Hydrophobic PVDF Syringe Filter, 0.22µm, 25mm, Nonsterile, Luer-Lock, 100/pk SKU: LE-IWT-ES10049

Featuring hydrophobic polyvinylidene fluoride membrane technology delivering superior chemical resistance and minimal protein binding for demanding organic solvent and biological sample filtration. The hydrophobic PVDF construction provides exceptional tolerance to corrosive solvents, strong acids, alcohols, alkali, and aromatic agents with excellent chemical resistance, while maintaining reliable performance up to 60°C maximum operating temperature. Ultra-low protein binding properties minimize sample adsorption and reduce biomolecule loss, ensuring accurate analytical results in protein and biomolecule analysis.

Key Membrane Characteristics

Polyvinylidene fluoride construction delivers exceptional chemical resistance and durability against wide range of solvents, acids, and bases
Hydrophobic membrane repels water and aqueous solutions while allowing organic solvents and non-polar liquids to pass through efficiently
Lowest protein adsorption among syringe filters with high flow rates for rapid sample processing
Compatible with most chemicals while maintaining stability - only limited by oleum, strong bases, ketones, and ethers
Enables unhindered passage of moist air and gases under very low pressure while preventing aqueous solution passage

Key Construction Characteristics

Rugged polypropylene housing withstands autoclave sterilization to 121°C for 15 minutes
Female Luer-lock inlet delivers leak-tight syringe connection with secure attachment during filtration
Internal pre-filter construction with strong polypropylene housing prevents contaminant mixing and reduces leakage potential
Maximum housing pressure of 150 psi enhances filtration speed for high-throughput applications
25mm diameter optimized for sample volumes of 10-100ml with holdup volume less than 100µl

LE-IWT-ES10049 filters excel in preparing and cleaning HPLC and GC samples, sterilizing enzyme and protein solutions, and filtering chromatography samples, buffers, and mobile phases with optimal compatibility for analytical applications. Outstanding chemical compatibility with alcohols, weak acids, proteins, and biomolecules combined with low extractables and UV transparency makes these filters particularly valuable for protein and peptide solutions, Western and Northern blot buffers, and general HPLC and GC preparation protocols. Broad solvent compatibility with wide range of organic compounds, acids, bases, and aqueous solutions maximizes laboratory versatility for both routine sample preparation and specialized analytical chemistry applications demanding reliable hydrophobic membrane performance.
