PTFE Hydrophilic Membrane Filters, 0.22 um, 47mm, Nonsterile, 200/Pk SKU: SF13841

Polytetrafluoroethylene (PTFE) Membrane Filters, 0.22µm, 47mm - SF13841

When sample purity is non-negotiable, the Polytetrafluoroethylene (PTFE) Hydrophilic Membrane Filters, 0.22um, 47mm, Nonsterile, 200/pk serves as a reliable safeguard, effectively removing microorganisms from aqueous solutions. Leveraging the specific retention properties of Polytetrafluoroethylene (PTFE), this device offers a validated 0.22 barrier against microbial contaminants. 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. You can rely on the certified integrity of these units to protect your critical samples and instrumentation from damaging contaminants. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
