PTFE Membrane Filters, 0.45um, 90mm, Nonsterile, 50/Pk SKU: SF13862

Polytetrafluoroethylene (PTFE) Membrane Filters, 0.45µm, 90mm - SF13862

Reducing background noise in analytical assays begins with proper clarification, and the Polytetrafluoroethylene (PTFE) Membrane Filters, 0.45um, 90mm, Nonsterile, 50/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. Manufactured with strict thickness tolerances, these membranes provide a reliable barrier for critical filtration steps without compromising flow. Consequently, by reducing the risk of downstream contamination, these filters serve as a critical safeguard for the integrity of your experimental results.

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

Your laboratory throughput depends on reliable consumables, and these filters are designed to keep your sequences running smoothly, sample after sample. Protecting your downstream processes requires a defensive strategy, and utilizing these verified filters gives you the peace of mind that your work is safe. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
