Acro Disc Syringe Filters w/ PTFE Membrane - 1um, 25mm, 1000/Pk SKU: 4503

Polytetrafluoroethylene (PTFE) Syringe Filters, 1µm, 25mm - 4503

Reducing background noise in analytical assays begins with proper clarification, and the Polytetrafluoroethylene (PTFE) Syringe Filters is engineered to remove interfering solids efficiently. To ensure analytical precision, the unit is constructed with a high-grade Polytetrafluoroethylene (PTFE) membrane providing a consistent 1 cutoff that passes only your target analyte. Encasing this critical media is a high-purity polypropylene housing that prevents sample bypass and ensures that every microliter is processed with high fidelity. The result is a filtration solution manufactured in an ISO-certified facility that minimizes distinct interference, providing clean baselines for publication-quality data.
