Nuclepore Hydrophilic Membrane, 0.1um Pore Size, 47mm Circle, 100/Pk SKU: 10419512

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10419512

The Whatman 10419512 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. Verified 0.1 pore distribution across the Hydrophilic membrane surface guarantees batch-to-batch consistency in particle capture and analyte passage. In practice, precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

• Optically clear construction enables direct on-membrane visualization of captured particles without transfer or additional preparation.
• Low protein binding and biologically inert surface properties make track-etched Polycarbonate compatible with cell biology and cytology workflows.
• Offer a smooth, flat glass-like surface specifically designed for microscopy analysis.
• Manufactured with tight pore size control for precise separation of cells and particulates.
• Bulk packaging format provides cost-effective access for high-volume laboratories performing non-critical filtration and sample preparation.

Reproducible particle counting and size distribution analysis start with a membrane surface that captures particles uniformly — the pore consistency documented above ensures your counts reflect the sample, not random variation in the filter. 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.

Wettability

Hydrophilic

• 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.
• Exosome Isolation - Separates extracellular vesicles from larger cell debris using defined pore sizes, preventing contamination in RNA analysis.
• Chemotaxis Migration - Acts as a precise barrier in Boyden chambers to measure cell migration towards chemoattractants without passive diffusion.
• Parasite Detection - Concentrates blood samples to detect microfilariae on a transparent surface, simplifying identification without staining.
