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 standardizes its manufacturing platform to the point that consistency and thorough lot-level records come as a default, exactly what analytical laboratory work demands. At the sub-micron pore rating, a syringe filter delivers sterilizing-grade retention at the point of use. PES provides sterile-grade retention at the rated sub-micron pore size while pairing fast flow with reduced protein adsorption and admits aqueous reagents on contact, skipping any surfactant rinse. The polypropylene housing keeps the sample chemically unaltered across the pass while standing firm against aqueous acids, bases, and alcohols during regular handling and maintains structural integrity through elevated-temperature sample preparation. For workflows requiring validated sterile-grade performance, point-of-use retention meets it without a separate sterilization step.

Membrane Characteristics

• Finest available pore ratings achieve aseptic-grade filtration performance
• DNA and RNA pass through with negligible adsorptive loss
• Antibody and protein samples pass through PES with minimal adsorptive loss
• Pore structure integrity holds through autoclave cycles up to 126°C
• PFAS extractables test non-detectable under EPA Method 537.1

Housing Characteristics

• Minimal intrinsic autofluorescence from the polypropylene housing supports background-sensitive fluorescence-based assay work downstream.
• Low moisture absorption keeps the housing dimensionally stable through humid storage and shipping
• Resists stress cracking from aqueous salt and buffer solutions
• Polypropylene housing withstands operating temperatures up to 121°C without softening or dimensional distortion.

Hydrophilic

• Biological Assays - Protects sensitive enzymatic and antibody-based assays from particulate interference without adsorbing critical reagents.
• Sample Recovery - Minimizes sample loss in low-protein-binding applications, delivering high yield for precious or rare biological specimens.
• Cell Culture - Reduces the risk of mycoplasma contamination in growth media, supporting healthier cell lines and more reliable experimental outcomes.
• PFAS Water Testing - PES filters process aqueous samples for EPA Method 1633A PFAS testing without added fluorinated background.
• Nucleic Acid Recovery - Processes DNA and RNA extracts with minimal nucleic acid adsorption, preserving yield on the hydrophilic PES surface.
• Pesticide Residue Testing - PES membranes improve polar pesticide recovery in food-safety LC-MS/MS testing versus hydrogen-bonding nylon.
