PES Syringe Filter w/ Glass Fiber Prefilter, 0.45µm, 25mm, Hydrophilic, Nonsterile, 100/Pk SKU: LE-IWT-ES10209

Featuring dual-layer hydrophilic polyethersulfone membrane technology with integrated glass microfiber prefilter delivering exceptional throughput for particle-laden sample processing applications. The 0.45µm PES membrane provides high porosity asymmetric pore structure with intrinsically low protein binding characteristics, while the glass fiber prefilter reduces particle loading experienced by the membrane final filter and protects against early clogging to increase total throughput. Maximum operating temperature of 60°C with compatible fluids enables processing of elevated temperature solutions requiring validated filtration protocols.

Key PES Membrane Characteristics

• Hydrophilic polyethersulfone construction provides maximum sample recovery with low protein and drug binding characteristics
• Optimized for highest flow rates with pH compatibility range of 3-12 for versatile analytical applications
• Minimal protein binding with robust and consistent pore structure enhances performance in life sciences applications
• Exceptional compatibility with acids, bases, and oxidizers for demanding chemical filtration requirements
• High flow rate with low dissolution characteristics ensures sample integrity without contamination or adsorption

Key Construction Characteristics

• Graduated glass fiber prefilter eliminates larger particles while providing significantly higher throughput compared to standard filters lacking prefiltration media
• Effective filtration of highly viscous samples with high compatibility to organic solvents, strong acids and alkalis
• Medical-grade PP plastic housing with ultrasonic welding, non-slip design, and high-pressure resistance prevents product leakage
• Female luer lock inlet connection with male luer slip outlet connection provides leak-tight syringe attachment
• Suitable for both manual and automated applications with low-extractable polyethylene housing construction

LE-IWT-ES10209 filters achieve superior particle retention capacity for tissue culture media, protein solutions, and high-particulate analytical samples requiring pre-clarification before instrumental analysis. Particularly appropriate for ion chromatography samples, tissue culture filtration, and filtration of proteins and nucleic acids by removing interfering substances and fine particulates down to the designated pore size. Incorporating syringe filtration prior to chromatographic injection ensures more reliable and consistent results while protecting delicate instruments and prolonging column lifespan, maximizing your analytical precision for HPLC, GC, and dissolution analysis applications demanding both high throughput and validated sample purity.
