Acro Disc Syringe Filters w/ Supor Membrane - 0.2um, 13mm, Minispike Outlet, 1000/Pk
Pall SKU: 4692

Pall Acrodisc Polyethersulfone (PES) Syringe Filters, 0.2 µm, 13 mm, 1000/Pk - 4692

Quality controls spanning raw membrane casting through final device integrity testing ensure consistent performance across Pall production lots. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. PES handles strong bases and oils across a broad aqueous range while providing sterile-grade retention at sub-micron pore sizes and preserves dilute proteins and analytes in the filtrate. Polypropylene construction holds extractable contribution low for sensitive analyses while staying inert across common laboratory solvents 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

• Sterile-grade retention at sub-micron pore sizes
• Stable across the full pH 1 to 14 operating range
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• Broad compatibility with aqueous buffers, aliphatic alcohols, glycols, and strong bases
• High flow rate with low extractable background for clean preparations

Housing Specifications

• Resists stress cracking from aqueous salt and buffer solutions
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Low extractable contribution protects sensitive downstream analyses
• Stable across the full aqueous pH range in routine sample work

Filtering every buffer before loading keeps your instrument running clean and uninterrupted. Reliable particulate removal protects your instruments and your data across reagent, buffer, and mobile-phase preparation.

• 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
• Time-Sensitive Prep - Accelerates filtration workflows where speed is critical to preserving sample integrity and preventing biological degradation
• 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
