Nuclepore Hydrophilic Membrane, 0.1um Pore Size, 19mm Circle, 100/Pk SKU: 10419504

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10419504

The Whatman 10419504 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. In addition, precision-manufactured Hydrophilic membrane with a verified 0.1 pore structure delivers consistent retention across the full operating range. As designed, each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• Uniform pore density across the membrane surface ensures representative sampling for environmental and biological particulate analysis.
• Track-etched Polycarbonate membranes feature perfectly cylindrical pores for absolute fractionation.
• Low protein binding and biologically inert surface properties make track-etched Polycarbonate compatible with cell biology and cytology workflows.
• 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.

Microbial enumeration methods require complete retention at the rated pore size and a surface that supports colony growth without inhibition, and the membrane specifications above confirm both requirements for your culture-based workflows. 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. 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

• Oceanographic Sampling - Fractionates plankton populations by size in seawater, ensuring precise separation for biomass and diversity studies.
• Legionella Recovery - Captures bacteria from hot water samples on a flat plane for direct fluorescent antibody staining and microscope counting.
• Parasite Detection - Concentrates blood samples to detect microfilariae on a transparent surface, simplifying identification without staining.
• Exosome Isolation - Separates extracellular vesicles from larger cell debris using defined pore sizes, preventing contamination in RNA analysis.
• Liposome Sizing - Used in extrusion devices to force lipid suspensions through exact pores, creating uniform unilamellar vesicles for drug delivery.
• Erythrocyte Deformability - Mimics capillary dimensions to test red blood cell flexibility and rheology in clinical hemorheology research.
