13mm 0.22 Sefa yeSirinji isina kubereka

Nekuda kweiyo yakakwira hydrophobicity yePVDF membrane, inoda kunyikwa mune yakakodzera mhinduro senge ethanol isati yashandiswa kuzadzisa chinangwa chekuita uye kuita kuti membrane ive nyore kusunga mapuroteni. Ichi chigadzirwa chinowirirana nedhayi dzakawanda, dzakadai sePonceau-S tsvuku, Coomassie brilliantblue, Sypro ruby, Transillumination, Toluidine blue, CPTS, Colloidal gold, India inkAmido nhema. Pakati pavo, mushure mekucheka nedhayi dzakadai sePonceau neCPTS, madhayi anogona kushambidzwa uye iyo firimu inogona kushandiswa pakuwedzera kuongororwa; nepo madhayi akadai seCoomassie Brilliant Blue, India inki, uye amide dema asingadzokerike, firimu harigone kushandiswa mushure mekudhaya. Kuti uwedzere kuongorora.

Pakushandisa maventi, sefa iyi sirinji inogona kudzivirira mwando kupfuura. Inoshandiswa pH renji: 1-14. PTFE inogona kuiswa kune: kusefa organic zvinonyungudutsa zvine kusimba kwemakemikari, kusefa yakasimba asidhi zvinonyungudutsa, kusefa alkali zvinonyungudutsa, zvinofambirana negaseous samples, uye inokwanisa kubata mvura inodziya yakanyanya./p>

PTFE: yakanakira kusefa kwegasi kana organic solvent-based samples uye zvinhu zvinoparadza zvakanyanya. Hydrophobic saka inopa makemikari kuramba kune hukasha midhiya uye yakanakisa tembiricha kugadzikana inobvumira yakawedzera sampling renji. Kana ikashandiswa neaqueous samples, membrane inowanzoda pre-wetting (kazhinji nekushandisa doro shoma). Inogona zvakare kushandiswa kudzivirira mwando kupfuura nepamhepo. pH chiyero ~ 1-14.

Sirinji sefa yakapihwa naAijiren ine cellulose acetate kana PES sefa membrane. A sterile membrane ine pore size ye 0.2um chinhu chakanakira kubereka nekusefa, nepo pore size ye 0.45¦Ìm inogona kushandiswa kujekesa. Iyo sterile tsono sefa inocheneswa negamma radiation, iyo inodzivirira muchetura wasara unokonzerwa nedzimwe nzira dzesterilization.

Sirinji mafirita anosanganisira imba yepurasitiki ine membrane sefa kune imwe magumo uye yevakadzi luer lock kana luer slip connection kune rimwe divi. Iyo sefa membrane inowanzogadzirwa nezvinhu zvakaita senylon, polyethersulfone (PES), polytetrafluoroethylene (PTFE), kana cellulose acetate.

Aijiren Tech Aijiren Syringe Mafirita ndiwo akadzama emhando isina-yakaora inoraswa sirinji mafirita ekuvimbika kugadzirira sampuli. Reproducible membrane mhando uye otomatiki ekugadzira maitiro anovimbisa kuti zvikamu zvinobviswa kubva kune yega yega sampu, kuwedzera analytical column hupenyu uye kuderedza jekiseni chiteshi kana kukuvara kwevharuvhu.

Yakasarudzwa PES sirinji mafirita inopa yekuchenesa sampuli yekubvisa nekubvisa zvinhu zvinokanganisa uye zvimedu zvakanaka kusvika pachiyero chepore. Kuita sirinji yekusefa nhanho pamberi pechromatographic jekiseni kunobatsira kuve nechokwadi chakanyatsoenderana uye chakavimbika mhedzisiro, uye inobatsira kuchengetedza zviridzwa zvakapfava uye kuwedzera hupenyu hwekoramu.

Shandisa sefa inoraswa uye sirinji inoraswa kusefa uye kufirisa, tanga wasveta mhinduro kuti isefirwe mujekiseni, wobva wadzvanya mhinduro mumudziyo usina mbereko uri pasi pesefa (iyo ine sefa membrane ine pore saizi ye0.22 microns), Izvi zvinoitwa. Kana huwandu hwekugadzirisa hunofanira kusefa hwakakura, unogona kutenga mudziyo wekusefa nepombi.

Aya mafirita esirinji anowana mashandisirwo munzvimbo dzakasiyana siyana semishonga, biotechnology, kuongororwa kwezvakatipoteredza, chikafu uye chinwiwa kuyedzwa, uye marabhoritari ekutsvagisa uko kunofanirwa kusefa chaiko kuti uve nechokwadi chekuchena uye kuvimbika.

Paunenge uchishandisa mavhaira, mafirita aya sirinji anogona kudzivirira hunyoro kuti husapfuure. Inoshandiswa pH renji: 1-14. PTFE inogona kuiswa kune: kusefa organic zvinonyungudutsa zvine simba kemikemikari corrosiveness, kusefa yakasimba asidhi zvinonyungudutsa, kusefa alkali zvinonyungudutsa, zvinoenderana negaseous samples, uye inokwanisa kubata yakanyanya-tembiricha zvinwiwa.

Disposable sirinji mafirita maturusi akagadzirirwa kuti ape nekukurumidza uye nekuita kusefa, premium mhando uye hupfumi. Iyo membrane inogona kunge iri PTEF, PVDF, PES, Nylon, MES, PP, CA, uye inogona kukodzera mamiriro akasiyana.

