Acro Disc Syringe Filters w/ Supor Membrane - 0.1um, 25mm Modified Acrylic Housing, 1000/Pk SKU: 4668

Polyethersulfone (PES) Syringe Filters, 0.1µm, 25mm - 4668

Supor® polyethersulfone (PES) membranes represent the industry gold standard for high-throughput sterile filtration of biological fluids. Central to this high-throughput capability is the Supor® PES membrane, optimized with an asymmetric pore structure to deliver superior flow rates. Designed to facilitate rapid processing, the housing features an optimized flow geometry that minimizes backpressure, allowing for easier manual filtration even with viscous samples. Ultimately, this rigorous attention to manufacturing quality ensures batch-to-batch reproducibility, allowing laboratories to standardize their workflows with total confidence.

Key Polyethersulfone (PES) Membrane Characteristics

• Polyethersulfone (PES) membrane with hydrophilic affinity
• Ultra-Low Protein Binding characteristics
• Broad compatibility (pH 1-14), ideal for biologicals
• Not compatible with aggressive ketones or esters
• 0.1 rating suitable for sterile filtration

Key Housing Characteristics

• High-purity Polypropylene encapsulation housing
• Luer-Lock/ Luer Slip for secure fitting

• 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
• Buffer Filtration - Ensures particulate-free buffers for critical downstream processes and instrumentation to prevent costly system downtime
• 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
