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 draws on Cytiva's broader manufacturing oversight while continuing a legacy of filtration work that touches laboratory research, environmental monitoring, and industrial processing alike. A sterilizing-grade syringe filter carries manufacturer bacterial retention testing built into the design, giving analysts documented sterile-grade performance without repeating that testing in-house for the format. The PES membrane loads aqueous buffers with zero pre-wetting delay and screens out bacteria before they cross its finest pore rating. Polyolefin construction sheds virtually no extractable material into the sample while routing flow to minimize backpressure in service and maintains structural integrity through elevated-temperature sample preparation. The bench setup stays free of autoclave cycles and housing-maintenance steps once a single-use sterilizing-grade filter handles the preparation.

Technical Specifications

• Sulfone backbone's hydrolytic stability tolerates repeated autoclave steam sterilization cycles
• Absolute pore size rating holds consistent across every lot
• PFAS extractables test non-detectable under EPA Method 537.1
• Non-hydrogen-bonding surface avoids the polar adsorption nylon's amide backbone causes
• DNA and RNA pass through with negligible adsorptive loss

Housing Specifications

• PP housing rated to 121°C holds its geometry through high-temperature sample preparation and processing.
• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation.
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Burst pressure rating provides a wide safety margin above the rated maximum operating pressure.

Sample clarification before injection is the cheapest insurance your chromatography system has. Pre-injection filtration protects the resolution your methods depend on across your chromatography methods.

Hydrophilic

• Sample Recovery - Minimizes sample loss in low-protein-binding applications, delivering high yield for precious or rare biological specimens.
• Organic Carbon Testing - Clarifies water samples ahead of DOC and UV254 analysis while keeping organic carbon adsorption to the membrane minimal.
• Cell Culture - Reduces the risk of mycoplasma contamination in growth media, supporting healthier cell lines and more reliable experimental outcomes.
• Biological Assays - Protects sensitive enzymatic and antibody-based assays from particulate interference without adsorbing critical reagents.
• Urine Drug Screening - Clarifies protein-poor urine samples for dilute-and-shoot LC-MS/MS toxicology testing without adsorbing target drug analytes.
• Nucleic Acid Recovery - Processes DNA and RNA extracts with minimal nucleic acid adsorption, preserving yield on the hydrophilic PES surface.
