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

Polytetrafluoroethylene (PTFE) Membrane Filters, 5.0µm, 47mm - SF13871

Designed to protect sensitive chromatography columns from clogging, the Polytetrafluoroethylene (PTFE) Membrane Filters deliver exceptional retention of particulates without compromising flow rates. At the core of the device is a uniform Polytetrafluoroethylene (PTFE) matrix, delivering high dirt-loading capacity and reliable exclusion of interfering particles. Manufactured with strict thickness tolerances, these membranes provide a reliable barrier for critical filtration steps without compromising flow. Ultimately, this rigorous attention to manufacturing quality ensures batch-to-batch reproducibility, allowing laboratories to standardize their workflows with total confidence.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Polytetrafluoroethylene (PTFE) membrane with hydrophobic (standard) / hydrophilic (treated) affinity
• Chemically Inert characteristics
• Universal resistance to aggressive organic solvents, strong acids, and alkalis
• Hydrophobic version requires alcohol pre-wetting for aqueous solutions
• Verified 5.0 retention rating for clarification

You can streamline your sample preparation process significantly by adopting a filtration solution designed to handle your specific volume requirements. Protecting your downstream processes requires a defensive strategy, and utilizing these verified filters gives you the peace of mind that your work is safe. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.
