Kwirinda gukoresha ibiryo bya Petri
Isuku ryibiryo bya Petri
1. Kunyunyuza: Shira ibirahuri 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.
2. Kwoza: shyira ibirahuri byometse mumazi yogeje hanyuma uhanagure inshuro nyinshi ukoresheje brush yoroshye.Ntugasige 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. Kwoza: Imiyoboro nyuma yo koza no gutoragura igomba kuba yuzuye amazi.Niba inzabya zogejwe nyuma yo gutoranya bigira ingaruka ku ntsinzi cyangwa gutsindwa kwumuco w'akagari.Kwoza intoki ibikoresho byashizwemo, buri cyombo kigomba kuzuzwa inshuro nyinshi "kuzuza amazi - gusiba" byibuze inshuro 15, hanyuma ukakaraba inshuro 2-3 n'amazi asukuye, yumye cyangwa yumishijwe, hanyuma ugapakira kugirango uhagarare.
5. Ibyokurya byumuco wa pulasitike birashobora gukoreshwa muri rusange ni imirasire ya sterisile cyangwa imiti iyo bavuye muruganda.
Gutondekanya ibyokurya bya Petri
2. Irashobora kugabanywamo amasahani ya petri ya plastike hamwe nibirahuri bya petri ukurikije ibikoresho bitandukanye byo gukora, ariko ibyokurya bya petri bitumizwa hanze hamwe nibiryo bya petri bikoreshwa ni ibikoresho bya plastiki.
3. Ukurikije ubunini butandukanye, birashobora kugabanywa muri 35mm, 60mm na 90mm z'umurambararo.150mm ibiryo bya Petri.
4. Ukurikije ibice bitandukanye, irashobora kugabanywamo ibiryo 2 bitandukanye bya Petri, ibyokurya 3 bitandukanye bya Petri, nibindi.
5. Ibikoresho byibyokurya byumuco bigabanijwemo ibyiciro bibiri, cyane cyane plastiki nikirahure.Ikirahure kirashobora gukoreshwa mubikoresho byibimera, umuco wa mikorobe n'umuco wubahiriza ingirabuzimafatizo.Ibikoresho bya plastiki birashobora kuba ibikoresho bya polyethylene, bishobora gukoreshwa rimwe cyangwa inshuro nyinshi.Birakwiriye gukorerwa laboratoire, kwandika, no gutandukanya bagiteri, kandi birashobora gukoreshwa muguhinga ibikoresho byibimera.
Kwirinda gukoresha ibiryo bya Petri
1. Ibyokurya byumuco bisukurwa kandi byanduzwa mbere yo kubikoresha.Byaba bifite isuku cyangwa bidafite ingaruka zikomeye kumurimo, bishobora kugira ingaruka kuri pH yumuco.Niba imiti imwe nimwe ibaho, izabuza gukura kwa bagiteri.
2. Ibyokurya byumuco bimaze kugurwa bigomba kubanza gukaraba namazi ashyushye, hanyuma bigashyirwa mumazi ya 1% cyangwa 2% ya hydrochloric acide mumasaha menshi kugirango ukureho alkaline yubusa, hanyuma ukarabe kabiri n'amazi yatoboye.
3. Guhinga bagiteri, koresha amavuta yumuvuduko mwinshi (muri rusange 6.8 * 10 Pa yumuvuduko ukabije wimbaraga za 5), uyihagarike 30min kuri 120 ℃, uyumisha mubushyuhe bwicyumba, cyangwa ukoreshe ubushyuhe bwumye kugirango uyihagarike, ni ukuvuga, shyira ibiryo byumuco mu ziko, ubigumane kuri 2h kuri 120 ℃, hanyuma wice amenyo ya bagiteri.
4. Ibyokurya byumuco byangiritse birashobora gukoreshwa mugutera no guhinga.
