Eminyakeni yamuva nje, ama-biobank abelokhu edlala indima ebaluleke kakhulu ocwaningweni lwesayensi. Imishini yokugcina esezingeni eliphezulu enokushisa okuphansi ingaqinisekisa ukuphepha kanye nomsebenzi wamasampula futhi isize abacwaningi ekwenzeni kangcono ucwaningo oluhlukahlukene lwesayensi ngokuhlinzeka ngendawo yokugcina yobungcweti nephephile yamasampula ezinto eziphilayo.
Amathangi e-nitrogen aqukethe uketshezi asetshenziswe ukugcina amasampula isikhathi eside. Agcina amasampula ekushiseni okuphansi okungu--196 ℃ adalwe ngesisekelo sesimiso sokufakwa kwe-vacuum ngemuva kokuba amasampula epholile. Kunezindlela ezimbili zamathangi e-nitrogen aqukethe uketshezi zokugcina amasampula: ukugcinwa kwesigaba soketshezi kanye nokugcinwa kwesigaba somusi. Uyini umehluko phakathi kwalawa amabili?
1. Isicelo
Amathangi e-nitrogen esigaba soketshezi asetshenziswa kakhulu emalabhorethri, ekufuyweni kwezilwane, kanye nasemkhakheni wokucubungula.
Amathangi e-nitrogen ewuketshezi esigaba somhwamuko asetshenziswa kakhulu kuma-biobank, emithini yezokwelapha kanye nasensimini yokunakekelwa kwempilo.
2. Isimo Sesitoreji
Esigabeni somusi, amasampula agcinwa ngokuhwamuka nokupholisa i-nitrogen ewuketshezi. Izinga lokushisa lokugcina lisukela phezulu kuya phansi endaweni yokugcina isampula. Uma kuqhathaniswa, esigabeni soketshezi, amasampula agcinwa ngqo ku-nitrogen ewuketshezi ku--196 °C. Amasampula kufanele acwiliswe ngokuphelele ku-nitrogen ewuketshezi.

Ngaphezu kwalo mehluko, amazinga okuhwamuka kwe-nitrogen ewuketshezi ahlukene. Ngokuvamile, izinga lokuhwamuka kwe-nitrogen ewuketshezi lincike kububanzi bethangi le-nitrogen ewuketshezi, imvamisa yabasebenzisi abavula isivalo, inqubo yokukhiqiza, ngisho nokushisa okuzungezile kanye nomswakama. Kodwa ngokwemvelo, ubuchwepheshe obuthuthukisiwe be-vacuum kanye nokushisa obusetshenziswa ekukhiqizeni amathangi e-nitrogen ewuketshezi buyisihluthulelo sokuqinisekisa ukusetshenziswa okuphansi kwe-nitrogen ewuketshezi.
Umehluko omkhulu phakathi kwalokhu okubili usendleleni amasampula agcinwa ngayo. Uma egcinwe esigabeni somusi, amasampula awaxhumani ngqo ne-nitrogen ewuketshezi, okuvimbela amagciwane ekungcoliseni amasampula. Kodwa-ke, izinga lokushisa lokugcina alikwazi ukufika ku--196°C. Esigabeni soketshezi, yize amasampula angagcinwa cishe ku--196°C, ithubhu yokulondoloza amanzi ayizinzile. Uma ithubhu yokulondoloza amanzi ingavaliwe kahle, i-nitrogen ewuketshezi izongena ethubeni. Lapho ithubhu lokuhlola likhishwa, ukuguquguquka kwe-nitrogen ewuketshezi kuzoholela ekucindezelweni okungalingani ngaphakathi nangaphandle kwethubhu lokuhlola futhi ithubhu lizoqhuma ngenxa yalokho. Ngakho-ke, ubuqotho besampula buzolahleka. Lokhu kusikisela ukuthi kukhona kokubili izinzuzo nezingozi zendlela ngayinye.
Ungalinganisa Kanjani Phakathi Kwababili?
Uchungechunge lwe-biobank lwe-Haier Biomedical Liquid Nitrogen Storage System lwenzelwe kokubili ukugcinwa koketshezi kanye nesigaba somusi.
Ihlanganisa izinzuzo zokugcina isitoreji sesigaba somusi kanye nesitoreji sesigaba soketshezi, eklanyelwe ubuchwepheshe obuthuthukisiwe be-vacuum kanye ne-insulation ukuqinisekisa ukuphepha kwesitoreji kanye nokufana kwezinga lokushisa ngenkathi kunciphisa ukusetshenziswa kwe-nitrogen ewuketshezi. Umehluko wokushisa wendawo yonke yokugcina awudluli ku-10°C. Ngisho nasesigabeni somusi, izinga lokushisa lokugcina eduze kwaphezulu kweshalofu liphansi njengo--190°C.
Uchungechunge lwe-Biobank Lokugcina Isitoreji Esibanzi
Ngaphezu kwalokho, izinzwa zokushisa ezinembile kakhulu kanye nezinga loketshezi zisetshenziselwa ukuqinisekisa ukunemba. Yonke idatha namasampula zivikelwe uhlelo lokulawula ukufinyelela oluvikelekile. Lezi zinzwa ziqapha izinga lokushisa kanye nolwazi lwezinga loketshezi ethangini le-nitrogen eliwuketshezi ngesikhathi sangempela, ngakho-ke uketshezi olusethangini lungagcwaliswa ngokuzenzakalelayo ukuze kudalwe izimo zokugcina isampula eziphephile.
