Nuclepore Hydrophilic Membrane, 0.4um Pore Size, 47mm Circle, 100/Pk SKU: 10417112

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10417112

The Whatman 10417112 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. Verified 0.4 pore distribution across the Hydrophilic membrane surface guarantees batch-to-batch consistency in particle capture and analyte passage. In sum, consistent surface properties across the full membrane area support uniform particle capture and reliable results in gravimetric, microscopic, and culture-based analytical workflows.

Material Specifications

• 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.
• Offer a smooth, flat glass-like surface specifically designed for microscopy analysis.

Environmental monitoring programs where sample-to-sample comparability determines trend validity benefit directly from the lot-level consistency of these membranes, removing the filter as a variable in your long-term data sets. Addressing this directly, 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. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

Wettability

Hydrophilic

• Legionella Recovery - Captures bacteria from hot water samples on a flat plane for direct fluorescent antibody staining and microscope counting.
• Liposome Sizing - Used in extrusion devices to force lipid suspensions through exact pores, creating uniform unilamellar vesicles for drug delivery.
• Asbestos Analysis - Provides a smooth, flat surface for collecting airborne fibers, allowing for direct counting via phase-contrast light microscopy.
• Oceanographic Sampling - Fractionates plankton populations by size in seawater, ensuring precise separation for biomass and diversity studies.
• Parasite Detection - Concentrates blood samples to detect microfilariae on a transparent surface, simplifying identification without staining.
• Chemotaxis Migration - Acts as a precise barrier in Boyden chambers to measure cell migration towards chemoattractants without passive diffusion.
