Made from polytetrafluoroethylene (PTFE) bonded to high-density polyethylene. Wetting with methanol or another low-surface-tension fluid renders the membrane hydrophilic. Mean thickness varies from 145 to 200μm, depending upon filter type. Provides broad chemical compatibility.

filtration since the filters would block flow if inadvertently wetted, by condensation for example.Hydrophobic. membrane filters are typically used with compatible non-aqueous fluids. They are also commonly used as. air, gas, or vent filters. Hydrophobic membrane filters are sometimes used with water or aqueous.
Our versatile PVDF membrane filters are available with pore sizes of either 0.22 or 0.45 μm; however, the 0.22 μm pore size is preferred for the removal of uHPLC contaminants most likely plug columns and damage analytical results. Start with a custom PVDF membrane sample pack here. Hide.

Hydrophilic membrane filters are typically used with water and aqueous solutions. They can also be used with compatible non-aqueous fluids. Hydrophilic membrane filters are typically not used for air, gas or vent filtration since the filters would block flow if inadvertently wetted, by condensation for example.
PTFE has a nar- rower temperature range for hot gas filtration than ceramic, but it has an excellent elasticity and quite low adhesion and friction [11], so PTFE membrane filter membrane has more advantages in re- generation, maintenance and replacement of
HYDROPHILIC PTFE SYRINGE FILTERS: Virgin PP housing with Hydrophilic PTFE membrane (PP support layer). Diameter 25mm, Pore Size: 0.22μm. HYDROPHILIC PTFE FEATURES: Hydrophilic PTFE membrane has good mechanical strength, tear resistance, the contact angle of less than 20 °, good bubble point , high porosity, high flow rate.
Hydrophilic PTFE ( Polytetrafluoroethylene) Syringe Filter Features and Advantages: Hydrophilic; Chemically resistant to all solvents, acids and bases; PTFE membrane with supporting layer polyester or polypropylene; High temperature resistance
Advantec Hydrophilic PTFE membrane filters are ideal for HPLC and other mixtures of aqueous and organic solvents. This non-supported membrane is very thin and optically clear when wet. Thermostable up to 100°C. Note: Allowing the filter to dry will render it hydrophobic.
See below for stock. Camlab PTFE membrane filters are hydrophobic, available with 0.22µm or 0.45µm pore size. Description. Compatibility. Description. Naturally hydrophobic, the PTFE membranes are made with polytetra-fluoroethylene laminated with a PP layer.
These hydrophobic PTFE membrane filters are laminated onto polypropylene netting for improved strength and handling. Due to broad chemical compatibility and excellent water repellency, they are ideal for solvent filtration, phase separations, venting, and air sampling.
