Ib qho cuab yeej tseem ceeb hauv Chemical thiab Pharmaceutical Laboratories

Rotary evaporators, tseem hu ua rotavaps lossis rotavapors, yog cov cuab yeej tseem ceeb hauv cov chaw kuaj tshuaj thiab tshuaj. Cov cuab yeej no tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau cov distillation ntawm cov kuab tshuaj tsis haum rau hauv kev txo qis, ua kom yooj yim rau cov concentration thiab purification ntawm cov tshuaj tiv thaiv. Ntawm cov kev siv ntau yam ntawm rotary evaporators, distillation ntawm ethanol sawv tawm vim nws siv dav hauv cov organic synthesis, kev tsim tshuaj, thiab cov txheej txheem hnyav rov qab.

 

Kab lus no yog tsim los muab cov ntsiab lus dav dav ntawm ethanol rotary evaporator, npog nws cov hauv paus ntsiab lus, kev tsim kho, cov txheej txheem ua haujlwm, qhov zoo, qhov tsis zoo, thiab kev siv.

 

Lub hauv paus ntsiab lus ntawm rotary evaporator yog lub tshuab nqus tsev distillation. Cov txheej txheem no suav nrog cua sov cov kuab tshuaj mus rau nws qhov kub kub hauv qhov txo qis, uas yog qis dua atmospheric siab. Lub khob distillation, feem ntau yog ib puag ncig-hauv qab lossis Eggplant flask nrog tus qauv hauv av-iav sib koom, yog txuas txuas ntxiv thaum lub sijhawm distillation. Qhov kev sib hloov no tsim ib zaj duab xis nyias ntawm cov tshuaj nyob rau sab hauv phab ntsa ntawm lub khob, txhim kho tus nqi evaporation los ntawm kev ua kom cov cheeb tsam raug tshav kub.

Cov khoom tseem ceeb ntawm rotary evaporator muaj xws li: ● Rotary Tsav: Fais fab kev sib hloov ntawm lub tshuab distillation. ● Evaporation Flask: Tuav cov qauv kev daws teeb meem thiab tig los ua ib zaj duab xis nyias. ● Evaporation Tube: Txhawb lub raj mis thiab tso cai rau lub tshuab nqus tsev los kos tawm cov kuab tshuaj evaporated. ● Lub Tshuab Nqus Tsev: Txo qhov siab hauv qhov system kom txo qhov kub ntawm qhov hnyav. ● Da dej cua sov: Muab cua sov rau lub tshuab distillation, feem ntau yog los ntawm dej lossis roj. ● Condenser: Txias cov kuab tshuaj evaporated, hloov nws rov qab mus rau hauv daim ntawv ua kua. ● Lub khob ntim khoom: Sau cov kuab tshuaj condensed.   Nyob rau hauv cov ntaub ntawv ntawm ethanol distillation, lub teb evaporator ua hauj lwm los ntawm kev txo lub siab nyob rau hauv lub system, txo lub boiling point ntawm ethanol. Lub distillation flask, muaj ib tug sib tov ntawm ethanol thiab lwm yam compounds, yog rhuab thaum tig. Kev sib hloov ua rau nyias zaj duab xis ntawm qhov sib tov ntawm lub khob dej hauv phab ntsa, uas tso cai rau cov cua sov hloov mus rau qhov zoo thiab evaporation. Tom qab ntawd cov ethanol evaporated yog condensed thiab sau nyob rau hauv lub receiver flask.

Rotary evaporators yog tsim los kom muaj txiaj ntsig zoo thiab muaj kev nyab xeeb distillation ntawm cov kuab tshuaj volatile. Kev tsim kho thiab tsim qauv ntawm cov cuab yeej no tsom rau kev tsim kom muaj kev tswj hwm ib puag ncig rau cov txheej txheem distillation, suav nrog kev tswj siab, kev tswj xyuas qhov kub thiab txias, thiab kev ua kom zoo.

● Rotary Motor thiab Flask Rotation

Lub cev muaj zog teb yog lub plawv ntawm lub evaporator, muab lub zog xav tau los tig lub khob distillation. Lub hwj rotates ntawm qhov ceev tsis tu ncua, feem ntau ntawm 50 thiab 160 revolutions ib feeb (rpm), tsim ib zaj duab xis nyias ntawm cov tshuaj ntawm nws phab ntsa sab hauv. Cov zaj duab xis nyias no ua rau thaj tsam ntawm qhov chaw raug tshav kub, txhawb nqa evaporation zoo.

● Chav da dej kub

Lub chav da dej cua sov, feem ntau yog ntim nrog dej los yog roj, nyob ib puag ncig lub khob distillation thiab muab cov cua sov tsim nyog rau evaporation. Qhov kub ntawm lub rhaub dej kub tuaj yeem tswj tau siv lub ntsuas cua sov, uas tso cai rau kev tswj hwm ntawm cov txheej txheem distillation. Rau ethanol distillation, lub cua sov da dej kub yog hloov mus rau me ntsis saum toj no lub boiling point ntawm ethanol nyob rau hauv lub xav tau nqus tsev vacuum.

● Lub Tshuab Nqus Tsev

Lub tshuab nqus tsev yog qhov tseem ceeb rau kev txo qis hauv cov evaporator, uas ua rau txo qis qhov kub ntawm qhov hnyav. Lub tshuab nqus tsev tuaj yeem tsim tau siv lub tshuab nqus dej lossis lub tshuab nqus tsev twj. Lub siab nyob rau hauv lub evaporator tuaj yeem hloov kho siv lub tshuab nqus tsev, tso cai rau kev tswj xyuas meej ntawm cov txheej txheem distillation.

● Condenser thiab Collection Flask

Lub condenser yog lub luag hauj lwm rau txias cov evaporated hnyav, converting nws rov qab mus rau hauv ib tug kua daim ntawv. Lub condenser feem ntau yog iav coil txias los ntawm dej lossis dej khov, kom ntseeg tau tias muaj txiaj ntsig zoo ntawm cov kuab tshuaj vapor. Cov kuab tshuaj condensed yog tom qab ntawd sau rau hauv lub khob ntim khoom, uas tuaj yeem tshem tau yooj yim thiab hloov raws li xav tau.

 

Rotary evaporators muaj ntau yam kev siv hauv cov chaw kuaj tshuaj thiab chaw muag tshuaj, suav nrog cov distillation ntawm ethanol. Hauv qab no yog qee qhov kev siv tseem ceeb ntawm rotary evaporators: ● Organic Synthesis: Hauv cov organic synthesis, rotary evaporators yog siv los tshem tawm cov kuab tshuaj volatile los ntawm cov tshuaj sib tov sib xyaw, ua kom huv thiab cais cov khoom siv tshuaj tiv thaiv.
