Peb txhua tus paub txog kev sivrotary evaporatorshauv kev lag luam, tab sis lawv puas tuaj yeem siv tau thaum hloov cov evaporators thiab cua txias condensers (qib: cov khoom siv hluav taws xob sib pauv)?
Kev hloov dua siab tshiab thiab siv cov evaporator teb thiab cua txias condenser (qib: cov khoom siv hluav taws xob sib pauv) yog ib nrab thiab ib nrab, txawm hais tias ob qho tib si rotary evaporator thiab cua txias condenser (qeb: cov khoom siv hluav taws xob hloov hluav taws xob) belongs rau hom kev hloov hluav taws xob theem. Instrumentation, tab sis txawv heev nyob rau hauv lawv yam txog thermal mechanisms. Rotary evaporator yog hluav taws xob tswj kom tig lub khob ntawm qhov nrawm ntawm qhov tsim nyog tshaj plaws kom ua rau thaj tsam evaporation. Lub hwj evaporation yog muab tso rau hauv qhov tsis zoo siab los ntawm lub tshuab nqus tsev twj. Lub raj mis evaporation yog muab tso rau hauv ib da dej rau qhov kub thiab txias thaum tig, thiab cov tshuaj nyob rau hauv lub raj mis yog rhuab, diffused thiab evaporated nyob rau hauv lub rotating flask nyob rau hauv tsis zoo siab. Rotary evaporators feem ntau yog siv rau kev ua kom tsis tu ncua ntawm ntau qhov ntawm cov kuab tshuaj volatile nyob rau hauv qhov txo qis. Tshwj xeeb, cov khoom siv tshuaj tiv thaiv tuaj yeem sib cais thiab ua kom huv los ntawm kev tsom mus rau cov extract thiab distilling cov kua tau txais thaum chromatographic sib cais. Lub hauv paus ntsiab lus tseem ceeb yog lub tshuab nqus tsev distillation, uas yog, nyob rau hauv lub siab txo, thaum cov kuab tshuaj distilled, lub distillation flask yog tsis tu ncua rotating. Rotary evaporator txhais: Ib qho cuab yeej rau kev ceev ceev ntawm cov qauv ua kua. Cov qauv yog rhuab, decompressed, thiab tsis tu ncua rotated nyob rau hauv ib tug spherical iav thawv kom lub evaporation nto cheeb tsam thiab ua kom lub evaporation tus nqi. Lub evaporation kub, evaporation cheeb tsam, mechanism, thiab lwm yam ntawm lub teb evaporator, raws li zoo raws li lwm yam structural yam ntawm lub txias muaj peev xwm, yog tag nrho cov teeb meem uas yuav tsum tau xav txog thaum tsim lub teb evaporator, thiab yuav tsum tau ua nruj me ntsis tswj kev ua hauj lwm thiab zam. txhua yam teeb meem uas yuav tshwm sim thaum lub evaporator ua haujlwm. Condensers (qib: cov khoom siv hluav taws xob sib pauv) tsom ntau dua rau kev hloov pauv hluav taws xob (kev ua tau zoo) thiab tub yees. Hauv qhov no, lawv txawv ntawm evaporators. Lub condenser yuav tsum xav txog lub tub yees thaum hloov cov cua sov, thiab nws kuj yuav tsum xav txog kev hloov pauv thaum lub tub yees. Ob leeg yog inseparable. Tab sis feem ntau hais lus, cov kev xav tau ntawm cov evaporators teb thiab condensers tseem txawv. ** Muaj ntau lossis tsawg dua qhov txawv ntawm lwm yam. Yog hais tias lub evaporator teb thiab condenser yuav tsum tau hloov, yuav tsum muaj plaub-txoj kev thim rov qab valve.
Cov evaporator thiab cua txias condenser tuaj yeem siv sib hloov tau?
