Endaweni yangempela yegumbi lokupheka, ithuluzi lokulinganisa lokukhiqiza ibhodlela lamandla, ukuhlanzeka kwalo kungalinganiswa ngokuqondile futhi umphumela wangempela wokuhlola cishe uqinisekile. Kodwa-ke, ngemva kokusetshenziswa, ukuhlolwa kwamakhemikhali odongeni lwangaphakathi lwebhodlela kuhlala, ngakho-ke akunakwenzeka ukudaya umkhiqizo, futhi akunakwenzeka ukudala umkhiqizo wangempela ngemva kokuwusebenzisa. Sicela uqonde ukuthi lokhu kuyinkinga, futhiilebhuiwasha glassware ukuhlanzaumthamo kanye nendlela yokuhlanza ibhodlela kuzenzakalela ngokuphelele.

Ukuhlanza ibhodlela ukuhlangabezana nezincazelo ezahlukene

Iokuzenzakalelayo ngokugcweleukugeza ingilazir ingakwazi ukuphatha kalula imisebenzi yokuhlanza amabhodlela evolumu anamandla ahlukene ukusuka ku-5ml kuya ku-5L. Ekuhlanzweni okukodwa, ingakwazi ukuhlanganisa amabhodlela evolumu angama-264 25ml, amabhodlela evolumu angama-176 50ml, amabhodlela evolumu angama-144 100ml, kanye namabhodlela evolumu angama-72 250ml (isibonelo sevolumu yokuhlanza iwasha yamabhodlela ekabili), amboze imininingwane ejwayelekile yaselabhorethri, iqinisekisa ukuthi zonke izingxenye zemishini yokuhlola zingahlanzwa ngempumelelo.

Ukuhlanza nokomisa ngesinyathelo esisodwa

Isikhathi ukusebenza kahle, ikakhulukazi elabhorethri. Iothomathikhi ngokugcwele ibhodlela washerkuthatha imizuzu engu-40 kuphela ukuwasha okukodwa, okulandelwa yisikhathi sokumisa esiyimizuzu engu-20, futhi yonke inqubo kusukela ekuwashweni kuya komisweni ingaqedwa phakathi nehora. Lokhu kuvumela abacwaningi ukuthi bafake amaflaski evolumu ahlanziwe esivivinyweni esilandelayo ngokushesha okukhulu, ukuthuthukisa ukusebenza kahle okuphelele komsebenzi.

Kulula ukwenza kahle inqubo yokuhlanza

Ukusebenzisa i- umshini wokuwasha amabhodlela othomathikhi ngokugcwele, abacwaningi bangaqedela umsebenzi wokuhlanza ngezinyathelo ezimbalwa nje ezilula: okokuqala, faka i-volumetric flask esetshenzisiwe ngomlomo obheke phansi emshinini wokuwasha amabhodlela, futhi usebenzise umsebenzi wokuvula nokuvala umnyango ozenzakalelayo ukuze uvale umnyango kalula; bese, ngokusebenzisa isixhumi esibonakalayo sokukhetha esakhelwe ngaphakathi, khetha uhlelo olujwayelekile noma uhlelo lwangokwezifiso ngokwezidingo. Lesi sakamuva sivumela abasebenzisi ukuthi balungise ngokukhululekile imingcele yokuhlanza ukuze bahlangabezane nezidingo ezikhethekile zokuhlanza; ke, qala uhlelo lokuhlanza, futhi umshini uqala ngokuzenzakalelayo inqubo yokuhlanza ngaphandle kokungenelela komuntu; lapho ukuhlanza sekuqediwe, umshini ukhipha isikhumbuzi se-beep, i-hatch ivula ngokuzenzakalelayo futhi iqedele uhlelo lokukhipha ukushisa ukuze kuvinjelwe ukusha, futhi abacwaningi bangakwazi ukukhipha ngokuphepha i-volumetric flask ehlanzekile.

Ukufafaza kwesayensi ukuze kuqinisekiswe umphumela wokuhlanza

Umshini wokuwasha amabhodlela ozenzakalelayo ngokuphelele usebenzisa ubuchwepheshe bokuhlanza isifutho sesayensi. Ngohlelo lwesifutho kanye nohlelo lokuhlanza oluthuthukisiwe, luqinisekisa ukuthi lonke udonga lwangaphakathi nolwangaphandle lweflask yevolumu lungahlanzwa ngempumelelo, lususe izinsalela zama-reagent amakhemikhali, futhi luqinisekise ukunemba nokuthembeka kwemiphumela yokuhlola.
