Polytetrafluoroethylene (PTFE) Membrane Filters, 0.22µm, 90mm - SF13857

Designed for the stringent demands of cell culture and biological assays, the Polytetrafluoroethylene (PTFE) Membrane Filters, 0.22um, 90mm, Nonsterile, 50/pk offers validated bacterial retention for confident sample preparation. Leveraging the specific retention properties of Polytetrafluoroethylene (PTFE), this device offers a validated 0.22 barrier against microbial contaminants. 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

You can streamline your sample preparation process significantly by adopting a filtration solution designed to handle your specific volume requirements. You can rely on the certified integrity of these units to protect your critical samples and instrumentation from damaging contaminants. 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.
