PTFE Membrane Filters (w/out Substrate), 5.00 um, 90mm, Nonsterile, 100/Pk SKU: SF18124

Polytetrafluoroethylene (PTFE) Membrane Filters, 5.0µm, 90mm - SF18124

Streamline your sample preparation workflows with the Polytetrafluoroethylene (PTFE) Membrane Filters, constructed to handle high particulate loads while maintaining rapid throughput. 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

By selecting a filter that matches the exact chemical nature of your samples, you ensure that your workflow remains uninterrupted by membrane failures. You invest significant resources into your samples; safeguarding them with a proven filtration barrier is a cost-effective insurance policy for your lab. 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.
