Lub tshuab nqus tsev concentrator teb evaporator tuaj yeem cais thiab ntxuav cov khoom siv tshuaj tiv thaiv
Feem ntau yog siv rau cov distillation tsis tu ncua ntawm ntau cov kuab tshuaj volatile nyob rau hauv lub siab txo. Hauv particular, qhov concentration ntawm cov extract thiab distillation ntawm cov kua tau txais thaum lub sij hawm chromatographic sib cais yuav cais thiab purify cov tshuaj tiv thaiv cov khoom. Lub hauv paus ntsiab lus ntawm rotary evaporator 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. Structure: Lub raj mis distillation tuaj yeem yog pear-puab lossis round-bottomed flask nrog tus qauv sib tsoo lub qhov ncauj interface, uas txuas nrog lub twj tso kua mis decompression los ntawm cov reflux serpentine condenser, thiab lwm qhov qhib ntawm reflux condenser yog txuas nrog kev txais. lub raj mis nrog lub qhov ncauj hauv av. Siv tau evaporated organic hnyav. Muaj peb txoj kev piston nruab nrab ntawm lub condenser raj thiab lub twj tso kua mis decompression. Thaum lub kaw lus txuas nrog rau cov cua, lub distillation flask thiab cov kua dej sib txuas tau raug tshem tawm kom hloov cov kuab tshuaj. Thaum lub kaw lus txuas nrog lub twj tso kua mis decompression, lub kaw lus yuav tsum nyob rau hauv lub xeev txo. lub xeev siab. Thaum siv, lub siab yuav tsum tau decompressed ua ntej, thiab tom qab ntawd lub cav yuav tsum tau tig rau tig lub distillation flask. Thaum nws dhau lawm, nws yuav tsum tau nres ua ntej thiab tom qab ntawd muab tso rau hauv qhov chaw kom tsis txhob muaj cov distillation flask poob thaum lub sij hawm tig. Raws li lub tshav kub qhov chaw rau distillation, nws yog feem ntau txawm peem rau nrog ib tug sib xws qhov kub thiab txias tank dej.
Lub purity ntawm lub ntsiab tivthaiv nyob rau hauv lub filtrate filtrate yuav nce, thiab ces cov filtrate yog poured rau hauv ib lub tais evaporating crystallize, thiab cov khoom siv lead ua tau yog ib yam khoom uas muaj zog purity. Dissolve cov khoom kom huv si nrog qhov tsawg tshaj plaws ntawm cov kuab tshuaj kub. Yog hais tias muaj insoluble impurities nyob rau lub sij hawm no, cov tshuaj yuav tsum tau lim nyob rau hauv no sov mob tam sim ntawd; nyob rau hauv no txoj kev, insoluble khoom impurities tuaj yeem tso rau ntawm daim ntawv lim los ntawm kev pom. Lub purity ntawm lub ntsiab tivthaiv nyob rau hauv lub filtrate filtrate yuav tsum tau nce, thiab ces cov filtrate yog poured rau hauv ib lub tais evaporating crystallize, thiab cov khoom siv lead ua yog ib yam khoom muaj zog.
