Whatman
NUC PC, 19mm, 0.4um, 100/Pk SKU: 10417104

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10417104

Designed to deliver reproducibility and confidence across critical sample types, the Whatman 10417104 provides the filtration consistency that method validation demands. Supporting this capability, precision membrane geometry balances retention sharpness with sustainable flow rates, minimizing the pressure buildup that leads to premature filter replacement. In sum, each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• Optically clear construction enables direct on-membrane visualization of captured particles without transfer or additional preparation.
• 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.
• Non-sterile configuration is suited for analytical sample preparation, mobile phase filtration, and other workflows where pre-sterilization is not required.
• Low protein binding and biologically inert surface properties make track-etched Polycarbonate compatible with cell biology and cytology workflows.

When your analytical method specifies membrane filtration as a sample preparation step, the retention characteristics and extractable profiles documented above allow you to meet method requirements without additional qualification work. To support this, 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. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

• Erythrocyte Deformability - Mimics capillary dimensions to test red blood cell flexibility and rheology in clinical hemorheology research.
• 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.
• Legionella Recovery - Captures bacteria from hot water samples on a flat plane for direct fluorescent antibody staining and microscope counting.
• Exosome Isolation - Separates extracellular vesicles from larger cell debris using defined pore sizes, preventing contamination in RNA analysis.
• Liposome Sizing - Used in extrusion devices to force lipid suspensions through exact pores, creating uniform unilamellar vesicles for drug delivery.
