Hauv kev ua liaj ua teb ntawm biology thiab tshuaj, kev tiv thaiv ntawm cov qauv tshuaj lom neeg yog qhov tseem ceeb tshaj plaws.Sib nrug los ntawm "pw tsaug zog" hauv chav kuaj thiab tsev kho mob, cov qauv no feem ntau xav tau kev thauj mus los.Txhawm rau khaws cia lossis thauj cov qauv no muaj txiaj ntsig zoo, kev siv cov kua nitrogen tso tsheb hlau luam ntawm qhov kub qis qis ntawm -196 degrees Celsius yog qhov tseem ceeb.
Cov kua nitrogen tankFeem ntau muab faib ua ob hom: kua nitrogen cia tanks thiab kua nitrogen thauj tso tsheb hlau luam.Cov tso tsheb hlau luam feem ntau yog siv rau kev khaws cia ntawm cov kua nitrogen hauv tsev, nrog lub peev xwm loj dua thiab cov ntim uas tsis tsim nyog rau kev thauj mus los ntev hauv lub xeev ua haujlwm.
Nyob rau hauv sib piv, kua nitrogen thauj tso tsheb hlau luam yog hnyav dua thiab tsim kom tau raws li kev thauj mus los.Txhawm rau kom tsim nyog rau kev thauj mus los, cov tso tsheb hlau luam no tau tsim tshwj xeeb los tiv thaiv kev vibration.Dhau li ntawm kev cia khoom zoo li qub, lawv tuaj yeem siv rau kev thauj mus los thaum muaj cov kua nitrogen, tab sis yuav tsum tau ceev faj kom tsis txhob muaj kev sib tsoo hnyav thiab kev co.
Piv txwv li, Haier Biomedical's Liquid Nitrogen Biobanking Series muaj peev xwm thauj cov tshuaj lom neeg nyob rau hauv qhov chaw sib sib zog nqus ultra-tsawg kub.Nws cov qauv tsim tau zoo tiv thaiv kev tso tawm cov kua nitrogen thaum lub sijhawm thauj mus los.
Hauv cov xwm txheej uas cov neeg ua haujlwm xav tau kev thauj mus los hauv huab cua luv luv, Biobanking Series ua pov thawj tsis muaj nuj nqis.Cov koob no nta cov qauv txhuas muaj zog nrog tsib lub ntim tshwj xeeb xaiv los ntawm, lub tshuab nqus tsev 3 xyoos, ua kom muaj kev nyab xeeb ntev ntawm cov qauv.Cov tso tsheb hlau luam tuaj yeem khaws cov vials cryogenic lossis 2ml tus qauv khov raj, nruab nrog tshwj xeeb stainless-steel mesh cais rau qhov chaw cia thiab lub cev ua kua nitrogen adsorption.Yeem lockable hau ntxiv ib txheej ntxiv ntawm kev ruaj ntseg rau cov qauv cia.
Thaum tsim cov kua nitrogen tso tsheb hlau luam ua kom yooj yim rau kev thauj mus los, ntau qhov kev tiv thaiv kev nyab xeeb yuav tsum tau ua raws li tag nrho cov txheej txheem thauj.Ua ntej, nws yog ib qho tseem ceeb los xyuas kom meej tias tag nrho cov valve hloov ntawm cov kua nitrogen tank nyob rau hauv tib lub xeev raws li thaum lub sij hawm cia.Tsis tas li ntawd, lub tank yuav tsum tau muab tso rau hauv ib lub thav duab ntoo nrog lub cushioning kom zoo, thiab yog tias tsim nyog, muab kev ruaj ntseg rau lub tsheb thauj khoom siv hlua los tiv thaiv kev txav mus los thaum lub sijhawm thauj mus los.
Tsis tas li ntawd, kev siv fillers ntawm cov tso tsheb hlau luam yog qhov tseem ceeb los tiv thaiv kev sib tw thiab kev cuam tshuam thaum thauj, yog li tsis txhob muaj xwm txheej.Thaum thauj thiab tshem tawm cov kua nitrogen tso tsheb hlau luam, yuav tsum tau saib xyuas kom tsis txhob muaj kev sib tsoo.Drag lawv rau hauv av yog poob siab heev, vim nws yuav txo tau lub neej ntawm cov kua nitrogen tso tsheb hlau luam.
