Hydrophobic PTFE Membrane Filter, 0.45µm, 90mm, PP Scrim Support, Nonsterile, 100/Pk SKU: LE-IWT-PTFE-045090

Featuring hydrophobic polytetrafluoroethylene membrane technology with polypropylene scrim reinforcement delivering exceptional chemical resistance for phase separation and solvent filtration applications. Inherently hydrophobic construction resists moisture absorption from air and gases, making it ideal for venting applications, phase separations and aerosol sampling. Unique bonding technique eliminates bonding agents for superior purity, chemical compatibility and lower extractables. Aqueous solutions can be processed after prewetting with methanol or other water-miscible fluids.

Key PTFE Membrane Characteristics

• Extremely hydrophobic PTFE construction exhibits superior chemical compatibility with aggressive solutions including strong acids, bases, and organic solvents
• 0.45µm pore size provides precise particulate retention while maintaining optimal flow rates for filtration efficiency
• Hydrophobic material effectively separates polar and nonpolar solvents for enhanced phase separation performance
• Maximum operating temperature of 260°C withstands high-temperature processing without membrane degradation
• Allows air to pass easily through membrane while collecting particulate as small as 0.1 micron on surface

Key Construction Characteristics

• Polypropylene scrim support provides enhanced handling strength and reduces membrane cracking during installation
• Scrim bonded using unique technique utilizing no bonding agent for purity, chemical compatibility and lower extractables
• 90mm diameter accommodates standard filtration equipment and holder configurations for versatile laboratory use
• Nonsterile format ready for immediate use in routine analytical and industrial filtration applications
• 100 filters per package with interleaved separator papers ensures easy handling and prevents membrane damage during storage

LE-IWT-PTFE-045090 membranes deliver reliable performance for non-aqueous fluid filtration, air and gas filtration, and venting applications. Hydrophobic nature makes them effective for oil-water separation processes and aerosol sampling for air quality monitoring where moisture repelling properties ensure accurate particle collection. Outstanding chemical inertness maximizes compatibility with aggressive solvents, transforming these membranes into versatile filtration media for demanding analytical, pharmaceutical, and industrial applications requiring both chemical resistance and precise particulate retention.
