PTFE Hydrophobic Membrane Filter, 0.45µm, 47mm, PP-Supported, Nonsterile, 100/Pk SKU: LE-IWT-PTFE-045047

Featuring polytetrafluoroethylene membrane technology with polypropylene scrim support delivering exceptional chemical resistance and hydrophobic performance for organic solvent filtration applications. The 0.45µm pore configuration provides excellent chemical stability and inertness while exhibiting outstanding chemical resistance for filtering corrosive and aggressive liquids, gases, and solvents. Polypropylene lamination enhances durability and handling while maintaining chemical compatibility with strong acids and aggressive solvents including alcohols.

Key PTFE Membrane Characteristics

Chemically inert PTFE construction compatible with wide range of solvents and aggressive chemicals for harsh filtration environments
Inherent hydrophobic properties effectively separate polar/nonpolar solvents and oil-water mixtures in analytical applications
Temperature stability up to 260°C with biological inertness for high-temperature solvent and gas filtration processes
Low extractables construction reduces contamination risk while non-stick surface prevents particle adherence during filtration
Becomes hydrophilic after methanol or ethanol pre-wetting, enabling versatile aqueous solution filtration capabilities

Key Construction Characteristics

Polypropylene scrim support bonded without adhesive agents maintains chemical purity and reduces extractable compounds
Permanently hydrophobic membrane resists moisture absorption from air and gases for reliable venting and gas filtration applications
Superior pH compatibility from 1-14 accommodates extreme acid and base filtration requirements in analytical laboratories
Standard 47mm diameter fits universal filter holder configurations for seamless integration with existing filtration systems
Autoclave-compatible construction enables sterilization protocols for pharmaceutical and biotechnology sterile filtration applications

LE-IWT-PTFE-045047 filters deliver reliable 0.45µm retention for particulate removal while maintaining high flow rates in organic solvent applications. Outstanding performance in air and gas filtration, HPLC mobile phase preparation, and LC-MS sample preparation ensures optimal analytical system performance.
