Nuclepore Hydrophilic Membrane, 5.0um Pore Size, 25mm Circle, 100/Pk SKU: 10417406

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10417406

Precision-manufactured Hydrophilic membrane with a verified 5.0 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Constructed for reliable operation, precision-manufactured Hydrophilic membrane with a verified 5.0 pore structure delivers consistent retention across the full operating range. In effect, from raw polymer through final inspection, the manufacturing process is designed to ensure that every membrane disc meets the performance specifications of its grade designation.

Material Specifications

• Manufactured with tight pore size control for precise separation of cells and particulates.
• Optically clear construction enables direct on-membrane visualization of captured particles without transfer or additional preparation.
• Track-etched Polycarbonate membranes feature perfectly cylindrical pores for absolute fractionation.
• Offer a smooth, flat glass-like surface specifically designed for microscopy analysis.
• Uniform pore density across the membrane surface ensures representative sampling for environmental and biological particulate analysis.

Scaling your method from development to routine production requires membrane consistency at every lot — the documented specifications of these membranes provide the reproducibility needed to validate the filtration step once. Under these conditions, defined pore geometry gives you a membrane that functions as a precision sieve, capturing particles strictly by size rather than the impaction and diffusion mechanisms that depth filters rely on. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

Hydrophilic

• Erythrocyte Deformability - Mimics capillary dimensions to test red blood cell flexibility and rheology in clinical hemorheology research.
• 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.
• Chemotaxis Migration - Acts as a precise barrier in Boyden chambers to measure cell migration towards chemoattractants without passive diffusion.
• Legionella Recovery - Captures bacteria from hot water samples on a flat plane for direct fluorescent antibody staining and microscope counting.
