Yuav Siv Liyophilizer li cas?

Lyophilization, tseem hu ua freeze-drying, yog cov txheej txheem tseem ceeb hauv ntau yam kev tshawb fawb thiab kev lag luam. Txawm hais tias koj tab tom khaws cia cov qauv tshuaj lom neeg, tsim cov khoom siv tshuaj, lossis npaj zaub mov rau kev khaws cia ntev, kev nkag siab txog kev siv lyophilizer yog qhov tseem ceeb. Kab lus no tsom rau cov lyophilizers me me, uas yog qhov zoo tshaj plaws rau cov chaw kuaj mob lossis kev ua haujlwm me me.

 

Peb yuav qhia koj txog kev siv ame me lyophilizer, los ntawm cov qauv kev npaj mus rau qhov kawg qhuav khoom. Los ntawm kev paub txog cov txheej txheem no, koj tuaj yeem khaws cov ntaub ntawv thaum tuav lawv cov qauv qub thiab cov khoom. Txawm hais tias koj yog ib tus kws tshawb fawb, kws kho tshuaj, lossis tsuas yog xav paub txog kev tshawb fawb tom qab khov-qhuav, phau ntawv qhia dav dav no yuav muab kev paub thiab kev ntseeg siab rau kev ua haujlwm me me lyophilizer zoo.

 

 

Ua ntej dhia mus rau hauv qhov tshwj xeeb ntawm kev siv cov lyophilizer me me, nws yog ib qho tseem ceeb kom nkag siab txog cov ntsiab lus tseem ceeb tom qab cov txheej txheem khov-qhuav. Lyophilization yog ib txoj hauv kev khaws cov ntaub ntawv los ntawm kev tshem tawm cov dej los ntawm sublimation. Cov txheej txheem no suav nrog peb theem tseem ceeb: khov, ua kom qhuav, thiab ua kom qhuav.

 

Nyob rau hauv lub freezing theem, tus qauv yog txias rau hauv qab nws triple point, ua rau cov dej nyob rau hauv nws los ua ice crystals. Cov kauj ruam no yog qhov tseem ceeb vim nws txiav txim siab qhov kawg qauv ntawm cov khoom qhuav. Thawj theem ziab, tseem hu ua sublimation, suav nrog tshem cov dej khov ncaj qha los ntawm cov khoom mus rau lub xeev roj hauv lub tshuab nqus tsev. Thaum kawg, kev ziab khaub ncaws theem nrab tshem tawm cov dej tsis khov uas tsis muaj molecules los ntawm desorption.

 

Cov lyophilizers me me yog tsim los ua cov txheej txheem no ntawm qhov me me, ua rau lawv zoo tagnrho rau kev siv hauv chav kuaj lossis cov khoom me me. Cov tshuab compact no feem ntau muaj xws li lub freeze-drying chamber, ib tug txias ntxiab (los yog condenser), lub tshuab nqus tsev twj, thiab ib tug tswj system. Kev nkag siab tias cov khoom no ua haujlwm ua ke li cas yog qhov tseem ceeb rau kev ua tiav cov lyophilizer me me.

Qhov zoo ntawm kev siv ame me lyophilizer suav nrog:

● Kev khaws cia cov ntaub ntawv kub-sensitive

● Kev saib xyuas ntawm cov qauv qub thiab cov khoom ntawm cov qauv

● Lub neej ntev ntawm cov khoom qhuav

● Ib qho yooj yim reconstitution ntawm cov khoom qhuav

● Txo kev pheej hmoo ntawm kev kis kab mob thaum khaws cia

Tam sim no peb tau npog cov hauv paus, cia peb mus rau cov kauj ruam ntawm kev siv cov lyophilizer me me.

 

 

Kev npaj kom zoo yog qhov tseem ceeb rau kev ua tiav lyophilization. Txoj kev uas koj npaj koj cov qauv tuaj yeem cuam tshuam qhov kev ua tau zoo ntawm cov txheej txheem khov-qhuav thiab qhov zoo ntawm cov khoom kawg. Nov yog cov lus qhia ua ntu zus los npaj koj cov qauv siv rau hauv lyophilizer me me:

● Xaiv cov ntim khoom tsim nyog:Xaiv cov thawv uas sib haum nrog koj cov lyophilizer me me. Cov no yuav tsum muaj peev xwm tiv taus qhov kub thiab txias thiab lub tshuab nqus tsev. Cov kev xaiv muaj xws li iav vials, yas raj, los yog tsim tshwj xeeb lyophilization tais.

● Txiav txim siab ntim cov qauv:Qhov ntim ntawm koj tus qauv yog qhov tseem ceeb. Feem ntau, koj yuav tsum tau ntim cov ntim tsis pub ntau tshaj 1/3 txog 1/2 tag nrho kom tso cai rau kev nthuav dav thaum lub sijhawm khov thiab tiv thaiv kev dhau thaum lub sijhawm ziab.

