Kutheni le nto i-petri ixhaphakile xa i-microorganisms?

1. Ukucotha i-Exvaporation: Ukulungisa isitya senkcubeko kunokucotha ukunciphisa amanzi aphakathi kwinkcubeko;

2. Ukufikelela ngokulula: Isiciko se-perit sisitya esikhulu kwaye ezantsi incinci. Ukuba ibekwe ngokuthe tye, kulula ukuthabatha isiciko kuphela xa usithatha, esiya kubangela ukubonakaliswa kwenkcubeko kwi-perit kwi-petrium, yehla kwisitya se-petri.

3. Kulula ukuqaphela: Isitya saseTerit singena ngaphakathi, esinokulawula ukusasazeka kwekoloni kwi-perish, elungele ukumiselwa kweekholoni enye kwaye ilungele ukubonwa kovavanyo;

4. Kulumkele ukungcoliseka: UkuPhulaphuli kunokuthintela umphunga wamanzi kwi-petri yesitya kwi-hish esisitya kunye nokubhabha kwi-wicteria kwinkcubeko, ebangela ukungcola kwezenkcubeko, kuchaphazela ukukhula kwee-microorganisms kwi Inkcubeko.

5. Ukuqokelelwa ngokulula: Ngamanye amaxesha injongo yenkcubeko kukuqokelela imetabolites ye-bacteria. Nangona kunjalo, ezinye iimetaboli zinyibilika ngokulula emanzini. Xa isitya se-perit sibekwe kwikhava, amanzi anqatyisiweyo aya kuvela, ebangela iikholoni ukuba afuneke. Ukugubungela isitya se-perit sinokuqhubela phambili ukuqokelelwa kweemetali, kunye nokubala okanye ukwahlukana, njl. Njl.

6. Kulumkele ukuqhekeka: kwi-incubator ye-ventilation enyanzelisiweyo, ungasebenzisa indlela yokugubungela isitya senkcubeko ukunciphisa ukuhamba komoya kumphezulu wamanzi aphakathi, ukuze i-Medium ingekho lula ukuqhekeka.
