Polycarbonate Track Etch Membrane Disc Filters, 12.0um, 47mm, Hydrophilic, Nonsterile, 100/Pk
GVS SKU: 3027598

Featuring a thin, microporous polycarbonate track etch (PCTE) film with precisely defined cylindrical pores, this 47mm membrane disc delivers controlled 12.0um filtration across heavily particulate samples. The hydrophilic PCTE membrane is produced through a two-step process in which polycarbonate film is exposed to ion particles that create tracks, which are then chemically etched into precise, cylindrical pores. The result is a thin, translucent membrane with a smooth, flat surface that captures all particles larger than the pore size directly on its surface, supplied nonsterile in a 100-disc pack.

Key Polycarbonate Track Etch Membrane Characteristics

• Hydrophilic surface: Although polycarbonate is naturally hydrophobic, the membrane is treated with a wetting agent to make it hydrophilic for aqueous filtration.
• Absolute pore size and density: Precisely defined 12.0um cylindrical pores provide accurate size separation and flow control, capturing particles larger than the pore size on the surface.
• Low protein binding: Minimizes sample loss and supports clean, consistent results.
• Smooth, planar surface: The thin, glass-like surface is ideal for particle identification and microscopic visualization, and resists chemical staining.
• Superior strength: The track etch film maintains pore size and density without stretching during handling and use.

Key Construction Characteristics

• Membrane material: Polycarbonate Track Etch (PCTE).
• Diameter: 47mm disc format.
• Pore size: 12.0um nominal.
• Sterility: Nonsterile.
• Pack: 100 discs per pack.

This PCTE membrane provides reliable, repeatable surface retention that protects sample integrity across demanding filtration workflows. Its precise pore geometry and low protein binding maintain consistent flow and clean separations, while the smooth surface supports clear downstream microscopic examination.

• General Filtration The 12.0um hydrophilic PCTE membrane provides controlled clarification of aqueous samples with surface particle retention.
• Cell-Based Filtration Assays Precise cylindrical pores and low protein binding support cellular separation and reagent flow control in assay workflows.
• Microscopy Sample Preparation The smooth, flat surface captures particles for clear identification and counting under the microscope.
• Prefiltration The large 12.0um pore size makes the membrane well suited to removing larger particulates ahead of finer downstream filters.
• Blood and Plasma Processing Surface capture of cells larger than the pore size supports separation of larger cellular components from liquid samples.
