Yuav Ua Li Cas Xaiv Lub Filter Syringe

Yuav Ua Li Cas Xaiv Lub Filter Syringe

Lub hom phiaj tseem ceeb ntawm cov syringe lim yog lim kua thiab tshem tawm cov khoom, sediments, microorganisms, thiab lwm yam. Lawv tau siv dav hauv biology, chemistry, Environmental science, tshuaj, thiab tshuaj.Cov lim dej no yog nrov rau nws cov txiaj ntsig zoo heev, kev yooj yim thiab kev ua haujlwm zoo.Txawm li cas los xij, xaiv txoj cai lim dej tsis yooj yim thiab yuav tsum tau nkag siab txog cov yam ntxwv ntawm ntau lub lim dej thiab lwm yam cuam tshuam.Kab lus no yuav tshawb txog kev siv cov koob lim dej, cov yam ntxwv ntawm cov ntaub ntawv sib txawv ntawm daim nyias nyias, thiab yuav ua li cas xaiv txoj cai.

• Qhov pore loj ntawm lub lim membrane

1) Lim daim nyias nyias nrog lub pore loj ntawm 0.45 μm: siv rau cov qauv niaj hnub mobile theem pom thiab tuaj yeem ua tau raws li cov kev cai chromatographic.

2) Lim daim nyias nyias nrog lub pore loj ntawm 0.22μm: Nws tuaj yeem tshem tawm cov khoom zoo heev hauv cov qauv thiab cov theem txawb nrog rau tshem tawm cov kab mob.

• Txoj kab uas hla ntawm lim membrane

Feem ntau, feem ntau siv lim membrane diameters yog Φ13μm thiab Φ25μm.Rau cov qauv ntim ntawm 0-10ml, Φ13μm tuaj yeem siv tau, thiab rau cov qauv ntim ntawm 10-100ml, Φ25μm tuaj yeem siv.

• Polyethersulfone (PES)

Nta: Hydrophilic lim membrane muaj cov yam ntxwv ntawm tus nqi siab, tsis tshua muaj extractables, zoo zog, tsis adsorb proteins thiab rho tawm, thiab tsis muaj kuab paug rau cov qauv.

Daim ntaub ntawv: Tsim los rau biochemistry, kuaj, tshuaj thiab tsis muaj tshuaj pom.

• Mixed cellulose esters (MCE)

Nta: Uniform pore loj, siab porosity, tsis muaj xov xwm tawm, nyias kev ntxhib los mos, tsis muaj zog, ceev ceev ceev, tsawg adsorption, tsis tshua muaj nqi thiab nqi, tab sis tsis resistant rau organic daws thiab muaj zog acid thiab alkali daws.

Daim ntawv thov: Lim cov tshuaj aqueous lossis sterilization ntawm cov khoom siv hluav taws xob kub-rhiab heev.

• Nylon Membrane (Nylon)

Nta: Kub ua haujlwm zoo, tuaj yeem tiv taus 121 ℃ saturated chav kub siab kom tsis muaj menyuam rau 30 feeb, tshuaj lom neeg ruaj khov, tuaj yeem tiv taus cov kua qaub, dilute alkali, cawv, esters, roj, hydrocarbons, halogenated hydrocarbons thiab organic oxidation ntau yam organic thiab inorganic. tshuaj sib xyaw.

Daim Ntawv Thov: Pom cov dej daws teeb meem thiab cov txheej txheem organic mobile.

• Polytetrafluoroethylene (PTFE)

Nta: Qhov dav tshaj plaws tshuaj sib raug zoo, muaj peev xwm tiv taus cov kuab tshuaj organic xws li DMSO, THF, DMF, methylene chloride, chloroform, thiab lwm yam.

Daim ntawv thov: Lim ntawm tag nrho cov organic tov thiab muaj zog acids thiab bases, tshwj xeeb tshaj yog muaj zog cov kuab tshuaj uas lwm cov lim membranes tsis tuaj yeem zam.

• Polyvinylidene fluoride daim nyias nyias (PVDF)

Nta: Daim nyias nyias muaj lub zog txhua yam, zoo tiv thaiv tshav kub thiab tshuaj lom neeg ruaj khov, thiab qis protein adsorption tus nqi;nws muaj zog tsis zoo electrostatic zog thiab hydrophobicity;Tab sis nws tsis tuaj yeem zam acetone, dichloromethane, chloroform, DMSO, thiab lwm yam.

Daim ntawv thov: Hydrophobic PVDF daim nyias nyias yog tsuas yog siv rau cov pa roj thiab chav filtration, thiab high-temperature kua pom.Hydrophilic PVDF membrane feem ntau yog siv rau kev kho kom tsis muaj menyuam ntawm cov ntaub so ntswg kab lis kev cai xov xwm thiab kev daws teeb meem, kev kub siab ua kua pom, thiab lwm yam.
