Nuclepore Hydrophilic Membrane, 3.0um Pore Size, 13mm Circle, 100/Pk SKU: 10418301

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10418301

Engineered for high retention efficiency and superior chemical stability, the Whatman 10418301 achieves reliable separation results across a broad range of analytical and preparative applications. Additionally, a uniform Polycarbonate Track-Etched (PCTE) matrix maintains its rated 3.0 cutoff under the pressures and flow conditions encountered during routine laboratory filtration. Lot-level verification of pore size, flow rate, and physical dimensions ensures that membrane performance remains predictable when scaling from method development to routine analysis.

Material Specifications

• Offer a smooth, flat glass-like surface specifically designed for microscopy analysis.
• Track-etched Polycarbonate membranes feature perfectly cylindrical pores for absolute fractionation.
• Uniform pore density across the membrane surface ensures representative sampling for environmental and biological particulate analysis.
• Manufactured with tight pore size control for precise separation of cells and particulates.
• Supplied in bulk non-sterile packaging, offering an economical option for routine clarification and general laboratory filtration tasks.

Maintaining accreditation under ISO 17025 or similar quality frameworks requires documented traceability at every step — the specification compliance of each membrane lot supports your ongoing audit readiness. Meeting this challenge, 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. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

Hydrophobic

• Parasite Detection - Concentrates blood samples to detect microfilariae on a transparent surface, simplifying identification without staining.
• Liposome Sizing - Used in extrusion devices to force lipid suspensions through exact pores, creating uniform unilamellar vesicles for drug delivery.
• Exosome Isolation - Separates extracellular vesicles from larger cell debris using defined pore sizes, preventing contamination in RNA analysis.
• Oceanographic Sampling - Fractionates plankton populations by size in seawater, ensuring precise separation for biomass and diversity studies.
• Erythrocyte Deformability - Mimics capillary dimensions to test red blood cell flexibility and rheology in clinical hemorheology research.
• Chemotaxis Migration - Acts as a precise barrier in Boyden chambers to measure cell migration towards chemoattractants without passive diffusion.
