Nuclepore Hydrophilic Membrane, 1.0um Pore Size, 90mm Circle, 25 Pk SKU: 10418718

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10418718

Designed to deliver reproducibility and confidence across critical sample types, the Whatman 10418718 provides the filtration consistency that method validation demands. Engineered for demanding applications, verified 1.0 pore distribution across the Hydrophobic membrane surface guarantees batch-to-batch consistency in particle capture and analyte passage. With this in mind, 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

• 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.
• 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.
• Optically clear construction enables direct on-membrane visualization of captured particles without transfer or additional preparation.

Reporting filtration parameters alongside your analytical results demands documented pore size, material chemistry, and lot traceability — the membrane specifications above provide the specificity that reviewers and auditors expect. In this context, 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. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Hydrophobic

• Oceanographic Sampling - Fractionates plankton populations by size in seawater, ensuring precise separation for biomass and diversity studies.
• Liposome Sizing - Used in extrusion devices to force lipid suspensions through exact pores, creating uniform unilamellar vesicles for drug delivery.
• Chemotaxis Migration - Acts as a precise barrier in Boyden chambers to measure cell migration towards chemoattractants without passive diffusion.
• Asbestos Analysis - Provides a smooth, flat surface for collecting airborne fibers, allowing for direct counting via phase-contrast light microscopy.
• 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.
