Kutamisa Ngoro pachitima

Muchiyedzo chechromatographic, sampu inoiswa pane chromatographic column kuti iongororwe mushure mekunge sampler abaiwa. Nekudaro, iyo yemukati musimboti wesampler uye chromatographic column yakatetepa. Kana paine zvimedu zvakakura mumuenzaniso, zvinogona kuita kuti mudziyo uvhare, Inoda kushandisa Syringe Sefa yekutanga sampu yekusefa kurapwa.

Vashandi vedu vehunyanzvi vanowanikwa kuburikidza nechat chat uye email kuti ikubatsire kusarudza pane yakanakisa membrane sefa kune zvaunoda. Titumire email, uye vamiriri vedu vanobatsira vatengi vanozopindura nekukasira-muzuva rimwe chete rebhizinesi kana nekukurumidza. Uye kana uchiri kuda rubatsiro kusarudza pachigadzirwa chakakodzera, tinokutumira sampuli kuti uone kuti iwe unogamuchira yakanakisa membrane sefa pane zvaunoda.

Kunyangwe Aijiren iine mitengo inoyevedza, yakatarisa ichiri pamhando. Iyo membrane zvinhu zvinopihwa nevanhu vane mukurumbira muindastiri, uye mune ISO9000 yakasimbiswa dhizaini maitiro, ichangoburwa yekugadzira tekinoroji inoshandiswa, uye kugadzirwa kunoitwa pasi peiyo yepamusoro-soro pasi peyakasimbiswa yakachena kamuri mamiriro kuti ave nechokwadi chemhando yepamusoro uye yakagadzikana zvigadzirwa. . Ese mafirita esirinji ane HPLC anosimbiswa.

Hydrophobic PTFE (Polytetrafluoroethylene) sirinji mafirita akakodzera gasi uye organic mhinduro, nekuita kwakanakisa kwemasamples anoora zvakanyanya. Zvinogoneka kune yakawedzera sampling renji uchishandisa hydrophobic PTFE mafirita kune yakakura makemikari kuramba kune hukasha zvinhu uye kudzikamisa tembiricha. Sefa yePTFE sirinji isarudzo yakanaka yekusefa uye de-gassing chromatography solvents.

Polyvinylidene difluoride (PVDF):? Yakagadzirirwa kusimba kwakanyanya, kunyungudutsa kwakanyanya, uye kusungirirwa kweprotein shoma, zvichiita kuti ive yakakodzera kusefa kwebiomedical, kusefa, uye kugadzirira sampuli yeHPLC. pH chiyero ~ 1-14.

Aijiren's syringe mafirita akavakwa kuti asangane nelab¡¯s kujekeswa uye sterilization zvinodiwa. Masefa edu anowanikwa muhukuru hwakasiyana uye membranes anogona kushandiswa zviri nyore kune ese asina mbereko...

Naizvozvo, zvinokurudzirwa kuti utarise zvakatemwa zvechigadzirwa kana kubata mutengesi kuti uwane ruzivo rwakakwana nezve sirinji mafirita auri kufunga nezve yako chaiyo application.
Iyo firimu yePES yakavharwa mugoko repolymer pasina kushandisa chero chinonamira. Imwe neimwe unit inogona kupa ETO kana Gamma radiation disinfection, uye kuona kuti hapana pyrogen.

Shandisa Aijiren CA sirinji sefa kuti ubvise zvinokanganisa zvinhu uye zvimedu zvakanaka kune yakayerwa pore saizi, nekudaro uchiwana yekuchenesa sampuli yekubvisa. Cellulose acetate (CA) mafirita esirinji akanakira kusefa matishu tsika midhiya uye kusefa masampula ebhayoloji anonzwa. Kuwedzera sirinji yekusefa nhanho pamberi pe chromatographic jekiseni haingobatsiri kuve nechokwadi chakanyatsoenderana uye chakavimbika mhedzisiro, inobatsirawo kuchengetedza chiridzwa uye kuwedzera hupenyu hwekoramu. Economical sarudzo Sirinji mafirita anowanikwa muhukuru hwakasiyana uye membrane mhando kuzadzisa zvinodiwa chero application.

Iyo hydrophobic PTFE membrane ine yakakura kuenderana kwemakemikari uye yakaderera kwazvo kunyungudika, uye parizvino ndiyo inonyanya kurwisa kemikari membrane pakati pesefa membranes. Aijiren's innovative dhizaini inobvumira iyo PTFE sefa kuti iwane chiyero chakakwana pakati pekuwedzera kweanoshanda kusefa nzvimbo uye kuderera kwemuenzaniso wekuchengetedza vhoriyamu. Iyo sefa inokwanisa kumirisana nepamusoro pemashandisirwo ekushanda, ichinyatso kudzivirira kubuda.

Izvo zvakakosha kuti uzive kuti chaiyo ruzivo rwehydrophobic PVDF membrane sefa mafirita, senge pore saizi, dhayamita, uye kusefa kugona, anogona kusiyana pakati pevagadziri uye mitsara yechigadzirwa.

Iyo naironi membrane yesirinji sefa inofanirwa kuenderana nemakemikari maitiro emuenzaniso. Iyo membrane yenylon inofanirwa kuenderana neyakasiyana-siyana-yakavakirwa mvura uye organic solvents. Iyo membrane inofanirwawo kuve nekupikisa kwakanyanya kune HPLC solvents uye makemikari. Iyo 0.45mm aperture inova nechokwadi chekuti une huwandu hwakaringana uye kuburikidza nekugadzira masampula nemazvo uye nekukurumidza.

