PTFE Membrane Filters, 0.22 um, 150mm, Nonsterile, 50/Pk SKU: SF13858

Polytetrafluoroethylene (PTFE) Membrane Filters, 0.22µm, 150mm - SF13858

When sample purity is non-negotiable, the Polytetrafluoroethylene (PTFE) Membrane Filters, 0.22um, 150mm, Nonsterile, 25/pk serves as a reliable safeguard, effectively removing microorganisms from aqueous solutions. 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

When you integrate these filters into your daily standard operating procedures, you are choosing a workflow that prioritizes efficiency without compromising results. 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.
