Acro Disc PSF Syringe Filters w/ Supor Membrane - GxF/0.45um, 25mm, 1000/Pk SKU: AP-4426

Polyethersulfone (PES) Syringe Filters, 0.45µm, 25mm - AP-4426

Optimized for biological performance, the Supor® Syringe Filters combines high flow rates with the assurance of low preservative binding. To ensure regulatory compliance, the Supor® membrane is validated for bacterial retention while offering faster processing than competitive PES. Encasing this critical media is a high-purity polypropylene housing that prevents sample bypass and ensures that every microliter is processed with high fidelity. Consequently, by reducing the risk of downstream contamination, these filters serve as a critical safeguard for the integrity of your experimental results.

Key Polyethersulfone (PES) Membrane Characteristics

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