1. Imiyalo yokusebenzisa izitsha ze-cell culture
Izitsha ze-Petri ngokuvamile zenziwe ngengilazi noma ngepulasitiki, futhi zivame ukusetshenziswa njengezinto ezisetshenziswayo zokuhlola ukutshala ama-microorganisms noma amasiko amaseli.Ngokuvamile, izitsha zengilazi zingasetshenziselwa izinto zezitshalo, amasiko e-microbial, kanye namasiko anamathelayo wamaseli ezilwane.Izinto zepulasitiki zingase zibe impahla ye-polyethylene, elungele ukujova elabhorethri, i-scribing, kanye nemisebenzi yokuhlukanisa amagciwane, futhi ingasetshenziselwa ukutshala izinto zezitshalo.Izitsha zePetri zintekenteke, ngakho-ke kufanele ziphathwe ngokucophelela ngesikhathi zihlanzwa futhi zisetshenziswa.Ngemuva kokusetshenziswa, kufanele zihlanzwe ngesikhathi futhi zigcinwe endaweni ephephile futhi engashintshi.
2. Ukuhlanzwa kwezitsha zePetri
1.） Gcoba: Cwilisa izitsha zengilazi ezintsha noma ezisetshenzisiwe ngamanzi ahlanzekile ukuze uthambise futhi uhlakaze okunamathiselwe.Ngaphambi kokusebenzisa i-glassware entsha, vele uyixube ngamanzi kampompi, bese uyicwilisa ku-5% we-hydrochloric acid ngobusuku bonke;I-glassware esetshenzisiwe ngokuvamile iqukethe amaprotheni amaningi namafutha, okungelula ukuxubha ngemva kokumisa, ngakho kufanele ifakwe emanzini ahlanzekile ngokushesha ngemva kokusetshenziswa ukuxubha.
2.） Ukuxubha: faka ingilazi ecwilisiwe emanzini okugeza, bese uxubha ngokuphindaphindiwe ngebhulashi elithambile.Ungawashiyi amakhona afile futhi uvimbele ukulimala endaweni engaphezulu kweziqukathi.Geza futhi usule i-glassware ehlanjululwe yokukhetha.
3.） Ukukha i-Pickling: I-Pickling iwukucwilisa izitsha ezingenhla kwisisombululo sokuhlanza, esaziwa nangokuthi isixazululo se-asidi, ukususa izinsalela ezingaba khona ebusweni bemikhumbi ngokusebenzisa i-oxidation eqinile yesisombululo se-asidi.Ukuvuthwa akumele kube ngaphansi kwamahora ayisithupha, ngokuvamile ebusuku noma ngaphezulu.Qaphela lapho ubeka futhi uthatha izitsha.
4.） Ukuhlanzwa: Izitsha ngemva kokuxubha nokucwiliswa kufanele zihashazwe ngokugcwele ngamanzi.Ukuthi izitsha zigezwa zihlanzeke ngemuva kokugcotshwa kuthinta ngqo impumelelo yesiko lamaseli.Ukugeza ngezandla izitsha ezifakwe emanzini anosawoti, isitsha ngasinye sizogcwaliswa ngokuphindaphindiwe "ngamanzi - sithululwe" okungenani izikhathi ezingu-15, futhi ekugcineni sicwiliswe ngamanzi a-distilled izikhathi ezingu-2-3, omisiwe noma omisiwe, futhi apakishwe ukuze abekwe eceleni.
