PTFE Hydrophilic Membrane Filters, 0.22 um, 90mm, Nonsterile, 100/Pk SKU: SF13842

Polytetrafluoroethylene (PTFE) Membrane Filters, 0.22µm, 90mm - SF13842

For critical applications requiring absolute sterility assurance, the Polytetrafluoroethylene (PTFE) Hydrophilic Membrane Filters, 0.22um, 90mm, Nonsterile, 50/pk series provides a verified barrier against bacterial contamination. To achieve this medical-grade standard, the filter utilizes a Polytetrafluoroethylene (PTFE) membrane that provides a sharp 0.22 cutoff necessary for sterilizing biological fluids. Manufactured with strict thickness tolerances, these membranes provide a reliable barrier for critical filtration steps without compromising flow. Meeting the needs of regulated environments, this series supports compliance with stringent purity protocols across pharmaceutical and environmental applications.

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. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
