Hydrophilic Polyvinylidene Fluoride (PVDF) Syringe Filters - SPEC18228

Laboratories processing aqueous samples often struggle with the pre-wetting steps required by standard hydrophobic membranes. Hydrophilic PVDF syringe filters with a 0.22 µm pore size eliminate this variable, allowing immediate filtration of water-based fluids. The 25mm polypropylene housing features secure Double Luer Lock connections to prevent leaks during processing. While supplied nonsterile, these units are fully autoclavable, offering cost-effective sterility for routine applications. The design combines the low protein binding of PVDF with the convenience of direct aqueous compatibility. Researchers rely on this versatile solution for HPLC preparation and biological filtration.

Key Hydrophilic PVDF Membrane Characteristics

• Hydrophilic surface treatment enables direct aqueous sample processing without alcohol pre-wetting, eliminating preparation steps
• Exceptional chemical stability maintains structural integrity when filtering diverse solvents and reagents, providing broad compatibility
• 0.22 µm absolute pore size provides sterile-grade bacterial retention after user sterilization, protecting analytical systems
• Ultra-low protein binding preserves biomolecule concentrations throughout filtration, preventing adsorptive losses that compromise quantitative accuracy
• Autoclavable construction allows user sterilization before first use, providing economical sterile-grade filtration

Key Construction Characteristics

• Polypropylene housing delivers chemical compatibility with common laboratory solvents while providing mechanical strength for manual filtration
• Double Luer Lock connections secure both inlet and outlet ports to eliminate disconnection risks
• 25mm diameter platform supports medium-volume clarification for samples up to 100 mL balancing capacity with economy
• Nonsterile construction with autoclave capability allows user sterilization before first use providing flexible contamination control

Maximize your laboratory efficiency with a filtration solution designed for both aqueous and organic compatibility. You can process biological samples immediately without the delay of alcohol priming. The 0.22 µm pore size ensures the complete removal of bacteria from critical fluids. Double Luer Lock connections provide a secure seal when filtering samples under pressure. Autoclavable construction allows you to sterilize units only when necessary, reducing operational costs. The robust design protects analytical instruments while preserving the integrity of sensitive biomolecules. Choose this flexible filter for your most demanding aqueous applications.
