PTFE Membrane Filters, No Support Layer, 2.0um, 37mm, 100/Pk SKU: SPEC20237

PTFE Membrane Filters - SPEC20237

Precision-manufactured hydrophobic membrane with a verified 2.0 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Moreover, precision-manufactured hydrophobic membrane with a verified 2.0 pore structure delivers consistent retention across the full operating range. Working in concert, each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• Near-zero extractable levels ensure PTFE membranes contribute no measurable background to mass spectrometry or trace analytical workflows.
• Non-wetting surface chemistry maintains gas permeability while excluding liquid intrusion, critical for sterile venting and pressure equalization.
• Bulk format reduces per-unit packaging waste and cost, appropriate for routine particulate removal and clarification where aseptic handling is not specified.
• Thermal stability of the membrane material allows safe operation at temperatures up to 120°C without degradation of retention characteristics or dimensional integrity.
• Unmatched solvent resistance allows PTFE to process chlorinated hydrocarbons, ketones, and strong oxidizers that destroy other membrane chemistries.

Maintaining accreditation under ISO 17025 or similar quality frameworks requires documented traceability at every step — the specification compliance of each membrane lot supports your ongoing audit readiness. 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. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

Hydrophobic

• 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.
• Off-Gas Analysis - Filters exhaust gases from fermentation vessels, protecting analyzers from moisture and foam while passing metabolic gases.
• Headspace Analysis - Protects gas chromatography injectors by filtering volatile organic samples without extracting background contaminants.
• Bio-fluid Degassing - Allows gas to escape from microfluidic channels while retaining aqueous liquids, preventing air locks in the system.
• Cryogenic Filtration - Retains integrity at sub-zero temperatures, making it ideal for filtering liquid nitrogen or chilled reaction solvents.
