Whatman
Pura Disc 13mm PES Syringe Filters, 0.45um, 50 Pk SKU: 6780-1304

Polyethersulfone (PES) Syringe Filters, 0.45µm, 13mm - 6780-1304

Streamline your sample preparation workflows with the Polyethersulfone (PES) Whatman Puradisc, 13mm, Syringe Filter, 0.45µm, sterile 50/pk, constructed to handle high particulate loads while maintaining rapid throughput. Driving this clarification performance is a hydrophilic Polyethersulfone (PES) membrane featuring a verified 0.45 pore structure that captures target particulates while minimizing holdup volume. Encasing this critical media is a high-purity polypropylene housing that prevents sample bypass and ensures that every microliter is processed with high fidelity. Meeting the needs of regulated environments, this series supports compliance with stringent purity protocols across pharmaceutical and environmental applications.

Key Polyethersulfone (PES) Membrane Characteristics

• Polyethersulfone (PES) membrane with hydrophilic affinity
• Low Protein Binding characteristics
• Broad compatibility with aqueous solutions, alcohols, and mild bases
• Ideal for biological samples and culture media
• Verified 0.45 retention rating for clarification

Key Housing Characteristics

• High-purity Polypropylene encapsulation housing
• Luer-Lok/ Luer Slip for secure fitting
• 1.3cm² effective filtration area
• <25µl 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. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.

• Culture Media Filtration - PES offers the fastest flow rates for viscous culture media while maintaining absolute sterility
• Life Science Applications - Ideal for filtering serum and plasma, where minimizing nonspecific binding is crucial for assay accuracy
• Biological Sample Prep - The low protein-binding nature of PES ensures maximum recovery of critical enzymes and proteins
• Ion Chromatography - The extremely low extractable profile of PES provides the clean baselines needed for sensitive IC analysis
• Analytical Sample Prep - Optimized to ensure data integrity by effectively removing particulates before instrumental analysis
• Biological Fluid Analysis - Protects sensitive downstream instruments from removing particulates that can cause system failure