● Ua ntej khov koj cov qauv:Ua ntej muab cov qauv tso rau hauv lyophilizer, ua ntej khov lawv ntawm qhov kub thiab txias hauv qab lawv qhov chaw eutectic. Cov kauj ruam no tuaj yeem ua tiav hauv lub freezer tsis tu ncua lossis siv lub freeze-dryer lub txee-freezing muaj peev xwm yog tias muaj.

● Xav txog kev siv cov khoom ntxiv:Nyob ntawm koj hom qauv, tej zaum koj yuav xav tau ntxiv stabilizers lossis bulking agents. Cov no tuaj yeem pab tswj cov qauv ntawm cov khoom thaum lub sijhawm khov-qhuav thiab txhim kho nws cov khoom siv rov ua dua tshiab.

● Xyuas kom khov tsis khov:Sim ua kom tiav tus nqi khov tsis sib xws thoob plaws txhua qhov qauv. Qhov no pab tsim cov qauv pore zoo ib yam hauv cov khoom qhuav, uas yog qhov tseem ceeb rau kev ua kom zoo sublimation thiab rov ua kom dej.

● Sau koj cov qauv:Kev sau ntawv kom raug yog qhov tseem ceeb, tshwj xeeb tshaj yog thaum ua haujlwm nrog ntau yam qauv. Siv cov ntawv uas tuaj yeem tiv taus qhov kub thiab txias thiab lub tshuab nqus tsev.

Nco ntsoov, tus yuam sij rau kev ua tiav lyophilization yog nyob rau hauv kev npaj ua tib zoo npaj. Siv sijhawm los npaj koj cov qauv kom zoo yuav ua rau muaj txiaj ntsig zoo dua thiab siv tau zoo dua ntawm kojme me lyophilizer.

 

Tam sim no uas koj cov qauv tau npaj, nws yog lub sijhawm los khiav koj cov lyophilizer me me. Txawm hais tias cov lus qhia tshwj xeeb yuav txawv nyob ntawm tus qauv, ntawm no yog cov lus qhia ib kauj ruam los ntawm kauj ruam los pab koj los ntawm cov txheej txheem:

● Fais fab rau thiab ua ntej txias:Qhib koj lub lyophilizer me me thiab tso cai rau lub condenser txias rau nws qhov kev khiav hauj lwm kub (feem ntau ntawm -40 degree rau -80 degree ). Qhov no yuav siv sij hawm 30 feeb mus rau ib teev.

● Thauj koj cov qauv:Thaum lub condenser txias, ua tib zoo thauj koj cov qauv ua ntej khov rau hauv lub tshuab ziab khaub ncaws. Xyuas kom lawv muab tso ruaj ntseg thiab sib npaug.

● Kaw thiab kaw lub chamber:Ua tib zoo kaw thiab kaw lub tshuab ziab khaub ncaws kom tswj tau lub tshuab nqus tsev thaum ua haujlwm.

● Pib lub tshuab nqus tsev twj:Pib lub tshuab nqus tsev twj kom pib tshem tawm cov pa tawm ntawm lub chamber. Lub siab yuav tsum poob sai.

● Saib xyuas cov txheej txheem:Khaws qhov muag ntawm qhov kub thiab txias nyeem ntawv. Lub siab yuav tsum ruaj khov nyob rau theem qis (feem ntau hauv qab 0.1 mbar), qhia tias sublimation tau pib.

● Kev ziab thawj zaug:Qhov no yog lub sijhawm ntev tshaj ntawm cov txheej txheem. Khaws lub tshuab nqus tsev thiab saib xyuas qhov kub thiab txias. Lub sijhawm tuaj yeem sib txawv ntawm cov xuab moos mus rau hnub nyob ntawm koj cov qauv ntim thiab muaj pes tsawg leeg.

● Secondary drying:Thaum cov dej khov tau sublimed, nce lub txee kub maj mam tshem tawm cov dej uas tseem tshuav. Cov theem no feem ntau luv dua li thawj zaug ziab.

● Xaus lub voj voog:Thaum cov txheej txheem ua tiav, maj mam tso lub tshuab nqus tsev thiab tso cai rau lub chamber rov qab rau atmospheric siab.

● Tshem tawm cov qauv:Ua tib zoo tshem koj cov qauv lyophilized los ntawm lub chamber. Lawv yuav tsum qhuav thiab muaj cov qauv ntxeem tau.

● Ntxuav thiab tu:Tom qab siv, ntxuav koj tus kheejme me lyophilizerraws li cov neeg tsim khoom cov lus qhia. Kev saib xyuas tsis tu ncua yog qhov tseem ceeb rau kev ua haujlwm zoo.
