Cov cuab ntxiab txias yog ib qho khoom siv rau kev ntes noo noo hauv cov txheej txheem khov-kom qhuav. Theoretically, qhov qis dua qhov ntsuas kub ntawm cov dej txias, qhov muaj zog ntawm cov dej txias, tab sis qhov siab dua cov nqi txias, lub tshuab siab dua thiab cov nqi khiav. Lub tsheb txias txias ntawm cov kev sim ua kom khov tshuab hluav taws xob tshuab hluav taws xob noo noo feem ntau muaj ob peb qib ntawm {1} -80 degree.
Khov-kom qhuav ntawm -55 degree yog tsim nyog rau qee cov khoom khov-qhuav. Khov-kom qhuav ntawm -80 degree yog haum rau Lyophilization ntawm qee cov khoom tshwj xeeb.
Cov nyhuv txias ntawm cov dej-tsheb muaj peev xwm qhia tau tias qhov ntsuas kub ntawm {}}}} degrape, thiab cov dej-ntaiv tau zoo dua. Tus txias trap ntsuas kub yog qis dua -55 degree, thiab dej cuab lub peev xwm muaj peev xwm hloov kho txias.
Yog li ntawd, thaum tsis muaj kev xav tau tshwj xeeb, kev xaiv ntawm txias trap qhov kub {{0} degree c yog qhov kev xaiv zoo tshaj plaws.
