Nuclepore Hydrophilic Membrane, 1.0um Pore Size, 293 mm Circle, 25 Pk SKU: 10418739

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10418739

The Whatman 10418739 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. In addition, precision-manufactured Hydrophobic membrane with a verified 1.0 pore structure delivers consistent retention across the full operating range. Altogether, 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.
• Low protein binding and biologically inert surface properties make track-etched Polycarbonate compatible with cell biology and cytology workflows.
• 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.
• Economical bulk packaging supports laboratories with high consumable throughput where individual sterile wrapping is unnecessary.

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. The precisely etched, cylindrical pores of track-etched polycarbonate provide the sharpest size cutoff of any polymeric membrane, giving you near-absolute retention at the rated pore diameter for applications where size-selective capture is critical. 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.

Hydrophobic

• Erythrocyte Deformability - Mimics capillary dimensions to test red blood cell flexibility and rheology in clinical hemorheology research.
• Parasite Detection - Concentrates blood samples to detect microfilariae on a transparent surface, simplifying identification without staining.
• Legionella Recovery - Captures bacteria from hot water samples on a flat plane for direct fluorescent antibody staining and microscope counting.
• Oceanographic Sampling - Fractionates plankton populations by size in seawater, ensuring precise separation for biomass and diversity studies.
• Liposome Sizing - Used in extrusion devices to force lipid suspensions through exact pores, creating uniform unilamellar vesicles for drug delivery.
• Chemotaxis Migration - Acts as a precise barrier in Boyden chambers to measure cell migration towards chemoattractants without passive diffusion.