Mabhenefiti ako kana uchishandisa Aijiren sirinji mafirita£ºMhando dzakasiyana dze membrane kusangana nezvakawanda zvekusefa zvinodiwa. Yakaderera yemukati yeanokwanisa kutorwa. Kurumidza kuyerera geometry kuitira nyore kusefa. Yakaderera-kusimudza vhoriyamu yekunyanyisa kusefa kupora. HPLC yakasimbiswa
Yedu Syringe Filters ndeyemhando yepamusoro, yakanyatsorongedzwa uye inotengeswa nemutengo wakanaka wemakwikwi. Iwo anowanikwa mune mazhinji ehukuru membrane zvinhu zvinosanganisira Nylon, PTFE, PES, MCE, PVDF, CA, PP, uye GF izvo zvinopihwa mu13mm, 25mm mafomati mumhandara polypropylene housings.

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.

Kuti usefa zvimedu nenzira kwayo, unofanirwa kutsvaga saizi yakakodzera sefa. Iwe unofanirwa kusarudza dhayamita yesefa zvakanyatsonaka. Kazhinji vane saizi 13mm, 25mm uye 30mm. Imwe neimwe yeiyi ine kugona kwakasiyana kubata zvimedu. Zvinoenderana nesaizi yemuenzaniso, unogona kusarudza yakakodzera sefa dhayamita. Semuenzaniso, dhayamita ye13 mm inogona kushandiswa kune 1-10 ml samples. Saizvozvo, 25 mm PVDF sirinji mafirita anogona kushandiswa sampuli mavhoriyamu e10-100 ml. Kuchengetwa kwavo kuri pasi pe100 ml.

Iyo mhete yekusimbisa inogona kupa simba rakakura kune goko kudzivirira kuvuza uye kuputika (30mm chigadzirwa kudzvanywa kwakayerwa pa120 psi). Iyo goko rakagadzirwa ne-solvent-resistant, yakaderera-kubvisa polypropylene resin, yakanyatso kusarudzwa kuti ienderane neyakajairwa HPLC sampuro matrices. Mhinduro yacho inogona kusefa pane tembiricha inosvika 100¡ãC, iri nyore uye iri nyore kushandisa.

Syringe sefa mudziyo unoraswa unoshandiswa murabhoritari kusefa mavhoriyamu madiki emasampuli emvura. Inowanzo shandiswa kubvisa tunhu tudikidiki uye tupukanana kubva kune mhinduro isati yaongororwa kana kudzivirira inonzwisisika zviridzwa kubva mukusvibiswa.

Polypropylene (PP) inokurudzirwa kune imwe nguva kushandiswa chete neiyo yakaderera mhute kutapurirana. Polypropylene ipurasitiki yakasimba inopenya. Patembiricha yekamuri, polypropylene inoratidza yakanakisa makemikari kuramba kune acid, madoro, uye mabhesi. Polypropylene inowirirana neacetone, ethyl acetate, methanol, isobutyl doro, methanol, uye methyl ethyl ketone. Polypropylene haienderani ne cyclohexane, ethers, dichlorobenzene, pentanes, methylene chloride, uye trichlorobenzene.

Nylon membrane ine simba rakasimba remagetsi, kugadzikana kwemakemikari, inogona kushivirirwa neakawanda organic solvents, yakanyanya kuderera mune inotorwa, yakanaka yekudziya kugadzikana (kusvika ku50¡ãC), yakasikwa hydrophilic uye yakawanda yemvura mhinduro sefa maitiro. Iyo inowanzo shandiswa kune yakajairwa organic solvent HPLC mobile phase kusefa.

Mukuongorora kweHPLC, saizi yechromatographic column packing idiki uye zviri nyore kuvharwa nekusachena zvimedu. Naizvozvo, sampuli uye zvinonyungudutsa zvinoda kusefa pachine nguva kuti zvibvise zvinosvibisa uye kudzivirira chiridzwa. Ion chromatography, iyo inowanzo shandiswa mukuongorora kwezvakatipoteredza, inodawo kuti pasave nezvinosvibisa zvisingaunzwa mumuenzaniso wekutanga kurapwa.

Polypropylene chinhu chinowanzo shandiswa kune sirinji sefa dzimba nekuda kwekuenderana kwayo kemikari, yakaderera inotorwa, uye inopokana neyakasiyana-siyana yezvinonyungudutsa. PP dzimba dzinopa rutsigiro rwechimiro kune teh filter membrane uye kubatsira kuchengetedza kutendeseka kwayo panguva yekusefa.

Aijiren inoraswa sirinji sefa zvishandiso zvakagadzirirwa kupa nekukurumidza uye nekuita kusefa kweaqueous uye organic mhinduro kubva kudiki mavhoriyamu anosvika zana mL. Sirinji mafirita anosanganisa premium ...<250mL, to avoid setting ups of Buchner filters or similar.

Mafirita sirinji masefa anoshandirwa nejekiseni kuti ajekese mvura ine mvura (column eluate, tissue culture additives, HPLC samples, etc.<3um. 0.45 um membranes are typically used for general filtration and particle removal while 0.2/0.22um membranes, or sterilizing-grade membranes, are most commonly used for solution sterilization (bacteria removal).
