoqa isampula ye-microperganism ethile ukuze kuqoqwe indawo yomoya. izitsha ziyithuluzi eliyisisekelo kumalebhu e-microbiology, elisiza ocwaningweni, ekuxilongeni nasekuhloleni amagciwane.
