Acro Disc PSF Syringe Filters w/ Supor Membrane - GxF/0.2um, 25mm, 200/Pk
Pall SKU: AP-4799

Pall Acrodisc Polyethersulfone (PES) Syringe Filters, 0.2 µm, 25 mm, 200/Pk - AP-4799

Pall Corporation brings decades of fluid management expertise to laboratory-scale filtration challenges. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. The PES membrane draws aqueous buffers through without pre-wetting while achieving sterile-grade retention with high recovery and keeps protein adsorption low across the run. The polypropylene housing routes flow to minimize backpressure in service while keeping the fluid path low in extractable contamination and holds a reliable seal against the membrane edge. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Stable across the full pH 1 to 14 operating range
• Low protein binding preserves dilute analytes for maximum recovery
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• High flow rate with low extractable background for clean preparations
• Sterile-grade retention at sub-micron pore sizes

Housing Specifications

• Thermal-bonded construction keeps adhesives out of the fluid path
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Rigid polypropylene body holds its shape under manual filtration pressure
• Optimized internal geometry minimizes backpressure in service

Sample clarification before injection is the cheapest insurance your chromatography system has. Pre-injection filtration protects the resolution your methods depend on so your retention times and peak shapes stay consistent.

• Time-Sensitive Prep - Accelerates filtration workflows where speed is critical to preserving sample integrity and preventing biological degradation
• High-Throughput Sterile Filtration - Processes large volumes of biological fluids significantly faster than standard PES to reduce processing time
• Media Preparation - Sterilizes tissue culture media with minimal protein loss, ensuring optimal cell growth and viability in sensitive cultures
• Buffer Filtration - Ensures particulate-free buffers for critical downstream processes and instrumentation to prevent costly system downtime
• Viscous Biologicals - Maintains flow rates even when filtering protein-rich or slightly viscous biological fluids that would clog other filters
• Biologicals - Maximizes recovery of high-value proteins and therapeutics during sterile filtration steps, protecting yield in production runs
