Zaren ciki ko zaren waje, yadda ake zabar vials na cryogenic?

2024-03-11


A cikin gwaje-gwajen bincike na kimiyya, cryovials shine kayan aiki mai mahimmanci don adana dogon lokaci na sel, microorganisms, samfurori na halitta, da dai sauransu, suna ba da kwanciyar hankali, yanayin ajiya mai ƙananan zafin jiki don samfurori na halitta don tabbatar da aiki da amincin samfurori.


Duk da haka, idan muka fitar da samfurori da aka adana na dogon lokaci daga firjin mai ƙarancin zafin jiki ko kuma tankin nitrogen na ruwa, sau da yawa ba zato ba tsammani ya firgita da sautin fashewar bututun cryogenic kuma muna fama da kama zuciya. Fashewar bututun cryovial ba kawai zai haifar da asarar samfuran gwaji ba, har ma yana iya haifar da rauni ga ma'aikatan gwaji.


Me ke sa Vial Storage ya fashe? Ta yaya za mu hana faruwar hakan?

Tushen fashewar bututun injin daskarewa shine ragowar nitrogen na ruwa saboda rashin ƙarfi na iska.Lokacin da aka fitar da bututun samfurin don cryopreservation daga cikin tankin nitrogen na ruwa, zafin jiki na cikin bututu yana tashi, ruwa nitrogen a cikin bututu yana vaporize da sauri kuma yana canzawa. daga ruwa zuwa gas. A wannan lokacin, bututun cryovial ba zai iya cire yawan nitrogen a cikin lokaci ba, kuma yana taruwa a cikin bututu. Matsin nitrogen yana ƙaruwa sosai. Lokacin da bututun jikin ba zai iya jure matsanancin matsin lamba da ake samu a ciki ba, zai fashe, yana haifar da fashe bututu.



Na ciki ko na waje?


Yawancin lokaci za mu iya zaɓar bututun juyawa na ciki tare da kyakkyawan iska. Dangane da tsarin murfin bututu da jikin bututu, lokacin da ruwa na nitrogen a cikin bututun cryovial mai jujjuyawar ciki ya vaporize, yana da sauƙin fitarwa fiye da bututun cryovial mai jujjuyawar waje. Haka kuma, bambance-bambancen ƙira na bututun cryogenic mai inganci iri ɗaya zai haifar da bututun cryopreservation mai juyawa na ciki don ƙafe. Ayyukan rufewa na bututun da aka ajiye ya fi na bututun da aka naɗe a waje, don haka ba zai iya haifar da fashewar bututu ba.


Haƙiƙa an ƙera hular waje don daskarewa na inji, yana sa ya zama ƙasa da isa ga samfurin a cikin bututu kuma don haka rage yuwuwar gurɓataccen samfurin. Ana iya sanya shi kai tsaye a cikin firiji don daskarewa, kuma bai dace da ajiyar ruwa na nitrogen ba.

Cotaus cryovial tubemai lamba uku:


1.The tube hula da bututu jiki aka samar daga wannan tsari da kuma model na PP albarkatun kasa, don haka wannan fadada coefficient yana tabbatar da sealing a kowane zafin jiki. Yana iya jure 121 ℃ high zafin jiki da kuma high matsa lamba haifuwa da za a iya adana a -196 ℃ ruwa nitrogen yanayi.


2. An tsara bututun cryo mai juyawa na waje don samfuran daskarewa. Hul ɗin dunƙule mai jujjuyawar waje na iya rage yuwuwar kamuwa da cuta yayin sarrafa samfuran.


3. Cryovials masu juyawa na ciki an tsara su don daskarewa samfurori a cikin lokaci na iskar gas na nitrogen. Gasket ɗin silicone a bakin bututu yana haɓaka hatimin cryovial.


4. Jikin tube yana da babban nuna gaskiya kuma an inganta bangon ciki don sauƙin zubar da ruwa kuma babu saura a cikin samfurin.


5. 2ml Cryovial tube an daidaita shi zuwa daidaitaccen kwandon farantin SBS, kuma ana iya daidaita madaidaicin tube ta atomatik zuwa tashar tashoshi guda ɗaya da tashoshi masu yawa ta atomatik masu buɗewa.

Cotaus uku-in-daya cryogenic vials an samo asali ne daga polypropylene-aji na likita. A halin yanzu iya aiki ne 1.0ml da 2.0ml, da sauran bayani dalla-dalla za a iya musamman bisa ga abokin ciniki bukatun. Tare da kyakkyawan aiki da ƙira mai dacewa, yana ba da mafi kyawun zaɓi ga masu binciken kimiyya. Ko na ciki ne ko na waje, yana iya saduwa da buƙatun gwaji daban-daban kuma ya sa hanyar binciken kimiyyar ku ta zama santsi. Zaɓi Cotaus, sanya sakamakon gwajin ku ya fi fice!
