Kev ua haujlwm ntawm Rotary Evaporator
Kev npaj:Ruaj ntseg txuas lub evaporation flask rau lub rotating mechanism thiab muab tso rau hauv lub cua sov da dej. Txuas lub condenser rau lub hwj thiab xyuas kom zoo sealing kom muaj kev ruaj ntseg ntawm lub tshuab nqus tsev.
Sample Loading:Ntxiv cov qauv uas muaj cov kuab tshuaj evaporated rau hauv lub evaporation flask. Xyuas kom meej tias lub khob dej tsis dhau los ua kom muaj kev ntxhov siab thiab evaporation.
Cua sov:Pib cua sov lub da dej mus rau qhov xav tau kub. Cov cua sov ua kom yooj yim rau evaporation ntawm cov kuab tshuaj los ntawm cov qauv.
Kev sib hloov:Pib rotating lub hwj ntawm ib tug nruab nrab ceev kom qhov chaw saum npoo raug tshav kub thiab txhawb nqa evaporation npaum. Kev sib hloov ceev tuaj yeem hloov kho raws li cov qauv qauv thiab tus nqi evaporation.
Vacuum Application:Qhib lub tshuab nqus tsev twj tso kua mis kom txo qhov siab hauv qhov system. Qhov no txo qhov kub ntawm cov kuab tshuaj, pab nyob rau hauv sai evaporation thaum txo tshav kub raug rau cov qauv.
Saib xyuas:Saib xyuas cov txheej txheem evaporation, kho qhov tsis xws li qhov kub thiab txias, kev sib hloov ceev, thiab lub tshuab nqus tsev raws li xav tau los ua kom zoo dua cov kuab tshuaj tshem tawm thiab cov qauv concentration.
Sau:Cov kuab tshuaj condensed sau nyob rau hauv lub ntim ntim, thaum cov qauv concentrated tseem nyob rau hauv lub evaporation flask. Thaum cov evaporation tiav, nres qhov kev sib hloov thiab cua sov, thiab ua tib zoo tshem tawm cov qauv thiab khaws cov kuab tshuaj rau kev ua haujlwm ntxiv lossis kev tshuaj xyuas.
NtantawmRotary Evaporators
Rotary evaporatorstuaj nyob rau hauv ntau qhov ntau thiab tsawg thiab configurations, txhua tailored rau tej yam kev kuaj. Cov yam ntxwv tseem ceeb los xav txog thaum xaiv rotovap suav nrog:
