Jul 18, 2024
Tso lus
A rotary evaporator, feem ntau cog lus raws li rotovap, yog ib lub chaw tshawb fawb contraption siv rau cov khoom tsim thiab ilv tshem tawm cov kuab tshuaj los ntawm kev ntsuam xyuas los ntawm dissipation. Hauv chemistry, biochemistry, thiab lwm yam kev tshawb fawb, cov txheej txheem no nquag siv. Cov txheej txheem tom qab revolving dissipation suav nrog txo qis kom txo qis cov npoo ntawm cov dej npau npau ntawm cov kuab tshuaj, tso cai rau lawv kom ploj ntawm qhov kub thiab txias. Cov txheej txheem no yog tshwj xeeb tshaj yog pab rau cov cua sov-touchy sib tov.
Txoj Cai ntawm Rotary Evaporation
Basic tswvyim
Lub hauv paus ntsiab lus ntawm rotavap yog los txo cov siab nyob rau hauv lub system, uas nyob rau hauv lem txo lub boiling point ntawm cov kuab tshuaj. Qhov no tso cai rau cov kuab tshuaj evaporate ntawm qhov kub thiab txias ntau dua li qhov nws xav tau nyob rau hauv ib txwm atmospheric siab.
Cov cuab yeej muaj ntau yam tseem ceeb uas ua haujlwm ua ke kom ua tiav qhov txiaj ntsig no.
Cov ntsiab lus tseem ceeb
Lub rotating flask yog qhov uas tus qauv muab tso rau. Los ntawm rotating, lub hwj tsub kom qhov chaw saum npoo ntawm cov qauv, txhawb kom ceev evaporation. Qhov kev sib hloov no kuj tseem pab faib cov cua sov kom sib npaug thiab tiv thaiv kev sib tsoo, uas tuaj yeem tshwm sim thaum cov kuab tshuaj boils heev.
Lub pas dej da dej muab ib qho chaw zoo sib xws thiab tswj tau qhov cua sov rau lub rotating flask. Cov cua sov los ntawm cov dej da dej ua kom yooj yim rau evaporation ntawm cov kuab tshuaj. Qhov kub ntawm cov dej da dej feem ntau yog teem rau hauv qab ntawm qhov kub ntawm cov kuab tshuaj nyob rau hauv qhov txo qis.
Lub condenser yog siv los ua kom txias cov vaporized hnyav, hloov nws rov qab rau hauv cov kua ua kua. Nws yog feem ntau sau nrog qhov nruab nrab cua txias, xws li dej lossis dej khov qhuav, kom ua tiav cov dej ntws zoo. Tom qab ntawd cov kuab tshuaj condensed yog sau rau hauv ib lub raj mis uas tau txais cais.
Lub tshuab nqus tsev yog qhov tseem ceeb rau kev txo qis hauv cov evaporator teb. Los ntawm kev txo qis, qhov kub ntawm cov kuab tshuaj yog txo, cia nws evaporate ntawm qhov kub thiab txias. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov khoom siv hluav taws xob kub-rhiab heev uas tuaj yeem degrade ntawm qhov kub siab dua.
Lub rotavap ua haujlwm los ntawm kev muab cov qauv tso rau hauv lub khob rotating, uas tom qab ntawd submerged hauv cov dej kub da dej. Raws li lub hwj rotates, cov kuab tshuaj evaporates nyob rau hauv lub siab txo, thiab cov vapor yog coj mus rau hauv lub condenser. Qhov nruab nrab cua txias hauv lub condenser cools lub vapor, tig nws rov qab mus rau hauv cov kua daim ntawv, uas yog ces sau nyob rau hauv lub txais lub hwj.
Kev siv ntawm Rotary Evaporators
Kev tshem tawm hnyav
Ib qho ntawm cov kev siv tseem ceeb ntawm rotavaps yog tshem tawm cov kuab tshuaj los ntawm cov qauv. Qhov no yog qhov tseem ceeb hauv ntau qhov chaw, suav nrog cov tshuaj, qhov twg cov khoom xyaw nquag yuav tsum tau cais tawm ntawm cov kuab tshuaj. Lub efficiency ntawm lub rotary evaporator ua rau nws zoo tagnrho rau lub hom phiaj no.
Sample Concentration
Sample concentration siv rotavaps yog ib qho tseem ceeb nyob rau hauv ntau yam scientific thiab industrial daim ntaub ntawv.
