PTFE Membrane Filters, 0.1um, 47mm, Nonsterile, 200/Pk SKU: SF15120

PTFE Membrane Filters - SF15120

Designed to deliver reproducibility and confidence across critical sample types, the Tisch SF15120 provides the filtration consistency that method validation demands. Quality-controlled manufacturing ensures the filtration medium delivers the retention efficiency and throughput that demanding laboratory protocols require. With this in mind, 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.
• 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.
• Require pre-wetting with alcohol before filtering aqueous solutions.
• Unmatched solvent resistance allows PTFE to process chlorinated hydrocarbons, ketones, and strong oxidizers that destroy other membrane chemistries.

Environmental monitoring programs where sample-to-sample comparability determines trend validity benefit directly from the lot-level consistency of these membranes, removing the filter as a variable in your long-term data sets. 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.

Wettability

Hydrophobic

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