Acro Disc One Syringe Filters w/ wwPTFE Membrane - GxF/0.2um, 25mm, 1000/Pk SKU: AP-4915

Hydrophilic PTFE (wwPTFE) Syringe Filters, 0.2µm, 25mm - AP-4915

Simplify your laboratory inventory with the Hydrophilic PTFE (wwPTFE) Syringe Filters, a truly universal filter capable of handling aggressive solvents and water-based samples alike. To dissolve the barrier between aqueous and organic workflows, the hydrophilic PTFE structure wets immediately without the need for alcohol flushing. 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.
