Pall
Acro Disc Syringe Filters w/ Fluorodyne II Membrane Optim. for Scale Up, 25mm 0.2um , Sterile, 50/Pk SKU: 4907-N

Hydrophilic PVDF (Fluorodyne II) Syringe Filters, 0.2µm, 25mm - 4907-N

Designed to maximize yield, the Fluorodyne® Syringe Filters ensures that preservatives and active pharmaceutical ingredients pass through without adsorption. Driving this sterile efficiency is a high-flow structure that permits rapid processing of ophthalmics without pre-wetting or protein loss. Encasing this critical media is a high-purity polypropylene housing that prevents sample bypass and ensures that every microliter is processed with high fidelity. Ultimately, this rigorous attention to manufacturing quality ensures batch-to-batch reproducibility, allowing laboratories to standardize their workflows with total confidence.
