Polyvinylidene Fluoride (PVDF) Syringe Filters - SF17398

Laboratories processing aqueous biological samples in high-throughput environments face the dual challenge of maintaining rapid filtration rates while preventing membrane fouling from protein-rich solutions. Hydrophilic polyvinylidene fluoride membrane technology with 0.45 µm pore size addresses this challenge through naturally wettable surface chemistry that eliminates pre-treatment steps and reduces processing time. Additionally, the integrated glass fiber prefilter extends membrane life by capturing particulate matter before it reaches the primary filtration layer, enabling consistent performance across extended sample batches. This dual-layer configuration combines 4.6 cm² filtration area with 100 µL holdup volume, maximizing sample recovery for routine analytical workflows requiring efficient clarification without sterile-grade specifications.

Key Hydrophilic PVDF Membrane Characteristics

Naturally wettable surface eliminates alcohol pre-wetting requirements, enabling immediate processing of aqueous samples without preparatory steps or solvent waste
Broad chemical compatibility withstands organic solvents and aggressive pH conditions while maintaining stable operation across diverse analytical applications
Low protein binding characteristics preserve biomolecule concentration during filtration, minimizing sample loss in protein assays and biological preparations
0.45 µm pore size delivers reliable clarification performance for particulate removal in HPLC mobile phase preparation and sample cleanup procedures
Superior flow characteristics accelerate processing with a 39ml/ min flow rate, reducing filtration time for routine quality control and research applications

Key Construction Characteristics

100 µL holdup volume preserves samples by minimizing retention within the filter housing, optimizing yield for valuable biological extracts and analytical standards
Polypropylene housing withstands temperatures up to 60°C with 87 psi burst pressure, providing operational confidence for pressurized filtration systems
Dual Luer-Lok and Luer-Slip connections accommodate diverse syringe types without requiring adapters, streamlining workflow integration across laboratory equipment platforms
Glass fiber prefilter configuration captures coarse particles and extends membrane lifetime, reducing filter consumption in high-particulate sample processing applications

Bioanalytical and pharmaceutical laboratories processing high-volume aqueous samples require clarification technology that balances throughput efficiency with protein recovery. Hydrophilic PVDF syringe filters deliver 0.45 µm clarification performance through naturally wettable membrane chemistry and integrated prefilter protection. Designed for your most demanding sample preparation workflows, this dual-layer technology provides processing confidence via validated chemical resistance, low protein binding, and extended membrane lifetime for routine analytical applications requiring rapid clarification without bacterial retention capabilities.
