Pall
Acro Disc Syringe Filters w/ Supor Membrane - 1.2/0.45um, 32mm Modified Acrylic Housing, 1000Pk SKU: 4661

Polyethersulfone (PES) Syringe Filters, 1.2µm, 32mm - 4661

Optimized for biological performance, the Supor® Syringe Filters combines high flow rates with the assurance of low preservative binding. At the core of the device is the specialized polyethersulfone matrix, which resists clogging to filter greater volumes of biological fluids. 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.

• 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
• 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
• 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
