Whatman
Cyclopore Polycarbonate Membrane, 0.4um, 47mm Circle, 100/Pk SKU: 10417712

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10417712

The Whatman 10417712 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. Precision-manufactured Hydrophilic membrane with a verified 0.4 pore structure delivers consistent retention across the full operating range. Each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• Uniform pore density across the membrane surface ensures representative sampling for environmental and biological particulate analysis.
• Low protein binding and biologically inert surface properties make track-etched Polycarbonate compatible with cell biology and cytology workflows.
• Track-etched Polycarbonate membranes feature perfectly cylindrical pores for absolute fractionation.
• Manufactured with tight pore size control for precise separation of cells and particulates.
• Offer a smooth, flat glass-like surface specifically designed for microscopy analysis.

Air monitoring and stack emissions sampling demand a filter medium that withstands the thermal and chemical conditions at your collection point — the material properties described above define the operating envelope for your application. In this context, 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. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

Hydrophilic

• Asbestos Analysis - Provides a smooth, flat surface for collecting airborne fibers, allowing for direct counting via phase-contrast light microscopy.
• 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.
• 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.
• Parasite Detection - Concentrates blood samples to detect microfilariae on a transparent surface, simplifying identification without staining.
