Kutsuka mbale za Petrindi njira yotopetsa, koma njirayi imatha kupanga zoyeserera kukhala zogwira mtima.Ngati mbale ya petri sinayeretsedwe, woyeserayo amayenera kuwononga nthawi yochulukirapo pokonza zoyeserera.Ndipo ngati mbale ya petri yatsukidwa bwino, woyesera akhoza kuyesa bwino kwambiri.
Kuyeretsa pamanja mbale za Petri:
Nthawi zambiri, imadutsa masitepe anayi a kuviika, kutsuka, pickling, ndi kuyeretsa.
1. Kuviika: Zida zamagalasi zatsopano kapena zogwiritsidwa ntchito ziyenera kuviikidwa m'madzi kaye kuti zifewetse ndi kusungunula zomata.Zagalasi zatsopano ziyenera kutsukidwa ndi madzi apampopi musanagwiritse ntchito, ndiyeno ziviikidwa usiku wonse mu 5% hydrochloric acid;magalasi ogwiritsidwa ntchito nthawi zambiri amakhala ndi mapuloteni ambiri ndi mafuta omwe amamangiriridwa, zomwe zimakhala zosavuta kutsuka mukatha kuyanika, choncho ziyenera kumizidwa m'madzi oyera mwamsanga mukangogwiritsa ntchito kuchapa.
2. Kukucha: Ikani zida zagalasi zoviikidwa m'madzi otsukira ndikutsuka mobwerezabwereza ndi burashi yofewa.Osasiya malo akufa ndi kupewa kuwonongeka pamwamba pa mapeto a ziwiya.Sambani ndi kupukuta zotsukidwa glassware kwa pickling.
3. Pickling: Pickling ndi kuviika ziwiya zomwe zatchulidwa pamwambapa muzitsulo zoyeretsera, zomwe zimadziwikanso kuti acid solution, kuchotsa zinthu zomwe zingathe kutsalira pamwamba pa ziwiya pogwiritsa ntchito okosijeni wamphamvu wa asidi.Kukolera sikuyenera kuchepera maola asanu ndi limodzi, nthawi zambiri usiku kapena kupitilira apo.Samalani ndi ziwiya.
4. Muzimutsuka: Ziwiya mukatsuka ndi kuzitola ziyenera kutsukidwa ndi madzi.Kaya ziwiya ndi kuchapidwa woyera pambuyo pickling mwachindunji zimakhudza bwino kapena kulephera kwa selo chikhalidwe.Sambani m'manja ziwiya pambuyo pickling, ndipo chiwiya aliyense ayenera mobwerezabwereza "kudzazidwa ndi madzi-chopanda kanthu" osachepera 15 nthawi, ndipo potsirizira pake ankawaviika pawiri osungunula madzi kwa nthawi 2-3, zouma kapena zouma, ndi kulongedza ntchito mtsogolo.

Njira yoyeretsera yogwiritsira ntchito XPZma laboratory glassware washerkuyeretsa mbale ya petri:
Kuchuluka koyeretsa: mbale 168 za petri zitha kutsukidwa mugulu limodzi
Nthawi yoyeretsa: Mphindi 40 kuti mumalize kuyeretsa
Njira yoyeretsera: 1. Ikani mbale ya petri kuti itsukidwe (yatsopanoyo ikhoza kuikidwa mwachindunji mu chochapira mabotolo, ndipo mbale ya petri yokhala ndi sing'anga ya chikhalidwe iyenera kutsanulira chidutswa chachikulu cha chikhalidwe cha chikhalidwe momwe mungathere) mudengu lofananira. wa wochapira mabotolo.Wosanjikiza umodzi amatha kuyeretsa mbale 56 za petri, ndipo nthawi imodzi amatha kuyeretsa mbale 168 zosanjikiza zitatu.
2. Tsekani chitseko cha makina ochapira botolo, sankhani pulogalamu yoyeretsa, ndipo makinawo amayamba kuyeretsa.Njira yoyeretsera imaphatikizapo kuyeretsa chisanadze - kutsuka kwakukulu kwa alkali - acid neutralization - kutsuka kwamadzi oyera.
3. Mukatsuka, chitseko cha makina ochapira mabotolo chimangotseguka, ndikutulutsa mbale yotsukidwa, ndikusunthira ku zida zotsekera.
Kuyeretsa mbale za petri m'ma laboratories achilengedwe ndi gawo lofunikira kwambiri pakuwongolera ma labotale.Kugwiritsa ntchito makina ochapira mabotolo odziwikiratu m'malo moyeretsa pamanja kungapewe kuipitsidwa ndi data yoyeserera, kuteteza thanzi la anthu oyesera, ndikuwongolera luso loyesera.
