PTFE Membrane Filters, 0.45um, 25mm, Nonsterile, 200/Pk SKU: SF13860

Polytetrafluoroethylene (PTFE) Membrane Filters, 0.45µm, 25mm - SF13860

Streamline your sample preparation workflows with the Polytetrafluoroethylene (PTFE) Membrane Filters, 0.45um, 25mm, Nonsterile, 200/pk, constructed to handle high particulate loads while maintaining rapid throughput. 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. Delivered as precision-cut discs, these membranes ensure compatibility with all standard filter holders and funnels. The result is a filtration solution manufactured in an ISO-certified facility that minimizes distinct interference, providing clean baselines for publication-quality data.

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

By selecting a filter that matches the exact chemical nature of your samples, you ensure that your workflow remains uninterrupted by membrane failures. Protecting your downstream processes requires a defensive strategy, and utilizing these verified filters gives you the peace of mind that your work is safe. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
