Polycarbonate Track Etched Membrane, 20um, 8x10in, Hydrophilic, Nonsterile, 30/Pk
GVS SKU: 1221231

Featuring a thin, translucent polycarbonate film with precisely defined cylindrical pores, this Polycarbonate Track Etched (PCTE) membrane sheet measures 8 x 10 inches and provides 20um surface filtration in a nonsterile, hydrophilic format supplied 30 per pack. Because polycarbonate is naturally hydrophobic, the film is treated with a wetting agent to render it hydrophilic, supporting reliable wet-out for aqueous samples while capturing all particles larger than the pore size on its surface.

Key Polycarbonate Track Etched (PCTE) Membrane Characteristics

• Hydrophilic surface: Treated with a wetting agent so aqueous samples wet out readily across the membrane.
• Surface capture: A smooth, flat film retains all particles larger than the 20um pore size directly on the surface for precise size separation.
• Glass-like planar surface: The thin, translucent film makes the membrane well suited to particle identification and optical analysis by microscopy.
• Low protein binding: Minimizes sample loss and supports consistent recovery of critical solutions.
• Resists chemical staining: Eases microscopic visualization of captured particulate.

Key Construction Characteristics

• Material: Polycarbonate Track Etched (PCTE) film with precise, cylindrical track-etched pores.
• Format: Flat membrane sheet measuring 8 x 10 inches.
• Sterility: Nonsterile.
• Pack: 30 sheets per pack.

This membrane delivers controlled, surface-based filtration that maintains pore size and density for repeatable separations. Its low protein binding and smooth surface help preserve sample integrity and ease downstream microscopic analysis, making it a dependable choice for high-purity and general-purpose filtration work.
