M'zaka zaposachedwapa, mabanki a biobank akhala akuchita gawo lofunika kwambiri pa kafukufuku wa sayansi. Zipangizo zosungiramo zinthu zotsika mtengo kwambiri zimatha kuonetsetsa kuti zitsanzozo ndi zotetezeka komanso zimathandiza ofufuza kuchita bwino kafukufuku wa sayansi popereka malo osungiramo zinthu zamoyo mwaukadaulo komanso motetezeka.
Matanki a nayitrogeni amadzimadzi akhala akugwiritsidwa ntchito kusungira zitsanzo kwa nthawi yayitali. Amasunga zitsanzo pa kutentha kochepa kwa -196 ℃ komwe kumapangidwa potengera mfundo ya vacuum insulation pambuyo poti zitsanzozo zazizira kale. Pali njira ziwiri zosungira zitsanzo za matanki a nayitrogeni amadzi ...
1. Kugwiritsa ntchito
Matanki a nayitrogeni a gawo lamadzi amagwiritsidwa ntchito makamaka m'ma laboratories, ulimi wa ziweto, ndi gawo lokonza zinthu.
Matanki a nayitrogeni amadzimadzi a nthunzi amagwiritsidwa ntchito makamaka m'mabanki a biobanks, mankhwala, ndi m'munda wa chisamaliro chaumoyo.
2. Mkhalidwe Wosungirako
Mu gawo la nthunzi, zitsanzo zimasungidwa mwa kuzizira nayitrogeni yamadzimadzi. Kutentha kosungirako kumayambira pamwamba mpaka pansi pamalo osungira zitsanzo. Poyerekeza, mu gawo lamadzimadzi, zitsanzo zimasungidwa mwachindunji mu nayitrogeni yamadzimadzi pa -196 °C. Zitsanzozo ziyenera kumizidwa kwathunthu mu nayitrogeni yamadzimadzi.

Kuwonjezera pa kusiyana kumeneku, kuchuluka kwa nayitrogeni yamadzimadzi m'magawo awiriwa kumasiyananso. Kawirikawiri, kuchuluka kwa nayitrogeni yamadzimadzi kumatengera kukula kwa thanki ya nayitrogeni yamadzimadzi, kuchuluka kwa ogwiritsa ntchito omwe amatsegula chivindikiro, njira yopangira, komanso kutentha ndi chinyezi. Koma mwachibadwa, ukadaulo wapamwamba wa vacuum ndi insulation womwe umagwiritsidwa ntchito popanga matanki a nayitrogeni yamadzimadzi ndi chinsinsi chowonetsetsa kuti nayitrogeni yamadzimadzi imagwiritsidwa ntchito pang'ono.
Kusiyana kwakukulu pakati pa ziwirizi kuli m'njira yomwe zitsanzo zimasungidwira. Zikasungidwa mu gawo la nthunzi, zitsanzo sizimakhudzana mwachindunji ndi nayitrogeni yamadzimadzi, zomwe zimaletsa mabakiteriya kuipitsa zitsanzozo. Komabe, kutentha kwa malo osungira sikungafikire -196°C. Mu gawo lamadzimadzi, ngakhale zitsanzo zitha kusungidwa pafupifupi -196°C, chubu chosungira madzi chimakhala chosakhazikika. Ngati chubu chosungira madzi sichinatsekedwe bwino, nayitrogeni yamadzimadzi idzalowa mu chubu. Chubu choyesera chikachotsedwa, kusinthasintha kwa nayitrogeni yamadzimadzi kudzatsogolera ku kupanikizika kosalinganika mkati ndi kunja kwa chubu choyesera ndipo chubucho chidzaphulika chifukwa chake. Chifukwa chake, umphumphu wa chitsanzocho udzatayika. Izi zikusonyeza kuti pali zabwino ndi zoyipa za njira iliyonse.
Kodi Mungatani Kuti Mukhale ndi Kulinganiza Pakati pa Awiriwa?
Mndandanda wa biobank wa Haier Biomedical Liquid Nitrogen Storage System wapangidwa kuti usungidwe m'madzi ndi m'nyengo yozizira.
Ikuphatikiza ubwino wa kusungirako nthunzi ndi madzi, yopangidwa ndi ukadaulo wapamwamba wa vacuum ndi insulation kuti zitsimikizire chitetezo cha kusungirako ndi kutentha kofanana pamene imachepetsa kugwiritsa ntchito nayitrogeni wamadzi. Kusiyana kwa kutentha kwa malo onse osungirako sikupitirira 10°C. Ngakhale mu nthunzi, kutentha kwa kusungirako pafupi ndi pamwamba pa shelufu kumakhala kotsika kufika -190°C.
Mndandanda wa Biobank Wosungira Zinthu Zambiri
Kuphatikiza apo, masensa olondola kwambiri kutentha ndi madzi amagwiritsidwa ntchito kuti atsimikizire kulondola. Deta ndi zitsanzo zonse zimatetezedwa ndi njira yotetezeka yowongolera kulowa. Masensa awa amawunika kutentha ndi madzi mu thanki ya nayitrogeni yamadzi nthawi yeniyeni, motero madzi omwe ali mu thanki amatha kubwezeretsedwanso okha kuti apange malo otetezeka osungira zitsanzo.
