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

Whatman Puradisc Polyethersulfone (PES) Syringe Filters, 0.45 µm, 13 mm, 50/Pk - 6780-1304

Whatman's established manufacturing platform delivers the consistency and lot-level documentation that analytical laboratories require. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. PES holds consistent absolute retention at the rated pore size while accepting water-based reagents without preconditioning and keeps protein adsorption low across the run. Polypropylene construction maintains housing integrity through the filtration run while sustaining efficient flow on viscous samples and stays inert across common laboratory solvents. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• High flow rate with low extractable background for clean preparations
• Broad compatibility with aqueous buffers, aliphatic alcohols, glycols, and strong bases
• Stable across the full pH 1 to 14 operating range
• Absolute pore size rating gives consistent results across protocols

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Thermal-bonded construction keeps adhesives out of the fluid path
• Medical-grade polypropylene with broad chemical compatibility

Reproducible separations start with samples that reach the column free of particulates. Upstream sample clarification keeps your separations clean and reproducible across your HPLC and UHPLC methods.

• 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
