Nuclepore Hydrophilic Membrane, 0.1um Pore Size, 13mm Circle, 100/Pk SKU: 10419501

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10419501

The Whatman 10419501 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. Reproducible separation characteristics define the membrane structure, protecting downstream instruments and preserving sample integrity throughout the filtration process. Ultimately, controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

• Uniform pore density across the membrane surface ensures representative sampling for environmental and biological particulate analysis.
• Bulk packaging format provides cost-effective access for high-volume laboratories performing non-critical filtration and sample preparation.
• 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.
• Low protein binding and biologically inert surface properties make track-etched Polycarbonate compatible with cell biology and cytology workflows.

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. Captured particles sit in a single focal plane on the flat polycarbonate surface, making your microscopic examination faster and particle counts more accurate than with depth filters that trap particles at multiple levels. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Hydrophilic

• Liposome Sizing - Used in extrusion devices to force lipid suspensions through exact pores, creating uniform unilamellar vesicles for drug delivery.
• Parasite Detection - Concentrates blood samples to detect microfilariae on a transparent surface, simplifying identification without staining.
• Asbestos Analysis - Provides a smooth, flat surface for collecting airborne fibers, allowing for direct counting via phase-contrast light microscopy.
• Legionella Recovery - Captures bacteria from hot water samples on a flat plane for direct fluorescent antibody staining and microscope counting.
• Exosome Isolation - Separates extracellular vesicles from larger cell debris using defined pore sizes, preventing contamination in RNA analysis.
• Oceanographic Sampling - Fractionates plankton populations by size in seawater, ensuring precise separation for biomass and diversity studies.
