PVDF Syringe Filter w/ Glass Fiber Prefilter, 0.22µm, 13mm, Hydrophobic, Nonsterile, 100/pk SKU: LE-IWT-ES10219

Featuring advanced PVDF membrane technology with integrated glass fiber prefilter delivering exceptional flow rates and extended service life for demanding analytical applications. The hydrophobic polyvinylidene fluoride construction provides high strength, superior porosity, and rapid filtration while maintaining low extractable levels critical for HPLC, GC, and chromatographic sample preparation. The glass fiber prefilter reduces particle loading experienced by the primary membrane, extending filter service life and maximizing throughput for samples containing suspended solids.

Key PVDF Membrane Characteristics

• Hydrophobic PVDF membrane construction delivers high strength and porosity with rapid flow rates while minimizing extractables
• 0.22µm pore size provides reliable filtration for sterilization and bacterial removal in analytical protocols
• Lower protein binding compared to nylon or PTFE membranes ensures superior protein recovery in biological applications
• Optimized for filtration of water-soluble oligomers, polymers, and protein solutions with excellent chemical compatibility
• Broad solvent compatibility including organic solvents while maintaining membrane integrity and performance

Key Construction Characteristics

• Polypropylene medical-grade housing with Luer-Lock and Luer-Slip fittings compliant with ISO 594-1 standards
• 13mm diameter configuration optimized for 1-10mL sample volumes in routine analytical workflows
• Integrated glass fiber prefilter increases total throughput for high-particulate samples and viscous solutions
• External ring insert sealing maintains membrane integrity and optimal filtration performance
• Ultrasonically bonded construction ensures reliable unit-to-unit reproducibility and lot-to-lot consistency

This PVDF syringe filter configuration achieves superior performance in protein filtration, biological sample preparation, and organic solvent applications where low extractables and minimal protein binding are essential. The glass fiber prefilter delivers greater total throughput compared to standard filters, accelerating your analytical workflows while maintaining the chemical resistance and thermal stability required for demanding laboratory protocols. Nonsterile format provides cost-effective filtration for routine analytical applications requiring validated membrane performance without sterility requirements.
