Pura Disc 13mm PES Syringe Filters, 0.45um, 100/Pk
Whatman SKU: 6782-1304

Whatman Puradisc Polyethersulfone (PES) Syringe Filters, 0.45 µm, 13 mm, 100/Pk - 6782-1304

Whatman's established manufacturing platform delivers the consistency and lot-level documentation that analytical laboratories require. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. PES stays stable across the full pH 1 to 14 range while accepting water-based reagents without preconditioning and clarifies particulates at the rated pore size. Polypropylene construction maintains a low-dead-volume internal flow path while keeping the fluid path low in extractable contamination and resists aqueous acids, bases, and alcohols. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• Low protein binding preserves dilute analytes for maximum recovery
• Stable across the full pH 1 to 14 operating range
• Absolute pore size rating gives consistent results across protocols
• High flow rate with low extractable background for clean preparations
• Broad compatibility with aqueous buffers, aliphatic alcohols, glycols, and strong bases

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Low extractable contribution protects sensitive downstream analyses

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. General-purpose aqueous filtration supports the sample types you handle every day so you can standardize one filter across most aqueous methods.
