Nuclepore Hydrophilic Membrane, 0.2um Pore Size, 25mm Circle, 100/Pk SKU: 10417006

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10417006

Precision-manufactured Hydrophilic membrane with a verified 0.2 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Developed with critical workflows in mind, reproducible separation characteristics define the membrane structure, protecting downstream instruments and preserving sample integrity throughout the filtration process. Accordingly, each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• 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.
• Low protein binding and biologically inert surface properties make track-etched Polycarbonate compatible with cell biology and cytology workflows.
• Supplied in bulk non-sterile packaging, offering an economical option for routine clarification and general laboratory filtration tasks.
• Uniform pore density across the membrane surface ensures representative sampling for environmental and biological particulate analysis.

If your protocol requires direct on-membrane analysis by microscopy or culture, the surface characteristics and dimensional tolerances described above give you a substrate that performs consistently from disc to disc. 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

• 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.
• 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.
• Erythrocyte Deformability - Mimics capillary dimensions to test red blood cell flexibility and rheology in clinical hemorheology research.
• Parasite Detection - Concentrates blood samples to detect microfilariae on a transparent surface, simplifying identification without staining.
