Nuclepore Hydrophilic Membrane, 0.2um Pore Size, 50mm Circle, 100/Pk SKU: 10417014

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10417014

Engineered for high retention efficiency and superior chemical stability, the Whatman 10417014 achieves reliable separation results across a broad range of analytical and preparative applications. Verified 0.2 pore distribution across the Hydrophilic membrane surface guarantees batch-to-batch consistency in particle capture and analyte passage. Because of this, 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.
• Supplied in bulk non-sterile packaging, offering an economical option for routine clarification and general laboratory filtration tasks.
• 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.
• Low protein binding and biologically inert surface properties make track-etched Polycarbonate compatible with cell biology and cytology workflows.

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. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Hydrophilic

• Legionella Recovery - Captures bacteria from hot water samples on a flat plane for direct fluorescent antibody staining and microscope counting.
• Liposome Sizing - Used in extrusion devices to force lipid suspensions through exact pores, creating uniform unilamellar vesicles for drug delivery.
• 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.
• Oceanographic Sampling - Fractionates plankton populations by size in seawater, ensuring precise separation for biomass and diversity studies.
• Chemotaxis Migration - Acts as a precise barrier in Boyden chambers to measure cell migration towards chemoattractants without passive diffusion.
