PTFE Hydrophilic Membrane Filters, 0.22 um, 25mm, Nonsterile, 200/Pk SKU: SF13840

Polytetrafluoroethylene (PTFE) Membrane Filters, 0.22µm, 25mm - SF13840

For critical applications requiring absolute sterility assurance, the Polytetrafluoroethylene (PTFE) Hydrophilic Membrane Filters, 0.22um, 25mm, Nonsterile, 200/pk series provides a verified barrier against bacterial contamination. Central to this performance is a hydrophobic Polytetrafluoroethylene (PTFE) membrane with a precise 0.22 pore structure that ensures the complete removal of bacteria and fine particulates. Further enhancing usability, the robust physical structure of the membrane allows for easy handling and placement into filtration hardware without tearing. 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
• 0.22 rating suitable for sterile filtration

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. 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.
