Momwe Mungasankhire Sefa ya Syringe

Momwe Mungasankhire Sefa ya Syringe

Cholinga chachikulu cha zosefera za syringe ndikusefa zamadzimadzi ndikuchotsa particles, sediments, microorganisms, etc. Amagwiritsidwa ntchito kwambiri mu biology, chemistry, science science, mankhwala, ndi mankhwala.Fyuluta iyi ndiyotchuka kwambiri chifukwa cha kusefera kwake, kusavuta komanso kuchita bwino.Komabe, kusankha sefa ya syringe yoyenera sikophweka ndipo kumafuna kumvetsetsa mawonekedwe a nembanemba zosiyanasiyana zosefera ndi zina zofananira.Nkhaniyi iwunika momwe zosefera za singano zimagwiritsidwira ntchito, mawonekedwe amitundu yosiyanasiyana ya membrane, komanso momwe angasankhire bwino.

• Kukula kwa pore kwa nembanemba ya fyuluta

1) Sefa nembanemba yokhala ndi pore kukula kwa 0.45 μm: yogwiritsidwa ntchito ngati kusefera pafupipafupi kwa gawo la mafoni ndipo imatha kukwaniritsa zofunikira zonse za chromatographic.

2) Sefa nembanemba yokhala ndi pore kukula kwa 0.22μm: Imatha kuchotsa tinthu tating'onoting'ono tating'onoting'ono mu zitsanzo ndi magawo am'manja komanso kuchotsa tizirombo.

• Diameter of filter membrane

Nthawi zambiri, mainchesi omwe amagwiritsidwa ntchito pafupipafupi ndi Φ13μm ndi Φ25μm.Kwa zitsanzo za 0-10ml, Φ13μm zingagwiritsidwe ntchito, ndi zitsanzo za 10-100ml, Φ25μm zingagwiritsidwe ntchito.

• Polyethersulfone (PES)

Mawonekedwe: Hydrophilic fyuluta nembanemba imakhala ndi mawonekedwe othamanga kwambiri, otsika otsika, mphamvu yabwino, samatsatsa mapuloteni ndi zowonjezera, ndipo alibe kuipitsa kwachitsanzo.

Ntchito: Zapangidwira biochemistry, kuyesa, mankhwala komanso kusefera kosabala.

• Mixed cellulose esters (MCE)

Zomwe Zilipo: Kukula kwa pore kofanana, porosity yayikulu, palibe kukhetsa kwa media, mawonekedwe ocheperako, kukana kutsika, kuthamanga kusefera mwachangu, kutsatsa pang'ono, mtengo wotsika komanso mtengo, koma osagonjetsedwa ndi mayankho a organic ndi mayankho amphamvu a asidi ndi alkali.

Kugwiritsa ntchito: Kusefa kwa madzi amadzimadzi kapena kuthirira kwa mankhwala omwe samva kutentha.

• Nembala ya nayiloni (nayiloni)

Mbali: Good kutentha kukana, akhoza kupirira 121 ℃ ano zimalimbikitsa nthunzi kutentha yolera yotseketsa yotseketsa kwa mphindi 30, wabwino mankhwala bata, kupirira zidulo dilute, kuchepetsa alkali, alcohols, esters, mafuta, ma hydrocarbons, halogenated hydrocarbon ndi organic makutidwe ndi okosijeni A zosiyanasiyana organic ndi inorganic. mankhwala.

Kugwiritsa Ntchito: Kusefera kwa mayankho amadzimadzi ndi magawo amtundu wa organic.

• Polytetrafluoroethylene (PTFE)

Mawonekedwe: Kulumikizana kwakukulu kwambiri kwamankhwala, kumatha kupirira zosungunulira organic monga DMSO, THF, DMF, methylene chloride, chloroform, etc.

Kugwiritsa ntchito: Kusefera kwa ma organic solutions ndi ma acid amphamvu ndi maziko, makamaka zosungunulira zamphamvu zomwe ma nembanemba ena amasefa sangathe kulekerera.

• Polyvinylidene fluoride membrane (PVDF)

Mawonekedwe: Nembanemba imakhala ndi mphamvu zamakina apamwamba, kukana kutentha kwabwino komanso kukhazikika kwamankhwala, komanso kutsika kwa protein adsorption;ali amphamvu zoipa electrostatic katundu ndi hydrophobicity;koma sangathe kulekerera acetone, dichloromethane, chloroform, DMSO, ndi zina zotero.

Ntchito: Hydrophobic PVDF nembanemba zimagwiritsa ntchito mpweya ndi nthunzi kusefera, ndi mkulu-kutentha madzi kusefera.Hydrophilic PVDF nembanemba zimagwiritsa ntchito wosabala mankhwala a minofu chikhalidwe TV ndi njira, mkulu-kutentha madzi kusefera, etc.
