Polycarbonate Track Etch (PCTE) Membrane Discs, 0.2um, 47mm, Hydrophilic, Nonsterile, 100/Pk
GVS SKU: 1215612

Featuring a thin, microporous polycarbonate track etch (PCTE) film with precisely defined cylindrical pores, this 47mm membrane disc delivers a 0.2um pore size for high-purity and general filtration. The membrane is produced through a two-step track-etching process in which polycarbonate film is exposed to ion particles that create tracks, which are then chemically etched into precise, cylindrical pores. Although polycarbonate is naturally hydrophobic, this membrane is treated with polyvinylpyrrolidone (PVP) to render it hydrophilic, supporting aqueous and alcoholic samples. The result is a thin, translucent, white film with a smooth, flat surface that captures all particles larger than the pore size directly on its surface.

Key Polycarbonate Track Etch (PCTE) Membrane Characteristics

• Hydrophilic surface: PVP treatment makes the naturally hydrophobic polycarbonate wettable for processing aqueous and alcoholic samples.
• Precise surface capture: Absolutely-rated, narrowly distributed cylindrical pores capture particles on the membrane surface for accurate, reproducible size separation.
• Smooth, glass-like surface: The thin, translucent planar film is well suited to particle identification and microscopy.
• Superior strength: A tensile strength greater than 3,000 psi (207 bar) maintains pore size and density without stretching.
• Low protein binding and low extractables: Minimizes nonspecific binding and helps keep results clean and consistent.

Key Construction Characteristics

• Material: Polycarbonate Track Etch (PCTE) film.
• Format: 47mm membrane disc, white, not gridded.

• General Filtration Provides high-purity, general purpose filtration of aqueous and alcoholic samples with precise surface particle capture.
• Microscopy and Particle Analysis The smooth, translucent surface captures particles on a single plane for accurate particle identification and imaging.
• Blood and Cell Studies Suited to blood assays and removal of red blood cells from plasma where precise pore control is required.
• Microbial Enumeration Narrow pore distribution and surface capture support reproducible collection and counting of microorganisms.
• Reagent Flow Control Uniform cylindrical pores provide controlled flow of reagents through assay formats.
• High-Purity Sample Preparation Low extractables and low protein binding help maintain sample integrity during preparation.
