Cyclopore Polycarbonate Membrane, 0.2um, 25mm Circle, 100/Pk SKU: 10417606

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10417606

The Whatman 10417606 combines a controlled pore size distribution with low extractable levels, ensuring the data accuracy that sensitive analytical methods require. Verified 0.2 pore distribution across the Hydrophilic membrane surface guarantees batch-to-batch consistency in particle capture and analyte passage. Working in concert, 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

• Economical bulk packaging supports laboratories with high consumable throughput where individual sterile wrapping is unnecessary.
• Manufactured with tight pore size control for precise separation of cells and particulates.
• Uniform pore density across the membrane surface ensures representative sampling for environmental and biological particulate analysis.
• Track-etched Polycarbonate membranes feature perfectly cylindrical pores for absolute fractionation.
• Low protein binding and biologically inert surface properties make track-etched Polycarbonate compatible with cell biology and cytology workflows.

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. 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. 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.

Wettability

Hydrophilic

• 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.
• Exosome Isolation - Separates extracellular vesicles from larger cell debris using defined pore sizes, preventing contamination in RNA analysis.
• Erythrocyte Deformability - Mimics capillary dimensions to test red blood cell flexibility and rheology in clinical hemorheology research.
• Asbestos Analysis - Provides a smooth, flat surface for collecting airborne fibers, allowing for direct counting via phase-contrast light microscopy.
• Liposome Sizing - Used in extrusion devices to force lipid suspensions through exact pores, creating uniform unilamellar vesicles for drug delivery.
