Polyvinylidene Fluoride (PVDF) Syringe Filters - SPEC18222

Pharmaceutical and biotechnology laboratories require compact sterile filtration for small-volume organic solvent samples where chemical resistance and bacterial retention both matter for contamination-free processing. Advanced 0.22µm PVDF membrane technology delivers sterile-grade filtration with exceptional solvent compatibility and ready-to-use gamma-irradiated integrity. Hydrophobic construction in 20mm ABS housing with threaded double luer lock provides bacterial removal for HPLC mobile phases, LC-MS samples, and chemical formulations where space-efficient processing and contamination control drive analytical success.

Key PVDF Membrane Characteristics

• Hydrophobic surface chemistry requires alcohol pre-wetting before aqueous sample processing, ensuring proper membrane activation and consistent flow characteristics throughout filtration
• Exceptional chemical stability withstands acetonitrile, methanol, chlorinated solvents, and aggressive organic reagents that rapidly compromise cellulosic and polyamide membrane alternatives
• 0.22µm absolute pore size provides sterile-grade bacterial retention, protecting analytical systems from microbial contamination in critical pharmaceutical and biotechnology applications
• Ultra-low protein binding maintains biomolecule concentrations throughout filtration, preventing adsorptive losses that compromise quantitative accuracy in your protein analysis workflows
• Temperature tolerance to 80°C accommodates elevated-temperature sample processing while maintaining chemical compatibility across diverse laboratory operational conditions

Key Construction Characteristics

• ABS housing delivers chemical resistance to common organic solvents while providing mechanical durability for manual filtration operations in routine sample preparation
• Threaded double luer lock connection ensures secure, leak-proof attachment to syringes and transfer lines, preventing disconnection during processing workflows
• 72.5psi maximum operating pressure supports manual syringe filtration and integration with low-pressure pumping systems for automated sample preparation
• Sterile gamma-irradiated packaging provides contamination-free filtration without requiring pre-use sterilization, streamlining workflows in pharmaceutical and biotechnology cleanroom environments

Designed for your space-constrained analytical workflows where compact sterile filtration meets demanding organic solvent compatibility requirements. PVDF's chemical versatility handles the diverse solvents your laboratory processes. Sterile individually-wrapped units maintain your contamination control protocols while delivering the solvent resistance and bacterial retention that protect analytical instrumentation, preserve sample integrity, and ensure reliable results across demanding HPLC, LC-MS, and pharmaceutical applications where sterile-grade filtration capacity determines analytical success.
