Kwiminyaka yakutshanje, iibhanki zebhayoloji bezidlala indima ebaluleke ngakumbi kuphando lwesayensi.Izixhobo zokugcina ezikumgangatho ophantsi wobushushu zinokuqinisekisa ukhuseleko kunye nomsebenzi weesampulu kwaye uncedise abaphandi ekuqhubeni ngcono uphando lwezenzululwazi olwahlukeneyo ngokubonelela ngobuchwephesha kunye nendawo yokugcina ekhuselekileyo yeesampulu zebhayoloji.
Iitanki zenitrogen ezimanzi zisetyenziselwe ukugcina iisampuli ixesha elide.Bagcina iisampulu kwiqondo lobushushu eliphantsi le--196 ℃ elenziwe ngokwesiseko somgaqo wokugquma ivacuum emva kokuba iisampuli zipholiswe kwangaphambili.Zimbini iindlela zolwelo lweitanki zenitrogen zokugcina iisampuli: ugcino lwesigaba solwelo kunye nogcino lwesigaba somphunga.Yintoni umahluko phakathi kwezi zimbini?
1. Isicelo
Iitanki zenitrogen yesigaba solwelo zisetyenziswa ikakhulu kwiilebhu, ukufuywa kwezilwanyana, nakwicandelo lokulungisa.
Iitanki zenitrogen yolwelo lwesigaba somphunga zisetyenziswa ikakhulu kwiibhanki zebhayoloji, kumayeza, nakwindawo yokhathalelo lwempilo.
2. Isimo soGcino
Kwinqanaba lomphunga, iisampulu zigcinwa ngokuba ngumphunga kunye nokupholisa ulwelo lwenitrogen.Ubushushu bokugcina buvela phezulu ukuya ngasezantsi kwindawo yokugcina isampuli.Ngokuthelekisa, kwisigaba solwelo, iisampuli zigcinwa ngokuthe ngqo kwi-nitrogen engamanzi kwi -196 °C.Iisampulu kufuneka zintywiliselwe ngokupheleleyo kwinitrogen engamanzi.

Ukongeza kulo mahluko, amazinga omphunga wenitrogen engamanzi kwezi zimbini nawo ahlukile.Ngokubanzi, izinga lokumka komphunga lwenitrogen yolwelo lixhomekeke kububanzi betanki yenitrogen engamanzi, amaxesha amaninzi abasebenzisi abavula isiciko, inkqubo yokuvelisa, kunye nobushushu obuthile kunye nokufuma.Kodwa ngokwendalo, itekhnoloji yokucoca ephucukileyo kunye netekhnoloji yokugquma esetyenziswa ekwenzeni itanki yenitrogen engamanzi sisitshixo sokuqinisekisa ukusetyenziswa okuphantsi kwenitrogen engamanzi.
Owona mahluko mkhulu phakathi kwezi zimbini ulele kwindlela iisampulu ezigcinwa ngayo.Igcinwe kwisigaba somphunga, iisampulu aziqhagamshelani ngokuthe ngqo ne-nitrogen engamanzi, ukuthintela iibhaktheriya ekungcoliseni iisampuli.Nangona kunjalo, iqondo lokushisa alikwazi ukufikelela kwi -196 ° C.Kwinqanaba le-liquid, nangona iisampulu zingagcinwa kwi--196 ° C, ityhubhu ye-cryopreservation ayizinzile.Ukuba ityhubhu ye-cryopreservation ayivalwanga kakuhle, initrogen engamanzi iya kungena kumbhobho.Xa ityhubhu yokuvavanya ikhutshwe, i-volatilization ye-nitrogen engamanzi iya kukhokelela kuxinzelelo olungalinganiyo ngaphakathi nangaphandle kombhobho wokuvavanya kwaye ityhubhu iya kuqhuma ngenxa yoko.Ke ngoko, ingqibelelo yesampulu iya kulahleka.Oku kuphakamisa ukuba kukho zombini izinto ezilungileyo kunye nezibi kwindlela nganye.
Ungabetha njani iBalance phakathi kwezi Zimbini?
Uluhlu lwe-biobank ye-Haier Biomedical Liquid Storage System ye-Nitrogen yenzelwe ukugcinwa kwesigaba solwelo kunye nomphunga.
Idibanisa iingenelo zombini kwisigaba somphunga kunye nokugcinwa kwesigaba solwelo, eyilwe ngevacuum ephucukileyo kunye nobuchwepheshe bokugquma ukuqinisekisa ukhuseleko logcino kunye nokufana kobushushu ngelixa kuncitshiswa ukusetyenziswa kwenitrogen engamanzi.Umahluko weqondo lobushushu kwindawo yonke yokugcina awudluli kwi-10°C.Nakwisigaba somphunga, iqondo lobushushu lokugcina kufutshane nomphezulu weshelufu liphantsi njenge -190°C.

Ukongeza, ubushushu obuchanekileyo kunye nezinzwa zenqanaba lolwelo zisetyenziselwa ukuqinisekisa ukuchaneka.Zonke iinkcukacha kunye neesampuli zikhuselwe yinkqubo yokulawula ukufikelela ekhuselekileyo.Ezi zivamvo zihlola ubushushu kunye nolwazi lwenqanaba lolwelo kwitanki yenitrogen engamanzi ngexesha lokwenyani, kwaye ke ulwelo olukwitanki lunokuzaliswa ngokuzenzekelayo ukwenza ezona meko zikhuselekileyo zokugcina isampulu.
