Tisch
PTFE Membrane Filters, 1.0um, 47mm, Nonsterile, 100/Pk SKU: SF13866

PTFE Membrane Filters - SF13866

Designed to deliver reproducibility and confidence across critical sample types, the Tisch SF13866 provides the filtration consistency that method validation demands. Manufactured to exacting specifications, reproducible separation characteristics define the membrane structure, protecting downstream instruments and preserving sample integrity throughout the filtration process. Working in concert, lot-level verification of pore size, flow rate, and physical dimensions ensures that membrane performance remains predictable when scaling from method development to routine analysis.

Material Specifications

• Excellent for filtering aggressive acids, bases, and non-aqueous solvents.
• Bulk format reduces per-unit packaging waste and cost, appropriate for routine particulate removal and clarification where aseptic handling is not specified.
• Permanently hydrophobic and chemically inert, PTFE resists degradation from virtually every solvent, acid, and base encountered in laboratory applications.
• Hydrophobic membrane surface provides a reliable barrier for air venting and gas filtration, preventing aqueous breakthrough under normal operating conditions.
• Thermal stability of the membrane material allows safe operation at temperatures up to 120°C without degradation of retention characteristics or dimensional integrity.

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. The inherently hydrophobic surface provides a natural barrier for air and gas venting, allowing you to protect equipment without pre-conditioning the membrane. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Hydrophobic

• Aggressive Solvent Prep - Filters extremely corrosive acids and bases in reusable glass holders, offering unmatched chemical inertness in the lab.
• PM2.5 Air Monitoring - The regulatory standard for weighing fine air particulates, ensuring minimal moisture absorption affects the final mass.
• Cryogenic Filtration - Retains integrity at sub-zero temperatures, making it ideal for filtering liquid nitrogen or chilled reaction solvents.
• 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.
• Trace Metal Sampling - Used in clean-room environments to filter samples for ICP-MS, ensuring no metallic leachables contaminate the results.
