Polycarbonate Track Etch Membrane Filters, 0.2um, 293mm, Hydrophilic, Nonsterile, 20/Pk
GVS SKU: 1215385

Featuring a thin, microporous polycarbonate film with precisely defined cylindrical pores, this Polycarbonate Track Etch (PCTE) membrane delivers accurate size separation at a 0.2um pore size across a 293mm diameter disc. The membrane is treated with polyvinylpyrrolidone (PVP) to make it hydrophilic, allowing it to process aqueous samples without pre-wetting. Its smooth, glass-like surface captures particles on a single plane, simplifying microscopic and SEM examination.

Key Polycarbonate Track Etch (PCTE) Membrane Characteristics

• Hydrophilic surface: PVP coating wets readily for aqueous and alcoholic samples with no pre-wetting step required.
• Absolute pore rating: precisely cylindrical, narrowly distributed pores enable accurate size separation and reproducible particle retention.
• Low protein binding: minimizes non-specific binding for clean recovery and reliable assay results.
• Smooth, flat surface: translucent film captures particles on a single plane and resists chemical staining for easy microscopic visualization.
• Superior strength: the integral polycarbonate film offers high mechanical strength without sloughing or particle shedding.

Key Construction Characteristics

• Membrane material: Polycarbonate Track Etch (PCTE) film.
• Pore size: 0.2um.
• Diameter: 293mm.
• Sterility: Nonsterile.
• Pack: 20 per pack.

This membrane provides consistent, predictable flow and trusted particle retention for demanding filtration and analytical work. The uniform pore structure supports reproducible results across samples, while the low-binding, smooth surface preserves sample integrity through filtration and downstream microscopic analysis.
