Polycarbonate Track Etch Membrane Disc Filters, 0.4um, 47mm, Hydrophilic, Nonsterile, 100/Pk
GVS SKU: 1215617

Featuring a thin, microporous polycarbonate track etch (PCTE) film with precisely defined cylindrical pores, this 0.4um, 47mm membrane disc delivers exact surface capture of particles larger than the pore size. Treated with polyvinylpyrrolidone (PVP) to render the naturally hydrophobic polycarbonate base hydrophilic, the membrane wets readily with aqueous samples while maintaining a smooth, flat, translucent surface ideal for microscopic examination. The membrane is supplied white, not gridded, and nonsterile in a pack of 100.

Key Polycarbonate Track Etch Membrane Characteristics

• Hydrophilic surface: PVP treatment makes the polycarbonate film readily wettable for aqueous filtration.
• Absolute pore size: precise, uniform cylindrical pores provide reliable size separation and a narrow pore distribution.
• Surface capture: particles larger than the pore size are retained on the smooth, flat surface rather than within a depth matrix.
• Low protein binding: minimizes sample loss and adsorption during filtration.
• Resists chemical staining: the translucent film eases optical and electron microscopic visualization.

Key Construction Characteristics

• Membrane material: polycarbonate track etch (PCTE).
• Pore size: 0.4um.
• Diameter: 47mm.
• Format: white, not gridded, nonsterile.
• Pack: 100 per pack.

The track etch process yields a thin film whose physical properties precisely fit specification, providing consistent, repeatable filtration performance from disc to disc. The smooth surface and low adsorption help preserve sample integrity for downstream analysis, microscopy, and assay work.
