Lub syringe lim yog ib qho me me, tus kheej - muaj, thiab cov khoom siv tsis muaj kuab paug pom, feem ntau ntsia nruab nrab ntawm lub syringe chim thiab rab koob. Nws yog siv rau kev ua kom huv sai thiab ua tau zoo thiab ua kom tsis muaj menyuam ntawm cov khoom me me - cov qauv ua kua. Nws yog ib qho khoom siv tseem ceeb hauv cov chaw soj nstuam, tshuaj, biotechnology, thiab lwm yam kev lag luam xws li kev npaj ua qauv, chromatographic tsom xam, thiab kev lim dej kom tsis muaj menyuam.
Cov ntaub ntawv yooj yim
Lub syringe lim yog ib qho me me filtration chav tsev uas sib xyaw ua ke cov khoom siv lim dej thiab cov vaj tsev yas (feem ntau yog ua los ntawm polypropylene). Nws tus qauv interface (feem ntau yog Luer haum) ruaj ntseg txuas mus rau ntau qhov ntau thiab tsawg syringe (piv txwv li, 1mL, 5mL, 10mL, 20mL, 50mL).
Nws cov qauv tsim muaj xws li:
- Inlet:Txuas rau lub syringe chim.
- Prefilter Txheej (Yeem):Qee cov qauv muaj xws li txheej iav fiber ntau lossis polypropylene fiber ntau saum lub ntsiab membrane. Qhov no prefilter ntxiab loj dua, tiv thaiv lub downstream precision membrane los ntawm qhov ntxov ntxov clogging thiab txuas nws lub neej kev pab cuam.
- Filtration Membrane:Cov ntsiab lus tseem ceeb, txiav txim siab pom qhov tseeb thiab tshuaj lom neeg sib raug zoo. Muaj nyob rau hauv ntau yam ntaub ntawv thiab pore qhov ntau thiab tsawg.
- Kev them nyiaj yug txheej:Nyob rau hauv qab daim nyias nyias, feem ntau yog ib tug ntxeem tau polypropylene los yog polyethylene phaj los yog mesh. Nws txhawb nqa daim nyias nyias los tiv thaiv kev tawg hauv qab siab.
- Qhov hluav taws xob:Qhov chaw tawm mus rau cov kua lim dej, uas tuaj yeem coj mus rau hauv cov qauv vial, chromatography vial, lossis lwm yam khoom siv.
Cov yam ntxwv tseem ceeb muaj xws li:
- Compact Size & Yooj Yim:Me me, yooj yim rau kev khiav lag luam, yuav tsum tsis muaj cov cuab yeej siv, thiab yog qhov zoo tagnrho rau kev ua cov microliter rau milliliter cov qauv ntim.
- Ceev & Ua tau zoo:Los ntawm txhais tes siab los yog siv lub syringe twj tso kua mis enables ceev pom.
- High Cleanliness & Sterility Assurance:Tsim los rau kev siv ib zaug thiab muaj nyob rau hauv pre-sterilized (feem ntau gamma- irradiated) ntim, tiv thaiv tus ntoo khaub lig- kis kab mob thiab ua kom cov qauv tsis muaj menyuam (thaum siv cov qauv tsis muaj menyuam).

Txoj Cai Ua Haujlwm
Lub hauv paus ntsiab lus ua hauj lwm ntawm lub syringe lim yog feem ntau raws lisieving (mechanical tuav), muaj peev xwm pab tau los ntawm adsorption (nyob ntawm cov khoom siv membrane).
Siab Tsav:Tus neeg siv rub cov kua los lim rau hauv ib lub syringe, tshem cov koob, thiab ruaj ntseg txuas cov syringe taub rau lub lim inlet. Pushing lub syringe plunger siv lub siab zoo rau cov kua. Qhov no yog qhov sib txawv tseem ceeb ntawm cov ntxaij lim dej uas tso siab rau lub ntiajteb txawj nqus lossis lub tshuab nqus tsev (xws li lub tshuab nqus tsev pom).
Stepwise Retention:
- Prefiltration (yog tias muaj):Cov kua ua ntej dhau los ntawm txheej prefilter. Cov txheej txheem qhib fiber ntau ntawm cov txheej txheem no cuam tshuam cov khoom loj dua, flocs, lossis qee cov khoom siv colloidal, ua cov lim ntxhib thiab tiv thaiv cov kauj ruam.
- Precision Lim:Cov kua ces mus txog qhov tseem ceeb filtration membrane. Qhov no daim nyias nyias muaj ib tug meej, uniform ntxeem tau qauv. Raws li cov kua dej tau tsav los ntawm lub siab, cov khoom, cov kab mob (piv txwv li, kab mob, pwm spores), los yog macromolecules loj dua li daim nyias nyias qhov nominal pore loj yog lub cev khaws cia rau ntawm daim nyias nyias los yog hauv nws qhov pores.
- Sieving & Adsorption:Cov khoom nyob ze lossis me me dua li qhov pore loj tuaj yeem khaws cia ntxiv los ntawm cov txheej txheem adsorption (xws li, kev sib cuam tshuam hydrophobic, electrostatic kev sib cuam tshuam) los ntawm daim nyias nyias. Piv txwv li, hydrophilic nylon daim nyias nyias tuaj yeem nqus tau qee cov proteins.
Qauv Sau:Cov kua purified, clarified hla dhau los ntawm kev txhawb nqa txheej hauv qab daim nyias nyias thiab tawm ntawm qhov hluav taws xob. Nws tuaj yeem raug sau ncaj qha rau hauv qhov chaw txais khoom huv, npaj rau kev tshuaj xyuas tom ntej lossis ua tiav.
Lub hauv paus ntawm cov txheej txheem yogmembrane sieving tsav los ntawm zoo siab, ua kom pom kev ua tau zoo thiab kev sib cais ntawm cov hom phiaj zoo.
