Pall Acrodisc PVDF Syringe Filters, 0.2 µm, 25 mm, 1000/Pk - AP-4797

Pall Corporation brings decades of fluid management expertise to laboratory-scale filtration challenges. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. Ultra-low-binding PVDF preserves dilute proteins and analytes in the filtrate and achieves sterile-grade retention at sub-micron pore sizes. The polypropylene housing contributes minimal extractables to the filtrate while maintaining housing integrity through the filtration run and resists degradation from routine sample matrices. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• Ultra-low protein binding preserves dilute analytes for maximum recovery
• Thin membrane structure sustains high flow for fast sample throughput
• Hydrophilic surface wets aqueous and HPLC samples without pre-wetting
• Resists HPLC mobile phases, alcohols, and mild hydrocarbons
• Sterilizing-grade retention at sub-micron pore sizes

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Stable across the full aqueous pH range in routine sample work
• Low extractable contribution protects sensitive downstream analyses
• Rigid polypropylene body holds its shape under manual filtration pressure

Filtering particulates upstream protects the column investment your methods depend on. Reliable particulate removal protects your instruments and your data across reagent, buffer, and mobile-phase preparation. Ask our friendly customer service team to confirm the pore size, membrane, and sterility options your filtration application calls for.

• Protein Purification - Facilitates the routine clarification of chromatography samples, preventing column fouling without binding target proteins
• Western Blotting - Ensures ultra-low protein binding for maximum sample recovery, critical for sensitive immunodetection protocols and assays
• Spectroscopy - Provides optical clarity and low background interference, making it ideal for UV-Vis and fluorescence sample preparation
• Immunochemistry - Delivers exceptional chemical resistance for mild organic mixtures used in sensitive immunochemical research applications
• Trace Analysis - Prevents non-specific binding in trace analysis, ensuring that low-concentration analytes remain in solution for detection
• Biological Samples - Clarifies protein-rich solutions without loss of target molecules, preserving sample integrity for critical downstream assays
