PTFE Membrane Filters, 0.45um, 142mm, Nonsterile, 50/Pk SKU: SF15131

Polytetrafluoroethylene (PTFE) Membrane Filters, 0.45µm, 142mm - SF15131

For researchers requiring consistent baselines in HPLC and dissolution testing, the Polytetrafluoroethylene (PTFE) Membrane Filters, 0.45um, 142mm, Nonsterile, 25/pk offers a robust solution for extending instrument life. Driving this clarification performance is a hydrophobic Polytetrafluoroethylene (PTFE) membrane featuring a verified 0.45 pore structure that captures target particulates while minimizing holdup volume. Further enhancing usability, the robust physical structure of the membrane allows for easy handling and placement into filtration hardware without tearing. Ultimately, this rigorous attention to manufacturing quality ensures batch-to-batch reproducibility, allowing laboratories to standardize their workflows with total confidence.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Polytetrafluoroethylene (PTFE) membrane with hydrophobic (standard) / hydrophilic (treated) affinity
• Chemically Inert Characteristics
• Universal resistance to aggressive organic solvents, strong acids, and alkalis
• Hydrophobic version requires alcohol pre-wetting for aqueous solutions
• Verified 0.45 retention rating for clarification

Your laboratory throughput depends on reliable consumables, and these filters are designed to keep your sequences running smoothly, sample after sample. You can rely on the certified integrity of these units to protect your critical samples and instrumentation from damaging contaminants. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.
