Kwimiba yebhayoloji kunye neyeza, ukukhuselwa kweesampuli zebhayoloji kubaluleke kakhulu. Ngaphandle kokuba "zilele" kwiilebhu nakwizibhedlele, ezi sampuli zihlala zifuna ukuthuthwa. Ukugcina okanye ukuhambisa ngokukhuselekileyo ezi sampuli zixabisekileyo zebhayoloji, ukusetyenziswa kweetanki ze-nitrogen ezingamanzi kumaqondo obushushu aphantsi kakhulu angama--196 degrees Celsius kubaluleke kakhulu.
Iitanki zenitrogen ezingamanzingokubanzi zahlulwe zibe ziintlobo ezimbini: iitanki zokugcina i-nitrogen engamanzi kunye neetanki zokuthutha i-nitrogen engamanzi. Iitanki zokugcina zisetyenziselwa kakhulu ukugcinwa kwe-nitrogen engamanzi ngaphakathi, ezinomthamo omkhulu kunye nomthamo ongafanelekanga kuthutho olude kwiimeko zokusebenza.
Ngokwahlukileyo koko, iitanki zokuthutha i-nitrogen engamanzi zikhaphukhaphu kwaye zenzelwe ukuhlangabezana neemfuno zothutho. Ukuqinisekisa ukuba zifanelekile ukuthuthwa, ezi tanki ziphantsi koyilo olukhethekileyo lokulwa nokungcangcazela. Ngaphandle kokugcinwa ngokuzenzekelayo, zingasetyenziselwa ukuthuthwa ngelixa zizaliswe yi-nitrogen engamanzi, kodwa kufuneka kuthathwe amanyathelo okhuseleko ukuze kuthintelwe ukungqubana okukhulu kunye nokungcangcazela.
Umzekelo, i-Liquid Nitrogen Biobanking Series yeHaier Biomedical iyakwazi ukuthutha iisampuli zebhayoloji kwiindawo ezishushu kakhulu. Uyilo lwayo lwesakhiwo luthintela ngokufanelekileyo ukukhutshwa kwe-nitrogen engamanzi ngexesha lokuthuthwa.
Kwiimeko apho abasebenzi bafuna ukuthuthwa ngomoya okwethutyana, i-Biobanking Series ixabiseke kakhulu. Olu luhlu lunesakhiwo se-aluminium esomeleleyo esineemfuno ezintlanu zomthamo onokukhetha kuzo, iwaranti ye-vacuum yeminyaka emi-3, eqinisekisa ukhuseleko olude lweesampuli. Iitanki zinokugcina ii-cryogenic vials okanye iityhubhu zokuqandisa eziqhelekileyo ze-2ml, ezixhotyiswe nge-stainless-steel mesh separator ekhethekileyo yokugcina kunye nomzimba we-liquid nitrogen adsorption. Izivalo ezitshixwayo ezikhethiweyo zongeza umaleko owongezelelweyo wokhuseleko kwindawo yokugcina isampuli.
Nangona uyilo lweetanki ze-nitrogen engamanzi lunceda ekuthuthweni, kufuneka kulandelwe amanyathelo okhuseleko amaninzi kuyo yonke inkqubo yokuthutha. Okokuqala, kubalulekile ukuqinisekisa ukuba zonke ii-valve switches kwitanki ye-nitrogen engamanzi zikwimeko efanayo naxa igcinwa. Ukongeza, itanki kufuneka ibekwe ngaphakathi kwisakhelo somthi esine-cushion efanelekileyo, kwaye ukuba kuyimfuneko, ibotshelelwe kwisithuthi sokuthutha kusetyenziswa iintambo ukuthintela nayiphi na intshukumo ngexesha lokuthutha.
Ngaphezu koko, ukusebenzisa izizalisi phakathi kwamatanki kubalulekile ukuthintela ukuxinana kunye neempembelelo ngexesha lokuthuthwa, ngaloo ndlela kuthintelwe iingozi. Xa ulayisha kwaye ukhupha iitanki ze-nitrogen engamanzi, kufuneka kuqwalaselwe ukuba zingangqubani. Ukuzirhuqa emhlabeni akukhuthazwa kakhulu, kuba kunokunciphisa ubomi beetanki ze-nitrogen engamanzi.
