Nuclepore Hydrophilic Membrane, 0.8um Pore Size, 25mm Circle, 100/Pk SKU: 10417306

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10417306

The Whatman 10417306 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. Manufactured to exacting specifications, precision membrane geometry balances retention sharpness with sustainable flow rates, minimizing the pressure buildup that leads to premature filter replacement. Each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• Uniform pore density across the membrane surface ensures representative sampling for environmental and biological particulate analysis.
• Packaged without sterilization for applications where downstream sterility is achieved by other means or is not a process requirement.
• 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.
• Track-etched Polycarbonate membranes feature perfectly cylindrical pores for absolute fractionation.

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. Because track-etched pores are uniform in diameter across the entire membrane surface, the retention characteristics you validate during method development remain consistent from disc to disc — eliminating a variable in your quality-critical particle analyses. 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.
• Exosome Isolation - Separates extracellular vesicles from larger cell debris using defined pore sizes, preventing contamination in RNA analysis.
• Legionella Recovery - Captures bacteria from hot water samples on a flat plane for direct fluorescent antibody staining and microscope counting.
• 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.
• Chemotaxis Migration - Acts as a precise barrier in Boyden chambers to measure cell migration towards chemoattractants without passive diffusion.
