PTFE Membrane Filters, 5.00 um, 47mm, Nonsterile, 100/Pk SKU: SF13871

PTFE Membrane Filters - SF13871

Designed to deliver reproducibility and confidence across critical sample types, the Tisch SF13871 provides the filtration consistency that method validation demands. Equally important, quality-controlled manufacturing ensures the filtration medium delivers the retention efficiency and throughput that demanding laboratory protocols require. Taken together, consistent surface properties across the full membrane area support uniform particle capture and reliable results in gravimetric, microscopic, and culture-based analytical workflows.

Material Specifications

• Supplied in bulk non-sterile packaging, offering an economical option for routine clarification and general laboratory filtration tasks.
• 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.
• Temperature stability exceeding 260°C makes PTFE the preferred membrane for hot gas sampling and elevated-temperature solvent filtration.

Scaling from development to routine production requires membrane consistency at every lot, and the documented specifications provide the reproducibility needed to validate the filtration step once. To address this, 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. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

Hydrophobic

• PM2.5 Air Monitoring - The regulatory standard for weighing fine air particulates, ensuring minimal moisture absorption affects the final mass.
• 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.
• Cryogenic Filtration - Retains integrity at sub-zero temperatures, making it ideal for filtering liquid nitrogen or chilled reaction solvents.
• 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.
