1. Malangizo ntchito mbale chikhalidwe cell
Zakudya za Petri nthawi zambiri zimapangidwa ndi magalasi kapena pulasitiki, ndipo zimagwiritsidwa ntchito ngati zoyesera zopangira tizilombo toyambitsa matenda kapena zikhalidwe zama cell.Nthawi zambiri, mbale zamagalasi zitha kugwiritsidwa ntchito pazomera, zikhalidwe zazing'ono, komanso zikhalidwe zama cell anyama.Zinthu zapulasitiki zitha kukhala za polyethylene, zomwe ndi zoyenera kuyika ma labotale inoculation, scribing, ndi ntchito zolekanitsa mabakiteriya, ndipo zitha kugwiritsidwa ntchito kulima zinthu zobzala.Zakudya za Petri ndizosalimba, choncho ziyenera kusamaliridwa mosamala poyeretsa ndikugwiritsa ntchito.Akagwiritsidwa ntchito, ayenera kutsukidwa munthawi yake ndikusungidwa pamalo otetezeka komanso okhazikika.
2. Kuyeretsa mbale za Petri
1.） Zilowerereni: zilowerereni magalasi atsopano kapena ogwiritsidwa ntchito ndi madzi oyera kuti mufewetse ndikusungunula chomangiracho.Musanagwiritse ntchito magalasi atsopano, ingotsukani ndi madzi apampopi, ndiyeno zilowerereni mu 5% hydrochloric acid usiku wonse;Magalasi omwe amagwiritsidwa ntchito nthawi zambiri amakhala ndi mapuloteni ambiri ndi mafuta, omwe si ophweka kupukuta pambuyo poyanika, choncho ayenera kumizidwa m'madzi oyera mwamsanga mukangogwiritsa ntchito potsuka.
2.） Kutsuka: ikani magalasi oviikidwa m'madzi otsukira, ndikutsuka mobwerezabwereza ndi burashi yofewa.Osasiya ngodya zakufa ndikuletsa kuwonongeka kwa kumapeto kwa zotengera.Sambani ndi kuyanika kutsukidwa glassware kwa pickling.
3.） Pickling: Pickling ndi kuviika ziwiya zomwe zili pamwambazi mu njira yoyeretsera, yomwe imadziwikanso kuti acid solution, kuchotsa zotsalira zomwe zingatheke pamwamba pa zotengera pogwiritsa ntchito okosijeni wamphamvu wa asidi.Kukolola sikuyenera kuchepera maola asanu ndi limodzi, nthawi zambiri usiku kapena kupitilira apo.Samalani poyika ndi kutenga ziwiya.
4.） Kutsuka: Zotengerazo zikatha kutsukidwa ndi pickling ziyenera kutsukidwa ndi madzi.Kaya ziwiya osambitsidwa oyera pambuyo pickling mwachindunji zimakhudza bwino selo chikhalidwe.Pakutsuka pamanja kwa ziwiya zoziziritsa kukhosi, chotengera chilichonse chimayenera kudzazidwa mobwerezabwereza "madzi - kukhuthulidwa" kwa nthawi zosachepera 15, ndipo pamapeto pake amizidwa ndi madzi osungunuka kwa nthawi 2-3, zouma kapena zouma, ndikulongedza kuti asayime.
