Sereng filtèse yon zouti esansyèl nan anviwònman laboratwa a, espesyalman pou preparasyon echantiyon nan chimi analyse. Yo fèt yo retire patikil ak kontaminan soti nan likid anvan analiz, asire echantiyon pite ak entegrite. Nan divès opsyon ki disponib, 0.45 µm ak 0.22 µm filtè sereng yo se de nan kalite ki pi souvan itilize yo. Konprann diferans ki genyen ant filtè sa yo, aplikasyon yo, ak ki jan yo chwazi filtre nan dwa pou bezwen espesifik ou se esansyèl nan reyalize rezilta egzat ak serye.

Kesyon yo poze souvan sou filtè sereng, asire w ke ou tcheke deyò atik sa a enfòmatif: Sijè a nan "sereng filtre" 50 kesyon yo poze souvan

Sereng filtè konpoze de yon filtre manbràn antoure nan yon lojman plastik oswa vè ki efektivman filtè ti kantite likid. Gwosè a pò nan filtre a detèmine gwosè a nan patikil ki ka retire li. De gwosè pò ki pi komen yo se 0.45 µm ak 0.22 µm, chak nan yo ki gen diferan itilizasyon depann sou kondisyon analyse.

0.45 µm sereng filtè

Aplikasyon:

0.45 µm sereng filtèyo tipikman itilize pou filtraj jeneral ak retire patikil. Yo efikas nan retire pi gwo patikil epi yo souvan itilize nan aplikasyon sa yo:

Prefiltrasyon: 0.45 µm filtè yo souvan itilize kòm prefilters pwoteje plis sansib instrumentation en (tankou HPLC oswa sistèm GC) soti nan obstrue ak pi gwo patikil.

Klarifikasyon: filtè sa yo apwopriye pou klarifye solisyon yo, espesyalman nan pwosedi laboratwa woutin kote kontaminasyon microbes se pa yon gwo enkyetid.

Filtrasyon faz mobil: Nan aplikasyon kwomatografi, yo itilize 0.45 µm filtè pou filtre faz mobil pou anpeche kontaminasyon kolòn.

Limit:

Pandan ke filtè 0.45 µm yo lajman itilize yo, yo ka pa apwopriye pou aplikasyon pou ki mande pou esterilizasyon oswa retire nan pi piti mikwo -òganis. Yo ka efektivman filtre soti patikil pi gwo pase 0.45 µm, men yo ka pèmèt pi piti bakteri yo pase nan, ki mennen ale nan kontaminasyon nan eksperyans sansib.

0.22 µm filtè sereng

Aplikasyon:

0.22 µm filtè serengyo souvan refere yo kòm filtè klas esterilize. Yo fèt pou retire bakteri ak lòt mikwo -òganis nan solisyon yo, sa ki fè yo apwopriye pou aplikasyon sa yo:

Esterilizasyon: filtè sa yo souvan itilize nan aplikasyon mikrobyolojik pou esterilize medya kilti, tanpon, ak lòt solisyon ki egzije yon anviwònman esteril.

Fòmilasyon famasetik: Nan endistri pharmaceutique a, yo itilize 0.22 µm filtè pou asire solisyon injectable yo gratis nan kontaminasyon microbes.

Biyoteknoloji: Yo esansyèl nan pwosesis biotechnologie kote entegrite echantiyon byolojik yo dwe konsève, tankou nan aplikasyon pou kilti selil yo.

Limit:

Pandan ke 0.22 µm filtè yo efikas nan retire bakteri yo, yo ka pa nesesè pou tout aplikasyon yo. Pou filtraj woutin kote kontaminasyon microbes se pa yon enkyetid, lè l sèvi avèk yon filtre 0.22 µm ka yon depans nesesè.

Ki jan yo chwazi filtè a sereng dwat

Chwazi filtre nan sereng dwa depann sou plizyè faktè, ki gen ladan nati a nan echantiyon ou a, nivo a nan filtraj yo mande yo, ak aplikasyon an gen entansyon. Men kèk konsiderasyon pou ede ou fè bon chwa a:

Detèmine objektif la: Si aplikasyon ou an egzije pou esterilizasyon oswa retire bakteri, chwazi yon filtre sereng 0.22 µm. Pou bezwen filtraj jeneral, tankou klarifye yon solisyon oswa pwoteje yon enstriman, yon filtre 0.45 µm ka ase.

Konsidere karakteristik echantiyon: Evalye pwopriyete yo nan echantiyon an ke yo te filtre. Pou egzanp, si echantiyon an gen pi gwo patikil, yon filtre 0.45 µm ka pi efikas. Kontrèman, si echantiyon an se sansib a kontaminasyon microbes, se yon filtre 0.22 µm rekòmande.

Evalye pri ak bidjè: Konsidere bidjè laboratwa ou a. Pandan ke 0.22 µm filtè yo jeneralman pi chè, yo ka nesesè pou aplikasyon espesifik. Pri balans ak enpòtans ki genyen nan entegrite echantiyon ak presizyon.

Konsilte direktiv manifakti: Toujou refere a espesifikasyon manifakti a ak rekòmandasyon pou filtè a sereng espesifik ou ap konsidere. Yo souvan bay bonjan enfòmasyon sou aplikasyon yo gen entansyon ak limit nan pwodwi yo.

Fè Metòd Validasyon: Si ou se toutafè si ki filtre yo itilize, konsidere fè yon eksperyans validasyon metòd yo konpare pèfòmans nan de kalite yo filtre nan aplikasyon espesifik ou. Sa ka ede w detèmine ki filtre bay pi bon rezilta yo.

Konprann diferans ki genyen ant de kalite filtre sa yo, aplikasyon yo, ak ki jan yo chwazi filtè a dwa pou bezwen espesifik ou se esansyèl nan akonplisman rezilta egzat ak repwodwi nan yon anviwònman laboratwa. Pa konsidere objektif la nan filtraj, karakteristik echantiyon, pri, ak direktiv manifakti, ou ka pran yon desizyon enfòme ki pral amelyore efikasite a ak efikasite nan pwosesis analyse ou.
