Cyclopore Polycarbonate Membrane, 12.0um, 47mm Circle, 100/Pk SKU: 10418550

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10418550

Precision-manufactured Hydrophilic membrane with a verified 12.0 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Constructed for reliable operation, precision-manufactured Hydrophilic membrane with a verified 12.0 pore structure delivers consistent retention across the full operating range. Precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

• Offer a smooth, flat glass-like surface specifically designed for microscopy analysis.
• Track-etched Polycarbonate membranes feature perfectly cylindrical pores for absolute fractionation.
• Manufactured with tight pore size control for precise separation of cells and particulates.
• 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.

Microbial enumeration methods require complete retention at the rated pore size and a surface that supports colony growth without inhibition, and the membrane specifications above confirm both requirements for your culture-based workflows. With these demands in mind, 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. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Hydrophilic

• Exosome Isolation - Separates extracellular vesicles from larger cell debris using defined pore sizes, preventing contamination in RNA analysis.
• 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.
• Legionella Recovery - Captures bacteria from hot water samples on a flat plane for direct fluorescent antibody staining and microscope counting.
• 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.
