Manifold Freeze Dryers

Txheej txheem cej luam ntawm Manifold Freeze Dryers

Lub tshuab ziab khaub ncaws manifold feem ntau yog siv los ua cov khoom siv nkag rau hauv khov ziab.Cov kws tshawb nrhiav uas tab tom nrhiav rau cov khoom siv tshuaj nquag lossis ua haujlwm HPLC feem ntau siv lub tshuab ziab khaub ncaws manifold thaum lawv thawj kauj ruam hauv chav kuaj.Kev txiav txim siab los yuav lub tshuab ziab khaub ncaws no feem ntau yog raws li cov txheej txheem uas suav nrog, tab sis tsis txwv rau:

1. -Tus naj npawb ntawm cov neeg siv hauv chav kuaj feem ntau yog siab thiab cov khoom uas lawv ua yog me me

2. -Log cov qauv me me

3. Cov cuab yeej siv nyiaj me me

4. Cell banking hom chaw

5. Khaws cov khoom qhuav qhuav tsis yog siv rau kev lag luam nyob rau theem no

6. Kev tshawb fawb thaum ntxov heev

7. Cov khoom lag luam tseem ceeb tsawg yuav tsum tau ua

Txawm hais tias coob tus ntawm cov tshuab manifold tau yuav thiab tsim nyog rau kev ua haujlwm ntawm tes, nws yog ib qho tseem ceeb kom nkag siab tias kev siv lub tshuab ziab khaub ncaws manifold muaj cov kev txwv tseem ceeb hais txog cov txheej txheem khov kom qhuav.Thaum kawg tus neeg teb xov tooj tsis muaj kev tswj hwm cov txheej txheem khov kom qhuav, raws li lawv xav tau hauv cov tais kim dua thiab nyuaj lossis txee hom khov tshuab ziab khaub ncaws.Txawm li cas los xij, muaj cov kauj ruam uas tuaj yeem ua los tsim kom muaj kev vam meej ntau dua ntawm lub tshuab ziab khaub ncaws manifold thaum siv cov khoom siv.Kab lus no yuav piav qhia txog cov txheej txheem manifold yooj yim, lawv cov kev txwv thiab lub zog thiab yuav ua li cas txo qee qhov teeb meem uas yuav tshwm sim thaum lub sij hawm khov ziab.

Nkag siab txog qhov chaw ntawm Manifold Freeze Dryer

Zoo li txhua lub tshuab ziab khaub ncaws lub tshuab ziab khaub ncaws manifold muaj 4 yam yooj yim.Cov no yog:

· Chaw nres tsheb ntxiv khoom

· Condenser

· Nqus

· Tswj System

Cov Khoom Ntxiv Chaw Nres Tsheb
Qhov chaw nres tsheb ntxiv cov khoom yog cov khoom siv uas qhia cov khoom rau lub tshuab ziab khaub ncaws khov.Nyob rau hauv cov ntaub ntawv ntawm ib tug manifold system cov khoom ntim yog feem ntau flasks.Cov khoom yog muab tso rau hauv lub hwj thiab feem ntau statically khov nyob rau hauv ib tug tsawg kub da dej los yog lub freezer.Peb yuav tham txog cov kev xaiv khov hauv qhov tob ntxiv tom qab hauv daim ntawv thev naus laus zis no.

Lub Condenser
Lub condenser nyob rau hauv yuav luag tag nrho cov niaj hnub freeze dryers yog ib tug refrigerated nto uas pab tsav lub sublimation txheej txheem los ntawm tsim ib tug

txo qhov chaw siab hauv lub tshuab ziab khaub ncaws.Lub condenser kuj ua hauj lwm rau ntxiab ya raws / cov kuab tshuaj thiab yog li tiv thaiv lawv los ntawm kev mus rau lub tshuab nqus tsev twj.Cov tshuab ziab khaub ncaws feem ntau muaj nyob rau hauv "ib theem"

(ib qho compressor), "ob theem" ​​(ob compressors) los yog "ob theem sib xyaw" (ob compressors nrog tshwj xeeb sib xyaw roj).Qhov kub siab tshaj plaws ntawm -48C (rau ib chav tsev ib theem) txog -85C (ob theem system) tsis tshua muaj.Qee qhov kev sib xyaw ua ke tuaj yeem ua tiav txawm tias qis dua, xws li -105C.Nws yog ib qho tseem ceeb kom nkag siab tias qhov vapor siab tshaj dej khov tsis yog ib txoj kab nkhaus.Raws li qhov kub thiab txias tau qis dua, txoj cai ntawm kev txo qis rov qab siv tau.

