Whatman
GD/X 25mm Syringe Filter, PES, 0.45um (150 pcs) SKU: 6876-2504

Polyethersulfone (PES) Syringe Filters, 0.45µm, 25mm - 6876-2504

For researchers requiring consistent baselines in HPLC and dissolution testing, the Polyethersulfone (PES) Whatman GD/X 25mm Syringe Filter, polyethersulfone filtrationmedium, 0.45µm, 150/pk offers a robust solution for extending instrument life. At the core of the device is a uniform Polyethersulfone (PES) matrix, delivering high dirt-loading capacity and reliable exclusion of interfering particles. Complementing the membrane's purity, the housing's thermal bonding eliminates the need for adhesives, removing a common source of extractable contamination. The result is a filtration solution manufactured in an ISO-certified facility that minimizes distinct interference, providing clean baselines for publication-quality data.
