Dab tsi yog cov ntsiab lus tseem ceeb ntawm Rotary Evaporator?
Lub evaporator teb muaj ntau yam tseem ceeb, txhua tus ua lub luag haujlwm tseem ceeb hauv cov txheej txheem evaporation. Kev nkag siab txog cov khoom siv no yog qhov tseem ceeb rau kev siv thiab tu cov cuab yeej kom raug.
Rotary Flask thiab Vapor Duct
Lub raj mis teb yog qhov twg cov qauv muab tso rau evaporation. Nws txuas nrog rau lub vapor duct, uas tig los xyuas kom meej txawm tias cua sov thiab tiv thaiv kev sib tsoo (nrog kub kub). Qhov kev sib hloov no ua kom yooj yim rau thaj chaw loj dua rau evaporation, ua rau cov txheej txheem ua haujlwm zoo dua.
Thermal Bath
Cov chav da dej cua sov, feem ntau ntim nrog dej lossis roj, yog siv los ua kom sov lub khob ntim dej. Qhov kub ntawm lub da dej yog qhov tseem ceeb heev vim nws yuav tsum tau tswj kom tsis txhob degradation ntawm cov qauv thaum ua kom cov evaporation zoo.
Lub Condenser
Lub condenser cools lub vapor generated los ntawm cov qauv, tig nws rov qab mus rau hauv ib tug kua uas yog sau nyob rau hauv ib tug txais lub hwj. Muaj ntau hom condensers, xws li ntsug, kab pheeb ces kaum, thiab txias ntiv tes condensers, txhua tus haum rau kev siv sib txawv.
Lub Taub Hau
Lub khob ntim tau sau cov kua condensed. Nws yog ib qho tseem ceeb uas yuav tsum tsis tu ncua xyuas thiab muab lub khob ntim pov tseg kom tsis txhob hla dhau thiab ua kom muaj kev ua haujlwm tas mus li.
Lub tshuab nqus tsev vacuum
Lub tshuab nqus tsev ua kom qis qis hauv lub siabrotary evaporator, txo qhov kub kub ntawm cov kuab tshuaj. Qhov no tso cai rau evaporation ntawm qis kub, uas yog tshwj xeeb tshaj yog pab tau rau cov tshav kub-sensitive tebchaw.
Kev nyab xeeb nta
Niaj hnub nimno rotary evaporators tuaj nruab nrog ntau yam kev nyab xeeb nta xws li kev tiv thaiv kub dhau, tsis siv neeg nqa ntawm lub tshuab hluav taws xob, thiab txaws tiv thaiv kom tsis txhob muaj xwm txheej thiab kis kab mob.
Koj Teeb thiab ua haujlwm li cas Rotary Evaporator?
Kev teeb tsa kom raug thiab kev ua haujlwm ntawm cov evaporator teb yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo thiab ua kom muaj kev nyab xeeb hauv chav kuaj.
Kev teeb tsa Rotary Evaporator
Tso lub Rotary Evaporator rau hauv qhov chaw nyab xeeb: Xyuas kom lub cuab yeej nyob hauv qhov chaw uas muaj cua zoo, kom deb ntawm cov khoom siv hluav taws xob thiab qhov chaw tawg. Nws yuav tsum nyob rau ntawm qhov chaw ruaj khov kom tsis txhob muaj kev vibrations uas tuaj yeem ua rau tawg lossis raug xwm txheej.
Npaj lub rhaub dej kub: Sau cov cua kub da dej nrog cov kua dej uas tsim nyog (dej lossis roj) thiab muab tso rau qhov kub uas xav tau. Xyuas kom lub da dej kub yog haum rau cov kuab tshuaj evaporated.
Txuas lub Rotary Flask: Txuas lub raj xa dej kom ruaj ntseg uas muaj cov qauv mus rau lub vapor duct. Xyuas kom nws nruj nreem kaw kom tsis txhob muaj qhov xau.
Txuas lub Condenser thiab Receiving Flask: Txuas lub condenser thiab txais lub hwj, kom ntseeg tau tias txhua qhov kev sib txuas yog nruj thiab ruaj ntseg. Tshawb xyuas seb puas muaj qhov xau.
Teem Lub Tshuab Nqus Tsev: Txuas lub tshuab nqus tsev twj rau lubrotary evaporatorthiab xyuas kom txhua qhov kev sib txuas muaj kev ruaj ntseg. Maj mam siv lub tshuab nqus tsev kom tsis txhob muaj kev hloov pauv sai sai uas tuaj yeem ua rau pob.
Ua haujlwm Rotary Evaporator
Pib qhov kev sib hloov: Pib rotating lub hwj rotary ntawm ib tug nruab nrab ceev. Kev sib hloov ua kom muaj cua sov thiab ua rau thaj tsam ntawm evaporation.
Kub tus qauv: Maj mam nce qhov kub ntawm lub rhaub dej kom pib evaporation. Saib xyuas qhov kub thiab txias kom tsis txhob overheating tus qauv.
Kho lub nqus tsev vacuum: Maj mam nce lub tshuab nqus tsev kom txo qhov kub ntawm qhov hnyav. Saib xyuas cov txheej txheem kom ntseeg tau tias cov evaporation du tsis muaj pob lossis txaws.
Sau cov Condensed Solvent: Cov kuab tshuaj vapor yuav condense nyob rau hauv lub condenser thiab sau nyob rau hauv lub txais lub hwj. Tsis tu ncua xyuas thiab muab lub khob ntim dej kom tsis txhob ntws tawm.
Saib xyuas cov txheej txheem: Tsis tu ncua saib xyuas cov txheej txheem evaporation, kho qhov kub thiab txias, kev sib hloov ceev, thiab lub tshuab nqus tsev raws li xav tau kom ua haujlwm tau zoo thiab nyab xeeb.
