1. Imiyalelo yokusetyenziswa kwezitya zenkcubeko yeseli
Izitya zePetri ziqhele ukwenziwa ngeglasi okanye ngeplastiki, kwaye ziqhele ukusetyenziswa njengezinto ezisetyenziswayo zokulinga ukulima iintsholongwane okanye iinkcubeko zeseli.Ngokubanzi, izitya zeglasi zingasetyenziselwa izinto zezityalo, iinkcubeko ze-microbial, kunye neenkcubeko ezihambelanayo zeeseli zezilwanyana.Izinto zeplastiki zinokuba zizinto ze-polyethylene, ezifanelekileyo kwi-inoculation yebhubhoratri, i-scribing, kunye nemisebenzi yokwahlula iibhaktheriya, kwaye ingasetyenziselwa ukulima izinto zezityalo.Izitya zePetri zibuthathaka, ngoko kufuneka ziphathwe ngononophelo ngexesha lokucoca kunye nokusetyenziswa.Emva kokusetyenziswa, kufuneka zihlanjululwe ngexesha kwaye zigcinwe kwindawo ekhuselekileyo kunye nesigxina.
2. Ukucocwa kwezitya zikaPetri
1.） I-Soak: Gxuma iglasi entsha okanye esetyenzisiweyo ngamanzi acocekileyo ukuthambisa kunye nokunyibilikisa isincamathelisi.Ngaphambi kokusebenzisa i-glassware entsha, yixube ngokulula ngamanzi epompo, kwaye emva koko uyicwilise kwi-5% ye-hydrochloric acid ngobusuku;I-glassware esetyenzisiweyo ihlala iqulethe iiprotheyini ezininzi kunye neoli, okungekho lula ukuxubha emva kokumisa, ngoko kufuneka ifakwe emanzini acocekileyo ngokukhawuleza emva kokusetyenziswa ukuxubha.
2.） Ukuxukuxa: beka i-glassware efakwe emanzini okucoca, kwaye ibrashi ngokuphindaphindiweyo ngebrashi ethambileyo.Musa ukushiya iikona ezifileyo kwaye uthintele umonakalo kwisiphelo somphezulu wezikhongozeli.Geza kwaye uyomise i-glassware ecocekileyo yokukhetha.
3.） I-Pickling: I-Pickling kukucwina iinqanawa ezingentla kwisisombululo sokucoca, esaziwa njengesisombululo se-asidi, ukususa iintsalela ezinokwenzeka kumphezulu weenqanawa ngokusebenzisa i-oxidation eqinile yesisombululo se-asidi.Ukuvunwa akusayi kuba ngaphantsi kweeyure ezintandathu, ubusuku bonke okanye ngaphezulu.Qaphela xa ubeka kwaye uthatha izitya.
4.） Ukuhlanjululwa: Iinqanawa emva kokuxutywa kunye nokukhethwa kufuneka zihlanjululwe ngokupheleleyo ngamanzi.Ingaba iinqanawa zihlanjwe zicocekile emva kokukhethwa kuchaphazela ngokuthe ngqo impumelelo yenkcubeko yeseli.Ukuhlamba ngesandla kwiinqanawa ezikhethiweyo, isitya ngasinye siya kuphinda "sizaliswe ngamanzi - sikhutshwe" ubuncinane ngamaxesha angama-15, kwaye ekugqibeleni sixutywe ngamanzi ahlanjululwayo ngamaxesha angama-2-3, omisiwe okanye omisiwe, kwaye apakishwe ngokulinda.
