Pall
Acro Disc Syringe Filters w/ Supor Membrane, Sterile - 0.1um, 32mm, 50/Pk SKU: 4651

Polyethersulfone (PES) Syringe Filters, 0.1µm, 32mm - 4651

Designed for the biopharmaceutical sector, Supor® technology ensures sterility while minimizing the time your sensitive samples spend in filtration. Driving this biological efficiency is an ultra-low protein binding surface that minimizes the loss of active ingredients during sterile filtration. To guarantee structural reliability, each unit undergoes strict quality control to ensure the housing and membrane seal withstand standard operating pressures without leakage. 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

• 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-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
• 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
• 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
