Nuclepore Hydrophilic Membrane, 0.8um Pore Size, 47mm Circle, 100/Pk SKU: 10417312

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10417312

The Whatman 10417312 combines a controlled pore size distribution with low extractable levels, ensuring the data accuracy that sensitive analytical methods require. Engineered for demanding applications, a uniform Polycarbonate Track-Etched (PCTE) matrix maintains its rated 0.8 cutoff under the pressures and flow conditions encountered during routine laboratory filtration. 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

• Uniform pore density across the membrane surface ensures representative sampling for environmental and biological particulate analysis.
• Offer a smooth, flat glass-like surface specifically designed for microscopy analysis.
• Non-sterile configuration is suited for analytical sample preparation, mobile phase filtration, and other workflows where pre-sterilization is not required.
• 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.

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. Here, 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.
• Oceanographic Sampling - Fractionates plankton populations by size in seawater, ensuring precise separation for biomass and diversity studies.
• 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.
• Asbestos Analysis - Provides a smooth, flat surface for collecting airborne fibers, allowing for direct counting via phase-contrast light microscopy.
