Qhov txawv ntawm Microfiltration Cassette thiab Centrifugation
Qhov txawv ntawm Microfiltration Cassette thiab Centrifugation
1. Taw qhia
Microfiltration membrane yog tsim los ntawm cov ntaub ntawv polymer, uas tuaj yeem lim tawm cov kab mob loj, cov hlwb thiab lwm yam khoom siv organic. Nws plays lub luag haujlwm tseem ceeb hauv biopharmaceuticals. Centrifugation yog ib qho txheej txheem rau kev sib cais nyob rau hauv uas centrifugal quab yuam / acceleration ua rau denser molecules txav mus rau lub periphery, thaum tsawg dua particles txav mus rau qhov chaw. Ob leeg yog cov txheej txheem sib cais, tab sis muaj qee qhov sib txawv ntawm tus nqi.
2.Microfiltration Cassettes VS Centrifugation
(1) Microfiltration membranes yog scalable thiab saj zawg zog dua centrifugation. Microfiltration membranes tuaj yeem siv rau hauv cov khoom me me lossis loj thiab tuaj yeem ua ke tau yooj yim thiab siv tau.
(2) Microfiltration membranes tuaj yeem rov qab siv dua, qhov centrifugation yuav tsum tau hloov cov khoom siv ib ntus.
(3) Microfiltration membranes tsis tas yuav tig ntawm tib qhov kev kub ceev xws li centrifugation, yog li txo cov nqi txij nkawm los ntawm kev siv hluav taws xob tsawg thiab txo qhov kev pheej hmoo ntawm kev ua tsis tiav. Microfiltration membranes kuj tseem tuaj yeem muab cov khoom lag luam zoo sib xws thiab txhim khu kev qha vim muaj kev tswj xyuas ntau dua ntawm cov txheej txheem.
(4) Microfiltration membranes tuaj yeem muaj tus nqi pib nqis peev ntau dua li centrifugation thiab xav tau ntau tus neeg ua haujlwm los ua haujlwm thiab tswj. Qee zaum, centrifugation yuav ua tau zoo dua li microfiltration membranes hauv kev ua cov khoom tshwj xeeb. Yog li ntawd, kev xaiv ntawm kev sib cais tshuab yog nyob ntawm kev sib pauv ntawm cov kev xav tau tshwj xeeb thiab cov txiaj ntsig kev lag luam.
Tus nqi sib piv: Microfiltration Cassettes VS Rotor Centrifuge

Siv 6 centrifuges ua haujlwm tib lub sijhawm. Txhua qhov ntim yog 4L thiab txhua lub sijhawm ua haujlwm yog 30min |
Raws li tuaj yeem pom los ntawm cov lus saum toj no, siv lub hom phiaj ua ntim ntawm 1000L ua piv txwv, hauv 2h-2.5h, siv 20m2 microfiltration cassette, flux yog 20L / m2, tus nqi tsuas yog kwv yees li 300,000. Txawm li cas los xij, siv 6 centrifuges los ua haujlwm tib lub sijhawm, txhua qhov ntim yog 4L thiab txhua lub sijhawm ua haujlwm yog 30min, tus nqi yog li 1,200,000. Nws tuaj yeem pom tau tias kev siv cov microfiltration cassette muaj txiaj ntsig zoo hauv kev txo cov nqi thiab nce kev ua haujlwm.
Qhov zoo ntawm microfiltration cassette
(1) Kev ua kom pom tseeb dua: Microfiltration cassette nrog finer pom pore loj tuaj yeem tshem tawm cov khoom me me thiab cov kab mob thiab txhim kho kev pom zoo.
(2) Yooj yim rau kev khiav lag luam: Microfiltration cassette tuaj yeem siv ua ke nrog ntau yam khoom siv, yooj yim rau nruab, hloov thiab ua haujlwm.
(3) Cov cheeb tsam me me: Txij li cov microfiltration cassette tau siv cov microporous pom ntau, nws qhov chaw pom yog qhov loj, yog li nws thaj chaw nyob yog me dua li cov khoom siv centrifugal pom.
(4) Kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig: Microfiltration cassette tsuas yog xav tau ib qho me me ntawm lub siab los thawb cov kua los ntawm lim membrane. Piv nrog rau centrifugal filtration, nws tsis tas yuav siv hluav taws xob ntau los yog lub zog siv hluav taws xob, kom txuag tau lub zog. Tsis tas li ntawd, nws tsis tsim cov suab nrov thiab kev vibration los ntawm kev sib hloov ceev, uas yog ib puag ncig zoo.
4. Cov lus xaus
Nyob rau hauv luv luv, piv nrog centrifugal pom, microfiltration cassette muaj ntau dua filtration efficiency, me me nyob cheeb tsam, tsawg zog noj thiab yog yooj yim rau kev khiav lag luam.
