Hydrophilic filters can be wetted with virtually any liquid, and are the preferred filters for aqueous solutions, as appropriate by compatibility. Once wetted, hydrophilic filters do not allow the free passage of gases until the applied pressure exceeds the bubble point and the liquid is expelled from the pores of the membrane.
PTFE (Polytetrafluoroethylene-Hydrophobic) Hydrophobic • Gases or aggressive organic solvents • Highly acidic or basic samples and solvents • Can be made hydrophilic by wetting the membrane with alcohol and then flushing with deionized water. PTFE-L ü

Hydrophobic membrane filters are necessary for applications where the membrane is used to retain liquid water while allowing gases to pass through. Hydrophobic PCTE membranes typically have insufficient water entry pressures for these applications and will allow liquid water to
Nylon (NY) Membrane Information Nylon has inherent hydrophilic characteristics and works well for filtration of many aqueous and mixed-organic samples. For applications that require low protein or non-specific binding characteristics, Phenomenex recommends Phenex-RC (Regenerated Cellulose) filters.
2019/7/9 · The surface filter membrane is a hydrophobic PTFE membrane with no support. It can be used under extreme chemical or temperature conditions (up to 260°C) that other membranes cannot withstand. Hydrophobic PTFE membrane filter can be used for atmospheric filtration detection, usually only for air filtration.
PTFE is an inherently hydrophobic membrane excellent for filtration of organic-based, highly acidic or basic samples and solvents. Widely used in chromatography, it is especially well suited for the clarification of non-aqueous samples.
Hydrophilic PTFE membrane is optimized for low drug and protein binding with excellent throughput in typical aqueous and solvent sample preparation. High sample recoveries and low extractables provide for optimum analysis by HPLC and LC/MS/MS. The membrane is suitable for applications including natural product screening, aqueous solubility testing
This 13 mm syringe filter with a Hydrophilic PTFE membrane, for non-sterile filtration, has a 0.2 µm pore size used in clarification of aqueous & mild organic solutions for ion chromatography. Disposable syringe-operated filter units certified for ion chromatography sample
These hydrophilic, extremely low extractable/protein binding, PVDF membrane filters provide high flow rates and throughputs for aggressive, solvent-based mobile phase applications, biological sterilization/clarification, and HPLC/analytical sample preparation.
Hydrophilic PTFE membrane pore size is 0.22μm, 0.45μm and chemical compatibilities are superior to aqueous, organic solvents and mixed solvents. Hydrophilic PTFE membrane is the strongest membrane filter for strong acid, alcohol, and so on.
Polytetrafluoroethylene (PTFE, Teflon) Membrane Information PTFE is an inherently hydrophobic membrane excellent for filtration of organic-based, highly acidic or basic samples and solvents. Widely used in chromatography, it is especially well suited for the clarification of non-aqueous samples.
filter for most applications. PTFE Polytetrafluoroethylene(PTFE) - Phenex-PTFE membranes are inherently hydrophobic and excellent for filtration of 100 % organic or highly acidic or basic samples. PES Polyethersulfone(PES) - Polyethersulfone membranes