PES (Polyethersulfone) sirinji sefa ndeye yakasikwa hydrophilic iyo inoita sarudzo yakanaka (inokurudzirwa zvakanyanya) yemhinduro dzine aqueous nedoro. Izvo hazvifanirwe kurapa iyo sefa membrane pamusoro neanonyorova vamiririri.

Polyethersulfone (PES):?Hydrophilic, yakagadzikana mupH yakaderera, ine mwero wakaderera wezvinotorwa, uye inoratidza yakaderera mapuroteni anosunga, zvichiita kuti zvikodzere kune akawanda aqueous uye organic zvinonyungudutsa. PES membranes inobvumira kuyerera kwemvura kwakakwira kupfuura PTFE. Tembiricha inodzivirira. pH range ~ 3-14 (dzimwe nguva inotorwa se1-14).

Mukuongorora kweHPLC, saizi yechromatographic column packing idiki uye inovharika zviri nyore nezvimedu zvinosvibisa. t. Mukuongorora kweHPLC neIC, masefa ejekiseni anogona kushandiswa kusefa maekisesaizi emhinduro, rinova danho rakakosha mumuenzaniso we pretreatment.

PTFE (polytetrafluoroethylene) kuita: yakakodzera kumvura system uye akasiyana organic solvents, inopikisa kune zvese zvinonyungudutsa, yakaderera solubility. Iine maitiro ekufema kwemhepo uye kusapindira kwemvura, mhepo yakakura yemhepo, yakakwirira particle retention rate, yakanaka yekudzivirira kupisa, kuramba kune yakasimba acids, alkalis, organic solvents uye oxidants, kuramba kuchembera, kusanamatira, kusapisa, kusapisa, uye biocompatibility. Zvigadzirwa zvayo zvine hukama zvinoshandiswa zvakanyanya mumakemikari, mishonga, kuchengetedza kwezvakatipoteredza, zvemagetsi, chikafu, simba uye mamwe minda.

Sterile filtration inogona kushandisa 0.2¦Ìm pore saizi, uye yedu isina kuchena kusefa chigadzirwa renji rinosanganisira 0.45 pore saizi. Kuti udzivise kusvibiswa kwemuenzaniso paunenge uchishandisa zvishandiso zvisina hutachiona, aya maaperture akakura anogona kushandiswa. Isu tinopa akatevedzana esterile kusefa zvigadzirwa kune akasiyana vhoriyamu maapplication.

Aijiren's syringe mafirita akavakwa kuti asangane nelab¡¯s kujekeswa uye sterilization zvinodiwa. Masefa edu anowanikwa muhukuru hwakasiyana uye membranes anogona kushandiswa zviri nyore kune ese asina mbereko...

Iyo MCE membrane inopa yakasarudzika kuchengetedza, kuteya zvimedu uye tupukanana tudiki se 0.22 μm muhukuru. Uku kusefa kwakanaka kunobatsira kuchengetedza zviridzwa zvekuongorora, HPLC masisitimu, uye zvimwe zvekushandisa lab kubva pakusvibiswa, kuchengetedza kuita kwavo kwakanyanya uye kuwedzera hupenyu hwavo.

Sefa yesirinji (kana kuti vhiri sefa) ishandiso imwe chete, membrane-yakavakirwa mudziyo unoshandiswa pakubvisa tsvina yemukati kubva kudiki (≤ 100 mL) yemvura samples. Yakasarudzwa zvichibva pane yaidiwa yekupedzisira application, inoraswa sirinji mafirita anowanzo shandiswa mumaLab ekusefa nekukurumidza uye nemazvo, kucheneswa kwezvinhu, kana kunyange sterilization.

Aijiren brand sirinji mafirita ndeye HPLC yakasimbiswa kuti ive nechokwadi chechokwadi uye chinowirirana mhedzisiro. Mvura, methanol, uye acetonitrile zvinoshandiswa pakuedza, uye HPLC inoshandiswa pakuona pa210 uye 254 nm wavelengths. Hapana inobata ultraviolet mwenje, iyo inogona kupa yakachena yekuongorora kumashure.

Polypropylene inowirirana neacetone, ethyl acetate, methanol, isobutanol, methanol uye methyl ethyl ketone. Polypropylene haienderani ne cyclohexane, ether, dichlorobenzene, pentane, methylene chloride uye trichlorobenzene. Zvinokurudzirwa kushandisa gasi, disinfectant kana autoclave kusvibisa zvigadzirwa zvakagadzirwa ne polypropylene. Iyo yakanyanya tembiricha yekushanda i135¡ãC.

Aijiren's PVDF sirinji sefa ine hydrophilicity uye yakanaka kuenderana kwemakemikari. Vanogona kuunza humbowo kutsvagiridzo yako uye kuve nechokwadi chepamusoro danho rekuita. Yedu mafirita akateedzana akagadzirwa nevakadzi Leur-lock inlet uye murume Leur-slip outlet. Pamusoro pezvo, aya mafirita ane zvirinani mechanical resistance uye anogona kumira tembiricha yakakwira.
