Qhov zoo ntawm kev khov-ziab :
Cov txheej txheem ziab sib txawv, xws li ziab, kub nyhiab, ziab, tshuaj tsuag qhuav thiab xau qhuav, thiab lwm yam, tab sis feem ntau cov ziab qhuav yog feem ntau tshaj 0 ℃ lossis siab dua. Cov khoom qhuav feem ntau muaj shrinking ntim, qhov teeb meem ntawm kev ntxhib los mos, feem ntau ntawm cov khoom nthe qis yuav poob, qee cov khoom kub-sensitive degeneration, inactivation, thiab tej co tshuaj muaj oxidized. Yog li ntawd, cov khoom qhuav muaj qhov sib txawv loj hauv kev coj ua piv rau ua ntej ziab. Txoj cai lij choj lyophilization yog li ua tiav hauv 0 ° C, xws li thaum cov khoom khov thiab tsuas tso cai rau nce mus rau kub dua 0 ° C xwb yog tias cov ntsiab lus ntawm qhov khoom qis dua qub tom qab, tab sis feem ntau nws tsis tshaj 40 ° C. Raws li lub tshuab nqus tsev, thaum cov dej ua paug ncaj qha tuaj, cov tshuaj no tseem nyob hauv khov dej khov nab kuab, ua ib lub voj voos, ntxeem tau, ntxeem tau uas muaj qhov ntim tom qab ziab. Ua ntej siv dua, cia li ntxiv dej rau kev txhaj tshuaj thiab yaj sai. Lub cav kom khov thiab txhuam kom ntu cov pa kev ua pa, lyophilization muaj qhov zoo li hauv qab no:
* Muaj ntau yam tshuaj kub hnyiab-tsis muaj kev sib tw los sis ua tsis tau.
* Thaum qhuav ntawm qis kub, qee yam ntawm cov khoom tsis taus ntawm cov khoom poob yog me me.
* Nyob hauv txoj kev khov thiab ziab , txoj kev loj hlob ntawm cov kab mob thiab lub luag hauj lwm ntawm cov enzymes tsis tuaj yeem nqa tawm, yog li los tuav lub cim qub.
* Txij li thaum nws qhuav nyob hauv khov lub xeev, qhov ntim yog yuav luag zoo li qub, tus qauv qub yeej tswj tau, thiab qhov hnyuv tsis tshwm sim.
* Raws li cov khoom hauv dej tom qab ua ntej tso rau hauv daim ntawv ntawm cov dej khov nab kuab, cov thawj cov ntsev hauv cov kua dej hauv cov dej yaj cov dej muaj sib npaug ntawm cov khoom. Sublimation, yaj hauv cov dej txhaws teeb meem nag lossis daus, kom tsis txhob muaj txoj kev ziab los ntawm sab hauv ya mus rau ntawm cov khoom siv los ntawm cov migration ntawm inorganic salts nyob rau saum npoo av los ntawm qhov phenomenon ntawm cov tawv hardening.
* Tom qab so qhuav cov khoom xoob, zoo li daim txhuam cev, ua tiav sai sai thiab tag nrho tom qab ntxiv dej, yuav luag tam sim ntawd rov qab qub kev coj noj coj ua.
Vim qhuav hauv lub tshuab nqus tsev, muaj cov pa tsawg heev, yog li tej cov tshuaj oxidizable yooj yim tiv thaiv.
* Kev ziab tuaj yeem tshem tawm 95% ~ 99% ntawm cov dej, yog li ntawd cov khoom yuav tau qhuav tom qab ntev-preservation tsis muaj deterioration.
* Vim yog cov khoom nyob hauv lub xeev khov, qhov kub thiab txias tsis txaus, yog li cov cua kub qhov kub tsis yog xav tau, siv qhov kub thiab txias los ua kom tau raws li txoj cai. Yog tias lub tub yees lub tub yees thiab lub ziab ziab cais sib cais, qhov ziab chamber yuav tsum tsis yog kev zais thiab yuav tsis muaj cua sov ntau, yog li siv cov thermal energy yog kev lag luam.
Yog tus tsis muaj lub tshuab zoo meej, lub tshuab nqus tsev kom qhuav tshuab, lub ntsiab tseem ceeb yog qhov siab. Vim tias yuav tsum tau muaj lub tshuab nqus tsev thiab tsis tshua muaj qhov kub thiab txias, lub tshuab nqus tsev vacuum - txuas nrog lub tshuab nqus tsev thiab lub cev cryogenic, ua rau muaj peev ntau dua thiab cov nqi khiav lag luam.
Hangzhou Sumer Instrument Co., Ltd yog cov kws tshaj lij ntawm cov qauv kev lag luam, peb cov khoom tseem ceeb yog cov kab tsim kev lag luam, qhov cub kom qhuav (autoclave (sterilizer), centrifuge, microscope, spectrophotometer, dej distiller, thiab hais txog, daim ntawv thov kev kho mob, peb muab txhua yam kev xav tau ntawm kev ntsuas thiab kev ntsuas rau tsev kho mob, cov tsev kawm ntawv tshawb fawb, cov tsev kawm ntawv thiab tsoom fwv cov koom haum.
