PTFE Membrane Filters, 0.1um, 142mm, Nonsterile, 25/Pk SKU: SF18063

PTFE Membrane Filters - SF18063

Precision-manufactured hydrophilic membrane with a verified 0.1 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Optimized for laboratory use, a uniform PTFE matrix maintains its rated 0.1 cutoff under the pressures and flow conditions encountered during routine laboratory filtration. Consequently, each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• Bulk format reduces per-unit packaging waste and cost, appropriate for routine particulate removal and clarification where aseptic handling is not specified.
• Maximum operating temperature of 120°C accommodates warm sample filtration and elevated-temperature processes that exceed the limits of standard devices.
• Temperature stability exceeding 260°C makes PTFE the preferred membrane for hot gas sampling and elevated-temperature solvent filtration.
• Require pre-wetting with alcohol before filtering aqueous solutions.
• Hydrophilic surface chemistry promotes rapid and uniform wetting across the full membrane area, delivering consistent flow from the first drop.

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. Here, for aggressive solvent recovery and waste stream filtration, PTFE's inertness allows you to reclaim expensive solvents through filtration without introducing extractable contamination from the filter medium into your recovered material. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

• PM2.5 Air Monitoring - The regulatory standard for weighing fine air particulates, ensuring minimal moisture absorption affects the final mass.
• Headspace Analysis - Protects gas chromatography injectors by filtering volatile organic samples without extracting background contaminants.
• 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.
• 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.
