PTFE Membrane Filters, 0.22 um, 25mm, Nonsterile, 200/Pk SKU: SF13855

Polytetrafluoroethylene (PTFE) Membrane Filters, 0.22µm, 25mm - SF13855

Designed for the stringent demands of cell culture and biological assays, the Polytetrafluoroethylene (PTFE) Membrane Filters, 0.22um, 25mm, Nonsterile, 200/pk offers validated bacterial retention for confident sample preparation. 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. To ensure experimental consistency, the high-quality material provides uniform flow and predictable retention rates across the entire surface area. 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. Trust in the consistent performance of your filtration step to remove the variables that often lead to costly re-runs and ambiguous data. 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.
