Nuclepore Hydrophilic Membrane, 8.0um Pore Size, 47mm Circle, 100/Pk SKU: 10417512

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10417512

Engineered for high retention efficiency and superior chemical stability, the Whatman 10417512 achieves reliable separation results across a broad range of analytical and preparative applications. Additionally, precision membrane geometry balances retention sharpness with sustainable flow rates, minimizing the pressure buildup that leads to premature filter replacement. Consequently, each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• Track-etched Polycarbonate membranes feature perfectly cylindrical pores for absolute fractionation.
• Bulk packaging format provides cost-effective access for high-volume laboratories performing non-critical filtration and sample preparation.
• Manufactured with tight pore size control for precise separation of cells and particulates.
• Offer a smooth, flat glass-like surface specifically designed for microscopy analysis.
• Uniform pore density across the membrane surface ensures representative sampling for environmental and biological particulate analysis.

When your analytical method specifies membrane filtration as a sample preparation step, the retention characteristics and extractable profiles documented above allow you to meet method requirements without additional qualification work. In these cases, low background autofluorescence from polycarbonate membranes keeps your fluorescence microscopy signal-to-noise ratio high, ensuring that the fluorescent labels on your captured particles are what you see — not membrane interference. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

Hydrophilic

• Liposome Sizing - Used in extrusion devices to force lipid suspensions through exact pores, creating uniform unilamellar vesicles for drug delivery.
• 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.
• 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.
• Parasite Detection - Concentrates blood samples to detect microfilariae on a transparent surface, simplifying identification without staining.
