Kubomi bemihla ngemihla, iitanki ze-nitrogen ezingamanzi zisenokungabonakali njengezinto eziqhelekileyo. Ngoko ke, zisetyenziswa kweziphi iindawo nakwiindawo ezisetyenziswa kuzo iitanki ze-nitrogen ezingamanzi? Inyani kukuba iimeko zokusetyenziswa kweitanki ze-nitrogen ezingamanzi aziyonto ingaqondakaliyo. Ngokuyintloko zisetyenziselwa ukugcinwa nokuhanjiswa kweesampuli zebhayoloji ixesha elide, ezifana neesampuli zegazi, iiseli, isidoda, izicubu, imijovo, iintsholongwane, kunye nolusu oluvela kwizilwanyana, izityalo, okanye abantu, iitanki ze-nitrogen ezingamanzi zifumana indawo yazo kwezolimo, ekufuyeni izilwanyana, ezempilo, kumayeza, ekutyeni, kuphando, nakwamanye amacandelo.
Kwicandelo lezolimo, iitanki ze-nitrogen engamanzi zidlala indima ebalulekileyo kwimisebenzi efana nokuqandisa isidoda semfuyo ukuze sizale, ukugcina iimbumba zezilwanyana kunye nembewu yezityalo ixesha elide ngobushushu obuphantsi. Amaziko emizi-mveliso yemfuyo, kuquka ii-ofisi zelizwe nezengingqi zokukhulisa izilwanyana kunye nezikhululo, zisebenzisa iitanki ze-nitrogen engamanzi ukugcina izinto zemfuza ezifana nesidoda kunye neembumba ezivela kwiihagu, iinkomo, kunye neenkukhu. Kwizolimo zezityalo, ezi tanki zisetyenziswa kwiindawo zokugcina izixhobo zezolimo zokugcina imbewu nokunye.
Kwishishini lezempilo, iitanki ze-nitrogen ezingamanzi ziyimfuneko kakhulu kwiibhanki zebhayoloji zezibhedlele, kwiilebhu eziphambili, nakwiilabhoratri ezahlukeneyo zamasebe, kubandakanya i-oncology, i-pathology, amayeza okuzala, kunye nokuxilongwa. Zisetyenziselwa ukugcinwa nonyango lwamalungu omzimba, ulusu, iisampuli zegazi, iiseli, iintsholongwane, kunye nokufakelwa kwamaqanda ngokwenziwa. Ubukho beetanki ze-nitrogen ezingamanzi buhlala bukhuthaza uphuhliso lwe-cryomedicine yeklinikhi.
Kwishishini lamayeza nokutya, iitanki ze-nitrogen ezingamanzi zisetyenziselwa ukukhenkceza nzulu nokugcina iiseli kunye neesampuli, ukukhupha kwiindlela ezishushu kakhulu, kunye nokugcina ukutya kwaselwandle okusemgangathweni ophezulu. Ezinye zikwasetyenziswa ekudalweni kwe-ayisikhrim ye-nitrogen engamanzi.
Kwicandelo lophando nakwamanye amacandelo, iitanki ze-nitrogen engamanzi ziququzelela iindlela zobushushu obuphantsi, i-ecology yamaqondo obushushu aphantsi, uphando lwe-superconductivity yamaqondo obushushu aphantsi, izicelo zelebhu, kunye neendawo zokugcina ii-germplasm. Umzekelo, kwinkqubo yophando lwezolimo kunye nendawo yokugcina izixhobo zezityalo ezinxulumene nezityalo, iiseli zezityalo okanye izicubu, emva kokufumana unyango lokulwa nokukhenkceza, kufuneka zigcinwe kwindawo ene-nitrogen engamanzi.

Ngokusebenzisa iindlela zokugcina amanzi, ukubeka iiseli kwi-nitrogen engamanzi -196°C ukuze zigcinwe kubushushu obuphantsi, ezi tanki zivumela iiseli ukuba zimise okwethutyana imeko yazo yokukhula, zigcine iimpawu zazo kwaye zinegalelo elikhulu ekukhawuleziseni ukuguqulelwa kweziphumo zophando. Kuzo zonke ezi ndawo zahlukeneyo, iintlobo ezahlukeneyo zeetanki zenitrogen engamanzi zikhanya kakhulu, ziqinisekisa ukhuseleko lweesampuli zebhayoloji.
