Micro-Operating Dish
Ibisobanuro bigufi:
Ikoreshwa mukureba imiterere ya oocytes, selile cumulus munsi ya microscope, gutunganya oocytes peripheral granular selile, gutera intanga muri ovum.
Ibyokurya bya Petri ni ibihe?
Ibyokurya bya Petri ni silindrike idakabije, ikirahuri kizengurutse gikoreshwa muri laboratoire mu muco mikorobe zitandukanye na selile.Kwiga mikorobe nka bagiteri & virusi ukurikiranwa cyane, ni ngombwa kubitandukanya nandi moko cyangwa ibintu.Muyandi magambo, ibiryo bya Petri bikoreshwa mugushigikira imikurire ya mikorobe.Bumwe mu buryo bwiza bwo gukora ibi nubufasha bwumuco uciriritse mubikoresho bikwiye.Ibyokurya bya Petri nibyo byiza guhitamo umuco wo hagati.
Isahani yahimbwe n’umudage w’umudage witwa Julius Richard Petri.Ibyokurya bya Petri ntabwo bitangaje, bamwitiriwe.Kuva yatangira, ibiryo bya Petri byabaye kimwe mubikoresho bya laboratoire.Muri iyi ngingo ya Siyanse Yubumenyi, tuzasangamo muburyo burambuye uburyo bwo gukoresha ibiryo bya Petri muri laboratoire yubumenyi bwa siyanse & intego zayo zitandukanye.
Kuki Gukoresha ibiryo bya Petri muri laboratoire?
Ibiryo bya Petri bikoreshwa cyane nkibikoresho bya laboratoire mubijyanye na biologiya na chimie.Ibyokurya bikoreshwa mumikorere ya selile itanga umwanya wo kubikamo no kubarinda kwanduza.Kubera ko isahani ibonerana, biroroshye kureba neza imikurire ya mikorobe.Ingano yibiryo bya Petri ituma ishobora kubikwa munsi ya microscope kugirango irebe neza bitabaye ngombwa ko iyimurira kuri plaque microscopique.Kurwego rwibanze, ibiryo bya Petri bikoreshwa mumashuri makuru na kaminuza mubikorwa nko kwitegereza imbuto.
Nigute wakoresha ibiryo bya Petri neza muri laboratoire
Mbere yo gukoresha ibiryo bya petri ni ngombwa kumenya neza ko bifite isuku rwose kandi bitarimo microparticles zose zishobora kugira ingaruka kubushakashatsi.Urashobora kubyemeza uvura ibiryo byose byakoreshejwe hamwe na blach hanyuma ukabikoresha kugirango ukoreshwe.Menya neza ko uhindura ibiryo bya Petri mbere yo kubikoresha.
Kugira ngo witegereze imikurire ya bagiteri, tangira wuzuza isahani hamwe na agar (yateguwe hifashishijwe algae itukura).Agar medium irimo intungamubiri, amaraso, umunyu, ibipimo, antibiotike, nibindi bifasha mukura mikorobe.Komeza ubike amasahani ya Petri muri firigo mumwanya wo hejuru.Mugihe ukeneye ibyapa byumuco, ubikure muri firigo hanyuma ubikoreshe nibisubira mubushyuhe bwicyumba.
Kujya imbere, fata urugero rwa bagiteri cyangwa izindi mikorobe iyo ari yo yose hanyuma uyisukeho buhoro buhoro umuco cyangwa ukoreshe ipamba kugirango uyishyire kumuco muburyo bwa zigzag.Menya neza ko udashyizeho ingufu nyinshi kuko ibi bishobora gusenya umuco.
Ibi nibimara gukorwa, funga isahani ya Petri umupfundikizo hanyuma uyipfundike neza.Bika munsi ya 37ºC muminsi mike hanyuma wemere gukura.Nyuma yiminsi mike, sample yawe izaba yiteguye gukora ubundi bushakashatsi.
