Dab tsi yog 20 40 60 Txoj Cai Rau Rotovap?

Txoj cai "20-40-60" yog cov lus qhia dav dav siv hauv kev ua haujlwm ntawm rotary evaporators(rotovaps) los pab ua kom cov kuab tshuaj evaporation muaj txiaj ntsig zoo thaum txo qhov kev pheej hmoo ntawm cov qauv poob lossis kev puas tsuaj. Nws yog hais txog qhov pom zoo ua ntu zus ntawm kev hloov kho rau cov haujlwm tseem ceeb ntawm cov

 

20% Revolution Ceev:Pib nrog qhov nruab nrab moo tig ceev, tsis tu ncua nyob ib ncig ntawm 20% ntawm qhov ceev tshaj plaws. Qhov no tso cai rau kev cuam tshuam me me ntawm qhov kev sim thaum txo qis qis los yog frothing, tshwj xeeb tshaj yog tias qhov kev sim yog tuab los yog inclined rau shaping npuas.

 

40% Da dej kub:Teem lub da dej kub rau roughly 40% ntawm qhov bubbling point ntawm lub dissolvable yog dissipated. Qhov no ua rau kom sov txaus los txhawb kom dissipation yam tsis muaj overheating qhov kev ntsuam xyuas los yog ua rau saum toj kawg nkaus bumping. Hloov cov da dej kub raws li qhov tshwj xeeb dissolvable yog dissipated thiab nws cov bubbling point.

 

60% Vacuum Level:Maj mam txo qhov hnyav sab hauv lub evaporator tig mus rau kwv yees li 60% ntawm qhov ua tau zoo tshaj plaws ntawm lub tshuab nqus tsev. Nqa qhov hnyav ua rau qhov sib txawv qis dua qhov bubbling point ntawm lub dissolvable, nce nrawm dua vanishing. Txawm li cas los xij, dhau ntawm lub tshuab nqus tsev sab saum toj tuaj yeem ua rau kev sim debasement lossis bumping, yog li nws tseem ceeb heev kom pom qhov sib npaug.

 

Tom qab teeb tsa qhov pib tsis pom zoo rau 20-40-60 khiav cov yeeb yam, koj tuaj yeem hloov kho tsis tu ncua raws li cov yam ntxwv tshwj xeeb ntawm qhov kev sim thiab qhov ua kom tawg tau ploj mus. Rau cov ntaub ntawv, yog tias vanishing zoo li nruab nrab, koj tuaj yeem nce qhov nrawm nrawm lossis nce qhov kub ntawm da dej marginally. Hloov pauv, yog tias qhov kev sim no yog pob los yog frothing, koj yuav tsum tau txo qis lub tshuab nqus tsev lossis txo qhov kub ntawm da dej.

 

Nws yog ib qho tseem ceeb los tshuaj xyuas cov dissipation npaj ze thiab ua kev hloov pauv raws li qhov yuav tsum tau ua kom ua tiav qhov zoo tshaj plaws los txog thaum lav qhov kev ruaj ntseg thiab kev ua siab zoo ntawm qhov kev sim. Ntxiv mus, qhov 20-40-60 khiav cov yeeb yam yog qhov pib taw qhia rau cov neeg siv tsis tau ua haujlwm ntawm cov evaporators, muab txoj hauv kev zoo rau kev ua kom zoo tshaj qhov kev npaj.

 

Nkag siab txog Rotovap: Lub Ntsiab Tseem Ceeb

Rotary evaporation, feem ntau hu ua rotovap, yog cov txheej txheem tseem ceeb hauv chav kuaj rau kev cais cov kuab tshuaj los ntawm cov qauv. Nws yog ib qho cuab yeej tseem ceeb rau kev tsom, purifying, thiab cais cov tebchaw, dav siv hauv ntau yam kev qhuab qhia. Txoj cai 20 40 60 rau rotovap sawv cev rau lub hauv paus ntsiab lus qhia kev ua haujlwm ntawm cov cuab yeej no, ua kom cov txiaj ntsig zoo hauv cov txheej txheem kuaj.

