PTFE Membrane Filters - 10411211
Designed to deliver reproducibility and confidence across critical sample types, the Whatman 10411211 provides the filtration consistency that method validation demands. Manufactured to exacting specifications, verified 1.0 pore distribution across the Hydrophobic membrane surface guarantees batch-to-batch consistency in particle capture and analyte passage. Each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.
Material Specifications
- Non-sterile configuration is suited for analytical sample preparation, mobile phase filtration, and other workflows where pre-sterilization is not required.
- 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.
- Near-zero extractable levels ensure PTFE membranes contribute no measurable background to mass spectrometry or trace analytical workflows.
- Unmatched solvent resistance allows PTFE to process chlorinated hydrocarbons, ketones, and strong oxidizers that destroy other membrane chemistries.
Reporting filtration parameters alongside your analytical results demands documented pore size, material chemistry, and lot traceability — the membrane specifications above provide the specificity that reviewers and auditors expect. For this purpose, universal chemical resistance makes PTFE the membrane you reach for when your sample matrix would dissolve any other filter medium — strong acids, aggressive solvents, and oxidizers pass through without affecting integrity. 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.

- Aggressive Solvent Prep - Filters extremely corrosive acids and bases in reusable glass holders, offering unmatched chemical inertness in the lab.
- Cryogenic Filtration - Retains integrity at sub-zero temperatures, making it ideal for filtering liquid nitrogen or chilled reaction solvents.
- 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.
- Aerosol Venting - Acts as a hydrophobic barrier in disc holders, preventing moisture entry while allowing sterile air to pass into tanks.
- PM2.5 Air Monitoring - The regulatory standard for weighing fine air particulates, ensuring minimal moisture absorption affects the final mass.
