PTFE Membrane Filters, 0.22 um, 47mm, Nonsterile, 100/Pk SKU: SF13856

Polytetrafluoroethylene (PTFE) Membrane Filters, 0.22µm, 47mm - SF13856

Designed for the stringent demands of cell culture and biological assays, the Polytetrafluoroethylene (PTFE) Membrane Filters, 0.22um, 47mm, Nonsterile, 100/pk offers validated bacterial retention for confident sample preparation. Driving this efficiency is the integration of a hydrophobic Polytetrafluoroethylene (PTFE) membrane, ensuring high recovery of sensitive samples while maintaining a sterile effluent. To ensure experimental consistency, the high-quality material provides uniform flow and predictable retention rates across the entire surface area. 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

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.
