Acro Disc Syringe Filters w/ PVDF Membrane - 0.45um, 13mm, Male Slip Luer Outlet, 300/Pk SKU: 4457

Polyvinylidene Difluoride (PVDF) Syringe Filters, 0.45µm, 13mm - 4457

Designed to protect sensitive chromatography columns from clogging, the Polyvinylidene Difluoride (PVDF) Syringe Filters delivers exceptional retention of particulates without compromising flow rates. Driving this clarification performance is a hydrophilic Polyvinylidene Difluoride (PVDF) membrane featuring a verified 0.45 pore structure that captures target particulates while minimizing holdup volume. Designed to facilitate rapid processing, the housing features an optimized flow geometry that minimizes backpressure, allowing for easier manual filtration even with viscous samples. Ultimately, this rigorous attention to manufacturing quality ensures batch-to-batch reproducibility, allowing laboratories to standardize their workflows with total confidence.
