Cov txheej txheem khov-ziab

1. Ua ntej lyophilization, faib tawm cov khoom lag luam kom lyophilized rau hauv cov thawv kom tsim nyog;

2. Txias lub thawv lyophilized rau hauv lub thawv khoob, thiab tom qab ntawd muab cov khoom tso rau hauv lub thawv lyophilized rau kev kho mob ua ntej; lossis muab cov khoom tso rau txheej sab hauv ntawm lub thawv lyophilized rau kev tso kom khov ua ntej rau tib lub sijhawm;

3. Raws li cov cua txias ua kom sai ntawm lub tub yees txias, ua kom tus kwj dej ua haujlwm ua ntej, thiab tom qab ntawd ua lub tshuab nqus tsev. Lub rws yuav tsum txog rau qhov kub txog tsawg kawg -40 ° C thaum lub tshuab nqus tsev;

4. Tom qab kawm tiav qib nqus nce mus txog qee yam muaj nuj nqis (feem ntau nqus tsev kawm ntawv tsis pub dhau 13Pa ~ 26Pa), lossis qee cov txheej txheem lyophilization xav tau cov qib nqus yuav tsum tau txuas mus ntxiv rau ntau dua 1 ~ 2h; cov khoom hauv lub thawv yuav ua Tau Tshav Kub. Feem ntau, kev ua kom sov yog ua tiav nyob hauv ob kauj ruam. Thawj kauj ruam ntawm kev ua kom sov tsis ua rau qhov kub thiab txias ntawm cov khoom ua dhau ntawm qhov ntsuas kub ntawm cov ntsiab lus eutectic melting lossis eutectic. Tom qab cov dej noo hauv cov khoom yog yeej qhuav, theem thib ob ntawm kev ua kom sov. Lub sijhawm no, cov khoom tuaj yeem muab tau sai. Nce siab tshaj plaws qhov tso cai kub. Tom qab qhov siab tshaj qhov tso cai tau tswj cia rau ntau dua 2h, khov-qhuav yuav ua kom tas;

5. Tom qab khov-kom qhuav tiav, sau cov cua kom qhuav thiab huv rau hauv lub thawv kom qhuav, thiab tom qab ntawd cov nres nres kom sai li sai tau kom tsis txhob rov thim qhov dej noo hauv huab cua.
