Nuclepore Hydrophilic Membrane, 5.0um Pore Size, 47mm Circle, 100/Pk SKU: 10417412

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10417412

Designed to deliver reproducibility and confidence across critical sample types, the Whatman 10417412 provides the filtration consistency that method validation demands. Optimized for laboratory use, reproducible separation characteristics define the membrane structure, protecting downstream instruments and preserving sample integrity throughout the filtration process. Controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

• Low protein binding and biologically inert surface properties make track-etched Polycarbonate compatible with cell biology and cytology workflows.
• Track-etched Polycarbonate membranes feature perfectly cylindrical pores for absolute fractionation.
• Optically clear construction enables direct on-membrane visualization of captured particles without transfer or additional preparation.
• Bulk packaging format provides cost-effective access for high-volume laboratories performing non-critical filtration and sample preparation.
• Uniform pore density across the membrane surface ensures representative sampling for environmental and biological particulate analysis.

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. To address this, polycarbonate's optical clarity when wet allows direct on-membrane visualization without clearing or staining steps, streamlining your microscopy workflow and reducing the sample preparation time between filtration and analysis. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

Wettability

Hydrophilic

• Exosome Isolation - Separates extracellular vesicles from larger cell debris using defined pore sizes, preventing contamination in RNA analysis.
• Legionella Recovery - Captures bacteria from hot water samples on a flat plane for direct fluorescent antibody staining and microscope counting.
• Chemotaxis Migration - Acts as a precise barrier in Boyden chambers to measure cell migration towards chemoattractants without passive diffusion.
• 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.
• Erythrocyte Deformability - Mimics capillary dimensions to test red blood cell flexibility and rheology in clinical hemorheology research.
