Nuclepore Hydrophilic Membrane, 1.0um Pore Size, 25mm Circle, 100/Pk SKU: 10418706

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10418706

Designed to deliver reproducibility and confidence across critical sample types, the Whatman 10418706 provides the filtration consistency that method validation demands. Precision-manufactured Hydrophobic membrane with a verified 1.0 pore structure delivers consistent retention across the full operating range. 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

• Low protein binding and biologically inert surface properties make track-etched Polycarbonate compatible with cell biology and cytology workflows.
• Manufactured with tight pore size control for precise separation of cells and particulates.
• Offer a smooth, flat glass-like surface specifically designed for microscopy analysis.
• Bulk format reduces per-unit packaging waste and cost, appropriate for routine particulate removal and clarification where aseptic handling is not specified.
• Optically clear construction enables direct on-membrane visualization of captured particles without transfer or additional preparation.

Whether your method calls for gravimetric analysis, particle visualization, or microbial enumeration, the pore consistency and surface uniformity documented above ensure that your results reflect the sample — not the filter. Polycarbonate's optical clarity when wet allows direct on-membrane visualization without clearing or staining steps, streamlining your microscopy workflow and reducing the sample preparation time between filtration and analysis. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Wettability

Hydrophobic

• Asbestos Analysis - Provides a smooth, flat surface for collecting airborne fibers, allowing for direct counting via phase-contrast light microscopy.
• Exosome Isolation - Separates extracellular vesicles from larger cell debris using defined pore sizes, preventing contamination in RNA analysis.
• Chemotaxis Migration - Acts as a precise barrier in Boyden chambers to measure cell migration towards chemoattractants without passive diffusion.
• 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.
• Legionella Recovery - Captures bacteria from hot water samples on a flat plane for direct fluorescent antibody staining and microscope counting.
