Pazinthu za biology ndi zamankhwala, chitetezo cha zitsanzo zamoyo ndizofunikira kwambiri.Kupatula kukhala "m'tulo" m'ma laboratories ndi zipatala, zitsanzozi nthawi zambiri zimafunikira mayendedwe.Kuti musunge kapena kunyamula zitsanzo zamtengo wapatali zachilengedwezi, kugwiritsa ntchito akasinja amadzimadzi a nayitrogeni pa kutentha kwambiri kotsika kwambiri -196 digiri Celsius ndikofunikira.
Matanki a nayitrogeni amadzimadziNthawi zambiri amagawidwa m'mitundu iwiri: matanki osungiramo nayitrogeni wamadzimadzi ndi akasinja onyamula nayitrogeni amadzimadzi.Matanki osungira amagwiritsidwa ntchito posungirako mwakachetechete wa nayitrogeni wamadzi m'nyumba, okhala ndi mphamvu zazikulu komanso ma voliyumu omwe sali oyenera kuyenda mtunda wautali m'malo ogwirira ntchito.
Mosiyana ndi izi, akasinja onyamula nayitrogeni wamadzimadzi ndi opepuka kwambiri ndipo amapangidwa kuti akwaniritse zofunikira zamayendedwe.Kuti awonetsetse kuti ali oyenera mayendedwe, akasinja awa amapangidwa mwaukadaulo woletsa kugwedezeka.Kupatula kusungidwa kosasunthika, atha kugwiritsidwa ntchito ngati mayendedwe atadzazidwa ndi nayitrogeni wamadzimadzi, koma kusamala kuyenera kuchitidwa kupeŵa kugunda kwakukulu ndi kugwedezeka.
Mwachitsanzo, Haier Biomedical's Liquid Nitrogen Biobanking Series imatha kunyamula zitsanzo zachilengedwe m'malo otentha kwambiri.Mapangidwe ake amalepheretsa kutulutsa nayitrogeni wamadzi panthawi yoyendetsa.
M'malo omwe ogwira ntchito amafunikira zoyendera ndege kwakanthawi kochepa, Biobanking Series imakhala yofunikira kwambiri.Mndandandawu uli ndi mawonekedwe olimba a aluminiyumu okhala ndi ma voliyumu asanu oti musankhe, chitsimikizo cha vacuum chazaka 3, kuwonetsetsa kuti zitsanzo zili zotetezeka.Matanki amatha kusunga Mbale za cryogenic kapena machubu oziziritsa a 2ml, okhala ndi cholekanitsa chapadera chachitsulo chosapanga dzimbiri chosungiramo malo osungira komanso thupi lamadzi la nitrogen adsorption.Zivundikiro zotsekeka zosafunikira zimawonjezera chitetezo chowonjezera pakusungirako zitsanzo.
Ngakhale mapangidwe a matanki a nayitrogeni amadzimadzi amathandizira mayendedwe, njira zingapo zodzitetezera ziyenera kutsatiridwa munthawi yonseyi.Choyamba, ndikofunikira kuwonetsetsa kuti mavavu onse pa thanki ya nayitrogeni yamadzimadzi ali mumkhalidwe wofanana ndi nthawi yosungira.Kuonjezera apo, thankiyo iyenera kuikidwa mkati mwa matabwa omwe ali ndi mapiko oyenera, ndipo ngati kuli koyenera, otetezedwa ku galimoto yonyamula katundu pogwiritsa ntchito zingwe kuti ateteze kuyenda kulikonse panthawi ya mayendedwe.
Kuphatikiza apo, kugwiritsa ntchito zodzaza pakati pa akasinja ndikofunikira kuti mupewe kuthamanga komanso zovuta pamayendedwe, potero kupewa ngozi.Mukatsitsa ndikutsitsa akasinja a nayitrogeni amadzimadzi, chisamaliro chiyenera kuperekedwa kuti zisagundane.Kuwakokera pansi kumalepheretsedwa kwambiri, chifukwa kumachepetsa moyo wa akasinja amadzimadzi nayitrogeni.
