PTFE Membrane, TE Range (TE 37), 1.0um Pore Size, 50mm Circle (50 pcs) SKU: 10411213

PTFE Membrane Filters - 10411213

The Whatman 10411213 combines a controlled pore size distribution with low extractable levels, ensuring the data accuracy that sensitive analytical methods require. A uniform PTFE matrix maintains its rated 1.0 cutoff under the pressures and flow conditions encountered during routine laboratory filtration. In sum, each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• Economical bulk packaging supports laboratories with high consumable throughput where individual sterile wrapping is unnecessary.
• Require pre-wetting with alcohol before filtering aqueous solutions.
• Near-zero extractable levels ensure PTFE membranes contribute no measurable background to mass spectrometry or trace analytical workflows.
• Temperature stability exceeding 260°C makes PTFE the preferred membrane for hot gas sampling and elevated-temperature solvent filtration.
• Excellent for filtering aggressive acids, bases, and non-aqueous solvents.

Reproducible particle counting and size distribution analysis start with a membrane surface that captures particles uniformly — the pore consistency documented above ensures your counts reflect the sample, not random variation in the filter. In this context, because PTFE does not absorb or react with virtually any chemical species, your filtrate composition reflects only the sample itself, eliminating the membrane-derived artifacts that compromise analytical accuracy with reactive matrices. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

Hydrophobic

• Trace Metal Sampling - Used in clean-room environments to filter samples for ICP-MS, ensuring no metallic leachables contaminate the results.
• Aggressive Solvent Prep - Filters extremely corrosive acids and bases in reusable glass holders, offering unmatched chemical inertness in the lab.
• Off-Gas Analysis - Filters exhaust gases from fermentation vessels, protecting analyzers from moisture and foam while passing metabolic gases.
• Aerosol Venting - Acts as a hydrophobic barrier in disc holders, preventing moisture entry while allowing sterile air to pass into tanks.
• Cryogenic Filtration - Retains integrity at sub-zero temperatures, making it ideal for filtering liquid nitrogen or chilled reaction solvents.
• Headspace Analysis - Protects gas chromatography injectors by filtering volatile organic samples without extracting background contaminants.
