Polycarbonate (PCTE) Membrane Filters, 3.0um, 47mm, Hydrophilic, Nonsterile, 100/Pk
GVS SKU: 1215036

Featuring a thin, microporous polycarbonate track etch (PCTE) film with precisely defined cylindrical pores, this 47mm membrane disc delivers an absolute 3.0um pore size for accurate surface separation. Each membrane is produced through a two-step manufacturing process in which a polycarbonate film is bombarded with ions to create tracks, then chemically etched to open uniform, narrowly distributed pores. The result is a thin, translucent membrane with a smooth, flat surface that captures all particles larger than the rated pore size directly on the membrane face. The membrane is treated with polyvinylpyrrolidone (PVP) to render the naturally hydrophobic polycarbonate hydrophilic, allowing aqueous and alcoholic samples to be processed without pre-wetting. This nonsterile, non-gridded, white membrane ships 100 per pack.

Key Polycarbonate (PCTE) Membrane Characteristics

• Hydrophilic surface produced by a PVP wetting treatment for direct use with aqueous and alcoholic samples without pre-wetting.
• Absolute 3.0um pore size with precisely cylindrical, narrowly distributed pores that capture particles larger than the rating on the membrane surface.
• Low protein binding for reliable recovery in cellular and blood-based assays.
• Thin, translucent structure with a smooth, flat surface that resists chemical staining for easier microscopic visualization.
• Superior mechanical strength derived from the integral polycarbonate film.

Key Construction Characteristics

• Single, integral microporous polycarbonate film construction.
• 47mm diameter disc format.
• White, non-gridded membrane surface.
• Nonsterile, supplied 100 discs per pack.

The track etch process yields well-calibrated pore size and uniform pore density, delivering predictable flow rates and consistent particle retention from disc to disc. Surface capture of particulates keeps samples intact for downstream microscopy and analysis, while low protein binding helps preserve sample integrity in cellular and clinical workflows.

• General Filtration The 3.0um absolute pore size supports high-purity, general-purpose filtration of aqueous and alcoholic samples.
• Cellular-Based Filtration Assays Low protein binding and uniform pores make the membrane well suited to cell-based filtration and chemotaxis studies.
• Blood and Plasma Processing Precise surface retention supports removal of red blood cells from plasma and related blood assay preparations.
• Microscopic Particle Analysis The smooth, translucent, stain-resistant surface captures particles on the membrane face for easy microscopic visualization.
• Prefiltration The open 3.0um rating handles larger particulates to protect and prepare samples ahead of finer downstream membranes.
• Reagent Flow Control Defined pore size and density provide controlled flow of reagents through assay formats.
