PTFE Membrane Filters, 0.45um, 47mm, Nonsterile, 200/Pk SKU: SF13861

Polytetrafluoroethylene (PTFE) Membrane Filters, 0.45µm, 47mm - SF13861

Reducing background noise in analytical assays begins with proper clarification, and the Polytetrafluoroethylene (PTFE) Membrane Filters, 0.45um, 47mm, Nonsterile, 200/pk is engineered to remove interfering solids efficiently. To ensure analytical precision, the unit is constructed with a high-grade Polytetrafluoroethylene (PTFE) membrane providing a consistent 0.45 cutoff that passes only your target analyte. Further enhancing usability, the robust physical structure of the membrane allows for easy handling and placement into filtration hardware without tearing. Ultimately, this rigorous attention to manufacturing quality ensures batch-to-batch reproducibility, allowing laboratories to standardize their workflows with total confidence.

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
• Verified 0.45 retention rating for clarification

By selecting a filter that matches the exact chemical nature of your samples, you ensure that your workflow remains uninterrupted by membrane failures. Trust in the consistent performance of your filtration step to remove the variables that often lead to costly re-runs and ambiguous data. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
