ʻO ka membrane PTFE he kiʻiʻoniʻoni lahilahi, porous nui e hana ana me he membrane paʻa paʻa.ʻO kā lākou ʻano hydrophobic maoli e hoʻolilo i nā membrane PTFE i mea kūpono no nā noi e like me ke kānana ʻana i nā kinoea, aqueous aerosols, pale ʻana i nā ʻūhā ʻūhā, a i ʻole nā pahu fermentation sterile.ʻAʻole inert ka PTFE i nā mea hoʻoheheʻe kemika ikaika loa, nā ʻakika ikaika a me nā kumu a hiki ke hoʻohana ʻia no ka hoʻomaʻamaʻa ʻana i ka solvent a me ka hoʻomākaukau ʻana o ka HPLC.
Loaʻa nā membrane PTFE me ke kākoʻo ʻole ʻia a kākoʻo ʻia.ʻO nā membrane PTFE me kahi kākoʻo pūnaewele polypropylene laminated i kekahi ʻaoʻao e hāʻawi i nā hiʻohiʻona maikaʻi.Hoʻokomo ʻia nā palena kemika a me ka wela e ke kākoʻo.
ʻO kekahi o nā hiʻohiʻona koʻikoʻi i ka koho ʻana o ka membrane inā makemake ʻoe i kahi membrane he Hydrophobic a Hydrophilic paha.Maanei mākou e wehewehe ai i kēia mau huaʻōlelo, a me ka hāʻawi ʻana i kekahi mau hiʻohiʻona o nā mea membrane a me nā noi no nā ʻano ʻelua.ʻO ka hydrophilic ka manaʻo maoli "aloha wai."Hiki i nā membrane hydrophilic ke huki i ka wai, a ma ke kaʻina hana e hoʻokuke aku i nā molekala ʻē aʻe i mea e hiki ai i ka wai ke komo i ka membrane.Mālama kēia i nā mea haumia mai ka membrane e hiki ai ke noho maʻemaʻe a hana no ka manawa lōʻihi.Ma muli o kēia ʻano, ua kūpono nā membrane hydrophilic no nā noi olakino a me nā hoʻokolohua biological.ʻO ka Hydrophobic ma ka ʻaoʻao ʻē aʻe, ʻo ia hoʻi "makaʻu i ka wai."
Na kēia mau membrane e ālai i ka hele ʻana o ka wai a hoʻohana mau ʻia no nā noi e pili ana i ka hoʻokaʻawale ʻana o ka wai mai nā mea ʻē aʻe, e like me ka hoʻokuʻu ʻana i nā kinoea.Eia kahi papaʻaina kōkua e hoʻohālikelike i nā mea membrane a me nā hoʻohana maʻamau no nā waiwai hydrophilic a me hydrophobic:
