GD/X 25mm Syringe Filter, PES, 0.2um (150 pcs) SKU: 6905-2502

Polyethersulfone (PES) Syringe Filters, 0.2µm, 25mm - 6905-2502

Ensuring the biological integrity of sensitive media begins with reliable filtration, and the Polyethersulfone (PES) Whatman GD/X 25mm Syringe Filter, polyethersulfone filtrationmedium, 0.2µm, 150/pk is engineered to deliver sterile effluents with every use. Driving this efficiency is the integration of a hydrophilic Polyethersulfone (PES) membrane, ensuring high recovery of sensitive samples while maintaining a sterile effluent. Designed to facilitate rapid processing, the housing features an optimized flow geometry that minimizes backpressure, allowing for easier manual filtration even with viscous samples. Consequently, by reducing the risk of downstream contamination, these filters serve as a critical safeguard for the integrity of your experimental results.
