Hauv thaj chaw ntawm biopharmaceuticals thiab kev tshawb fawb tshawb fawb, kev tshem tawm cov kuab tshuaj thiab cov khoom siv concentration yog cov kauj ruam tseem ceeb hauv kev sim thiab kev tsim khoom. Cov txheej txheem ib txwm muaj xws li evaporation thiab centrifugation feem ntau raug kev txom nyem los ntawm kev ua haujlwm tsis zoo, poob ntawm cov khoom xyaw nquag, thiab tshem tawm cov kuab tshuaj tsis tiav. Laboratory freeze dryers, nrog rau lawv qhov tshwj xeeb zoo ntawm qhov kub thiab txias tsis tshua muaj siab, tau tshwm sim los ua cov cuab yeej siv tau zoo rau cov txheej txheem no. Ntawm lawv,"OB" khov tshuab ziab khaub ncawsyog nyob rau hauv pem hauv ntej ntawm advancing no technology.
Kev Tshawb Fawb Tom Qab Txias-Drying: Tsawg-Temperature Dehydration
A Laboratory freeze dryerua tiav cov kuab tshuaj tshem tawm thiab cov khoom siv concentration los ntawm peb theem tseem ceeb:
Pre-freezing theem:Cov khoom uas muaj cov kuab tshuaj yog khov sai heev ntawm qhov kub ntawm -40 ° C txog -80 ° C, tsim cov dej khov khov khov.
Kev ziab qhuav (Sublimation):Nyob rau hauv ib puag ncig lub tshuab nqus tsev (feem ntau qis dua 10Pa), cov dej khov nab kuab ncaj qha sublimate rau hauv dej vapor, tshem tawm tshaj 90% ntawm cov kuab tshuaj.
Secondary Drying (Desorption):Qhov kub nce siab (20-40 ° C) ua kom yooj yim rau kev ua tiav ntawm cov dej khi, ua rau cov dej noo kawg ntawm 1% -5%.
Cov txheej txheem no tshem tawm qhov kub thiab txias ua rau cov khoom kub-rhiab heev, khaws cia cov qauv molecular ntawm cov proteins, enzymes, thiab vitamins. Tsis tas li ntawd, nws tsim cov qauv ntxeem tau yooj yim uas yooj yim rehydration los yog daim ntawv thov ncaj qha.
Cov txiaj ntsig tseem ceeb ntawm Laboratory Freeze Dryers
Piv nrog rau cov cuab yeej siv hauv kev lag luam, chav kuaj khov tshuab ziab khaub ncaws muaj kev tswj xyuas zoo tshaj plaws thiab cov txiaj ntsig ua haujlwm me me:
Precise Temperature Control:Tus qauv "OB" khov tshuab ziab khaub ncawsZLJ-12Piv txwv li, siv cov tshuab cua compressor cua txias tuaj, ncav cuag qhov ntsuas kub tsawg li -80°C kom ua kom khov sai.
Intelligent Vacuum Management:High-precision sensors tsis tu ncua saib lub tshuab nqus tsev theem (≤5Pa), nrog cov txheej txheem tiv thaiv built-in los tiv thaiv cov kuab tshuaj.
Gradient Cua sov rau Concentration:Nruab nrog lub programmable txee cua sov (xws li "OB" lub tshuab ziab khaub ncaws PLD tswj tshuab), cov tshuab no tso cai rau qhov kub thiab txias nkhaus rau cov khoom sib txawv, optimizing concentration.
Piv txwv li, hauv kev sim tshuaj lom neeg nrog rau cov tshuaj tiv thaiv kab mob kom qhuav, cov txheej txheem evaporation ib txwm ua rau cov protein sib sau ua ke thiab deactivation. Hauv qhov sib piv, khov-qhuav ntawm qhov kub qis tau khaws cia ntau dua 95% ntawm cov tshuaj tiv thaiv kev ua haujlwm, nrog rau cov hmoov ua kom ruaj khov rau lub sijhawm ntev.
Raws li lub tuam txhab tshwj xeeb hauv cov khoom siv hauv tsev khov-qhuav rau 17 xyoo, "OB" lub tshuab ziab khaub ncaws tau txhim kho cov kuab tshuaj tshem tawm los ntawm kev siv thev naus laus zis txuas ntxiv.
1. Cov Txheej Txheem Tag Nrho Cov Ntaub Ntawv Traceability System
Lub "OB" lub tshuab ziab khaub ncaws khov yog nruab nrog cov xim kov thiab cov ntaub ntawv khaws cia (muaj peev xwm khaws cia txog 100,000 cov ntaub ntawv). Nws muab lub sijhawm ntsuas kub-lub tshuab nqus tsev nkhaus, ua rau cov kws tshawb fawb los txiav txim siab qhov kawg ntawm cov kuab tshuaj sublimation, tiv thaiv kev ziab dhau los yog cov teeb meem hnyav ntxiv.
2. Ntau yam kev tiv thaiv kev nyab xeeb
Tsis siv neeg lub tshuab nqus tsev twj tso kua mis kaw yog tias qhov ntsuas kub siab tshaj -50 ° C los tiv thaiv kev puas tsuaj rov qab.
Lub suab nrov thiab lub teeb ceeb toom nrog kev tiv thaiv tsis siv neeg ua haujlwm thaum lub tshuab nqus tsev tsis ua haujlwm lossis qhov kub thiab txias hloov pauv.
Optional UPS fais fab mov tswj tswj kev ua haujlwm rau 20 feeb thaum lub zog hluav taws xob, ua kom muaj kev sim txuas ntxiv.
3. Modular Function Expansion
Nrog rau qhov kev xaiv tsis siv neeg rov ua kom cov pa roj txhaj tshuaj, inert gases xws li nitrogen tuaj yeem nkag mus rau hauv lub tshuab ziab khaub ncaws kom tiv thaiv oxidation cov tshuaj tiv thaiv thaum lub sij hawm concentration ntawm oxygen-sensitive kuab tshuaj (xws li, ethanol). Lub chamber, ua los ntawm cov hlau tsis huv tsis huv nrog cov txheej txheem coil-free ntxiab, tshem tawm cov kev pheej hmoo ntawm kev sib kis.
Laboratory freeze dryers tau hloov zuj zus los ntawm cov khoom siv lub cev qhuav dej yooj yim rau hauv cov txheej txheem tswj cov txheej txheem. Qhov "OB"ZLGJseries, los ntawm nws cov kev txawj ntse thiab modular tsim, tsis tsuas yog txhim kho cov kuab tshuaj tshem tawm efficiency tab sis kuj enables real-time xyuas thiab optimization ntawm cov concentration txheej txheem. Rau cov kws tshawb fawb uas ua qhov tseem ceeb ntawm qhov kev sim siab thiab cov txiaj ntsig ruaj khov, cov cuab yeej no tau dhau los ua "tus txheej txheem txheej txheem" uas tsis tseem ceeb hauv cov chaw sim.
