Polyvinylidene Fluoride (PVDF) Syringe Filters - SF17398

Laboratories processing aqueous biological samples in high-throughput environments face specific challenges. Rapid filtration rates must be maintained while preventing membrane fouling from protein-rich solutions. Hydrophilic polyvinylidene fluoride membrane technology with 0.45 µm pore size addresses these issues. Naturally wettable surface chemistry eliminates pre-treatment steps and reduces processing time. An integrated glass fiber prefilter extends membrane life by capturing particulate matter upstream. The dual-layer configuration combines a generous 6.5 cm² filtration area with a 100 µL holdup volume. Users maximize sample recovery for analytical workflows requiring clarification.

Key Hydrophilic PVDF Membrane Characteristics
