Ukuhlanza izitsha zePetrikuyinqubo eyisicefe, kodwa le nqubo ingenza ukuhlolwa kusebenze kahle kakhulu. Uma isitsha se-petri singahlanzwa, umhloli kudingeka achithe isikhathi esiningi ecubungula idatha yokuhlola. Futhi uma isitsha se-petri sihlanzwa kahle, umhloli angenza ukuhlolwa kahle kakhulu.
Ukuhlanza izitsha zePetri ngesandla:
Ngokuvamile, kudlula ezinyathelweni ezine zokucwilisa, ukuhlafuna, ukukhuhla, kanye nokuhlanza.
1. Ukucwilisa: Izingilazi ezintsha noma ezisetshenzisiwe kufanele zicwiliswe emanzini kuqala ukuze zithambe futhi zincibilikise okunamathiselwe. Izingilazi ezintsha kufanele zihlanzwe ngamanzi ompompi ngaphambi kokusetshenziswa, bese zicwiliswa ubusuku bonke ku-5% hydrochloric acid; izingilazi ezisetshenzisiwe zivame ukuba namaprotheni amaningi namafutha anamathiselwe kuzo, okungelula ukuzigeza ngemva kokomisa, ngakho-ke kufanele zicwiliswe emanzini ahlanzekile ngokushesha ngemva kokusetshenziswa ukuze zihlanzwe.
2. Ukukhuhla: Faka izingilazi ezicwiliswe emanzini anensipho bese uzikhuhla ngokuphindaphindiwe ngebhulashi elithambile. Ungashiyi isikhala esifile futhi uvimbele umonakalo ebusweni bezitsha. Geza bese womisa izingilazi ezihlanziwe ukuze zifakwe emanzini anosawoti.
3. Ukuqoqwa: Ukuqoqwa kusho ukucwilisa izitsha ezishiwo ngenhla esixazululweni sokuhlanza, esaziwa nangokuthi isixazululo se-asidi, ukuze kususwe izinto ezingaba khona ezisele ebusweni bezitsha ngokusebenzisa i-oxidation enamandla yesisombululo se-asidi. Ukuqoqwa akufanele kube ngaphansi kwamahora ayisithupha, ngokuvamile ubusuku bonke noma ngaphezulu. Qaphela izitsha.
4. Hlanza: Izitsha ngemva kokuzihlanza nokuzifaka emanzini kumele zihlanzwe ngamanzi ngokuphelele. Ukuthi izitsha zihlanzwe kahle yini ngemva kokuzifaka emanzini kuthinta ngqo impumelelo noma ukwehluleka kokukhuliswa kwamaseli. Geza izitsha ngesandla ngemva kokuzifaka emanzini, futhi isitsha ngasinye kumele siphinde “sigcwaliswe ngamanzi singenalutho” okungenani izikhathi ezingu-15, bese ekugcineni sicwiliswe emanzini acwecwe kabili izikhathi ezingu-2-3, somiswe noma somiswe, bese sipakishwa ukuze sisetshenziswe kamuva.

Indlela yokuhlanza yokusebenzisa i-XPZumshini wokuwasha ingilazi webhubhoratriukuhlanza isitsha se-petri:
Inani lokuhlanza: Izitsha ze-petri eziyi-168 zingahlanzwa ngebhetshi elilodwa
Isikhathi sokuhlanza: imizuzu engama-40 ukuqeda ukuhlanza
Inqubo yokuhlanza: 1. Beka isitsha se-petri esizohlanzwa (esisha singafakwa ngqo emshinini wokuwasha amabhodlela, bese isitsha se-petri esinomshini wokuwasha kufanele sithulule ingxenye enkulu yemishini yokuwasha amabhodlela ngangokunokwenzeka) kubhasikidi ofanayo wesitsha sokuwasha amabhodlela. Isendlalelo esisodwa singahlanza izitsha ze-petri ezingu-56, futhi kanye singahlanza izitsha ze-petri ezingu-168 ezinezingqimba ezintathu.
2. Vala umnyango womshini wokuwasha amabhodlela, khetha uhlelo lokuhlanza, bese umshini uzoqala ukuhlanza ngokuzenzakalelayo. Inqubo yokuhlanza ifaka phakathi ukuhlanza kwangaphambilini - ukuwasha okuyinhloko kwe-alkali - ukungathathi hlangothi kwe-asidi - ukuhlanza ngamanzi ahlanzekile.
3. Ngemva kokuhlanza, umnyango womshini wokuwasha amabhodlela uvula ngokuzenzakalelayo, ukhiphe isitsha sokukhulisa esihlanziwe, bese uthuthela emishinini yokubulala amagciwane ukuze kubulawe amagciwane.
Ukuhlanzwa kwezitsha ze-petri ezindaweni zokucwaninga zezinto eziphilayo kuyingxenye ebaluleke kakhulu yokuphathwa kwelebhu. Ukusebenzisa umshini wokuwasha amabhodlela ozenzakalelayo ngokuphelele esikhundleni sokuhlanza ngesandla kungagwema ukungcoliswa okuhlukahlukene ekuthinteni idatha yokuhlola, kuvikele impilo yabasebenzi bokuhlola, futhi kuthuthukise ukusebenza kahle kokuhlola.
