M'zaka zaposachedwa, ma biobanks akhala akuchita mbali yofunika kwambiri pakufufuza kwasayansi.Zida zosungirako zotsika kwambiri zimatha kutsimikizira chitetezo ndi zochitika za zitsanzo ndikuthandizira ochita kafukufuku kuti azichita bwino kafukufuku wa sayansi osiyanasiyana popereka malo osungiramo akatswiri komanso otetezeka a zitsanzo zamoyo.
Matanki a nayitrogeni amadzimadzi akhala akugwiritsidwa ntchito posungira zitsanzo kwa nthawi yayitali.Amasunga zitsanzo pa kutentha kochepa kwa -196 ℃ opangidwa pamaziko a mfundo ya vacuum insulation pambuyo poti zitsanzozo zitazizidwa kale.Pali njira ziwiri zosungiramo zitsanzo za matanki a nayitrogeni amadzimadzi: kusungirako gawo lamadzimadzi ndi kusungirako gawo la nthunzi.Kodi pali kusiyana kotani pakati pa ziwirizi?
1. Kugwiritsa ntchito
Matanki a nayitrogeni a gawo lamadzimadzi amagwiritsidwa ntchito kwambiri m'malo opangira ma laboratories, kuweta ziweto, ndi gawo lokonza.
Matanki a nayitrogeni a Vapor phase liquid amagwiritsidwa ntchito makamaka m'mabanki a bio, mankhwala, ndi malo azaumoyo.
2. Mkhalidwe Wosungirako
Mu gawo la nthunzi, zitsanzo zimasungidwa ndi evaporating ndi kuziziritsa madzi nayitrogeni.Kutentha kosungirako kumachokera pamwamba mpaka pansi kumalo osungirako zitsanzo.Poyerekeza, mu gawo lamadzimadzi, zitsanzo zimasungidwa mwachindunji mu nayitrogeni wamadzimadzi pa -196 ° C.Zitsanzozo ziyenera kumizidwa kwathunthu mu nayitrogeni wamadzimadzi.
Haier Biomedical Liquid Nitrogen Container-Smart Series
Kuphatikiza pa kusiyana kumeneku, mitengo ya nayitrogeni yamadzimadzi yamadzimadzi imakhalanso yosiyana.Nthawi zambiri, kuchuluka kwa evaporation yamadzimadzi a nayitrogeni kumatengera kukula kwa thanki ya nayitrogeni yamadzimadzi, kuchuluka kwa ogwiritsa ntchito kutsegula chivindikiro, kupanga, komanso kutentha ndi chinyezi.Koma mwachibadwa, matekinoloje apamwamba a vacuum ndi insulation omwe amagwiritsidwa ntchito popanga matanki amadzimadzi a nayitrogeni ndiye chinsinsi chowonetsetsa kuti nayitrogeni wamadzimadzi amamwa pang'ono.
Kusiyana kwakukulu pakati pa ziwirizi kwagona momwe zitsanzo zimasungidwira.Zosungidwa mu gawo la nthunzi, zitsanzo sizimalumikizana mwachindunji ndi nayitrogeni wamadzimadzi, kuletsa mabakiteriya kuti asayipitse zitsanzo.Komabe, kutentha kosungirako sikungathe kufika -196 ° C.Mu gawo lamadzimadzi, ngakhale zitsanzo zitha kusungidwa pafupifupi -196 ° C, chubu cha cryopreservation sichikhazikika.Ngati chubu cha cryopreservation sichimasindikizidwa bwino, nayitrogeni wamadzimadzi amalowa mu chubu.Pamene chubu choyesera chikutulutsidwa, kusungunuka kwa nayitrogeni wamadzimadzi kumayambitsa kupanikizika kosalinganiza mkati ndi kunja kwa chubu choyesera ndipo chubu chidzaphulika chifukwa chake.Choncho, kukhulupirika kwa chitsanzo kudzatayika.Izi zikusonyeza kuti pali ubwino ndi kuipa kwa njira iliyonse.
Kodi Mungatani Kuti Mugwirizane Pakati pa Awiriwa?
Mndandanda wa biobank wa Haier Biomedical Liquid Nitrogen Storage System wapangidwira kusungirako madzi ndi nthunzi.
Zimagwirizanitsa ubwino wa kusungirako gawo la nthunzi ndi kusungirako gawo lamadzimadzi, lopangidwa ndi makina apamwamba a vacuum ndi kutchinjiriza kuonetsetsa chitetezo chosungirako ndi kutentha mofanana ndikuchepetsa kugwiritsa ntchito nayitrogeni wamadzimadzi.Kusiyana kwa kutentha kwa malo onse osungira sikudutsa 10 ° C.Ngakhale mu gawo la nthunzi, kutentha kosungirako pafupi ndi pamwamba pa shelefu kumatsika mpaka -190°C.
Biobank Series Yosungirako Kukulu Kwambiri
Kuphatikiza apo, kutentha kwapamwamba kwambiri komanso masensa amadzimadzi amagwiritsidwa ntchito kuti atsimikizire kulondola.Deta ndi zitsanzo zonse zimatetezedwa ndi njira yolowera yotetezeka.Masensa awa amawunika kutentha ndi kuchuluka kwamadzi mu tanki yamadzimadzi ya nayitrogeni mu nthawi yeniyeni, chifukwa chake madzi omwe ali mu thanki amatha kuwonjezeredwa kuti apange malo otetezeka kwambiri osungiramo zitsanzo.
