1. Amabwiriza yo gukoresha ibiryo byumuco
Ibyokurya bya Petri mubusanzwe bikozwe mubirahuri cyangwa plastike, kandi mubisanzwe bikoreshwa nkibigeragezo byo guhinga mikorobe cyangwa imico ya selile.Mubisanzwe, ibirahuri birashobora gukoreshwa mubikoresho byibimera, imico ya mikorobe, hamwe n’umuco wubahiriza ingirabuzimafatizo.Ibikoresho bya pulasitike birashobora kuba ibikoresho bya polyethylene, bikwiranye no gutera laboratoire, kwandika, hamwe na bagiteri yo gutandukanya bagiteri, kandi birashobora gukoreshwa muguhinga ibikoresho byibimera.Ibyokurya bya petri biroroshye, bigomba rero kwitabwaho mugihe cyo gukora isuku no kubikoresha.Nyuma yo kuyikoresha, igomba gusukurwa mugihe ikabikwa ahantu hizewe kandi hateganijwe.
2. Gusukura ibiryo bya Petri
1.） Wibike: Shira ibikoresho bishya cyangwa byakoreshejwe ibirahuri n'amazi meza kugirango woroshye kandi ushonga umugereka.Mbere yo gukoresha ibikoresho bishya by'ibirahure, kwoza gusa n'amazi ya robine, hanyuma ubishire muri acide hydrochloric 5% ijoro ryose;Ibikoresho bikoresha ibirahuri bikoreshwa akenshi birimo proteyine n'amavuta menshi, ntibyoroshye guhanagura nyuma yo gukama, bityo bigomba kwibizwa mumazi meza ako kanya nyuma yo gukoreshwa mu koza.
2Ntugasige inguni zapfuye kandi wirinde kwangirika kurangiza hejuru yabyo.Karaba kandi wumishe ibikoresho byibirahure bisukuye kugirango ushire.
3.） Gutoragura: Gutoragura ni ukunyunyuza imiyoboro yavuzwe haruguru mugisubizo cyogusukura, kizwi kandi nkumuti wa aside, kugirango ukureho ibisigisigi bishoboka hejuru yubwato binyuze muri okiside ikomeye yumuti wa aside.Gutoragura ntibishobora kuba munsi yamasaha atandatu, muri rusange ijoro cyangwa birenga.Witondere mugihe ushyira no gufata ibikoresho.
4. ins Gukaraba: Imiyoboro nyuma yo koza no gutoragura igomba kwozwa neza namazi.Niba inzabya zogejwe neza nyuma yo gutoranya bigira ingaruka kumico yumuco.Kwoza intoki inzabya zashizwemo, buri cyombo kigomba kuzuzwa inshuro nyinshi "kuzuza amazi - gusiba" byibuze inshuro 15, hanyuma ukarangiza amazi yatoboye inshuro 2-3, akuma cyangwa akuma, hanyuma agapakira kugirango ahagarare.
