Acro Disc Syringe Filters w/ Supor Membrane - Serum , Sterile - GF/0.2um, 37mm, 20/Pk SKU: 4525

Polyethersulfone (PES) Syringe Filters, 0.2µm, 37mm - 4525

When maximizing protein recovery is critical, the Supor® Syringe Filters delivers an ultra-low binding surface that protects your valuable active ingredients. 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. The result is a filtration solution manufactured in an ISO-certified facility that minimizes distinct interference, providing clean baselines for publication-quality data.

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
• 0.2 rating suitable for sterile filtration

Key Housing Characteristics

• High-purity Polypropylene encapsulation housing
• Luer-Lock/ Luer Slip for secure fitting
• 7.5cm² effective filtration area
• nan holdup volume to minimize sample loss

You can streamline your sample preparation process significantly by adopting a filtration solution designed to handle your specific volume requirements. Trust in the consistent performance of your filtration step to remove the variables that often lead to costly re-runs and ambiguous data. When performance cannot be compromised, rely on the brand that has defined the science of filtration for decades.

• 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
• Time-Sensitive Prep - Accelerates filtration workflows where speed is critical to preserving sample integrity and preventing biological degradation
• 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
• Viscous Biologicals - Maintains flow rates even when filtering protein-rich or slightly viscous biological fluids that would clog other filters
