Hydrophilic Polyvinylidene Fluoride (PVDF) Syringe Filters - SPEC18228

Precision 0.22µm hydrophilic polyvinylidene fluoride membrane construction in nonsterile 25mm polypropylene housing delivers sterile-grade bacterial retention capability with specialty surface treatment eliminating pre-wetting requirements for aqueous samples. Direct aqueous processing streamlines workflows compared to standard hydrophobic PVDF requiring alcohol activation. Autoclavable design with double luer lock connection supports HPLC sample preparation, biological sample processing, and pharmaceutical applications where user sterilization flexibility combines with immediate aqueous compatibility and exceptional chemical resistance for demanding laboratory workflows.

Key Hydrophilic PVDF Membrane Characteristics

• Hydrophilic surface treatment enables direct aqueous sample processing without alcohol pre-wetting, eliminating preparation steps and streamlining your filtration workflows for water-based applications
• Exceptional chemical stability maintains structural integrity when filtering diverse solvents and reagents, providing broader compatibility than cellulosic membranes in your analytical applications
• 0.22µm absolute pore size provides sterile-grade bacterial retention after user sterilization, protecting analytical systems and cell culture from microbial contamination in critical applications
• Ultra-low protein binding preserves biomolecule concentrations throughout filtration, preventing adsorptive losses that compromise quantitative accuracy in your protein analysis and biological workflows
• Autoclavable construction allows user sterilization before first use, providing economical sterile-grade filtration while eliminating gamma-irradiation costs in routine laboratory operations

Key Construction Characteristics

• Polypropylene housing delivers chemical compatibility with common laboratory solvents while providing mechanical strength for manual filtration operations in routine sample preparation
• Double luer lock connection creates secure, leak-proof attachment to syringes and transfer lines, preventing disconnection during processing workflows
• 25mm diameter provides medium-volume processing capacity suitable for 10-100ml sample volumes in routine analytical and biological sample preparation applications
• Nonsterile construction with autoclave capability allows user sterilization before first use, providing flexible contamination control while reducing costs compared to pre-sterilized alternatives

When your laboratory processes aqueous samples requiring sterile-grade filtration without the complexity of hydrophobic membrane pre-wetting or costs of pre-sterilized units. Hydrophilic PVDF combines immediate aqueous compatibility with autoclave sterilization capability. Economical nonsterile units become sterile-ready after autoclaving, providing the chemical resistance and bacterial retention that protect analytical instrumentation, maintain sample integrity, and ensure reliable results across demanding HPLC, biotechnology, and pharmaceutical applications where processing simplicity and sterilization flexibility both matter.
