Cyclopore Polycarbonate Membrane, 12.0um, 25mm Circle, 100/Pk SKU: 10418552

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10418552

Designed to deliver reproducibility and confidence across critical sample types, the Whatman 10418552 provides the filtration consistency that method validation demands. Precision-manufactured Hydrophilic membrane with a verified 12.0 pore structure delivers consistent retention across the full operating range. For this reason, controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

• Optically clear construction enables direct on-membrane visualization of captured particles without transfer or additional preparation.
• Low protein binding and biologically inert surface properties make track-etched Polycarbonate compatible with cell biology and cytology workflows.
• Supplied in bulk non-sterile packaging, offering an economical option for routine clarification and general laboratory filtration tasks.
• Manufactured with tight pore size control for precise separation of cells and particulates.
• Track-etched Polycarbonate membranes feature perfectly cylindrical pores for absolute fractionation.

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. Under these conditions, low background autofluorescence from polycarbonate membranes keeps your fluorescence microscopy signal-to-noise ratio high, ensuring that the fluorescent labels on your captured particles are what you see — not membrane interference. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

Hydrophilic

• Chemotaxis Migration - Acts as a precise barrier in Boyden chambers to measure cell migration towards chemoattractants without passive diffusion.
• 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.
• Oceanographic Sampling - Fractionates plankton populations by size in seawater, ensuring precise separation for biomass and diversity studies.
• Parasite Detection - Concentrates blood samples to detect microfilariae on a transparent surface, simplifying identification without staining.
• Asbestos Analysis - Provides a smooth, flat surface for collecting airborne fibers, allowing for direct counting via phase-contrast light microscopy.
