PTFE Membrane Filters, 0.22 um, 50mm, Nonsterile, 100/Pk SKU: SF14684

Polytetrafluoroethylene (PTFE) Membrane Filters, 0.22µm, 50mm - SF14684

Ensuring the biological integrity of sensitive media begins with reliable filtration, and the Polytetrafluoroethylene (PTFE) Membrane Filters, 0.22um, 50mm, Nonsterile, 100/pk is engineered to deliver sterile effluents with every use. Driving this efficiency is the integration of a hydrophobic Polytetrafluoroethylene (PTFE) membrane, ensuring high recovery of sensitive samples while maintaining a sterile effluent. Delivered as precision-cut discs, these membranes ensure compatibility with all standard filter holders and funnels. 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

Your laboratory throughput depends on reliable consumables, and these filters are designed to keep your sequences running smoothly, sample after sample. You can rely on the certified integrity of these units to protect your critical samples and instrumentation from damaging contaminants. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
