Nkag siab txog Rotovap

Lub rotovap yog ib qho cuab yeej siv tau zoo siv hauv cov chaw kuaj mob kom evaporate cov kua los ntawm kev txo qhov siab thiab siv cua sov thaum tig cov kua hauv lub nkoj, xws li lub khob ntim hauv qab. Cov txheej txheem no yog qhov tseem ceeb rau cov dej num xws li tshem tawm cov kuab tshuaj, qhov concentration, thiab ziab ntawm cov qauv. Qhov txo qis ua kom yooj yim evaporation ntawm qhov kub thiab txias qis dua qhov yuav tsum tau nyob rau hauv ib txwm atmospheric tej yam kev mob, yog li txo qhov decomposition ntawm cov khoom tsis ruaj khov.

 

Lub rotovap ua haujlwm ntawm kev sib xyaw ntawm cov hauv paus ntsiab lus uas suav nrog kev txo qis, kev siv cua sov, thiab kev sib hloov. Nov yog qhov ze dua ntawm txhua qhov:

◆ Txo qhov siab: Los ntawm kev txo qis hauv lub evaporation chamber, lub boiling point ntawm cov kua yog txo. Qhov no tso cai rau evaporation tshwm sim ntawm qhov kub thiab txias qis dua li ntawm atmospheric siab, uas yog tshwj xeeb tshaj yog zoo rau cov cua sov-sensitive tebchaw.

◆ Kev siv cua sov: Thaum tshav kub kub yog muab rau cov kua ntawm lub da dej los yog lub tsho cua sov nyob ib ncig ntawm lub evaporation flask. Qhov kub ntawm lub da dej yog ua tib zoo tswj kom tswj tau qhov xav tau evaporation tus nqi tsis ua rau decomposition.

◆ Kev sib hloov: Lub raj mis uas muaj cov kua yog tig tsis tu ncua. Qhov kev txiav txim no ua haujlwm rau ob lub hom phiaj: nws ua rau thaj tsam ntawm qhov chaw raug evaporation, yog li txhim kho tus nqi evaporation, thiab nws txo qis cov nyhuv ntawm "bumping," uas yog qhov tawg ntawm vaporization uas tuaj yeem tawg cov kua dej.
