PTFE Membrane Filters, 5.00 um, 90mm, Nonsterile, 50/Pk SKU: SF13872

Polytetrafluoroethylene (PTFE) Membrane Filters, 5.0µm, 90mm - SF13872

Designed to protect sensitive chromatography columns from clogging, the Polytetrafluoroethylene (PTFE) Membrane Filters, 5.0um, 90mm, Nonsterile, 50/pk delivers exceptional retention of particulates without compromising flow rates. To ensure analytical precision, the unit is constructed with a high-grade Polytetrafluoroethylene (PTFE) membrane providing a consistent 5.0 cutoff that passes only your target analyte. To ensure experimental consistency, the high-quality material provides uniform flow and predictable retention rates across the entire surface area. 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 5.0 retention rating for clarification

When you integrate these filters into your daily standard operating procedures, you are choosing a workflow that prioritizes efficiency without compromising results. 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.
