Mu nkhani za sayansi ya zamoyo ndi zamankhwala, kuteteza zitsanzo za zamoyo n'kofunika kwambiri. Kupatula kukhala "ogona" m'ma laboratories ndi m'zipatala, zitsanzozi nthawi zambiri zimafunika kunyamulidwa. Kuti musunge kapena kunyamula zitsanzo zamtengo wapatali za zamoyozi mosamala, kugwiritsa ntchito matanki amadzimadzi a nayitrogeni pamalo otentha kwambiri a -196 digiri Celsius ndikofunikira kwambiri.
Matanki a nayitrogeni amadzimadziKawirikawiri amagawidwa m'magulu awiri: matanki osungiramo nayitrogeni yamadzimadzi ndi matanki onyamula nayitrogeni yamadzimadzi. Matanki osungiramo zinthu amagwiritsidwa ntchito makamaka posungira nayitrogeni yamadzimadzi mkati, yokhala ndi mphamvu zambiri komanso kuchuluka komwe sikuli koyenera kunyamula mtunda wautali m'malo ogwirira ntchito.
Mosiyana ndi zimenezi, matanki oyendera nayitrogeni yamadzimadzi ndi opepuka kwambiri ndipo amapangidwira kukwaniritsa zofunikira zoyendera. Kuti atsimikizire kuti ndi oyenera kunyamula, matankiwa amapangidwa mwapadera kuti asagwedezeke. Kupatula kusungidwa kosasinthika, amatha kugwiritsidwa ntchito ponyamula pamene ali odzazidwa ndi nayitrogeni yamadzimadzi, koma kusamala kuyenera kuchitidwa kuti kupewe kugundana kwakukulu ndi kugwedezeka.
Mwachitsanzo, Haier Biomedical's Liquid Nitrogen Biobanking Series imatha kunyamula zitsanzo zamoyo m'malo otentha kwambiri. Kapangidwe kake kamaletsa kutulutsa kwa nayitrogeni wamadzimadzi panthawi yonyamula.
Muzochitika zomwe ogwira ntchito amafunikira mayendedwe apandege a nthawi yochepa, Biobanking Series ndi yofunika kwambiri. Mndandanda uwu uli ndi kapangidwe kolimba ka aluminiyamu yokhala ndi ma voliyumu asanu oti musankhe, chitsimikizo cha zaka zitatu cha vacuum, kutsimikizira chitetezo cha zitsanzo kwa nthawi yayitali. Matanki amatha kusunga ma botolo a cryogenic kapena machubu oziziritsa a 2ml, okhala ndi cholekanitsa chapadera cha maukonde osapanga dzimbiri kuti asungidwe komanso thupi lothira nayitrogeni wamadzimadzi. Zivindikiro zomwe zingatsekedwe zimawonjezera chitetezo chowonjezera kusungirako zitsanzo.
Ngakhale kapangidwe ka matanki a nayitrogeni wamadzimadzi kamapangitsa kuti zinthu ziyende bwino, njira zingapo zotetezera ziyenera kutsatiridwa panthawi yonse yoyendera. Choyamba, ndikofunikira kuonetsetsa kuti ma switch onse a ma valve pa thanki ya nayitrogeni wamadzimadzi ali mu mkhalidwe womwewo monga momwe amasungira. Kuphatikiza apo, thankiyo iyenera kuyikidwa mkati mwa chimango chamatabwa chokhala ndi tsinde loyenera, ndipo ngati kuli kofunikira, imamangiriridwe ku galimoto yonyamulira pogwiritsa ntchito zingwe kuti isasunthike panthawi yoyendera.
Kuphatikiza apo, kugwiritsa ntchito zodzaza pakati pa matanki ndikofunikira kwambiri kuti tipewe kukangana ndi kugundana panthawi yonyamula, motero kupewa ngozi. Mukakweza ndi kutsitsa matanki amadzimadzi a nayitrogeni, muyenera kusamala kuti asagundane. Kuzikokera pansi sikuloledwa, chifukwa kungachepetse moyo wa matanki amadzimadzi a nayitrogeni.
