Polyvinylidene Fluoride (PVDF) Syringe Filters - SPEC18217

Laboratory workflows requiring flexible sterilization options face limitations when pre-sterilized filters add unnecessary cost to routine sample preparation where you can autoclave before use. Nonsterile 0.22µm PVDF membrane construction delivers economical sterile-grade filtration capability with user sterilization flexibility. Hydrophobic polyvinylidene fluoride in compact 20mm ABS housing with threaded double luer lock connection provides chemical-resistant bacterial retention for HPLC mobile phases, organic solvents, and biological samples after autoclave sterilization.

Key PVDF Membrane Characteristics

• Hydrophobic membrane requires alcohol pre-wetting before aqueous processing, activating the surface for proper flow and preventing air-lock conditions during sample filtration
• Exceptional chemical compatibility resists degradation from acetonitrile, methanol, chlorinated solvents, and aggressive organic reagents that rapidly compromise cellulosic membrane alternatives
• 0.22µm absolute pore size provides sterile-grade bacterial retention after user sterilization, protecting analytical systems from microbial contamination in critical applications
• Ultra-low protein binding maintains biomolecule concentrations throughout filtration, preventing adsorptive losses that compromise quantitative accuracy in your protein analysis workflows
• Temperature stability to 80°C supports both elevated-temperature sample processing and autoclave sterilization cycles without membrane degradation or performance loss

Key Construction Characteristics

• ABS housing provides chemical resistance to common laboratory solvents while delivering mechanical strength 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 accommodates manual syringe filtration and integration with low-pressure pumping systems for automated sample preparation
• Nonsterile construction with autoclave capability allows user sterilization before first use, providing economical sterile filtration while eliminating gamma-irradiation costs

Designed for your routine analytical workflows where sterile-grade filtration matters but pre-sterilized filters add unnecessary costs to sample preparation budgets. PVDF's chemical versatility combined with autoclave sterilization capability delivers the flexibility your laboratory needs. Economical nonsterile units become sterile-ready after autoclaving, providing the solvent resistance and bacterial retention that protect analytical instrumentation, maintain sample integrity, and support reliable results across demanding HPLC, LC-MS, and pharmaceutical applications.
