Acro Disc Syringe Filters w/ Supor Membrane, Sterile - 1.2um, 32mm, 50/Pk
Pall SKU: 4656

Pall Acrodisc Polyethersulfone (PES) Syringe Filters, 1.2 µm, 32 mm, 50/Pk - 4656

Pall Corporation engineers proprietary membrane media and the Acrodisc housing platform, purpose-built for demanding analytical and bioprocess workflows. Syringe filters mount on a syringe to clarify a sample in a single manual pass. The PES membrane draws aqueous buffers through without pre-wetting while staying stable across the pH 1 to 14 range and clarifies particulates at the rated pore size. The PP housing keeps the fluid path low in extractable contamination and resists degradation from routine sample matrices. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• Stable across the full pH 1 to 14 operating range
• High flow rate with low extractable background for clean preparations
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• Absolute pore size rating gives consistent results across protocols
• Broad compatibility with aqueous buffers, aliphatic alcohols, glycols, and strong bases

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Rigid polypropylene body holds its shape under manual filtration pressure
• Tough polypropylene body tolerates repeated handling at the bench
• Optimized internal geometry minimizes backpressure in service

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. General-purpose aqueous filtration supports the sample types you handle every day from reagent and buffer preparation through routine sample clarification.

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