PTFE Membrane Filters, 0.22 um, 142mm, Nonsterile, 50/Pk SKU: SF15130

Polytetrafluoroethylene (PTFE) Membrane Filters, 0.22µm, 142mm - SF15130

Eliminate the risk of microbial contamination in your upstream workflows with the Polytetrafluoroethylene (PTFE) Membrane Filters, 0.22um, 142mm, Nonsterile, 25/pk, optimized for sterile filtration protocols. 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. 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
• 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. 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.
