Pura Disc 13mm PES Syringe Filters, 0.2um, 50 Pk
Whatman SKU: 6780-1302

Whatman Puradisc Polyethersulfone (PES) Syringe Filters, 0.2 µm, 13 mm, 50/Pk - 6780-1302

Whatman's expertise in cellulose, glass fiber, and polymeric membrane production guides material selection and quality control. Syringe filters mount on a syringe to clarify a sample in a single manual pass. The PES membrane draws aqueous buffers through without pre-wetting and keeps protein adsorption low across the run. The PP housing prevents sample bypass under rated operating pressure while staying inert across common laboratory solvents and holds extractables low for sensitive analyses. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Sterile-grade retention at sub-micron pore sizes
• Stable across the full pH 1 to 14 operating range
• Low protein binding preserves dilute analytes for maximum recovery
• High flow rate with low extractable background for clean preparations
• Absolute pore size rating gives consistent results across protocols

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Thermal-bonded construction keeps adhesives out of the fluid path
• Low extractable contribution protects sensitive downstream analyses
• Medical-grade polypropylene with broad chemical compatibility

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. Consistent aqueous clarification keeps your sample preparation moving as a dependable step in your aqueous sample prep.
