PTFE Hydrophilic Membrane Filters, 0.45um, 25mm, Nonsterile, 200/Pk SKU: SF13845

Polytetrafluoroethylene (PTFE) Membrane Filters, 0.45µm, 25mm - SF13845

Reducing background noise in analytical assays begins with proper clarification, and the Polytetrafluoroethylene (PTFE) Hydrophilic Membrane Filters, 0.45um, 25mm, 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. 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
• Verified 0.45 retention rating for clarification

You can streamline your sample preparation process significantly by adopting a filtration solution designed to handle your specific volume requirements. You invest significant resources into your samples; safeguarding them with a proven filtration barrier is a cost-effective insurance policy for your lab. 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.
