wwPTFE Membrane Disc Filter - 0.45um, 50mm, 50/Pk SKU: 60550

Water-Wettable PTFE Membrane Filters - 60550

Precision-manufactured Hydrophilic membrane with a verified 0.45 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. On the performance side, thermal stability of the PTFE base material supports filtration of heated solvents and process fluids without pore distortion or dimensional change. Accordingly, controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

• Near-zero extractable levels protect analytical sensitivity in HPLC sample preparation and trace-level chemical analysis where background interference is critical.
• Filters both aqueous and organic samples interchangeably without membrane changes, simplifying workflows that process mixed-polarity sample sets.
• Rated for continuous operation at temperatures reaching 55°C, enabling filtration of heated solvents and process fluids without material compromise.
• Economical bulk packaging supports laboratories with high consumable throughput where individual sterile wrapping is unnecessary.
• Permanently modified hydrophilic surface maintains wettability throughout the membrane lifetime without surfactant additives that could leach into the filtrate.

Whether your method calls for gravimetric analysis, particle visualization, or microbial enumeration, the pore consistency documented above ensures your results reflect the sample, not the filter. The documented retention specifications of this device ensure that your filtrate meets the particulate cleanliness requirements of your downstream analytical or process step without additional verification. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
