Nuclepore Hydrophilic Membrane, 8.0um Pore Size, 25mm Circle, 100/Pk SKU: 10417506

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10417506

Engineered for high retention efficiency and superior chemical stability, the Whatman 10417506 achieves reliable separation results across a broad range of analytical and preparative applications. Precision membrane geometry balances retention sharpness with sustainable flow rates, minimizing the pressure buildup that leads to premature filter replacement. Working in concert, 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.
• Optically clear construction enables direct on-membrane visualization of captured particles without transfer or additional preparation.
• Manufactured with tight pore size control for precise separation of cells and particulates.
• Supplied in bulk non-sterile packaging, offering an economical option for routine clarification and general laboratory filtration tasks.
• Offer a smooth, flat glass-like surface specifically designed for microscopy 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. Polycarbonate's optical clarity when wet allows direct on-membrane visualization without clearing or staining steps, streamlining your microscopy workflow and reducing the sample preparation time between filtration and analysis. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.

Hydrophilic

• Parasite Detection - Concentrates blood samples to detect microfilariae on a transparent surface, simplifying identification without staining.
• Liposome Sizing - Used in extrusion devices to force lipid suspensions through exact pores, creating uniform unilamellar vesicles for drug delivery.
• 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.
• Oceanographic Sampling - Fractionates plankton populations by size in seawater, ensuring precise separation for biomass and diversity studies.
• Erythrocyte Deformability - Mimics capillary dimensions to test red blood cell flexibility and rheology in clinical hemorheology research.
