Cyclopore Polycarbonate Membrane, 0.1um, 47mm Circle, 100/Pk SKU: 10419412

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10419412

The Whatman 10419412 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. Furthermore, quality-controlled manufacturing ensures the filtration medium delivers the retention efficiency and throughput that demanding laboratory protocols require. Altogether, precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

• Offer a smooth, flat glass-like surface specifically designed for microscopy analysis.
• 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.
• Bulk format reduces per-unit packaging waste and cost, appropriate for routine particulate removal and clarification where aseptic handling is not specified.

If your protocol requires direct on-membrane analysis by microscopy or culture, the surface characteristics and dimensional tolerances described above give you a substrate that performs consistently from disc to disc. In response, 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. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

• Oceanographic Sampling - Fractionates plankton populations by size in seawater, ensuring precise separation for biomass and diversity studies.
• 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.
• Parasite Detection - Concentrates blood samples to detect microfilariae on a transparent surface, simplifying identification without staining.
