Nuclepore Hydrophilic Membrane, 0.1um Pore Size, 90mm Circle, 25/Pk SKU: 10419518

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10419518

The Whatman 10419518 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. Built for consistent results, verified 0.1 pore distribution across the Hydrophilic membrane surface guarantees batch-to-batch consistency in particle capture and analyte passage. Accordingly, each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• Manufactured with tight pore size control for precise separation of cells and particulates.
• 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.
• Bulk packaging format provides cost-effective access for high-volume laboratories performing non-critical filtration and sample preparation.
• 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. To support this, 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. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

Wettability

Hydrophilic

• Parasite Detection - Concentrates blood samples to detect microfilariae on a transparent surface, simplifying identification without staining.
• Erythrocyte Deformability - Mimics capillary dimensions to test red blood cell flexibility and rheology in clinical hemorheology research.
• Exosome Isolation - Separates extracellular vesicles from larger cell debris using defined pore sizes, preventing contamination in RNA analysis.
• Asbestos Analysis - Provides a smooth, flat surface for collecting airborne fibers, allowing for direct counting via phase-contrast light microscopy.
• 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.
