Mokhoa oa ho khetha Sefe ea syringe

Morero o ka sehloohong oa lihloela tsa syringe ke ho sefa maro le ho tlosa likaroloana, sediments, microorganisms, joalo-joalo. Li sebelisoa haholo ho baeloji, k'hemistri, saense ea tikoloho, meriana le meriana.Setlhopha sena se tumme haholo ka phello ea sona e ntle ea ho sefa, bonolo le bokhabane.Leha ho le joalo, ho khetha filthara e nepahetseng ea syringe ha ho bonolo ebile ho hloka ho utloisisa litšobotsi tsa li-membrane tse fapaneng tsa filthara le lintlha tse ling tse amanang le tsona.Sengoliloeng sena se tla hlahloba ts'ebeliso ea li-filters tsa nale, litšobotsi tsa lisebelisoa tse fapaneng tsa membrane, le mokhoa oa ho etsa khetho e nepahetseng.

• Boholo ba pore ea lera la sefe

1) Sefa membrane e nang le boholo ba pore ea 0.45 μm: e sebelisetsoang mohlala o tloaelehileng oa ho sefa mohato oa mohala 'me e ka finyella litlhoko tse akaretsang tsa chromatographic.

2) Filter membrane e nang le boholo ba pore ea 0.22μm: E ka tlosa likaroloana tse ntle haholo ka lisampole le mekhahlelo ea mobile hammoho le ho tlosa likokoana-hloko.

• Diameter ea lera la filthara

Ka kakaretso, li-diameter tse sebelisoang ka tloaelo tsa filthara ke Φ13μm le Φ25μm.Bakeng sa mehlala ea li-volumes tsa 0-10ml, Φ13μm e ka sebelisoa, 'me bakeng sa meqolo ea sampuli ea 10-100ml, Φ25μm e ka sebelisoa.

• Polyethersulfone (PES)

Likarolo: Hydrophilic filter membrane e na le litšobotsi tsa sekhahla sa phallo e phahameng, li-extractable tse tlase, matla a matle, ha e khahlise liprotheine le li-extracts, 'me ha e na tšilafalo ho sampole.

Likopo: E etselitsoe biochemistry, liteko, tlhatlhobo ea meriana le e hloekisitsoeng.

• Li-mixed cellulose esters (MCE)

Likarolo: Boholo bo sa tšoaneng ba pore, porosity e phahameng, ha ho na ho tšolloa ha mecha ea litaba, mokhoa o mosesaane, ho hanyetsa ho fokolang, lebelo la ho hloekisa ka potlako, ho ba le lipapatso tse fokolang, theko e tlaase le litšenyehelo, empa ha li hanyetsane le tharollo ea manyolo le litharollo tse matla tsa acid le alkali.

Kopo: Ho sefa litharollo tse nang le metsi a mangata kapa ho hloekisa litokiso tse sa utloeng mocheso.

• Lera la nylon (Nylon)

Likarolo: Ho hanyetsa mocheso o motle, ho ka mamella 121 ℃ saturated mouoane o chesang mocheso bakeng sa metsotso e 30, botsitso bo botle ba lik'hemik'hale, bo khona ho mamella acid e hlapollang, ho hlapolla alkali, alcohols, esters, oli, hydrocarbons, halogenated hydrocarbons le organic oxidation Mefuta e fapaneng ea organic le inorganic. metsoako.

Kopo: Ho hlophisoa ha litharollo tsa metsi le mekhahlelo ea mehala ea tlhaho.

• Polytetrafluoroethylene (PTFE)

Likarolo: Khokahano e pharalletseng ea lik'hemik'hale, e khona ho mamella li-solvents tse kang DMSO, THF, DMF, methylene chloride, chloroform, joalo-joalo.

Kopo: Ho hlophisoa ha litharollo tsohle tsa manyolo le li-acid tse matla le li-bases, haholo-holo li-solvents tse matla tseo lisele tse ling li ke keng tsa li mamella.

• Polyvinylidene fluoride membrane (PVDF)

Likarolo: Lera le na le matla a phahameng a mochine, ho hanyetsa mocheso o motle le botsitso ba lik'hemik'hale, le tekanyo e tlaase ea protheine ea adsorption;e na le thepa e matla ea electrostatic le hydrophobicity;empa ha e khone ho mamella acetone, dichloromethane, chloroform, DMSO, joalo-joalo.

Kopo: Hydrophobic PVDF membrane e sebelisoa haholo-holo bakeng sa ho hloekisa ka khase le mouoane, le ho hloekisa metsi a mocheso o phahameng.Hydrophilic PVDF membrane e sebelisoa haholo bakeng sa kalafo e sa hloekang ea media media le litharollo, ho tlhotla metsi a mocheso o phahameng, jj.
