Pura Disc 13mm PES Syringe Filters, 0.2um, 100/Pk
Whatman SKU: 6782-1302

Whatman Puradisc Polyethersulfone (PES) Syringe Filters, 0.2 µm, 13 mm, 100/Pk - 6782-1302

Whatman applies the same process controls across its filtration portfolio, verifying rated performance at the production lot level. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. PES handles strong bases and oils across a broad aqueous range while preserving dilute proteins and analytes in the filtrate and achieves sterile-grade retention with high recovery. The polypropylene housing contributes minimal extractables to the filtrate and holds a reliable seal against the membrane edge. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Absolute pore size rating gives consistent results across protocols
• Stable across the full pH 1 to 14 operating range
• High flow rate with low extractable background for clean preparations
• Sterile-grade retention at sub-micron pore sizes
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Medical-grade polypropylene with broad chemical compatibility
• Low extractable contribution protects sensitive downstream analyses

Filtering every buffer before loading keeps your instrument running clean and uninterrupted. Upstream buffer clarification keeps avoidable particulates out of your flow path before they reach the column inlet or detector. Review our Chemical Compatibility Chart, or ask technical service to confirm chemical compatibility for your specific application.

• Culture Media Filtration - PES offers the fastest flow rates for viscous culture media while maintaining absolute sterility
• Ion Chromatography - The extremely low extractable profile of PES provides the clean baselines needed for sensitive IC analysis
• Biological Sample Prep - The low protein-binding nature of PES ensures maximum recovery of critical enzymes and proteins
• Life Science Applications - Ideal for filtering serum and plasma, where minimizing nonspecific binding is crucial for assay accuracy
• Sample Clarification - Optimizing sample clarity via rapid filtering of contaminants to maintain high throughput in busy laboratories
• Environmental Monitoring - Ideal for filtering pollutants in water and wastewater analysis to ensure regulatory compliance
