Zvitsva kana zvakashandiswa glassware zvinofanira kutanga zvakanyikwa mumvura kuti zvipfave nekunyungudutsa zvigadziriso. Zvitsva zvegirazi zvinofanira kungoshambidzwa nemvura yepombi zvisati zvashandiswa, uye zvakanyura usiku hwose ne5% hydrochloric acid; Zvigadzirwa zvegirazi zvinoshandiswa zvinowanzobatanidzwa nehuwandu hweprotein uye girizi, yakaoma mushure mekunge isiri nyore kukwesha, saka inofanira kunyudzwa pakarepo mumvura yakachena yekukwesha.
1. Nyaya dzinoda kutariswa:
Mushure mekuchenesa uye kuuraya hutachiona kusati kwashandiswa, ingave iyo petri dish yakachena kana kwete ine simba rakakura pabasa, inogona kukanganisa ph yetsika yepakati, kana paine mamwe makemikari, inodzivisa kukura kwebhakitiriya.
Iyo ichangobva kutengwa petri ndiro inofanira kugezwa nemvura inopisa kutanga, uye yobva yanyudzwa muhydrochloric acid solution ine chikamu chechikamu che1% kana 2% kwemaawa akati wandei kubvisa zvinhu zvealkaline zvemahara, uye yozosukurudzwa nemvura yakanyungudutswa kaviri.
Kana iwe uchida kutsika mabhakitiriya, saka shandisa high pressure steam (general 6.8 * 10 5 Pa high pressure steam), sterilization pa120 ℃ for 30min, yakaoma mukamuri tembiricha, kana yakaoma kupisa sterilization, ndiko kuisa petri dish muchoto. , kudzora tembiricha panenge 120 ℃ pasi pemamiriro e2h, unogona kuuraya zino rebhakitiriya.
Zvidiro zvesterilized petri zvinogona kushandiswa chete kupinza uye tsika.
2. Shandisa nzira:
Isa iyo reagent bhodhoro kuti ishandiswe munzvimbo yakakodzera panzvimbo yekushanda, uye sunungura kapu yebhodhoro reagent kuti rishandiswe.
Isa petri ndiro pakati penzvimbo yako yebasa;
Bvisa chivharo chebhodhoro re reagent uye siphon reagent kubva mubhodhoro re reagent ne pipette.
Isa chifukidziro chepetri ndiro shure kwayo;
Nyora zvinyoro nyoro tsika yetsika zvakananga mujinga reimwe divi rendiro;
Isa chivharo pane petri dish;
Isa dhishi parutivi rwayo, uchichenjerera kuti usarega iyo yepakati ichipinda munzvimbo diki pakati pechivharo nepasi;
Bvisa sadza rashandiswa.
