Polycarbonate Track Etched Membrane Sheets, 0.8um, 8x10in, Hydrophilic, Nonsterile, 30/Pk
GVS SKU: 1222030

Featuring a thin, microporous polycarbonate track etched (PCTE) film with precisely defined 0.8um cylindrical pores, these 8 x 10 inch membrane sheets capture all particles larger than the pore size directly on the surface for clean, reliable separations. Produced through a two-step track etching process, the membrane offers tight control over pore size and density, and its smooth, translucent, glass-like surface makes it well suited to particle identification by microscopy. The polycarbonate is treated with a wetting agent (PVP) to provide a hydrophilic membrane for aqueous filtration.

Key Polycarbonate Track Etched (PCTE) Membrane Characteristics

• Hydrophilic surface: PVP treatment makes the naturally hydrophobic polycarbonate hydrophilic for filtration of aqueous samples.
• Surface capture, defined pores: precisely defined cylindrical pores capture all particles larger than 0.8um on the membrane surface for size separation.
• Smooth, glass-like surface: the thin, translucent planar surface is ideal for particle identification and optical or electron microscopy.
• Low protein binding and low extractables: minimizes nonspecific adsorption and helps keep tests clean for consistent results.
• High purity manufacture: produced under cleanroom conditions for exceptionally low contaminant levels.

Key Construction Characteristics

• Format: flat membrane sheets, 8 x 10 inches, supplied 30 per pack.
• Pore size: 0.8um.
• Wettability: hydrophilic.
• Sterility: nonsterile.
• Maximum use temperature: 140 degrees C.

The track etched structure maintains pore size and density under load, delivering predictable flow control and reproducible retention. With low absorption and adsorption of filtrate, the membrane maximizes critical solution recovery and protects sample integrity. The smooth surface supports straightforward downstream analysis of retained particles.
