Acro Disc Syringe Filters w/ Supor Membrane - Serum , Sterile - GF/0.2um, 37mm, 20/Pk
Pall SKU: 4525

Pall Acrodisc Polyethersulfone (PES) Syringe Filters, 0.2 µm, 37 mm, 20/Pk - 4525

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. Naturally hydrophilic PES wets on contact with aqueous samples while staying stable across the pH 1 to 14 range and preserves dilute proteins and analytes in the filtrate. The PP housing sustains efficient flow on viscous samples while resisting aqueous acids, bases, and alcohols in routine use and holds extractables low for sensitive analyses. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• Broad compatibility with aqueous buffers, aliphatic alcohols, glycols, and strong bases
• Absolute pore size rating gives consistent results across protocols
• Stable across the full pH 1 to 14 operating range
• High flow rate with low extractable background for clean preparations
• Low protein binding preserves dilute analytes for maximum recovery

Housing Specifications

• Resists stress cracking from aqueous salt and buffer solutions
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Rigid polypropylene body holds its shape under manual filtration pressure

Reproducible separations start with samples that reach the column free of particulates. Pre-injection filtration protects the resolution your methods depend on by clearing particulates ahead of the column and frits.

• 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
• 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
• Biologicals - Maximizes recovery of high-value proteins and therapeutics during sterile filtration steps, protecting yield in production runs
• Viscous Biologicals - Maintains flow rates even when filtering protein-rich or slightly viscous biological fluids that would clog other filters
