PTFE Hydrophilic Membrane Filters, 0.45um, 90mm, Nonsterile, 50/Pk SKU: SF13847

Polytetrafluoroethylene (PTFE) Membrane Filters, 0.45µm, 90mm - SF13847

For researchers requiring consistent baselines in HPLC and dissolution testing, the Polytetrafluoroethylene (PTFE) Hydrophilic Membrane Filters, 0.45um, 90mm, Nonsterile, 50/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. Manufactured with strict thickness tolerances, these membranes provide a reliable barrier for critical filtration steps without compromising flow. 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
• N/A (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 invest significant resources into your samples; safeguarding them with a proven filtration barrier is a cost-effective insurance policy for your lab. 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.
