Nzira yekusarudza Siringe Sefa

Chinangwa chikuru chesefa chesirinji ndechekusefa zvinwiwa uye kubvisa zvidimbu, sediments, microorganisms, nezvimwewo. Zvinoshandiswa zvakanyanya mubiology, chemistry, sainzi yezvakatipoteredza, mushonga, nemishonga.Iyi sefa inofarirwa zvakanyanya nekuda kwayo yakanakisa kusefa maitiro, kureruka uye kushanda nesimba.Nekudaro, kusarudza iyo sirinji sefa haisi nyore uye inoda kunzwisisa hunhu hweakasiyana mafirita membrane uye zvimwe zvine chekuita nazvo.Ichi chinyorwa chichaongorora mashandisirwo emasefa etsono, hunhu hweakasiyana membrane zvinhu, uye maitiro ekuita sarudzo chaiyo.

• Hukuru hwepore hwesefa membrane

1) Sefa membrane ine pore saizi ye 0.45 μm: inoshandiswa kune yakajairwa mbozha nhanho kusefa uye inogona kusangana neyakajairwa chromatographic zvinodiwa.

2) Sefa membrane ine pore saizi ye 0.22μm: Inogona kubvisa zvakanyanyisa zvidimbu mumasampuli uye mobile phases pamwe nekubvisa tupukanana.

• Diameter ye filter membrane

Kazhinji, iyo inowanzo shandiswa sefa membrane madhayamita ndeye Φ13μm uye Φ25μm.Kune sampuli mavhoriyamu e0-10ml, Φ13μm inogona kushandiswa, uye yemuenzaniso mavhoriyamu e10-100ml, Φ25μm inogona kushandiswa.

• Polyethersulfone (PES)

Zvimiro: Hydrophilic filter membrane ine hunhu hwekuyerera kwehuwandu, yakaderera inotorwa, simba rakanaka, haishambadzi mapuroteni uye yakatorwa, uye haina kusvibiswa kune sampuli.

Zvishandiso: Yakagadzirirwa biochemistry, kuyedza, mishonga uye sterile filtration.

• Mixed cellulose esters (MCE)

Zvimiro: Uniform pore size, high porosity, hapana media media, kutetepa kwemavara, kushomeka kushoma, kukurumidza kusefa kukurumidza, kushoma adsorption, mutengo wakaderera uye mutengo, asi usingamiri kune organic mhinduro uye yakasimba acid uye alkali mhinduro.

Kushandisa: Kusefa kwezvinogadzirisa zvine aqueous kana sterilization yezvigadziriso zvinonzwa kupisa.

• Naironi membrane (Naironi)

Zvimiro: Yakanaka tembiricha kuramba, inogona kumira 121 ℃ yakazara mutsi inopisa kudzvanywa kwemaminetsi makumi matatu, yakanaka kemikari kugadzikana, inogona kutsungirira dilute acids, dilute alkali, alcohols, esters, mafuta, hydrocarbons, halogenated hydrocarbons uye organic oxidation Yakasiyana organic uye inorganic. makemikari.

Kushandisa: Kusefa kweaqueous mhinduro uye organic mobile phases.

• Polytetrafluoroethylene (PTFE)

Zvimiro: Iyo yakakura kwazvo kemikari inoenderana, inokwanisa kumira organic solvents seDMSO, THF, DMF, methylene chloride, chloroform, nezvimwe.

Kushandisa: Kusefa kwese organic solutions nemaasidhi akasimba nemabhesi, kunyanya masolvents akasimba ayo mamwe masefa membranes asingagoni kushivirira.

• Polyvinylidene fluoride membrane (PVDF)

Zvimiro: Iyo membrane ine simba rakawanda remagetsi, yakanaka kupisa kupisa uye kugadzikana kwemakemikari, uye yakaderera protein adsorption rate;ine simba rakasimba remagetsi emagetsi uye hydrophobicity;asi haigone kushivirira acetone, dichloromethane, chloroform, DMSO, nezvimwe.

Chishandiso: Hydrophobic PVDF membrane inonyanya kushandiswa gasi uye sefa yemhepo, uye yakakwirira-tembiricha yemvura kusefa.Hydrophilic PVDF membrane inonyanya kushandiswa kurapa kurapa kwetishu tsika midhiya uye mhinduro, yakakwirira-tembiricha yemvura kusefa, nezvimwe.
