Pehea e koho ai i kahi kānana Syringe

ʻO ke kumu nui o nā kānana syringe e kānana i nā wai a hoʻoneʻe i nā ʻāpana, sediments, microorganisms, a me nā mea ʻē aʻe.He mea kaulana kēia kānana no kona hopena kānana maikaʻi loa, ʻoluʻolu a me ka pono.Eia nō naʻe, ʻaʻole maʻalahi ke koho ʻana i ka kānana syringe kūpono a pono e hoʻomaopopo i nā ʻano o nā ʻano membrane filter a me nā mea pili ʻē aʻe.E ʻimi kēia ʻatikala i ka hoʻohana ʻana i nā kānana nila, nā ʻano o nā mea membrane like ʻole, a pehea e hana ai i ke koho kūpono.

• ʻO ka nui o ka pore o ka membrane kānana

1) Kānana membrane me ka nui o ka pore o 0.45 μm: hoʻohana ʻia no ka kānana maʻamau maʻamau o ka pae kelepona a hiki ke hoʻokō i nā koi chromatographic maʻamau.

2) kānana membrane me ka nui pore o 0.22μm: Hiki iā ia ke hoʻoneʻe i nā ʻāpana maikaʻi loa i nā laʻana a me nā pae kelepona a me ka wehe ʻana i nā microorganism.

• Anawaena o ka membrane kānana

ʻO ka maʻamau, ʻo nā anawaena membrane kānana maʻamau ʻo Φ13μm a me Φ25μm.No ka laʻana puke o 0-10ml, Φ13μm hiki ke hoʻohana, a no ka laʻana puke o 10-100ml, Φ25μm hiki ke hoʻohana.

• Polyethersulfone (PES)

Nā hiʻohiʻona: ʻO ka membrane kānana Hydrophilic nā hiʻohiʻona o ke kahe kahe kiʻekiʻe, nā haʻahaʻa haʻahaʻa, ikaika maikaʻi, ʻaʻole ia e hoʻopili i nā proteins a me nā extracts, a ʻaʻohe haumia i ka hāpana.

Nā noi: Hoʻolālā ʻia no ka biochemistry, hoʻāʻo, lāʻau lapaʻau a me ka kānana sterile.

• Ester cellulose hui ʻia (MCE)

Nā hiʻohiʻona: ʻO ka nui o ka pore kūlike, ka porosity kiʻekiʻe, ʻaʻohe hoʻoheheʻe media, ke ʻano lahilahi, ke kūpaʻa haʻahaʻa, ka wikiwiki kānana wikiwiki, ka liʻiliʻi adsorption, ke kumu kūʻai haʻahaʻa a me ke kumu kūʻai, akā ʻaʻole kūʻē i nā hopena organik a me nā waika ikaika a me nā hopena alkali.

Noi: Hoʻomaʻemaʻe i nā ʻano wai a i ʻole sterilization o nā mea hoʻomākaukau wela.

• ʻO ka membrane nylon (Nylon)

Nā hiʻohiʻona: ʻO ke kūpaʻa wela maikaʻi, hiki ke kū i ka 121 ℃ saturated steam hot pressure sterilization no 30 mau minuke, kūpaʻa kemika maikaʻi, hiki ke kū i nā waikawa dilute, dilute alkali, alcohols, esters, aila, hydrocarbons, halogenated hydrocarbons and organic oxidation ʻO nā ʻano mea like ʻole a me ka inorganic. pūhui.

Noi: Ka kānana ʻana i nā hāʻina wai a me nā ʻanuʻu kelepona.

• Polytetrafluoroethylene (PTFE)

Nā hiʻohiʻona: ʻO ka laulima nui loa, hiki ke kū i nā solvents organik e like me DMSO, THF, DMF, methylene chloride, chloroform, etc.

Noi: Ka kānana ʻana i nā mea hoʻoheheʻe kūlohelohe a me nā ʻakika ikaika a me nā kumu, ʻoi aku ka ikaika o nā mea hoʻoheheʻe ʻaʻole hiki ke ʻae ʻia e nā membrane kānana ʻē aʻe.

• ʻO ka polyvinylidene fluoride membrane (PVDF)

Nā hiʻohiʻona: ʻO ka membrane ka ikaika mechanical kiʻekiʻe, ke kūpaʻa wela maikaʻi a me ke kūpaʻa kemika, a me ka helu haʻahaʻa adsorption protein;loaʻa iā ia nā waiwai electrostatic maikaʻi ʻole a me ka hydrophobicity;akā ʻaʻole hiki iā ia ke ʻae i ka acetone, dichloromethane, chloroform, DMSO, etc.

Noi: Hoʻohana nui ʻia ka membrane PVDF Hydrophobic no ka holoi ʻana i ke kinoea a me ka mahu, a me ka kānana wai wela kiʻekiʻe.Hoʻohana nui ʻia ka membrane Hydrophilic PVDF no ka mālama sterile o ka media moʻomeheu a me nā hoʻonā, ka kānana wai wela kiʻekiʻe, etc.
