Jul 17, 2024
Tso lus
Muaj qhov sib txawv tseem ceeb ntawm rotary evaporation apparatus thiab lub tshuab nqus tsev distillation zoo tib yam nyob rau hauv ntau yam, uas yog feem ntau cuam tshuam los ntawm lub hauv paus ntsiab lus, daim ntawv thov Scope, cov khoom muaj pes tsawg leeg thiab cov yam ntxwv ntawm kev ua haujlwm.

Cov ntsiab cai txawv
Rotary distillation:Rotary distillation yog hluav taws xob tswj los ua kom lub distillation flask tig ntawm qhov ceev ntawm qhov ceev tshaj plaws kom ua rau thaj tsam evaporation. Nyob rau tib lub sij hawm, lub tshuab nqus tsev twj tso kua mis ua rau lub evaporation flask nyob rau hauv lub tsis zoo siab lub xeev, txo lub boiling point ntawm cov tshuaj, thiab yog li accelerates lub evaporation ceev. Rotary steaming combines ob qho tib si kev sib hloov thiab decompression los txhim kho evaporation efficiency.
Ordinary nqus tsev distillation:Lub tshuab nqus tsev distillation (tseem hu ua lub tshuab nqus tsev distillation) feem ntau txo qhov kub ntawm cov kua los ntawm kev txo lub siab nyob rau hauv lub cev, kom tsis txhob muaj kev phiv tshuaj nyob rau hauv cov txheej txheem distillation ntawm high-boiling tshuaj los yog cov tebchaw uas yooj yim rau decompose, oxidize los yog polymerize thaum atmospheric distillation.
