Polycarbonate Track Etch Membrane Disc Filters, 0.8um, 47mm, White, Nonsterile, 100/Pk
GVS SKU: 1215620

Featuring a thin, microporous polycarbonate track etched (PCTE) film with precisely defined, straight-through cylindrical pores, this 0.8um, 47mm membrane disc delivers accurate surface filtration and reliable particle separation. The base polycarbonate is treated with polyvinylpyrrolidone (PVP) to render the membrane hydrophilic, supporting aqueous filtration across general and high-purity applications. Its smooth, translucent surface captures all particles larger than the pore size directly on the membrane face, making it well suited to microscopic visualization and particulate analysis.

Key Polycarbonate Track Etch Membrane Characteristics

• Hydrophilic surface: PVP treatment provides wettability for aqueous filtration while preserving the polycarbonate base structure.
• Defined cylindrical pores: precisely controlled pore size and density allow accurate size separation, capturing all particles larger than the pore size on the surface.
• Low protein binding: minimizes sample loss and supports assay and biological work.
• Chemical stain resistance: the smooth, translucent film resists chemical staining to ease microscopic visualization of captured particles.
• Surface capture mechanism: particles are retained on the flat membrane face rather than within a depth matrix, providing a sharp separation cutoff.

Key Construction Characteristics

• Material: polycarbonate track etched (PCTE) film, white.
• Pore size: 0.8um.
• Diameter: 47mm, not gridded.
• Sterility: nonsterile.
• Pack: 100 per pack.

Each membrane is processed to ensure its physical properties precisely match specification, delivering consistent pore size and density from disc to disc. The smooth, flat surface maintains sample integrity during collection and supports reliable downstream analysis. This combination of defined pore structure and low protein binding provides dependable, repeatable performance in routine filtration and analytical workflows.
