Polycarbonate Track Etch Membrane Filter Discs, 0.2um, 47mm, White, Nonsterile, 200/Pk
GVS SKU: 1226157

Featuring a thin, microporous polycarbonate track etch (PCTE) film with precisely defined cylindrical pores, this 0.2um, 47mm hydrophilic membrane disc delivers exact size separation across general filtration and analytical workflows. The polycarbonate film is treated with polyvinylpyrrolidone (PVP) to render the naturally hydrophobic material hydrophilic, while the smooth, flat, translucent surface captures all particles larger than the pore size directly on the membrane face. This white, non-gridded, nonsterile disc is supplied in a pack of 200.

Key Polycarbonate Track Etch Membrane Characteristics

• Hydrophilic PVP treatment wets the membrane for aqueous filtration despite polycarbonate's inherently hydrophobic nature.
• Precise cylindrical pores formed through a controlled two-stage track etch process provide a narrow pore distribution and consistent size separation.
• Smooth, flat, translucent surface captures particles on the membrane face, making it well suited to particle identification by optical or electron microscopy.
• Low protein binding and negligible adsorption/absorption support clean results and maximize critical sample recovery.
• Resists chemical staining to minimize background interference during microscopic visualization.

Key Construction Characteristics

• Material: Polycarbonate Track Etch (PCTE) film.
• Format: 47mm membrane disc, white, not gridded.
• Pore size: 0.2um.
• Sterility: Nonsterile.
• Pack: 200 per pack.

This membrane provides reliable, repeatable separations with precisely controlled pore size and density. Its low extractables and negligible filtrate adsorption help maintain sample integrity, while the planar surface keeps captured particles in a single plane for straightforward analysis.

• General Filtration Provides precise particle separation of aqueous samples thanks to its PVP-treated hydrophilic surface and tightly controlled 0.2um pore size.
• Microscopy Sample Preparation The smooth, flat, translucent surface captures particles in a single plane for clear viewing under optical or electron microscopes.
• Blood and Cell Studies Captures cells larger than the pore size on the membrane surface, supporting collection for blood assays and tissue studies.
• High-Purity Filtration Low extractables and negligible adsorption keep filtrate clean for high-purity analytical work.
• Particle Identification Stain-resistant, non-gridded surface minimizes background interference when characterizing retained particulates.
• Prefiltration and Flow Control Narrow pore distribution provides predictable flow control of reagents and protects downstream steps.
