Petri Dish

Petri Dish---Uyilo olucokisekileyo kunye noVeliso oluchanekileyo

1.Ipolystyrene ephuma kumazwe angaphandle ekumgangatho ophezulu isetyenziswa njengemathiriyeli ekrwada.Umphezulu wesitya sePetri ugudile kwaye ukucaca ngokubanzi kuphezulu, okukulungele ukukhula kunye nokwandiswa kweeseli ezinamathele eludongeni.

I-2.I-sterilized nge-ethylene oxide ukuqinisekisa ubunyumba, ithatha ukupakishwa kohlobo lweenyembezi lwamazwe ngamazwe.

3.Ifanelekile kwiseli, inkcubeko yebhaktheriya, uvavanyo lokuva ubunzima kwiziyobisi, njl. njl.

Inkqubo yokucoca

Ngokuqhelekileyo, kukho amanyathelo amane: ukumanzisa, ukuxubha, ukukha, kunye nokucoca.

1. Ukufunxwa: iiglasi ezintsha okanye ezisetyenzisiweyo kufuneka zifakwe emanzini acacileyo kuqala ukuze zithambe kwaye zinyibilikise iziqhotyoshelo.I-glassware entsha kufuneka ihlanjwe ngokulula ngamanzi ompompo ngaphambi kokusetyenziswa, kwaye emva koko ifakwe ubusuku bonke nge-5% ye-hydrochloric acid;I-glassware esetyenzisiweyo ihlala iqulethe iprotheni eninzi kunye negrisi, okungekho lula ukuyixubha emva kokumisa, ngoko kufuneka ifakwe ngokukhawuleza emanzini acocekileyo ukuxubha emva kokusetyenziswa.

2. Ukuxukuxa: faka i-glassware efakwe emanzini kunye ne-brush ngokuphindaphindiweyo ngebrashi ethambileyo.Musa ukushiya iikona ezifileyo, kwaye uthintele umonakalo kwisiphelo somphezulu wezixhobo.Geza kwaye uyomise i-glassware ehlanjiweyo yokukhetha.

3. I-Pickling: i-Pickling kukuntywilisela iinqanawa ezingentla kwisisombululo sokucoca, esikwaziwa ngokuba yisisombululo se-asidi, kunye nokususa izinto ezinokwenzeka eziseleyo kumphezulu weenqanawa ngokusebenzisa i-oxidation eqinile yesisombululo se-asidi.Ukuvunwa kufuneka kungabi ngaphantsi kweeyure ezintandathu, ngokuqhelekileyo ubusuku okanye ngaphezulu.Qaphela xa ubeka kwaye uthatha izitya.

4. Ukuhlamba: izitya emva kokuxutywa kunye nokuchola kufuneka zihlanjwe ngokupheleleyo ngamanzi.Nokuba izitya zihlanjwe zicoceke emva kokuchola kuchaphazela ngqo impumelelo okanye ukungaphumeleli kwenkcubeko yeseli.Emva kokuhlamba izandla izitya ezifakwe emanzini, isitya ngasinye kufuneka siphindwe "sizaliswe ngamanzi" ubuncinane amaxesha angama-15, kwaye ekugqibeleni sifakwe emanzini ahlanjululwayo ngamaxesha angama-2-3, omisiwe okanye omisiwe kwaye apakishwe ngokulinda.

 

Icwecwe leNkcubeko

1.Yamkela iteknoloji yonyango oluphezulu kunye nenkqubo yokwenziwa kwezixhobo zepolymer ezinobushushu obuphantsi.

2.Ukuhlanganiswa kwekhava kunye ne-plate ephantsi kunobunzima obuphakathi, obulungele ukungena komoya kunye nokuthintela ukungcoliseka kweplate yenkcubeko okanye ukukhuphuka kolwelo.

3.Iinkcukacha ezahlukeneyo zidibana neenkcubeko ezahlukeneyo zeeseli.
