GD/X 25mm Syringe Filter, PES, 0.45um (150 pcs) SKU: 6905-2504

Polyethersulfone (PES) Syringe Filters, 0.45µm, 25mm - 6905-2504

In high-throughput analytical laboratories, the Polyethersulfone (PES) Whatman GD/X 25mm Syringe Filter, polyethersulfone filtrationmedium, 0.45µm, 150/pk series establishes a standard for effective particulate removal and sample clarification. Facilitating rapid sample turnover, the hydrophilic Polyethersulfone (PES) membrane structure ensures the 0.45 rating remains consistent even under pressure. Designed to facilitate rapid processing, the housing features an optimized flow geometry that minimizes backpressure, allowing for easier manual filtration even with viscous samples. Meeting the needs of regulated environments, this series supports compliance with stringent purity protocols across pharmaceutical and environmental applications.
