Acro Disc Syringe Filters w/ Supor Membrane, Sterile - 0.1um, 32mm, 50/Pk
Pall SKU: 4651

Pall Acrodisc Polyethersulfone (PES) Syringe Filters, 0.1 µm, 32 mm, 50/Pk - 4651

Pall Corporation engineers proprietary membrane media and the Acrodisc housing platform, purpose-built for demanding analytical and bioprocess workflows. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. The PES membrane draws aqueous buffers through without pre-wetting while achieving sterile-grade retention with high recovery and handles strong bases across a broad aqueous range. The polypropylene housing routes flow to minimize backpressure in service and maintains housing integrity through the filtration run. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• High flow rate with low extractable background for clean preparations
• Sterile-grade retention at sub-micron pore sizes
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• Stable across the full pH 1 to 14 operating range
• Absolute pore size rating gives consistent results across protocols

Housing Specifications

• Thermal-bonded construction keeps adhesives out of the fluid path
• Stable across the full aqueous pH range in routine sample work
• Tough polypropylene body tolerates repeated handling at the bench
• Plasticizer-free polyolefin construction keeps the fluid path clean

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. General-purpose aqueous filtration supports the sample types you handle every day across your water-analysis and general analytical workflows.

• 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
• Biologicals - Maximizes recovery of high-value proteins and therapeutics during sterile filtration steps, protecting yield in production runs
• 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
• Time-Sensitive Prep - Accelerates filtration workflows where speed is critical to preserving sample integrity and preventing biological degradation