Deciphering the 20 40 60 Txoj Cai: Ib Txoj Kev Ua Tau Zoo

Txoj cai 20 40 60 yog txoj cai ntawm tus ntiv tes xoo feem ntau ua haujlwm los ntawm cov kws tshawb fawb los ua kom yooj yimrotary evaporationtxheej txheem. Qhov tseem ceeb, nws delineates cov theem ua ntu zus ntawm cov txheej txheem, faib cov sijhawm tshwj xeeb rau txhua theem: 20% rau cua sov, 40% rau lub ntsiab evaporation, thiab 60% rau theem condensation. Txoj cai no yog txhawm rau ua kom muaj txiaj ntsig zoo tshaj plaws thaum txo qis kev pheej hmoo ntawm tus qauv degradation lossis khoom puas tsuaj.

Txoj cai 20-40-60 muab ib txoj hauv kev rau kev khiav hauj lwm cov evaporator (rotovap) ua tau zoo thiab muaj txiaj ntsig. Cia peb rhuav tshem txhua yam ntawm txoj cai thiab nws cov txiaj ntsig zoo:

20% Kev sib hloov ceev:

Daim Ntawv Thov: Pib nrog kev sib hloov ceev uas yog kwv yees li 20% ntawm qhov siab tshaj plaws. Qhov no ua kom muaj kev ntxhov siab ntawm tus qauv tsis ua rau muaj kev sib tsoo ntau dhau lossis ua npuas dej, tshwj xeeb tshaj yog rau cov qauv uas muaj viscosity siab lossis nyiam ua npuas.

Kev hloov kho: nce lossis txo qhov kev sib hloov ceev raws li xav tau raws li cov yam ntxwv tshwj xeeb ntawm cov qauv thiab hnyav. Kev sib hloov ceev dua tuaj yeem tsim nyog rau kev evaporation sai dua, thaum qis qis yuav zoo dua rau cov qauv me me.

40% da dej kub:

Daim ntawv thov tswv yim: Teem lub da dej kub rau ib ncig ntawm 40% ntawm lub boiling point ntawm cov kuab tshuaj evaporated. Qhov no muab cov cua sov txaus los pab txhawb evaporation yam tsis muaj overheating tus qauv los yog ua rau pob.

Kev Kho Kom Zoo: Kho qhov kub ntawm da dej raws li qhov kub thiab txias ntawm qhov hnyav thiab qhov xav tau evaporation tus nqi. Qhov kub qis dua tuaj yeem tsim nyog rau cov kuab tshuaj tsis hloov pauv, thaum qhov kub siab dua yuav tsim nyog rau cov kuab tshuaj tawv tawv dua.

60% Vacuum Level:

Daim Ntawv Thov: Maj mam txo qhov siab hauv rotovap mus rau kwv yees li 60% ntawm lub tshuab nqus tsev siab tshaj plaws. Txo lub siab txo qis qhov kub ntawm qhov hnyav, txhawb kom evaporation sai dua.

Kev Kho Kom Zoo: Saib xyuas lub tshuab nqus tsev kom ze thiab kho raws li qhov xav tau los txhim kho cov txheej txheem evaporation. Lub tshuab nqus tsev siab dua tuaj yeem tsim nyog rau evaporation sai dua, tab sis yuav tsum ceev faj kom tsis txhob muaj cov qauv sib tsoo lossis degradation.

Cov Lus Qhia Ntxiv Ntxiv:

Kev soj ntsuam: Tsis tu ncua saib cov txheej txheem evaporation, soj ntsuam cov yam ntxwv xws li hnyav ntim, qauv zoo li qub, thiab tus nqi evaporation.

Kev Nyab Xeeb: Ua raws li cov txheej txheem kev nyab xeeb kom raug thaum ua haujlwm rotovap, suav nrog hnav cov khoom tiv thaiv tus kheej tsim nyog (PPE) thiab ua kom muaj cua txaus.

Sample Integrity: Ua tib zoo tiv thaiv kom tsis txhob muaj cov qauv poob lossis kev sib kis thaum lub sij hawm evaporation, xws li siv cov txheej txheem sealing tsim nyog thiab tsis txhob overheating.

Kev paub dhau los thiab kev sim: Kev hloov kho rau 20-40-60 qhov tsis sib xws yuav txawv nyob ntawm seb yam xws li cov qauv muaj pes tsawg leeg, cov khoom hnyav, thiab cov khoom siv tshwj xeeb. Kev paub thiab kev sim yuav pab kho cov txheej txheem kom tau txais txiaj ntsig zoo.

Ua raws li 20 40 60 Txoj Cai: Cov Kev Cai Zoo Tshaj Plaws thiab Kev Txiav Txim Siab
