Laboratory Freeze Dryer Workflow

Kev ceev faj rau Laboratory Freeze Dryer

1. Laboratory freeze dryer yuav tsum siv lub qhov hluav taws xob ywj pheej thiab muaj cov av zoo.
2. Lub tshuab ziab khaub ncaws txias yuav tsum ua haujlwm ntawm qhov kub thiab txias ntawm 5-30 degree c, uas yuav pab txuas lub neej ntawm compressor. Yog tias lub compressor siab tshaj 30 degree c rau lub sijhawm ntev, nws yuav ua rau lub compressor puas.
3. Qhov thib ob pib ntawm lub tub yees yuav tsum tau ua tom qab 3 feeb, uas muaj txiaj ntsig zoo rau lub neej ntawm cov xovxwm.
4. Yog tias lub tais thiab cov fwj dej khov rau sab nraud siv tib lub sijhawm, muab cov ntaub ntawv pallet ua ntej, tos ib nrab teev tom qab thaum qhov txias txias yog -50 degree lossis -80 degree thiab lub siab yog 30mTorr, thiab tom qab ntawd ntxiv cov fwj dej khov rau sab nraud kom tsis txhob yaj cov khoom siv hauv lub raj mis.
5.Cov ntaub ntawv yuav tsum yog khov khov, thiab qhov kub thiab txias ua ntej yuav tsum qis dua -30 degree . Khov qhuav cov qauv uas tsis muaj dej soluble tshuaj (xws li cov organic soluble) los yog siab concentration suab thaj ntau tshaj 80% thiab lwm yam qauv uas tsis yooj yim rau khov yuav tsum yog rau pre-freezing nyob rau hauv tsev hauv qab no -80 degree, lub pre - Lub sijhawm khov yuav tsum tsis pub tsawg dua 24 teev, nyiam dua ntau dua 48 teev.
6.Thaum tshem tawm cov plexiglass khov kom qhuav chamber, nws yuav tsum tau muab tso rau ntawm cov khoom muag muag xws li roj hmab kom tsis txhob muaj kev puas tsuaj rau lub plexiglass thiab lub tshuab nqus tsev.
7. Tus nqi ntawm cov ntaub ntawv muab tso rau yog cuam tshuam nrog qhov kub thiab txias. Nws yog ib txwm ua rau qhov txias txias yog -55 degree rau -40 degree lossis -85 degree rau -80 degree thiab lub tshuab nqus tsev yog 5-100mTorr.
8. Thaum huab cua backfilling, thov kho lub tshuab nqus tsev backfilling gas siab kom qis dua 0.5Kg.
9.Qhov kev ncua deb ntawm qhov chaw kuaj lub tshuab ziab khaub ncaws thiab phab ntsa yog ntau dua lossis sib npaug li 30cm.
10.Nws yog txwv tsis pub muab lwm cov khoom siv hluav taws xob dissipation nyob ze ntawm chav kuaj lub tshuab ziab khaub ncaws uas yuav ua rau lub tub yees tsis tuaj yeem ua kom tsis muaj cua sov, ua rau lub ntsuas hluav taws xob tsis ua haujlwm thiab lub compressor puas.
11. Tom qab cov cuab yeej tau muab tso rau hauv qhov chaw ruaj khov, nias lub khawm caster.
12.Saib xyuas cov roj qib thiab roj zoo ntawm lub tshuab nqus tsev twj ua ntej ua haujlwm.
13.Nqus Q. thaiv cov kav dej thiab kaw lub tshuab adapter. Txwv tsis pub, lub tshuab nqus tsev twj yuav puas.
