Nuclepore Hydrophilic Membrane, 0.1um Pore Size, 142mm Circle 25/Pk SKU: 10419531

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10419531

Precision-manufactured Hydrophilic membrane with a verified 0.1 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Precision membrane geometry balances retention sharpness with sustainable flow rates, minimizing the pressure buildup that leads to premature filter replacement. In effect, from raw polymer through final inspection, the manufacturing process is designed to ensure that every membrane disc meets the performance specifications of its grade designation.

Material Specifications

• Offer a smooth, flat glass-like surface specifically designed for microscopy analysis.
• Manufactured with tight pore size control for precise separation of cells and particulates.
• Track-etched Polycarbonate membranes feature perfectly cylindrical pores for absolute fractionation.
• Optically clear construction enables direct on-membrane visualization of captured particles without transfer or additional preparation.
• Supplied in bulk non-sterile packaging, offering an economical option for routine clarification and general laboratory filtration tasks.

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. Captured particles sit in a single focal plane on the flat polycarbonate surface, making your microscopic examination faster and particle counts more accurate than with depth filters that trap particles at multiple levels. 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.

Hydrophilic

• Exosome Isolation - Separates extracellular vesicles from larger cell debris using defined pore sizes, preventing contamination in RNA analysis.
• Chemotaxis Migration - Acts as a precise barrier in Boyden chambers to measure cell migration towards chemoattractants without passive diffusion.
• Asbestos Analysis - Provides a smooth, flat surface for collecting airborne fibers, allowing for direct counting via phase-contrast light microscopy.
• 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.
• Erythrocyte Deformability - Mimics capillary dimensions to test red blood cell flexibility and rheology in clinical hemorheology research.
