PVDF Syringe Filter with Glass Fiber Prefilter, 0.45µm, 25mm, Hydrophobic, 100/pk SKU: LE-IWT-ES10222

Featuring integrated glass fiber prefilter technology with hydrophobic PVDF membrane delivering exceptional throughput for particulate-laden sample processing. The glass fiber prefilter reduces particle loading on the primary membrane and extends service life, providing greater total throughput when filtering high-solids solutions. Ultra-low protein binding characteristics combined with 0.45µm pore precision makes these filters ideal for protein solutions, HPLC sample preparation, and demanding analytical applications requiring consistent performance.

Key PVDF Membrane Characteristics

Low protein binding properties optimize compatibility with protein solutions and mild organic solvents
Hydrophobic surface chemistry delivers reliable filtration of water-soluble oligomers and polymers without membrane wetting interference
Maximum operating temperature of 60°C maintains membrane integrity during elevated temperature applications
0.45µm absolute pore rating provides precise particle retention for analytical sample clarification
Excellent chemical compatibility with aggressive solvents while avoiding strong bases, acetone, DMF, and DMSO

Key Construction Characteristics

Binder-free glass fiber prefilter construction eliminates contamination while maximizing particulate loading capacity
Polypropylene housing with Luer-Lock® inlet and pressure fitting ensures secure, leak-free connections during operation
Concentric funnel-shaped barrel design increases sample volume capacity while decreasing back pressure for improved flow rates
Ultrasonic bonding technology delivers reliable housing integrity and consistent unit-to-unit performance
25mm diameter configuration accommodates standard syringe compatibility with optimal filtration area for laboratory applications

These prefilter-equipped devices provide two to four times the throughput of standard syringe filters, making them particularly valuable for dissolution testing and high-particulate sample processing. Superior performance in HPLC applications and aqueous sample filtration accelerates your analytical workflows while maintaining the flat baselines and low extractables essential for chromatographic accuracy. Nonsterile construction with clearly inscribed filter specifications ensures reliable identification and delivers the consistent lot-to-lot reproducibility demanded by quality control and research applications.
