Nuclepore Hydrophilic Membrane, 0.2um Pore Size, 19mm Circle, 100/Pk SKU: 10417004

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10417004

Precision-manufactured Hydrophilic membrane with a verified 0.2 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. A uniform Polycarbonate Track-Etched (PCTE) matrix maintains its rated 0.2 cutoff under the pressures and flow conditions encountered during routine laboratory filtration. In combination, 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.
• Economical bulk packaging supports laboratories with high consumable throughput where individual sterile wrapping is unnecessary.
• Offer a smooth, flat glass-like surface specifically designed for microscopy 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.

Reporting filtration parameters alongside your analytical results demands documented pore size, material chemistry, and lot traceability — the membrane specifications above provide the specificity that reviewers and auditors expect. Because track-etched pores are uniform in diameter across the entire membrane surface, the retention characteristics you validate during method development remain consistent from disc to disc — eliminating a variable in your quality-critical particle analyses. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Hydrophilic

• Parasite Detection - Concentrates blood samples to detect microfilariae on a transparent surface, simplifying identification without staining.
• 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.
• 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.
