Nuclepore Hydrophilic Membrane, 0.1um Pore Size, 25mm Circle, 100/Pk SKU: 10419506

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10419506

The Whatman 10419506 combines a controlled pore size distribution with low extractable levels, ensuring the data accuracy that sensitive analytical methods require. Equally important, precision-manufactured Hydrophilic membrane with a verified 0.1 pore structure delivers consistent retention across the full operating range. Altogether, precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

• Offer a smooth, flat glass-like surface specifically designed for microscopy analysis.
• Low protein binding and biologically inert surface properties make track-etched Polycarbonate compatible with cell biology and cytology workflows.
• Optically clear construction enables direct on-membrane visualization of captured particles without transfer or additional preparation.
• Economical bulk packaging supports laboratories with high consumable throughput where individual sterile wrapping is unnecessary.
• Uniform pore density across the membrane surface ensures representative sampling for environmental and biological particulate analysis.

Microbial enumeration methods require complete retention at the rated pore size and a surface that supports colony growth without inhibition, and the membrane specifications above confirm both requirements for your culture-based workflows. The precisely etched, cylindrical pores of track-etched polycarbonate provide the sharpest size cutoff of any polymeric membrane, giving you near-absolute retention at the rated pore diameter for applications where size-selective capture is critical. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Wettability

Hydrophilic

• Chemotaxis Migration - Acts as a precise barrier in Boyden chambers to measure cell migration towards chemoattractants without passive diffusion.
• Exosome Isolation - Separates extracellular vesicles from larger cell debris using defined pore sizes, preventing contamination in RNA analysis.
• Asbestos Analysis - Provides a smooth, flat surface for collecting airborne fibers, allowing for direct counting via phase-contrast light microscopy.
• Erythrocyte Deformability - Mimics capillary dimensions to test red blood cell flexibility and rheology in clinical hemorheology research.
• Oceanographic Sampling - Fractionates plankton populations by size in seawater, ensuring precise separation for biomass and diversity studies.
• Liposome Sizing - Used in extrusion devices to force lipid suspensions through exact pores, creating uniform unilamellar vesicles for drug delivery.
