PTFE Membrane Filters, 5.00 um, 37mm, Nonsterile, 100/Pk SKU: SF17382

PTFE Membrane Filters - SF17382

Precision-manufactured hydrophobic membrane with a verified 5.0 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Quality-controlled manufacturing ensures the filtration medium delivers the retention efficiency and throughput that demanding laboratory protocols require. As designed, lot-level verification of pore size, flow rate, and physical dimensions ensures that membrane performance remains predictable when scaling from method development to routine analysis.

Material Specifications

• Temperature rating of 120°C provides the thermal headroom required for warm sample processing, heated media preparation, and elevated-temperature analytical methods.
• Water-repellent membrane surface sustains airflow in venting applications while providing a defined barrier against liquid passage.
• Permanently hydrophobic and chemically inert, PTFE resists degradation from virtually every solvent, acid, and base encountered in laboratory applications.
• Near-zero extractable levels ensure PTFE membranes contribute no measurable background to mass spectrometry or trace analytical workflows.
• Excellent for filtering aggressive acids, bases, and non-aqueous solvents.

If your protocol requires direct on-membrane analysis by microscopy or culture, the surface characteristics and dimensional tolerances described above give you a substrate that performs consistently from disc to disc. For applications like these, the non-stick surface of PTFE minimizes sample adhesion during filtration, improving your recovery of viscous or high-value samples where every microliter of filtrate matters to downstream yield calculations. 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.

Hydrophobic

• Bio-fluid Degassing - Allows gas to escape from microfluidic channels while retaining aqueous liquids, preventing air locks in the system.
• Trace Metal Sampling - Used in clean-room environments to filter samples for ICP-MS, ensuring no metallic leachables contaminate the results.
• Headspace Analysis - Protects gas chromatography injectors by filtering volatile organic samples without extracting background contaminants.
• Off-Gas Analysis - Filters exhaust gases from fermentation vessels, protecting analyzers from moisture and foam while passing metabolic gases.
• Cryogenic Filtration - Retains integrity at sub-zero temperatures, making it ideal for filtering liquid nitrogen or chilled reaction solvents.
• Aggressive Solvent Prep - Filters extremely corrosive acids and bases in reusable glass holders, offering unmatched chemical inertness in the lab.
