Polycarbonate Track Etched Membrane Filters, 0.05um, 142mm, Nonsterile, 20/Pk
GVS SKU: 1221290

Featuring a hydrophilic polycarbonate track etched (PCTE) membrane made from a thin polycarbonate film with precisely defined, cylindrical pores, these 142mm membrane discs deliver controlled, surface-capture filtration at a 0.05um pore size. The membrane is treated with polyvinylpyrrolidone (PVP) to render the naturally hydrophobic polycarbonate hydrophilic, producing a thin, translucent film with a smooth, flat surface that captures all particles larger than the pore size directly on its surface. Each disc measures approximately 0.005 to 0.02mm in thickness and is supplied nonsterile in packs of 20.

Key Polycarbonate Track Etched (PCTE) Membrane Characteristics

• Hydrophilic surface: Treated with PVP wetting agent so the membrane wets readily with aqueous solutions.
• Precise pore structure: Cylindrical, track etched pores provide accurate size separation and surface capture of all particles larger than the pore size.
• Smooth, translucent surface: A thin, glass-like planar surface is well suited to particle identification by optical and electron microscopy.
• Low protein binding: Minimizes sample loss and supports clean, consistent results.
• Resists chemical staining: Eases microscopic visualization of collected samples.

Key Construction Characteristics

• Material: Polycarbonate Track Etched (PCTE) film with PVP wetting agent.
• Format: 142mm membrane disc, plain (not gridded).
• Thickness: Approximately 0.005 to 0.02mm.
• Sterility: Nonsterile.
• Pack: 20 discs per pack.

The tightly controlled pore size and density deliver reliable, repeatable size separation while maintaining sample integrity through low protein binding and minimal adsorption. The smooth, translucent film simplifies downstream microscopic examination of retained particles, making these discs well suited to high purity and general filtration workflows.

• General Filtration Provides controlled, surface-capture filtration of aqueous samples at a fine 0.05um pore size.
• High Purity Filtration Low extractables and low protein binding support clean filtration where sample purity is critical.
• Microscopy Sample Preparation The smooth, translucent surface captures particles on its face for clear viewing by optical or electron microscopy.
• Cellular and Blood Assays Precise pore structure suits cellular based filtration assays and separation of cells larger than the pore size.
• Particle Analysis Surface retention of particles larger than the pore size enables accurate particle collection and identification.
• Fine Particulate Capture The 0.05um rating captures very fine particulates and submicron material on the membrane surface.
