Kwimimandla yebhayoloji kunye neyeza, ukukhuselwa kweesampulu zebhayoloji kubaluleke kakhulu.Ngaphandle “kokulala” kwiilabhoratri nasezibhedlele, ezi sampuli zihlala zifuna ukuthuthwa.Ukugcina ngokukhuselekileyo okanye ukuthutha ezi isampulu zixabisekileyo zebhayoloji, ukusetyenziswa kweitanki zenitrogen ezingamanzi kumaqondo obushushu obunzulu obuyi-196 degrees Celsius kubalulekile.
Iitanki zenitrogen ezimanzizihlelwa ngokubanzi zibe ziindidi ezimbini: iitanki zokugcina initrogen engamanzi kunye neitanki zothutho zenitrogen.Amatanki ogcino asetyenziselwa ikakhulu ukugcinwa okumileyo kwenitrogen engamanzi ngaphakathi endlwini, enesakhono esikhulu kunye nemithamo engalungelanga ukuthutha umgama omde kumazwe asebenzayo.
Ngokwahlukileyo, iitanki zothutho zenitrogen ezimanzi zikhaphukhaphu ngakumbi kwaye ziyilelwe ukuhlangabezana neemfuno zothutho.Ukuqinisekisa ukufaneleka kothutho, la matanki afumana uyilo olukhethekileyo lokulwa nokungcangcazela.Ngaphandle kogcino olungatshintshiyo, zingasetyenziselwa ukuthutha ngelixa zizaliswe yinitrogen engamanzi, kodwa amanyathelo okhuseleko kufuneka athatyathwe ukunqanda ungquzulwano olumandla kunye nokungcangcazela.
Umzekelo, iHaier Biomedical's Liquid Nitrogen Biobanking Series iyakwazi ukuthutha iisampulu zebhayoloji kwindawo enzulu yobushushu obuphantsi kakhulu.Uyilo lwayo lwesakhiwo luthintela ngokufanelekileyo ukukhutshwa kwe-nitrogen engamanzi ngexesha lokuthutha.
Kwiimeko apho abasebenzi bafuna ukuthuthwa ngomoya kwexesha elifutshane, i-Biobanking Series ibonisa ukuba ixabiseke kakhulu.Olu ngcelele lubonisa ulwakhiwo olomeleleyo lwe-aluminiyam eneenkcukacha zomthamo ezintlanu ongakhetha kuzo, iwaranti ye-vacuum yeminyaka emi-3, eqinisekisa ukhuseleko olude lweisampulu.Iitanki zinokugcina ii-vials ze-cryogenic okanye i-2ml iityhubhu zokukhenkcisa ezisemgangathweni, zixhotyiswe ngesahluli esikhethekileyo se-mesh yensimbi engenastainless ukwenzela indawo yokugcina kunye nomzimba wolwelo we-nitrogen adsorption.Iziciko ezitshixwayo ezizitshixekayo zongeza umaleko owongezelelweyo wokhuseleko kwisampulu yogcino.
Ngelixa uyilo lweitanki zenitrogen ezingamanzi luququzelela uthutho, amanyathelo okhuseleko amaninzi kufuneka aqwalaselwe kuyo yonke inkqubo yothutho.Okokuqala, kubalulekile ukuqinisekisa ukuba zonke izitshixo zevalvu kwitanki yenitrogen engamanzi zikwimeko efanayo naleyo ngexesha logcino.Ukongezelela, itanki kufuneka ifakwe ngaphakathi kwesakhelo sokhuni kunye ne-cushioning efanelekileyo, kwaye ukuba kuyimfuneko, ikhuselekile kwisithuthi sothutho usebenzisa iintambo zokuthintela nayiphi na intshukumo ngexesha lokuthutha.
Ngaphaya koko, ukusebenzisa izihluzi phakathi kwetanki kubalulekile ukunqanda ukuxhuzula kunye neempembelelo ngexesha lothutho, ngaloo ndlela kuthintelwa iingozi.Xa kulayishwa kwaye kuthululwa amatanki e-nitrogen engamanzi, ingqwalasela kufuneka ihlawulwe ukuze ithintele ukuba ingangqubani.Ukuzirhuqa emhlabeni akukhuthazwa ngamandla, njengoko kunokunciphisa ubomi beetanki zenitrogen ezingamanzi.
