Isihlungi se-syringe sibuye sabizwa ngokuthi isihlungi esichithiwe sesirinji. Kuyisihlungi esisheshayo, esilula, nesinokwethenjelwa kumasampula amancane. Ama-laboraries asebenzisa njengengxenye ejwayelekile yokuhamba komsebenzi wabo. Kusebenza njengesihlungi esiyinhloko sokulungiselela amasampula. Ihlunga futhi inezinsimbi zelebhu uketshezi lwemvelo, amasiko abezindaba, kanye nezithasiselo. Isebenza ngama-syringes alahlwayo.

Izihlungi zesirinji zibalulekile ekuhlunga. Babulala futhi bahlunga amanzi nama-solvents ezi-organic (njenge-HPLC, UHPLC). Ngakho-ke kufanele sikhethe kanjani kusuka kuhlu lwamasayizi wokuhlunga nezinhlobo ze-membrane zokuhlunga? Ukufunda le ndatshana kuzocacisa ukungabaza kwakho.

Ububanzi be-Diameter

Izihlungi zesirinji zinosayizi we-4 mm, 13-15 mm, 25-28 mm, 33 mm, no-50 mm. Kusetshenziswa i-Chromatographic Sand Filtration13 mmkanye nosayizi abangama-25 mm njengezinga.

Ukukhetha usayizi wokuhlunga olungile, kufanele silandele lo mthetho: Ivolumu likhuphuka njengoba isihlungi senyuka sikhulu. Ukusika ukulahleka kwesampula futhi kunciphise ukugcwala kwe-membrane, khetha ububanzi bokuhlunga okususelwa kwithayimu yesampula.

Izihlungi zesirinji zamadayimitha ahlukene.

4 mm: Kunconyelwe i-0.05 ml - 1 ml ye-filtrate

I-13-15 mm: Kunconyelwe i-1 ml - 10 ml ye-filtrate

25-28 mm: Kunconyelwe i-10 mL - 50 ml ye-filtrate

33 mm: Kunconyelwe i-10 mL - 100 ml ye-filtrate

I-50 mm: Kunconyelwe i-100 ml - 500 ml ye-filtrate

Le khasi25 mm isivalo se-syringeInephuzu lentengo eliphakeme kunesihlungi se-13 mm. Isihlungi se-Syringe esingu-25 mm sinendawo enkulu ye-filltration futhi ingaphatha amavolumu wesampula amaningi. Isihlungi se-Syringe esiyi-13 mm sishibhile. Ilungele ukucubungula amasampula amancane.

Osayizi be-pore

Ubukhulu be-pore of the membrane yokuhlunga buye buyinto eyinhloko ekukhetheni isihlungi se-syripha. Ubukhulu obuphambili boMnxawu Wokuhlunga bangu-0.1 μm, 0.20 kuya ku-0.22 μm, 0.45 μm, 0.8 μm, no-100 μm. Amasayizi we-Pore of 0.22 μm kanye ne-0.45 μm alawule izinhlelo ze-HPLC ne-GC.

Izimo zokusebenzisa izihlungi zesirinji ezinosayizi ohlukile we-pore.

Le khasiI-0.22 μm isihlunga sesirinjikuvame ukusetshenziselwa ukugcwala inzalo. Usayizi we-0.22 μm pore ubeka ama-bacterium amaningi nama-microorganisms ngokuphelele. Isivivinyo senzelwe ukucubungula amasampula. Kudinga imvelo oyinyumba. Usebenzisa isihlungi se-syringe ye-memringe engu-0,22 μm uyisinqumo esihle kakhulu. Lokhu kuyiqiniso ngokwenza izidakamizwa, imikhiqizo yemvelo, kanye nezixazululo zomjovo. Kuyiqiniso futhi ngokwenza imidiya yesiko. Ungayisebenzisa futhi ukususa izinhlayiya ezinhle, isiko leseli, nokuningi.

Le khasiI-0.45 μm isihlunga sesirinjiKhipha izinhlayiya kusuka ku-ketshezi ngokunemba. Kungasusa izinhlayiya ezinkulu. Kuhle ngokuhlunga kwama-coarse. Abaphenyi badinga lokhu ngemisebenzi. Bayisebenzisa kumasampula entula enhlalo, amanzi angcolile, nokudla okuthile. Isusa izinhlayiya ezinkulu kusuka kwisampula ngokunemba. Ingakwazi ukuhlunga amasampula ngaphambi kokuhlaziywa. Lokhu kususa udaba olumisiwe ukugwema ukulimaza i-chromat.

Ukucatshangelwa kwevolumu

Amadayimane ahlukene nosayizi we-pore banemiphumela ehlukile yokuhlunga. Umthelela onembile kakhulu yijubane lokuhlunga kanye nevolumu yokugcinwa kolwelwesi lokuhlunga.

Ijubane lokuhlunga

Ngoba usayizi we-pore unendawo enkulu ye-fieltration, kuzoba nezinga lokugeleza okukhulu kwinqubo yokucindezela isirinji. Izihlungi ezisikini ezincane ezincane zinendawo encane ye-filltration, ngakho-ke izinga lokugeleza lihamba kancane kunaleso sokuhlunga okukhulu kwesirinji. Ukuhlunga okusikwenzile okulingana okuncane kulungele ukuhlunga amanani amancane amasampula noma izikhathi lapho izinga lokugeleza lingadingeki.

Umthamo wokugcinwa kabusha we-membrane yokuhlunga.

Ukuhlunga okusikwa okuncane okunezinhlamvu ezincane kunamavolumu ancanyana okugcina kunokuhlunga okukhulu kwesirinji. Amavolumu wokugcina amancane asho ukuthi isampula elincane ligcinwa ku-membrane yokuhlunga kanye ne-syringe yezindlu ngesikhathi sokuhlunga isampula, esinganciphisa ngokuphumelelayo ukulahlekelwa okwesampula futhi kufanelekile.

Zombili izihlungi ezinobukhulu obukhulu kanye nobukhulu zinezinzuzo zazo. Lapho ukhetha izihlungi, izivivinyo kufanele zikhethe usayizi wokuhlunga oqondile ngokwezidingo zemishini yokuhlola kanye namasampula angcolile.
