Nuclepore Hydrophilic Membrane, 0.08um Pore Size, 47mm Circle, 100/Pk SKU: 10419312

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10419312

The Whatman 10419312 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. Developed with critical workflows in mind, verified 0.08 pore distribution across the Hydrophilic membrane surface guarantees batch-to-batch consistency in particle capture and analyte passage. Taken together, controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

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

Environmental monitoring programs where sample-to-sample comparability determines trend validity benefit directly from the lot-level consistency of these membranes, removing the filter as a variable in your long-term data sets. 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. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.

Hydrophilic

• 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.
• 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.
• Chemotaxis Migration - Acts as a precise barrier in Boyden chambers to measure cell migration towards chemoattractants without passive diffusion.
• Oceanographic Sampling - Fractionates plankton populations by size in seawater, ensuring precise separation for biomass and diversity studies.
