Nuclepore Hydrophilic Membrane, 1.0um Pore Size, 47mm Circle, 100/Pk SKU: 10418712

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10418712

The Whatman 10418712 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. On the performance side, verified 1.0 pore distribution across the Hydrophobic membrane surface guarantees batch-to-batch consistency in particle capture and analyte passage. By design, precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

• Offer a smooth, flat glass-like surface specifically designed for microscopy analysis.
• Packaged without sterilization for applications where downstream sterility is achieved by other means or is not a process requirement.
• Track-etched Polycarbonate membranes feature perfectly cylindrical pores for absolute fractionation.
• 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.

Air monitoring and stack emissions sampling demand a filter medium that withstands the thermal and chemical conditions at your collection point — the material properties described above define the operating envelope for your application. In practice, the precisely etched, cylindrical pores of track-etched polycarbonate provide the sharpest size cutoff of any polymeric membrane, giving you near-absolute retention at the rated pore diameter for applications where size-selective capture is critical. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Hydrophobic

• Chemotaxis Migration - Acts as a precise barrier in Boyden chambers to measure cell migration towards chemoattractants without passive diffusion.
• Liposome Sizing - Used in extrusion devices to force lipid suspensions through exact pores, creating uniform unilamellar vesicles for drug delivery.
• 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.
• 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.
