Muminda yebiology nekurapa, kuchengetedzwa kwesamples dzemuviri kwakakosha zvikuru. Kunze kwekunge "dzakarara" mumarabhoritari nemuzvipatara, samples idzi dzinowanzoda kutakurwa. Kuti uchengetedze kana kutakura samples idzi dzinokosha dzemuviri zvakachengeteka, kushandiswa kwematangi enitrogen yemvura patembiricha yakadzika kwazvo ye -196 degrees Celsius kwakakosha.
Matangi enitrogen emvuraanowanzoiswa mumhando mbiri: matangi ekuchengetera nitrogen yemvura uye matangi ekutakura nitrogen yemvura. Matangi ekuchengetera anonyanya kushandiswa kuchengetedza nitrogen yemvura isina kugadzika mukati, ine huwandu hwakawanda uye huwandu husina kukodzera kutakurwa kure munzvimbo dzinoshanda.
Kusiyana neizvi, matangi ekutakura ane nitrogen yemvura akareruka uye akagadzirirwa kusangana nezvinodiwa zvekutakura. Kuti ave nechokwadi chekuti akakodzera kutakurwa, matangi aya anogadzirwa nenzira yakasarudzika yekudzivirira kudedera. Kunze kwekuchengetwa kwakasimba, anogona kushandiswa kutakurwa azere nenitrogen yemvura, asi matanho ekudzivirira anofanira kutorwa kudzivirira kubonderana kwakanyanya uye kudedera.
Semuenzaniso, Haier Biomedical's Liquid Nitrogen Biobanking Series inokwanisa kutakura masampuli ezvipenyu munzvimbo dzakadzika dzekupisa kwakanyanya. Magadzirirwo ayo ezvimiro zvinobudirira anodzivirira kuburitswa kwenitrogen yemvura panguva yekufambisa.
Mumamiriro ezvinhu apo vashandi vanoda kutakurwa nendege kwenguva pfupi, Biobanking Series inobatsira zvikuru. Iyi nhevedzano ine chimiro chakasimba chealuminium chine mavhoriyamu mashanu ekusarudza kubva, waranti yemakore matatu ye vacuum, ichivimbisa kuchengetedzeka kwenguva refu kwesampuli. Matangi anogona kuchengetedza mavhari e cryogenic kana machubhu echando e2ml, ane mesh separator yesimbi isina ngura yekuchengetedza uye body yemvura inonyungudutsa nitrogen. Zvivharo zvinokiyiwa zvinogona kuvharwa zvinowedzera imwe layer yekuchengetedzwa kwekuchengetera sampuro.
Kunyange hazvo dhizaini yematangi enitrogen yemvura ichibatsira kutakurwa, matanho akati wandei ekuchengetedza anofanira kuteverwa mukuita kwese kwekutakura. Chekutanga, zvakakosha kuve nechokwadi chekuti mavharuvhu ese ari patangi renitrogen yemvura ari mumamiriro akafanana neapo panguva yekuchengetwa. Pamusoro pezvo, tangi rinofanira kuiswa mukati mefuremu yehuni ine cushion yakakodzera, uye kana zvichidikanwa, rakabatanidzwa kumota yekutakura uchishandisa tambo kudzivirira chero kufamba panguva yekutakura.
Uyezve, kushandisa mafiller pakati pematangi kwakakosha kudzivirira kusvetukirana uye kukanganiswa panguva yekufambisa, nokudaro kudzivirira tsaona. Pakutakura nekuburitsa matangi enitrogen yemvura, kungwarira kunofanira kupihwa kudzivirira kuti asaroverane. Kuadhonza pasi hakukurudzirwi zvakanyanya, sezvo kunogona kuderedza hupenyu hwematangi enitrogen yemvura.
