Polycarbonate Track Etch Membrane Disc Filters, 0.1um, 25mm, Hydrophilic, Nonsterile, 100/Pk
GVS SKU: 1215606

Featuring a hydrophilic polycarbonate track etch (PCTE) medium produced from a thin, microporous polycarbonate film with precisely defined cylindrical pores, this 25mm membrane disc delivers exact 0.1um surface capture for high-purity filtration. The film is exposed to ion particles that create tracks through the polymer, which are then chemically etched into precise, cylindrical pores, giving tight control over pore size and density. Each nonsterile disc is supplied 100 per pack.

Key Polycarbonate Track Etch Membrane Characteristics

• Treated with polyvinylpyrrolidone (PVP) for a hydrophilic surface that wets readily in water and aqueous solutions without pre-wetting.
• Absolute, precisely defined cylindrical pores capture particles larger than the pore size directly on the smooth membrane surface.
• Thin, translucent film with a smooth, flat planar surface that is well suited to particle identification by microscopy.
• Low protein binding and resistance to chemical staining ease microscopic visualization and support clean results.
• High tensile strength maintains pore size and density and resists stretching under use.

Key Construction Characteristics

• Polycarbonate track etch (PCTE) membrane material in a 25mm disc format.
• White, non-gridded membrane.
• Nonsterile, supplied 100 per pack.
• Nominal membrane thickness of approximately 5 to 20um (0.005 to 0.02mm).

The track etch process maintains consistent pore geometry so that physical properties match specification disc to disc, providing repeatable surface separation. The smooth, low-binding surface preserves sample integrity and supports clean, reproducible results across filtration and microscopy workflows.

• High-Purity General Filtration Removes particles larger than 0.1um for clarification of liquids in high-purity filtration workflows.
• Microscopy Particle Analysis The smooth, flat, translucent surface captures particles for direct identification and counting by microscopy.
• Cellular-Based Filtration Assays Precisely defined pores support cell-based assays and controlled flow of reagents through assays.
• Blood and Plasma Sample Prep Suited to blood assays, including separation of cells larger than the pore size from sample fluids.
• Reagent Flow Control Uniform cylindrical pores provide consistent flow control for liquids and reagents.
• High-Purity Sample Clarification Low extractables and low protein binding help keep clarified samples clean for downstream analysis.
