Hanyar tsaftacewa don kafaffen flask na nitrogen
Filashin gyaran nitrogen yana taka muhimmiyar rawa a gwaje-gwajen gyaran nitrogen. Lokacin tsaftacewa, wajibi ne don tabbatar da cewa yana da tsabta kuma baya rinjayar gwaje-gwaje na gaba. Dangane da bayanan tsaftacewa masu dacewa na kayan aikin gyaran nitrogen da ma'anar tsabtace flask na dakin gwaje-gwaje, ana iya amfani da hanyoyin tsaftacewa masu zuwa don tunani:

Fitowar farko
Bayan an gama gwajin, sai a zubar da sauran maganin da ke cikin flask na nitrogen nan da nan, sannan a wanke shi da ruwan famfo don cire mafi yawan abubuwan da suka rage. Wannan na iya hana ragowar abubuwan bushewa da sanya shi da wahalar tsaftacewa, yayin da kuma rage wahalar tsaftacewa na gaba.

Halin tsangwama na kwayoyin halitta
A lokacin aikin distillation, ana iya fitar da wasu mahadi na halitta lokaci guda tare da ammonia, wanda zai iya tsoma baki tare da aunawa. Wasu abubuwa, kamar formaldehyde, ana iya cire su ta tafasa a ƙarƙashin yanayin acidic (pH<1). An appropriate amount of acidic solution (such as dilute hydrochloric acid) can be added to the nitrogen flask, and then boiled to remove possible organic interference. But attention should be paid to controlling the boiling time and temperature to avoid damage to the flask.

Maganin datti mai taurin kai
Idan akwai datti mai taurin kai a cikin kwalbar nitrogen, zaku iya komawa zuwa hanyar tsaftacewa na hular kwalban tururi na mai nazarin nitrogen kuma amfani da 20% glacial acetic acid don magani. A allurar da ya dace na 20% glacial acetic acid a cikin tulun nitrogen, jiƙa ko zafi shi na ɗan lokaci (ana iya daidaita takamaiman lokacin daidai da tsananin datti), sannan a zubar da glacial acetic acid. Wannan hanyar tana amfani da kaddarorin sinadarai na glacial acetic acid don narkewa da cire datti mai taurin kai.

Ƙara ruwa don tsaftacewa
Ƙara 350mL na ruwa a cikin kwanon rufi da gilashin gilashi da yawa don hana ruwa daga tafasa. Bayan shigar da kayan aikin, yi aikin distillation kuma tattara aƙalla 100ml na ruwa. Gilashin gilashi na iya sanya ruwan ya tafasa daidai lokacin aikin dumama, yana guje wa tsalle-tsalle na tashin hankali da watsawa daga cikin flask, yana tabbatar da aminci da kwanciyar hankali na tsarin distillation.

Kurkura da ruwa mai tsabta
A wanke tukwane na nitrogen sau da yawa tare da ruwa mai tsabta, yawanci sau 2-3, don cire sauran abubuwan tsaftacewa da ƙazanta sosai. Yayin kowane kurkura, tabbatar da cewa tsaftataccen ruwa zai iya tuntuɓar dukkan sassan flask ɗin, gami da baki, bango, da ƙasa. A lokacin aikin kurkura, a hankali girgiza flask ɗin don ba da damar ruwa ya fi kyau tsaftace ciki.
