Nuclepore Hydrophilic Membrane, 0.08um Pore Size, 293 mm Circle, 100/Pk SKU: 10419339

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10419339

Designed to deliver reproducibility and confidence across critical sample types, the Whatman 10419339 provides the filtration consistency that method validation demands. Built for consistent results, quality-controlled manufacturing ensures the filtration medium delivers the retention efficiency and throughput that demanding laboratory protocols require. From raw polymer through final inspection, the manufacturing process is designed to ensure that every membrane disc meets the performance specifications of its grade designation.

Material Specifications

• Manufactured with tight pore size control for precise separation of cells and particulates.
• Uniform pore density across the membrane surface ensures representative sampling for environmental and biological particulate analysis.
• Optically clear construction enables direct on-membrane visualization of captured particles without transfer or additional preparation.
• Offer a smooth, flat glass-like surface specifically designed for microscopy analysis.
• Bulk packaging format provides cost-effective access for high-volume laboratories performing non-critical filtration and sample preparation.

Scaling your method from development to routine production requires membrane consistency at every lot — the documented specifications of these membranes provide the reproducibility needed to validate the filtration step once. For this application, defined pore geometry gives you a membrane that functions as a precision sieve, capturing particles strictly by size rather than the impaction and diffusion mechanisms that depth filters rely on. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Hydrophilic

• Exosome Isolation - Separates extracellular vesicles from larger cell debris using defined pore sizes, preventing contamination in RNA analysis.
• Erythrocyte Deformability - Mimics capillary dimensions to test red blood cell flexibility and rheology in clinical hemorheology research.
• Legionella Recovery - Captures bacteria from hot water samples on a flat plane for direct fluorescent antibody staining and microscope counting.
• Liposome Sizing - Used in extrusion devices to force lipid suspensions through exact pores, creating uniform unilamellar vesicles for drug delivery.
• Oceanographic Sampling - Fractionates plankton populations by size in seawater, ensuring precise separation for biomass and diversity studies.
• Asbestos Analysis - Provides a smooth, flat surface for collecting airborne fibers, allowing for direct counting via phase-contrast light microscopy.
