Acro Disc One Syringe Filters w/ wwPTFE Membrane - GxF/0.2um, 25mm, 200/Pk
Pall SKU: AP-4913

Pall Acrodisc Water-Wettable PTFE Syringe Filters, 0.2 µm, 25 mm, 200/Pk - AP-4913

Quality controls spanning raw membrane casting through final device integrity testing ensure consistent performance across Pall production lots. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Hydrophilic PTFE filters aqueous and organic samples in one membrane and minimizes analyte loss to the surface. Polypropylene construction maintains housing integrity through the filtration run and routes flow to minimize backpressure in service. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Low protein binding preserves dilute analytes for maximum recovery
• Water-wettable surface wets directly with both aqueous and organic samples
• Universal compatibility across aqueous buffers and organic solvents
• Sterile-grade retention at sub-micron pore sizes
• Chemically inert to aggressive organic solvents, strong acids, and alkalis

Housing Specifications

• Resists stress cracking from aqueous salt and buffer solutions
• Stable across the full aqueous pH range in routine sample work
• Optimized internal geometry minimizes backpressure in service
• Resists aqueous acids, bases, and alcohols in routine sample prep

Upstream clarification pays for itself by keeping your columns clear and your analytical day on schedule. Pre-injection filtration protects the resolution your methods depend on so your retention times and peak shapes stay consistent.

• Sample Protection - Low-binding properties ensure maximum recovery of low-concentration analytes to improve the accuracy of quantitative assays
• Universal Filtration - Handles both aqueous and organic samples with a single device, reducing inventory complexity and preventing selection errors
• Dissolution Testing - Simplifies workflows by filtering diverse media types without the need for pre-wetting, streamlining high-volume protocols
• Solvent Selection - Eliminates the risk of membrane incompatibility when switching between different solvent systems during method development
• UHPLC/HPLC Prep - Certified for low extractables to ensure noise-free baselines in sensitive chromatography applications and trace analysis
• Ion Chromatography - Provides a clean filtrate for sensitive ion analysis, minimizing background interference and ensuring accurate quantification
