Pall
Acro Disc Syringe Filters w/ Versapor Membrane - 0.45um, 25mm Modified Acrylic Housing, 300/Pk SKU: 4487

Acrylic Copolymer Syringe Filters, 0.45µm, 25mm - 4487

Designed to overcome the limitations of standard membranes, Versapor® technology delivers exceptional strength and flexibility for demanding prefiltration protocols. To ensure consistent results, the hydrophilic Versapor® surface minimizes drug binding, preserving the integrity of critical active ingredients. 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.
