Ukuhlanza izitsha zikaPetrikuyinqubo eyisicefe, kodwa le nqubo ingenza ukuhlola kusebenze kahle.Uma isitsha se-petri singahlanzwa, umhloli udinga ukuchitha isikhathi esiningi ecubungula idatha yokuhlola.Futhi uma isitsha se-petri sihlanzwa kahle, umhloli angenza isilingo ngempumelelo kakhulu.
Ukuhlanzwa mathupha kwezitsha zePetri:
Ngokuvamile, idlula ezinyathelweni ezine zokucwiliswa emanzini, ukukhuhla, ukukha, nokuhlanza.
1. Ukucwiliswa emanzini: Izitsha zengilazi ezintsha noma ezisetshenzisiwe kufanele zifakwe emanzini kuqala ukuze zithambe futhi zihlakaze okunamathiselwe.I-glassware entsha kufanele imane ikhuhle ngamanzi kampompi ngaphambi kokusetshenziswa, bese icwiliswa ubusuku bonke ku-5% hydrochloric acid;i-glassware esetshenzisiwe ivame ukuba namaprotheni amaningi namafutha anamathele kuyo, okungelula ukuwageza ngemva kokoma, ngakho kufanele ifakwe emanzini ahlanzekile ngokushesha ngemva kokusetshenziswa ukukhuhla.
2. Ukukhuhla: Faka i-glassware ecwilisiwe emanzini okugeza bese uyikhuhla ngokuphindaphindiwe ngebhulashi elithambile.Ungashiyi indawo efile futhi uvimbele ukulimala endaweni engaphezulu kwezitsha.Geza futhi usule i-glassware ehlanjululwe yokukhetha.
3. Ukugquma: Ukucwilisa izitsha ezishiwo ngenhla ekhambinini lokuhlanza, elaziwa nangokuthi isixazululo se-asidi, ukuze kukhishwe izinto ezisalayo ezingaba khona ebusweni bezitsha ngokusebenzisa i-oxidation eqinile yengxube ye-asidi.Ukukha akumele kube ngaphansi kwamahora ayisithupha, ngokuvamile ubusuku bonke noma ngaphezulu.Qaphela ngezitsha.
4. Hashaza: Izitsha ngemva kokukhuhla kanye nokucoshwa kufanele zihashazwe ngokugcwele ngamanzi.Ukuthi izitsha zigezwa zihlanzeke ngemuva kokukhetha kuthinta ngqo impumelelo noma ukwehluleka kwesiko lamaseli.Geza izandla izitsha ngemva kokukhetha, futhi isitsha ngasinye kufanele ngokuphindaphindiwe "sigcwaliswe ngamanzi-angenalutho" okungenani izikhathi ezingu-15, futhi ekugcineni sicwiliswe emanzini aphindwe kabili izikhathi ezingu-2-3, zomisiwe noma zomisiwe, futhi zipakishwe ukuze zisetshenziswe kamuva.
Indlela yokuhlanza yokusebenzisa i-XPZilabhorethri glassware washerukuhlanza isitsha se-petri:
Inani lokuhlanza: Izitsha ze-petri ezingu-168 zingahlanzwa ngeqoqo elilodwa
Isikhathi sokuhlanza: imizuzu engama-40 ukuqeda ukuhlanza
Inqubo yokuhlanza: 1. Beka isitsha se-petri esizohlanzwa (esisha singafakwa ngokuqondile emshinini wokuwasha amabhodlela, kanti isitsha se-petri esine-culture medium kufanele sithele ucezu olukhulu lwe-culture medium ngangokunokwenzeka) kubhasikidi ofanayo. wewasha ibhodlela.Ungqimba olulodwa lungahlanza izitsha ze-petri ezingu-56, futhi ngesikhathi esisodwa zingahlanza izitsha ze-petri ezingu-168 ezinezingqimba ezintathu.
2. Vala umnyango womshini wokuwasha amabhodlela, khetha uhlelo lokuhlanza, futhi umshini uzoqala ukuhlanza ngokuzenzakalelayo.Inqubo yokuhlanza ihlanganisa ukuhlanza kwangaphambili - ukugeza okuyinhloko kwe-alkali - ukungathathi hlangothi kwe-asidi - ukuhlanzwa kwamanzi ahlanzekile.
3. Ngemva kokuhlanza, umnyango womshini wokuwasha amabhodlela uyavuleka ngokuzenzakalelayo, ukhiphe isitsha esihlanziwe, bese uthuthela emshinini wokuvala inzalo ukuze uvale inzalo.
Ukuhlanzwa kwezitsha ze-petri kumalabhorethri ezinto eziphilayo kuyingxenye ebaluleke kakhulu yokuphathwa kwelabhorethri.Ukusebenzisa umshini wokuwasha amabhodlela ozishintshayo ngokuphelele esikhundleni sokuhlanza mathupha kungagwema ukungcolisana kusuka ekuthinteni idatha yokuhlolwa, kuvikele impilo yabasebenzi abahlolwayo, futhi kuthuthukise ukusebenza kahle kokuhlolwa.
