Don adana ƙwayoyin halitta masu mahimmanci na tsawon lokaci, cryogenic Dewar kwalba tsari ne wanda ke samar da daidaitaccen yanayin yanayin zafin jiki don kiyaye rayuwar ƙwayoyin halitta masu rauni. Cryogenic Dewar wani nau'in jirgin ruwa ne mara matsi, wanda aka kera shi musamman kuma aka kera shi, wanda zai iya jure kayan da suka hada da nitrogen mai ruwa. Ruwan nitrogen ba shi da ƙamshi, mara launi, mara dandano, kuma ba mai tayar da hankali ba; sabili da haka, ba shi da kaddarorin gargaɗi kuma yana buƙatar kulawa da hankali. A ƙarancin zafin jiki na - 196 liquid, nitrogen mai ruwa ana ɗaukarsa azaman ruwa ne na cryogenic, wanda za'a iya amfani dashi don adana ƙananan ƙwayoyin rayuwa.

saboda kasancewar akwai sinadarin nitrogen a cikin ruwa, zai yiwu a samu nasarar magance matsalar. Ta hanyar adana dogon lokaci na ƙwayoyin sel, kyallen takarda da sauran samfuran a cikin kwalaben Dewar, ana iya ci gaba da hanyoyin likita da bincike.

masu zuwa matakai guda biyar ne don kare dattin daddawa da abinda ke ciki:

1. Yi amfani da tsarin saka idanu na zazzabi mai dogaro. Don hana duk wani tasirin kwayar halitta wanda zai iya haifar da lalacewar kwayar halitta, ya kamata a kiyaye samfuran halittu masu saurin yanayi a yanayin yanayin zafi sosai. 2.Rashin zafin jiki na ƙarancin rai (misali - 196? C) na iya rayar da ƙayyadaddun ƙwayoyin rayuwa. Hanya ingantacciya don tabbatar da lafiyar ƙarancin zafin jiki Dewar abinda ke ciki da kiyaye ƙarancin zafin jiki shine aiwatar da ingantaccen ruwa mai lura da yanayin zafin yanayin nitrogen.
3..Ka rage yanayin zafi Dewar a tsaye a kowane lokaci. Yakamata a kiyaye dewars na Cryogenic a kowane lokaci don tabbatar da ajiya mai aminci. Zubar da dewar ko sanya shi a gefensa na iya haifar da nitrogen mai ruwa ya malala. Lalacewa ga dewar ko duk wani abu da aka adana a ciki na iya faruwa.
4..Babu yadda za'ayi amfani dashi. Yin amfani da ƙarfi yana iya haifar da mummunan lahani ga kwalaben Dewar na ciki da kuma abubuwan da ke ciki. Sauke kwalban Dewar, juya shi a gefensa, kuma ku sha wahala mai ƙarfi da jijjiga, wanda na iya haifar da rashi ko cikakkiyar ɓacewa. Tsarin ruɓin iska yana rage nauyin canja wurin zafi na ruwa mai ƙanshi kuma yana kiyaye dewar a ƙarancin zafin jiki koyaushe. Aramin yanayin zafin jiki na iya haɗuwa da mahimmancin buƙatar ƙananan zafin jiki.
5..Kewa na'urar tsabtace ta bushe. Ya kamata a sanya na'urar a wuri mai tsabta da bushe. Danshi, sinadarai, masu tsabtace tsabta da sauran abubuwa na inganta lalata kuma yakamata a cire su kai tsaye. A sauƙaƙe tsabtace kwalban Dewar na ruwa da ruwa ko mai laushi mai tsabta kuma ya bushe sosai don hana lalata ƙarfen ƙarfe. Lalacewa ga kayan da aka yi amfani da su don yin dusar na iya sa abin da aka adana cikin haɗari.
Rike isasshen iska. Bai kamata a rufe ko toshe mashigar kowane Dewar cryogenic ba don hana tsangwama tare da fitar da iskar gas. Ba a matsawa Dewars ba, don haka rashin isasshen iska na iya haifar da matsi mai yawa. Wannan na iya haifar da kwalban Dewar ya fashe kuma ya zama haɗarin aminci ga ma'aikata da kwayoyin da aka adana.
