Polycarbonate Track Etch Membrane Filters, 8.0um, 90mm, Hydrophilic, Nonsterile, 30/Pk
GVS SKU: 1215403

Featuring a hydrophilic polycarbonate track etched (PCTE) medium, these 90mm membrane discs provide an 8.0um pore size for precise, surface-capture filtration. The membrane is produced from a thin polycarbonate film exposed to ion particles that create tracks, which are then chemically etched into precise, cylindrical pores. Because pore density and pore size are independently controlled, the membrane delivers tight, well-defined separation. Although polycarbonate is naturally hydrophobic, this version is treated with a wetting agent (PVP) to make it hydrophilic, and the filters are supplied nonsterile in packs of 30.

Key Polycarbonate Track Etch (PCTE) Membrane Characteristics

• Hydrophilic surface: treated with a wetting agent (polyvinylpyrrolidone) so the naturally hydrophobic polycarbonate readily wets out with aqueous samples.
• Precise cylindrical pores: an 8.0um track etched pore structure captures all particles larger than the pore size on the membrane surface.
• Smooth, glass-like surface: the thin, translucent planar surface deposits particles in a single plane, making it ideal for particle identification by optical and electron microscopy.
• Superior strength: a tensile strength of 207 bar (greater than 3000 psi) maintains pore size and density and resists stretching.
• Low protein binding and low extractables: negligible absorption and adsorption maximize critical solution recovery and promote clean, consistent results.

Key Construction Characteristics

• Material: hydrophilic polycarbonate track etched (PCTE) film.
• Format: 90mm membrane disc.
• Sterility: nonsterile.
• Maximum operating temperature: 140 degrees C (284 degrees F).
• Pack: 30 per pack.

This membrane provides dependable surface-capture filtration with even particle distribution across a flat, microscopy-ready plane. Its low binding and low extractable characteristics help preserve sample integrity and support clean, repeatable analytical results.

• Particulate Removal The 8.0um track etched pores capture particles larger than the pore size on the membrane surface for clean separations.
• Microscopy Sample Prep The smooth, glass-like planar surface deposits particles in a single plane for optical and electron microscope examination.
• Blood and Cellular Assays The defined pore structure supports applications such as removal of red blood cells from plasma and other cellular-based work.
• Prefiltration The strong, high-flow membrane serves as a precise prefilter ahead of finer downstream membranes.
• High-Purity General Filtration Low extractables and low protein binding make the membrane suitable for high-purity, general-purpose filtration.
• Flow Control of Reagents The absolute pore size and density provide controlled flow of reagents through assays.
