PTFE Membrane, WTP Range, 0.2um Pore Size, 25mm Circle (100 pcs) SKU: 7582-002

PTFE Membrane Filters - 7582-002

Precision-manufactured Hydrophobic membrane with a verified 0.2 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Precision-manufactured Hydrophobic membrane with a verified 0.2 pore structure delivers consistent retention across the full operating range. Accordingly, precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

• 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.
• Permanently hydrophobic and chemically inert, PTFE resists degradation from virtually every solvent, acid, and base encountered in laboratory applications.
• Bulk format reduces per-unit packaging waste and cost, appropriate for routine particulate removal and clarification where aseptic handling is not specified.
• Temperature stability exceeding 260°C makes PTFE the preferred membrane for hot gas sampling and elevated-temperature solvent filtration.

Multi-site studies where different laboratories must produce comparable data benefit from membranes manufactured to tight specifications, giving you confidence that site-to-site variability is not introduced by the filtration step. PTFE's thermal stability across a wide operating range means you can filter hot solvents and process elevated-temperature samples without the membrane softening or pore distortion that limits thermoplastic alternatives. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

Hydrophobic

• Aerosol Venting - Acts as a hydrophobic barrier in disc holders, preventing moisture entry while allowing sterile air to pass into tanks.
• Aggressive Solvent Prep - Filters extremely corrosive acids and bases in reusable glass holders, offering unmatched chemical inertness in the lab.
• Bio-fluid Degassing - Allows gas to escape from microfluidic channels while retaining aqueous liquids, preventing air locks in the system.
• Off-Gas Analysis - Filters exhaust gases from fermentation vessels, protecting analyzers from moisture and foam while passing metabolic gases.
• PM2.5 Air Monitoring - The regulatory standard for weighing fine air particulates, ensuring minimal moisture absorption affects the final mass.
• Trace Metal Sampling - Used in clean-room environments to filter samples for ICP-MS, ensuring no metallic leachables contaminate the results.
