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

Polyethersulfone (PES) Syringe Filters, 0.45µm, 13mm - 6782-1304

Streamline your sample preparation workflows with the Polyethersulfone (PES) Whatman Puradisc, 13mm, Syringe Filter, 0.45µm, nonsterile 100/pk, constructed to handle high particulate loads while maintaining rapid throughput. To ensure analytical precision, the unit is constructed with a high-grade Polyethersulfone (PES) membrane providing a consistent 0.45 cutoff that passes only your target analyte. Encasing this critical media is a high-purity polypropylene housing that prevents sample bypass and ensures that every microliter is processed with high fidelity. The result is a filtration solution manufactured in an ISO-certified facility that minimizes distinct interference, providing clean baselines for publication-quality data.
