Kungani izitsha zikaPetri zingena lapho kufakwa ama-microorganisms?

1. Yehlisa ukuhwamuka: Ukubuyisa isidlo sesiko kunganciphisa ukuhwamuka kwamanzi aphakathi esitsheni sesiko;

2. Ukufinyelela okulula: Isembozo sesitsha se-petri sikhulu futhi phansi mncane. Uma kubekwe eqondile, kulula ukukhipha isembozo kuphela lapho uthatha khona, okuzobangela ukuvezwa kwesiko eliphakathi esitsheni se-petri, esingadala ukungcoliswa kwesiko eliphakathi noma lokuthobeka kwe-petri dish.

3. Kulula ukubheka: I-Petri Dish iveziwe, engalawula ukusakazeka kwamakoloni esitsheni sePetri, esivumelana nokwakhiwa kwamakholoni angashadile futhi kufanelekile ukubonwa kokuhlola;

4. Gwema ukungcoliswa: Ukungenisa kungavimba umphunga wamanzi esitsheni sePetri kusuka ekutholeni isivikelo sesitsha bese wethula amagciwane esikweni eliphakathi nendawo, okwenza ukungcoliswa kweziko eliphakathi nendawo, okuthinta ukukhula kwama-microorganisms ku Isiko Medium.

5. Iqoqo elilungele: Kwesinye isikhathi inhloso yesiko ukuqoqa ama-metabolites ama-bacteria. Kodwa-ke, amanye ama-metabolites ancibilika kalula emanzini. Lapho isidlo se-petri sibekwe kwisembozo, kuzovela amanzi ancishisiwe, abangele amakoloni ukuba akha ama-flakes. Ukubuyisa isidlo se-petri kungenza lula ukuqoqwa kwama-metabolites, nokubala noma ukwahlukana, njll.

6. Gwema ukuqhekeka: Ku-incubator yokupholisa umoya opholile, ungasebenzisa indlela yokufaka isidlo sesiko ukunciphisa ukugeleza komoya ngaphezulu kwamanzi aphakathi, ukuze kunciphise izinga lokuhwamuka kwamanzi aphakathi, ukuze kube lula ukuqhekeka.