Lub tshuab nqus tsev vacuum thiab lub tshuab nqus tsev twj
Lub vapor siab tshaj dej khov ntawm -48C yog sib npaug rau 37.8 mT.Ntawm -85C nws yog 0.15 mT uas txhais mus rau qhov sib txawv ntawm kwv yees li 37.65

mT.Koj tuaj yeem pom txawm li cas los xij tias qis dua -85C qhov ntsuas kub qis tsuas yog tsim qhov qis qis qis hauv siab - hauv kaum thiab pua pua ntawm milliTorr.Qhov tseeb, feem ntau vapor siab tshaj cov ntxhuav dej khov uas tau luam tawm nres ntawm kwv yees li -80C vim tias thaum kub qis dua qhov sib txawv ntawm qhov tsis tseem ceeb.

Lub tshuab nqus tsev twj tso kua mis rau feem ntau manifold freeze dryers yog ob theem rotary vane roj kaw lub tshuab nqus tsev twj.Lub tshuab nqus tsev twj tso kua mis ib lub hom phiaj thaum lub sij hawm feem ntau ntawm lub freeze drying txheej txheem yog tshem tawm cov uas tsis yog-condensable vapors (nitrogen, oxygen, carbon dioxide li al) los ntawm lub freeze dryer.Los ntawm kev tshem tawm cov roj uas tsis yog condensable nyob rau hauv lub cev lub tshuab nqus tsev twj tso kua mis pab tsim ib puag ncig rau sublimation (dej mus rau vapor yam tsis tau mus txog theem ua kua)

tshwm sim.Vim tias tag nrho cov tshuab ziab khaub ncaws muaj cov xau (virtual to-outgassing los ntawm stainless hlau (yog nws yuav outgas), gaskets, acrylics li al thiab tiag-me ntsis pinhole leaks ntawm ntau yam configurations thiab qhov chaw nyob rau hauv lub system, xws li ntawm lub tshuab nqus tsev raj sib txuas ntawm lub condenser thiab lub tshuab nqus tsev twj) lub tshuab nqus tsev twj tso kua mis ua haujlwm tas li thoob plaws hauv lub voj voog kom qhuav.Raws li txoj cai, yog tias lub tshuab ziab khaub ncaws khov tau tag nrho thiab tsis muaj paug, thaum lub tshuab nqus tsev twj tso kua mis ua qhov pib rub nws tuaj yeem muab tua thiab tsis siv ntxiv mus txog thaum kawg ntawm kev khiav.Nyob rau hauv lub neej tiag no yog tsis tau.

Tswj System
Kev tswj hwm ntawm lub tshuab ziab khaub ncaws khov tau dhau los ua qhov tseem ceeb hauv kev sib txawv ntawm ib lub tshuab ziab khaub ncaws mus rau lwm qhov.Tus nqi ntawm automation thiab cov neeg siv kev phooj ywg tuaj yeem sib txawv ntawm ib lub tshuab mus rau lwm qhov.Txawm hais tias hom twg, nws raug pom zoo tias tsis siv neeg rau thiab tsis siv neeg tawm yog ib feem ntawm tus tswj lub peev xwm.Hauv cov chaw soj nstuam uas siv cov tshuab ziab khaub ncaws ntau tshaj plaws, kev ziab kom qhuav yog ib txoj kev mus rau qhov kawg thiab tsuas yog lwm cov txheej txheem hauv cov npe ntev ntawm cov txheej txheem uas tib neeg yuav tsum siv kom ua tiav lawv cov hom phiaj.Tsis yog txhua tus yog tus kws tshaj lij tshuab ziab khaub ncaws.Muaj qhov tsis siv neeg qhib thiab kaw ua haujlwm pab kom paub tseeb tias qhov kev pib thiab kaw kom zoo yog siv los muab kev tiv thaiv thiab kev ua haujlwm ntev.
